Why Choose Fiber Laser for Stainless Steel, Mild Steel and Aluminum, etc., ?
More companies than ever before are investing in fiber lasers. While the automotive industry was undoubtedly the early adopter, this relatively new solution is being snapped up across the board and when you consider the advantages, it’s easy to see why. 

The sheer speed of fiber laser markers makes them the first choice for customers looking to increase efficiency. They’re the fastest laser marking technology at their wavelength, delivering marking times of less than 1 second for some applications. While older, more established laser technology is available-including diode-pumped solid-state (DPSS) lasers, lamp-pumped lasers, and carbon dioxide (CO2) lasers-none can beat a fiber laser for combined mark speed and quality. 
This means fiber lasers can break new ground. For example, 1 of Laser Lines’ customers is an automotive component manufacturer that needs to mark serial codes exceptionally fast-in under half a second-which wouldn’t be possible with any other type of laser. 

Despite being faster, fiber lasers are energy-efficient compared to the alternatives. Not only does this result in reduced power consumption, but it also helps make the system simpler, smaller, and more reliable.
Fiber laser technology uses basic air cooling rather than an additional chiller unit, which would be costly and cumbersome. With many businesses finding both cash and floor space in short supply, compact and efficient fiber laser marking solutions are proving to be the right fit.

The life expectancy of a fiber laser far exceeds that of other laser solutions. In fact, the diode module in a fiber laser typically last 3 times longer than other technologies. Most lasers have a life of around 30,000 hours, which typically equates to about 15 years’ use. 
Fiber lasers have an expected life of around 100,000 hours, which means about 45 years’ use. Saying that, will companies still be using the same fiber laser in 45 years? I doubt it! Regardless, this option does deliver an impressive return on investment.

About us

For most manufacturers, buying an industrial laser cutting machine is a major investment. It’s not just the initial price you pay, but the fact that the purchase will have a great impact on the entire manufacturing process. If the wrong equipment is chosen, you have to live with the decision for quite a long time. It is not unusual to see manufacturers keep a laser for 7 to 10 years.
Do you know the best way to go about purchasing a laser cutting machine? Even if you currently own one, how long ago did you buy it, and what has changed since then?
This CZPT should help you in making a capital purchase decision that will drive your manufacturing operations to new heights.

What’s the Application?

Perhaps the real question is, “Should I even be buying a laser cutting machine?” For many reasons, investing in a different cutting system may make more sense for a company’s manufacturing activities. Investigating all available options can minimize any possible regrets in the future.

Do We Really Need to Invest in Laser Cutting?

A company that doesn’t have a laser cutting machine generally subcontracts the work to 1 or several job shops with that capability. This scenario doesn’t involve a lot of risk and can work if you have some flexibility with lead times.
But there will come that time when you have to ask yourself if it is time for the company to bring laser cutting in-house. This has to be considered even if the business relationship with the subcontractor is great.
How do you know if it is the right time to own a laser? Look at how much you are spending monthly for laser-cut parts. In the words of Henry Ford, “If you need a machine and don’t buy it, then you will ultimately find that you have paid for it and don’t have it.”

What Is the True Cost of Running the Equipment?

With such a large investment, a manufacturer needs to know at what level of efficiency the equipment is operating. You need to know more than just if the machine is running or not running. This is where equipment performance monitoring comes in.
It’s important for you to find out if software can measure the laser cutting machine’s overall equipment efficiency (OEE) in real time. If so, can the software be used for your other laser cutting machines, if you have them, so that you might discover “hidden capacity” where you thought there was none?
With the cost of about 1 percent of the equipment price, monitoring software can provide a 10 to 50 percent productivity gain with paybacks of less than 4 months.

What Can Be Done to Make the Purchasing Decision Easier?

Answering these questions and obtaining quotes based on the feedback can be used to narrow down the selection of the supplier of a laser cutting machine to 2 to 3 sources. From there you need to find the right model, ask the right questions during equipment demonstrations, and work toward an acceptable price. Remember, there are many important items to discuss during the final negotiation.
The purchase of such a machine can be an overwhelming task. That’s why it might make sense to join an industry association, such as the Fabricators & Manufacturers Association, to network with manufacturing peers to learn from them, or even seek out the assistance of someone that has been through or is familiar with this type of industrial equipment purchase. Such an effort likely would prove to be worthwhile.


How to Calculate the Diameter of a Worm Gear

worm shaft
In this article, we will discuss the characteristics of the Duplex, Single-throated, and Undercut worm gears and the analysis of worm shaft deflection. Besides that, we will explore how the diameter of a worm gear is calculated. If you have any doubt about the function of a worm gear, you can refer to the table below. Also, keep in mind that a worm gear has several important parameters which determine its working.

Duplex worm gear

A duplex worm gear set is distinguished by its ability to maintain precise angles and high gear ratios. The backlash of the gearing can be readjusted several times. The axial position of the worm shaft can be determined by adjusting screws on the housing cover. This feature allows for low backlash engagement of the worm tooth pitch with the worm gear. This feature is especially beneficial when backlash is a critical factor when selecting gears.
The standard worm gear shaft requires less lubrication than its dual counterpart. Worm gears are difficult to lubricate because they are sliding rather than rotating. They also have fewer moving parts and fewer points of failure. The disadvantage of a worm gear is that you cannot reverse the direction of power due to friction between the worm and the wheel. Because of this, they are best used in machines that operate at low speeds.
Worm wheels have teeth that form a helix. This helix produces axial thrust forces, depending on the hand of the helix and the direction of rotation. To handle these forces, the worms should be mounted securely using dowel pins, step shafts, and dowel pins. To prevent the worm from shifting, the worm wheel axis must be aligned with the center of the worm wheel’s face width.
The backlash of the CZPT duplex worm gear is adjustable. By shifting the worm axially, the section of the worm with the desired tooth thickness is in contact with the wheel. As a result, the backlash is adjustable. Worm gears are an excellent choice for rotary tables, high-precision reversing applications, and ultra-low-backlash gearboxes. Axial shift backlash is a major advantage of duplex worm gears, and this feature translates into a simple and fast assembly process.
When choosing a gear set, the size and lubrication process will be crucial. If you’re not careful, you might end up with a damaged gear or 1 with improper backlash. Luckily, there are some simple ways to maintain the proper tooth contact and backlash of your worm gears, ensuring long-term reliability and performance. As with any gear set, proper lubrication will ensure your worm gears last for years to come.
worm shaft

Single-throated worm gear

Worm gears mesh by sliding and rolling motions, but sliding contact dominates at high reduction ratios. Worm gears’ efficiency is limited by the friction and heat generated during sliding, so lubrication is necessary to maintain optimal efficiency. The worm and gear are usually made of dissimilar metals, such as phosphor-bronze or hardened steel. MC nylon, a synthetic engineering plastic, is often used for the shaft.
Worm gears are highly efficient in transmission of power and are adaptable to various types of machinery and devices. Their low output speed and high torque make them a popular choice for power transmission. A single-throated worm gear is easy to assemble and lock. A double-throated worm gear requires 2 shafts, 1 for each worm gear. Both styles are efficient in high-torque applications.
Worm gears are widely used in power transmission applications because of their low speed and compact design. A numerical model was developed to calculate the quasi-static load sharing between gears and mating surfaces. The influence coefficient method allows fast computing of the deformation of the gear surface and local contact of the mating surfaces. The resultant analysis shows that a single-throated worm gear can reduce the amount of energy required to drive an electric motor.
In addition to the wear caused by friction, a worm wheel can experience additional wear. Because the worm wheel is softer than the worm, most of the wear occurs on the wheel. In fact, the number of teeth on a worm wheel should not match its thread count. A single-throated worm gear shaft can increase the efficiency of a machine by as much as 35%. In addition, it can lower the cost of running.
A worm gear is used when the diametrical pitch of the worm wheel and worm gear are the same. If the diametrical pitch of both gears is the same, the 2 worms will mesh properly. In addition, the worm wheel and worm will be attached to each other with a set screw. This screw is inserted into the hub and then secured with a locknut.

Undercut worm gear

Undercut worm gears have a cylindrical shaft, and their teeth are shaped in an evolution-like pattern. Worms are made of a hardened cemented metal, 16MnCr5. The number of gear teeth is determined by the pressure angle at the zero gearing correction. The teeth are convex in normal and centre-line sections. The diameter of the worm is determined by the worm’s tangential profile, d1. Undercut worm gears are used when the number of teeth in the cylinder is large, and when the shaft is rigid enough to resist excessive load.
The center-line distance of the worm gears is the distance from the worm centre to the outer diameter. This distance affects the worm’s deflection and its safety. Enter a specific value for the bearing distance. Then, the software proposes a range of suitable solutions based on the number of teeth and the module. The table of solutions contains various options, and the selected variant is transferred to the main calculation.
A pressure-angle-angle-compensated worm can be manufactured using single-pointed lathe tools or end mills. The worm’s diameter and depth are influenced by the cutter used. In addition, the diameter of the grinding wheel determines the profile of the worm. If the worm is cut too deep, it will result in undercutting. Despite the undercutting risk, the design of worm gearing is flexible and allows considerable freedom.
The reduction ratio of a worm gear is massive. With only a little effort, the worm gear can significantly reduce speed and torque. In contrast, conventional gear sets need to make multiple reductions to get the same reduction level. Worm gears also have several disadvantages. Worm gears can’t reverse the direction of power because the friction between the worm and the wheel makes this impossible. The worm gear can’t reverse the direction of power, but the worm moves from 1 direction to another.
The process of undercutting is closely related to the profile of the worm. The worm’s profile will vary depending on the worm diameter, lead angle, and grinding wheel diameter. The worm’s profile will change if the generating process has removed material from the tooth base. A small undercut reduces tooth strength and reduces contact. For smaller gears, a minimum of 14-1/2degPA gears should be used.

Analysis of worm shaft deflection

To analyze the worm shaft deflection, we first derived its maximum deflection value. The deflection is calculated using the Euler-Bernoulli method and Timoshenko shear deformation. Then, we calculated the moment of inertia and the area of the transverse section using CAD software. In our analysis, we used the results of the test to compare the resulting parameters with the theoretical ones.
We can use the resulting centre-line distance and worm gear tooth profiles to calculate the required worm deflection. Using these values, we can use the worm gear deflection analysis to ensure the correct bearing size and worm gear teeth. Once we have these values, we can transfer them to the main calculation. Then, we can calculate the worm deflection and its safety. Then, we enter the values into the appropriate tables, and the resulting solutions are automatically transferred into the main calculation. However, we have to keep in mind that the deflection value will not be considered safe if it is larger than the worm gear’s outer diameter.
We use a four-stage process for investigating worm shaft deflection. We first apply the finite element method to compute the deflection and compare the simulation results with the experimentally tested worm shafts. Finally, we perform parameter studies with 15 worm gear toothings without considering the shaft geometry. This step is the first of 4 stages of the investigation. Once we have calculated the deflection, we can use the simulation results to determine the parameters needed to optimize the design.
Using a calculation system to calculate worm shaft deflection, we can determine the efficiency of worm gears. There are several parameters to optimize gearing efficiency, including material and geometry, and lubricant. In addition, we can reduce the bearing losses, which are caused by bearing failures. We can also identify the supporting method for the worm shafts in the options menu. The theoretical section provides further information.

Types of Screw Shafts

Screw shafts come in various types and sizes. These types include fully threaded, Lead, and Acme screws. Let’s explore these types in more detail. What type of screw shaft do you need? Which 1 is the best choice for your project? Here are some tips to choose the right screw:

Machined screw shaft

The screw shaft is a basic piece of machinery, but it can be further customized depending on the needs of the customer. Its features include high-precision threads and ridges. Machined screw shafts are generally manufactured using high-precision CNC machines or lathes. The types of screw shafts available vary in shape, size, and material. Different materials are suitable for different applications. This article will provide you with some examples of different types of screw shafts.
Ball screws are used for a variety of applications, including mounting machines, liquid crystal devices, measuring devices, and food and medical equipment. Various shapes are available, including miniature ball screws and nut brackets. They are also available without keyway. These components form a high-accuracy feed mechanism. Machined screw shafts are also available with various types of threaded ends for ease of assembly. The screw shaft is an integral part of linear motion systems.
When you need a machined screw shaft, you need to know the size of the threads. For smaller machine screws, you will need a mating part. For smaller screw sizes, the numbers will be denominated as industry Numeric Sizes. These denominations are not metric, but rather in mm, and they may not have a threads-per-inch designation. Similarly, larger machine screws will usually have threads that have a higher pitch than those with a lower pitch.
Another important feature of machine screws is that they have a thread on the entire shaft, unlike their normal counterparts. These machine screws have finer threads and are intended to be screwed into existing tapped holes using a nut. This means that these screws are generally stronger than other fasteners. They are usually used to hold together electronic components, industrial equipment, and engines. In addition to this, machine screws are usually made of a variety of materials.

Acme screw

An Acme screw is the most common type of threaded shaft available. It is available in a variety of materials including stainless steel and carbon steel. In many applications, it is used for large plates in crushing processes. ACME screws are self-locking and are ideal for applications requiring high clamping force and low friction. They also feature a variety of standard thread forms, including knurling and rolled worms.
Acme screws are available in a wide range of sizes, from 1/8″ to 6″. The diameter is measured from the outside of the screw to the bottom of the thread. The pitch is equal to the lead in a single start screw. The lead is equal to the pitch plus the number of starts. A screw of either type has a standard pitch and a lead. Acme screws are manufactured to be accurate and durable. They are also widely available in a wide range of materials and can be customized to fit your needs.
Another type of Acme screw is the ball screw. These have no back drive and are widely used in many applications. Aside from being lightweight, they are also able to move at faster speeds. A ball screw is similar to an Acme screw, but has a different shape. A ball screw is usually longer than an Acme screw. The ball screw is used for applications that require high linear speeds. An Acme screw is a common choice for many industries.
There are many factors that affect the speed and resolution of linear motion systems. For example, the nut position and the distance the screw travels can all affect the resolution. The total length of travel, the speed, and the duty cycle are all important. The lead size will affect the maximum linear speed and force output. If the screw is long, the greater the lead size, the higher the resolution. If the lead length is short, this may not be the most efficient option.

Lead screw

A lead screw is a threaded mechanical device. A lead screw consists of a cylindrical shaft, which includes a shallow thread portion and a tightly wound spring wire. This spring wire forms smooth, hard-spaced thread convolutions and provides wear-resistant engagement with the nut member. The wire’s leading and trailing ends are anchored to the shaft by means appropriate to the shaft’s composition. The screw is preferably made of stainless steel.
When selecting a lead screw, 1 should first determine its critical speed. The critical speed is the maximum rotations per minute based on the natural frequency of the screw. Excessive backlash will damage the lead screw. The maximum number of revolutions per minute depends on the screw’s minor diameter, length, assembly alignment, and end fixity. Ideally, the critical speed is 80% of its evaluated critical speed. A critical speed is not exceeded because excessive backlash would damage the lead screw and may be detrimental to the screw’s performance.
The PV curve defines the safe operating limits of a lead screw. This relationship describes the inverse relationship between contact surface pressure and sliding velocity. As the PV value increases, a lower rotation speed is required for heavier axial loads. Moreover, PV is affected by material and lubrication conditions. Besides, end fixity, which refers to the way the lead screw is supported, also affects its critical speed. Fixed-fixed and free end fixity are both possible.
Lead screws are widely used in industries and everyday appliances. In fact, they are used in robotics, lifting equipment, and industrial machinery. High-precision lead screws are widely used in the fields of engraving, fluid handling, data storage, and rapid prototyping. Moreover, they are also used in 3D printing and rapid prototyping. Lastly, lead screws are used in a wide range of applications, from measuring to assembly.

Fully threaded screw

A fully threaded screw shaft can be found in many applications. Threading is an important feature of screw systems and components. Screws with threaded shafts are often used to fix pieces of machinery together. Having fully threaded screw shafts ensures that screws can be installed without removing the nut or shaft. There are 2 major types of screw threads: coarse and fine. When it comes to coarse threads, UTS is the most common type, followed by BSP.
In the 1840s, a British engineer named Joseph Whitworth created a design that was widely used for screw threads. This design later became the British Standard Whitworth. This standard was used for screw threads in the United States during the 1840s and 1860s. But as screw threads evolved and international standards were established, this system remained largely unaltered. A new design proposed in 1864 by William Sellers improved upon Whitworth’s screw threads and simplified the pitch and surface finish.
Another reason for using fully threaded screws is their ability to reduce heat. When screw shafts are partially threaded, the bone grows up to the screw shaft and causes the cavity to be too narrow to remove it. Consequently, the screw is not capable of backing out. Therefore, fully threaded screws are the preferred choice for inter-fragmentary compression in children’s fractures. However, surgeons should know the potential complication when removing metalwork.
The full thread depth of a fully threaded screw is the distance at which a male thread can freely thread into the shaft. This dimension is typically 1 millimeter shy of the total depth of the drilled hole. This provides space for tap lead and chips. The full-thread depth also makes fully threaded screws ideal for axially-loaded connections. It is also suitable for retrofitting applications. For example, fully threaded screws are commonly used to connect 2 elements.

Ball screw

The basic static load rating of a ball screw is determined by the product of the maximum axial static load and the safety factor “s0”. This factor is determined by past experience in similar applications and should be selected according to the design requirements of the application. The basic static load rating is a good guideline for selecting a ball screw. There are several advantages to using a ball screw for a particular application. The following are some of the most common factors to consider when selecting a ball screw.
The critical speed limit of a ball screw is dependent on several factors. First of all, the critical speed depends on the mass, length and diameter of the shaft. Second, the deflection of the shaft and the type of end bearings determine the critical speed. Finally, the unsupported length is determined by the distance between the ball nut and end screw, which is also the distance between bearings. Generally, a ball screw with a diameter greater than 1.2 mm has a critical speed limit of 200 rpm.
The first step in manufacturing a high-quality ball screw is the choice of the right steel. While the steel used for manufacturing a ball screw has many advantages, its inherent quality is often compromised by microscopic inclusions. These microscopic inclusions may eventually lead to crack propagation, surface fatigue, and other problems. Fortunately, the technology used in steel production has advanced, making it possible to reduce the inclusion size to a minimum. However, higher-quality steels can be expensive. The best material for a ball screw is vacuum-degassed pure alloy steel.
The lead of a ball screw shaft is also an important factor to consider. The lead is the linear distance between the ball and the screw shaft. The lead can increase the amount of space between the balls and the screws. In turn, the lead increases the speed of a screw. If the lead of a ball screw is increased, it may increase its accuracy. If not, the lead of a ball screw can be improved through preloading, lubrication, and better mounting accuracy.
