CNC machining usually refers to laptop digital control precision machining, CNC machining lathes, CNC machining milling machines, CNC machining uninteresting and milling devices, and so forth.

CNC machining advantages:
one.
The variety of tooling is tremendously decreased, and intricate tooling is not needed to approach parts with sophisticated designs. If you want to modify the condition and size of the component, you only need to have to modify the component processing system, which is appropriate for new solution improvement and modification.
2. The processing good quality is steady, the processing precision is large, and the repeatability is large, which is appropriate for the processing needs of plane.
three. The generation efficiency is higher in the circumstance of multi-range and tiny batch generation, which can lessen the time for creation planning, equipment instrument adjustment and process inspection, and decreases the reducing time due to the use of the best chopping sum.
four. It can process complex profiles that are hard to approach by traditional techniques, and even procedure some unobservable processing parts.

Automatic lathe is a large-functionality, higher-precision, minimal-sounds tool-type automated lathe. It is an computerized processing machine instrument that controls the processing plan through a cam (CNC is also a sort of automatic lathe, right here refers to a non-CNC automated lathe).

Positive aspects of computerized lathe processing:
one. Automated processing: no manual operation is needed, and sophisticated components can be processed at the same time with external circle, spherical surface, conical floor, arc surface, stage, groove, embossing, drilling, tapping, die, slicing and other procedures. It can be carried out in 1 processing.
two.Large handle precision: the precision of the machine instrument spindle can get to .003mm, the good adjustment of the slider is managed by a micrometer, and the dimensional handle precision can achieve .005mm. The bare minimum slicing feed can be managed to .005, and the roughness of the areas (copper components) can be as minimal as Ra0.04-.08.
three. Automatic feeding: the feeding system instantly feeds the principal shaft, and the equipment routinely stops and alarms when the material is concluded, and the processing procedure does not need guide viewing of the material, attaining a totally automated manufacturing approach. 1 operator can work a number of equipment at the identical time.
four. Higher creation effectiveness: a machining process is concluded for each and every revolution of the cam. Several resources can be cut at the very same time, the processing efficiency is very substantial, and the processing efficiency has the positive aspects that CNC can not match.

Sheet steel processing is called sheet metal processing. Sheet metal elements are slender-plate hardware elements that can be processed by stamping, bending, stretching and other signifies.

The primary procedures are:
Pressure riveting, growing riveting, pulling mother, pulling riveting, riveting, chamfering, bending, forming, chopping, blanking, blanking, punching, punching convex hull, punching and tearing, punching, tapping, leveling , Back enamel, drilling, chamfering, punching, countersinking, flattening, punching mesh, reaming.

The materials commonly utilised in sheet metal processing are cold-rolled sheet (SPCC), scorching-rolled sheet (SHCC), galvanized sheet (SECC, SGCC), copper (CU), brass, red copper, beryllium copper, aluminum sheet (6061, 5052 , 1571, 1060, 6063, duralumin, and many others.), stainless steel (SUS301, SUS304).

Stamping processing is the manufacturing technology of item components with certain condition, dimensions and performance by implies of the power of standard or particular stamping products, so that the sheet metal is directly subjected to deformation pressure in the mold and deformed. It is 1 of the principal approaches of plastic functioning (or push operating) of metals.

Rewards of stamping processing:
1.The creation performance of stamping processing is substantial, and the procedure is handy, and it is effortless to understand mechanization and automation. The number of strokes of regular presses can reach dozens of occasions for each minute, and the higher-pace pressure can achieve hundreds or even 1000’s of moments per moment, and 1 punching piece might be received for each stamping stroke.
2. Considering that the die makes certain the dimension and condition precision of the stamping elements, and usually does not injury the surface quality of the stamping areas, and the lifestyle of the die is normally extended, the good quality of the stamping is steady and the interchangeability is excellent.
three. Stamping can method components with a vast range of measurements and complicated shapes, this kind of as stopwatches as little as clocks, as massive as auto longitudinal beams, masking components, etc., in addition the cold deformation hardening result of the substance during stamping, the energy and stiffness of stamping are higher.
four. Stamping usually does not create chips and scraps, consumes considerably less material, and does not demand other heating tools, so it is a substance-preserving and energy-conserving processing technique, and the cost of stamping areas is low.

Surface area therapy is a process of artificially forming a surface area layer with various mechanical, actual physical and chemical properties of the substrate on the floor of the substrate.

Specifying a Ball Screw

When you need a high-quality ball screw, it is important to select one with the proper dimensions and specifications. When you are looking for the best product, you should consider features such as preloading, surface finish, and internal return system. You can learn more about these features in this article. If you’re unsure which type of ball screw to select, contact a reputable supplier for further guidance. To find the best product for your needs, click here!

Brinelling

When specifying a Brinelling ball screw, it is crucial to know how much axial load it can safely bear. The static load capacity, which is given in the catalogue, applies only to pure axial loading, and any radial load that is smaller than 5% of the axial load won’t pose a problem. For more information, contact a CZPT engineer. Brinelling ball screw service life calculation should be performed using the following data:
Preload: The amount of load a ball screw can handle during a single revolution. Preload is the load applied before the ball screw starts moving, and the load is usually between five and ten percent of the dynamic capacity. However, a ball screw that is subject to vibration will experience higher preload, requiring more frequent lubrication. The resulting mechanical stress may cause the ball screw to buckle, or cause the nut to re-circulate the balls.
Critical ball speed: The maximum speed at which the ball can move through the ball nut is called the critical ball speed. In contrast, running the ball screw at its critical shaft speed can lead to excessive vibrations, leading to premature failure of the end support bearings and brinelling of the ball track. Thus, it is recommended to operate a ball screw at a lower speed than the critical ball speed to prevent brinelling and plastic deformation of the balls.
False brinelling: False brinelling is a form of Fretting. False brinelling occurs when the bearings are not rotating. The movement will result in depressions or wear marks in the bearing raceway. This will cause noise, wear, and eventual fatigue. If these conditions persist, a newer ball screw should be used to test the system. The machine should be run for several hours and tested before replacing the bearing.

Preloading

The process of preloading ball screws minimizes backlash by applying pressure to the threads in the opposite direction of the screw’s direction of rotation. It prevents any movement of the screw relative to the nut. Various methods are used for preloading. A common one is to use oversized balls inside the ball nut. A double nut system may also be used. Both methods are equally effective. Regardless of the method used, the end result is the same – minimal backlash and increased efficiency.
In the conventional method of preloading ball screws, the motors operate simultaneously in opposite directions, causing them to have a relative motion of approximately equal magnitudes. This reduces the frictional resistance of the system, resulting in rapid traverse. The system is able to operate with minimal backlash during 110 inches of travel, reducing the heat developed by the drive nuts and the problems associated with ball screw heating. Moreover, this method can be used in a wide range of applications.
Another method of preloading ball screws is known as the ball-select method. This method includes the use of over-sized balls that force the balls into more contacts with the screw and nut than a normal ball screw. The advantage of this method is that it reduces backlash because the balls are not machined to high tolerances. The disadvantage of this method is that the ball screw will cost more to manufacture than a standard ball screw and nut.
A conventional design includes a mechanical mechanism that uses a series of balls to rotate a shaft. The problem of backlash is exacerbated by the mass of the shaft. The mechanical system is more complex than necessary and often requires a lot of effort. The present invention eliminates these problems by providing an improved method and apparatus for driving ball screws. This method provides a more efficient preload force that is dynamically adjustable while the mechanism is operating. The method can also improve friction and wear.

Internal return system

There are two different types of ball screws. The first type is external and the second is internal. The external type uses return tubes that protrude from the ball nut and extend above and around the outside of the screw. The internal type uses a single tube that spans the ball track, while the more common design uses multiple tubes spanning 1.5 to 3.5 ball tracks. The internal system involves a single return tube and several pickup fingers that guide the balls into the tubes.
The external return tube design is an easier, less expensive choice. The external ball return system has limited space but can handle a wide range of shaft diameters and leads. However, its physical size makes it incompatible with many high-speed applications. Therefore, careful consideration should be given to the mounting options. Internal ball return systems are best suited for small leads and ball sizes. Those that need a high speed will likely benefit from the external ball return system.
Internal ball screw technology has also kept pace with the demands of linear drive systems. Ball screw technology is now more durable than ever. Robust internal ball return systems circulate ball bearings through a solid pickup pin. These deflectors help the balls return to the screw in the correct location. They are crucial components in computer-controlled motion control systems and wire bonding. If you’re interested in the latest advances in linear screw technology, contact us today.
Ball screws are superior to lead screws in many ways. Ball screws are more efficient than lead screws, converting 90% of rotational motion into linear motion. As a result, they are more expensive than lead screws and acme screws. They also provide a smoother movement over the entire travel range. Furthermore, they require less power for the same performance. It’s no wonder that the ball screw is so popular in many different applications.

Surface finish

The surface finish of a ball screw is one of the key factors in determining the performance of the system. A ball screw with a good surface finish has superior performance in rolling resistance, backlash, and wear characteristics. However, it is critical to improve the surface finish of a ball screw to achieve precision movement, low wear, and low noise. To achieve this, special wire brushes will be used to polish precision-ground shafts.
For a ball screw to perform well, it must be hard, have a smooth surface, and retain lubricant. The surface finish of a ball screw should be smooth, free of cracks, and retain the lubricant well. Cracks and annealing are both undesirable during the manufacturing process, so a quality machine should be used for its surface finish. During the production process, a CBN cutting insert with full round or gothic arch profile can be used to achieve a high-quality surface finish.
Another finishing operation used in the manufacture of ball screws is lapping. Lapping improves surface quality and travel variation. It involves complex relative movements of abrasive particulates with the workpiece. This removes a thin layer of material from the workpiece, improving its surface quality and dimensional accuracy. The lapping process can be carried out under low-pressure conditions. It also enhances the friction torque and lubrication.
In lapping experiments, friction torque has the largest influence on travel variation and surface roughness. A friction torque of about one N x m is optimum. In addition, rotational speed has only a minimal effect. The best combination of these parameters is 1-1.5 N x m and 30 rpm. The minimum surface finish of a ball screw is around 800 mesh. The smallest variation in travel is observed at around half-way through the travel.

Lubrication

Proper lubrication of ball screw assemblies is critical to maintain optimum performance and life. Ball screw assemblies should be lubricated with grease, which is introduced directly into the ball nut. The lubrication port can be located at various locations on the product, including on the flange or in the external threads of the ball nut. Some ball nuts also feature a zerk fitting for easier lubrication.
The lubrication of ball screws is required in the case of operating conditions over 100oC. The minimum load for a ball screw is usually realized with a preload force. The lubricant is conveyed through the narrow lubrication gap due to the relative movement of the two surfaces. The increased viscosity of the lubricant enables separation of the contact surfaces. To avoid over-lubrication, it is important to check the lubricant level regularly.
The oil used in lubrication of ball screw assemblies can be either mineral or synthetic. The oil is composed of mineral or synthetic oil, additives, and a thickening agent, such as lithium or bentonite. Other thickening agents include lithium, barium complexes, or aluminum. The lubricant grade NLGI is a widely used classification for lubricating greases. It is not sufficient to choose a specific type of lubricant for a particular application, but it provides a qualitative measure.
Despite being essential to the performance of a ball screw, lubrication is also essential to its lifespan. Different types of lubricant offer corrosion protection. Before using a lubricant, make sure to thoroughly clean and dry the ball screw. If there is any buildup of dirt, it may damage the screw. To prevent this from occurring, you can use a solvent or lint-free cloth. Lubrication of ball screw assemblies can greatly extend the life of the assembly.
