How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

Various parts of precision CNC machining


1. Parts with high precision requirements

 

The precision requirements of precision CNC machining parts mainly refer to the precision requirements of size, shape, position and surface, and the surface precision mainly refers to the surface roughness. Because the CNC lathe has good rigidity, high precision in manufacturing and tool setting, and can easily and accurately perform manual compensation and automatic compensation, it can process shaft parts with high dimensional accuracy. In some cases, it can achieve the effect of turning instead of grinding. In addition, because the motion of the CNC lathe is realized by high-precision interpolation and servo drive, it can process parts with high shape accuracy requirements such as straightness, roundness, and cylindricity.

 

Because the CNC lathe can complete a lot of processing content in one clamping, it can effectively improve the position accuracy of the parts, and the processing quality is stable. The CNC lathe has the function of cutting at constant linear speed, so it can not only cnc machine parts with small and uniform surface roughness, but also suitable for turning parts with different surface roughness requirements. Generally, the machining accuracy of CNC lathes can reach 0.001mm, and the surface roughness Ra can reach 0.16μm (precision CNC lathes can reach 0.02μm).

 

2. Parts with small surface roughness values

 

The precision CNC machining numerical control lathe has a constant linear speed cutting function, which can machine parts with small and uniform surface roughness values. The problem is that the surface roughness depends on the feed rate and cutting speed when the material, the finishing allowance and the tool have been determined. The cutting speed changes, resulting in inconsistent surface roughness after turning. Using the constant line cutting function of the CNC lathe, you can choose the best line speed to cut cones, spheres and end faces, so that the surface roughness values ​​after turning are small and consistent. .

 

3. Parts with complex surface contour shapes

 

Because the precision  titanium machining CNC lathe has linear and circular interpolation functions (some CNC lathes also have some non-arc curve interpolation functions), it can turn complex shapes composed of arbitrary straight lines and various flat curves. Body parts, including list curves that cannot be described by equations that are processed by fitting calculations. As shown in Figure 4-1, the molding surface of the closed cavity of the shell part cannot be machined on an ordinary lathe, but it can be easily machined on a CNC lathe.
