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

Working principle of slow wire processing

 Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t

What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

What are the methods for disassembling cnc machining bearings?

Cnc machining is an automated machine tool that can be processed efficiently and has many functions. The bearing is a component processed by cnc, and its main function is to support the rotation of the machine, reduce the friction coefficient during its movement and ensure its reversal accuracy. In this chapter, we mainly describe the methods for disassembling the bearing.

1. Percussion

The time of striking will converge on the inner ring of the CNC machined bearing. This method is relatively simple, but it is easier to harm the bearing. When disassembling, place it on the underground object pad of the bearing, and then tap it with a hammer to remove the bearing.

2. Pull out method

Using a special pull tool, only need to rotate the handle, the cnc machined bearing can be pulled out. In the meantime, it should be noted that the pull tool must be stuck on the end face of the bearing inner ring and the bending angle of the pull tool is less than 90°.

What are the methods for disassembling cnc machining bearings?

3. Push method

This method can be completed with a press, and it is relatively safe for cnc machining of bearings, but it should be noted that the focus of the press should be placed on the center of the shaft.

4. Hot dismantling method

Pour a 100° bearing oil pot on the CNC machined bearing. The principle of thermal expansion and contraction is that the bearing will expand after being heated. At this time, it can be pulled out with a pull tool. Use this method to be smaller and avoid being scalded.

5. Induction heating method

This method is better. Induction current occurs in the cnc machining bearing ring, and then the bearing will heat up and swell, so that we can disassemble the spindle more conveniently.
