How to solve the problem of deformation of stainless steel cut by wire cutting

Dear, I am glad to answer for you: how to prevent deformation of wire cutting stainless steel method is as follows: iron or steel can be used to fix the workpiece with a magnet to prevent the deformation of the workpiece during processing, and the specific operation is done when the workpiece is cut halfway, and the magnet is used to absorb and fix it in the cut direction.

If the wire cutting is to cut the punch, you can first leave a margin on the periphery of the punch, turn around and do not cut it, and then cut it according to the correct dimensions, so that the cut punch will not be deformed; Similarly, when cutting the die, leave a margin along the inner shape, cut one circle, and then cut one circle according to the correct die size. The die cut in this way will also not be deformed.

Summary. Hello is happy to answer for you, your question is: wire cutting can not cut stainless steel?

The answer is: stainless steel is a heat-resistant material, which is difficult to cut, and its easy twisting and deformation will shrink the seam and short-circuit the molybdenum wire with the workpiece. Therefore, when cutting stainless steel, the pulse width and current should be increased, so that the cut gap becomes wider and not easy to short circuit, and the coolant must be clean and have enough flow, so that the carbide can be washed out in time and the cut can be cooled in time.

In the actual cutting process, it is often encountered that the workpiece is not cut without moving, and sometimes it cannot be cut at all, which generally occurs when cutting high thickness or cutting difficult-to-process materials such as stainless steel, and the fundamental reason is.

The working solution does not have the characteristics of good patting and erosion products, and the emergency solution is to add some detergent or increase the concentration of the working solution, but the most fundamental way is to change the good working solution. ”

How to cut stainless steel material wire cutting method: (1) Flame cutting: The cost of flame cutting equipment is low and it is the only economical and effective means of cutting thick metal plates, but it has its shortcomings in thin plate cutting.

Compared with plasma, the heat-affected zone of flame cutting is much larger, and the thermal deformation is relatively large. (2) Laser cutting: The laser cutting equipment can cut stainless steel plates below 30mm, and the oxygen in the laser beam can cut 40mm thick carbon steel, but a thin oxide film will be formed on the cutting surface after oxygenation cutting.

3) Wire cutting: EDM wire cutting is referred to as wire cutting. It is developed on the basis of EDM perforation and forming processing.

It has not only enabled the development of the application of EDM, but also replaced the EDM perforation and forming process in some aspects.

Hello, dear. When wire cutting, the following measures need to be taken to prevent deformation due to high temperature and severe vibration that may cause deformation of the workpiece:1

Select the appropriate cutting conditions: The appropriate cutting conditions should be selected according to the workpiece material, thick section clumps, shape and other factors, and the parameters such as cutting speed, electrode current and voltage should be strictly controlled. 2.

Use of coolant: During the cutting process, it is necessary to use enough coolant to cool the workpiece to prevent overheating and deforming the workpiece. 3.

Fix the workpiece: Before cutting, you should make sure that the workpiece is firmly fixed to avoid wobbling when cutting. 4.

Workpiece preheating: For relatively thick workpieces, it can be preheated before cutting, so that the temperature is evenly distributed, so as to reduce the wind and dry chain risk of workpiece deformation during cutting. 5.

Reasonable gas protection: In the process of cutting the cherry blossoms, the shielding gas should be reasonably sprayed to prevent the interference of impurities in the air to the cutting process, so as to ensure the quality of the cutting surface.
