An important means to improve the process parameters of the fast wire processing is multiple cutting

Multiple cutting is like removing the machining allowance through roughing, semi-finishing and finishing in conventional gold processing. The processing effect is self-evident. Therefore, whether high-precision machine tools or ordinary machine tools use multiple cutting processes, including slow wire cutting machine tools, it is also through multiple cutting to achieve its high precision, high finish. But for China's fast-moving wire cutting machine can use multiple cutting technology, I believe that we must analyze the key to achieve multiple cutting on the fast-cut wire cutting machine on the machine with high repeat positioning accuracy, so that the wire has a certain Dynamically balanced position and narrow dynamic range of variation. The important factors affecting the above changes are:

  1. Axial and radial runout of the guide wheel and bearing.

  2. The radial runout of the wire cartridge and the vibration of the wire frame.

3. The wire is shaken due to the uneven elongation of the wire after being heated.

4. Due to the throwing effect of the wire on the high speed wire, the wire and the guide wheel change point.

5. The disturbance of the working fluid injection pressure is unstable to the electrode wire.

6. Discharge of the discharge wire to the wire.

Therefore, as long as we eliminate or reduce the above factors on the dynamic position of the wire, we can achieve stable multiple cutting on the fast wire machine.
