In the field of metal cnc machining and spinning engineering, spinning is a new technology for chipless forming and processing of metal products. This molding technology has the advantages of good deformation conditions, good product performance, small dimensional tolerance, high material utilization, and wide range of products. However, when the CNC spinning machine is processing, the mold will deform. Many people don’t know much about it. In fact, as long as the deformation rules are mastered, this kind of deformation can be prevented. Let’s take a look at how to prevent the mold. The problem of processing deformation.

1. The structure design of CNC spinning machine molds should be reasonable, the thickness should not be too disparate, and the shape should be symmetrical. For CNC spinning machine molds with large deformations, the deformation rules must be mastered and machining allowances reserved. For large, precise and complex molds, combinations can be used structure.

2. Reasonably select the heating temperature and control the heating speed. For precision and complex molds, slow heating, preheating and other balanced heating methods can be used to reduce mold heat treatment deformation.

3. Under the premise of ensuring the hardness of the CNC spinning machine mold, try to use pre-cooling, graded cooling quenching or warm quenching processes. For some sophisticated and complex molds, pre-heat treatment, aging heat treatment, quenching and tempering nitriding heat treatment can be used to control The accuracy of CNC spinning machine molds.

4. When repairing spinning mold blisters, pores, wear and other defects early on, use repair equipment with small thermal impact such as cold welders to avoid deformation during the repair process.
