Introduction of automatic cutting process of mold structure surface

The close integration and mutual promotion of the cutting process and high-efficiency cutting tools have greatly improved production efficiency and shortened the mold manufacturing cycle. As a mold processing company, we are developing towards internationalization in terms of the improvement of CNC processing technology, the unified planning of CNC tools, and the selection of tool equipment. Through the summary of processing experience in recent years and the solution of difficult on-site processing problems, we The level of cutting processing has been continuously improved, which has made the most basic pavement for CNC automatic processing and improving production efficiency.

Automatic processing of mold structure surface

Nowadays, many domestic mold manufacturers can complete automatic processing of some curved surfaces on CNC machine tools, and the structural surface is easily damaged due to the tool vibration when it involves deep cavity processing. In addition, there are impurities during the processing of the rough surface due to the casting itself. Difficult factors such as blastholes, blisters, or uneven machining allowances have always been manually processed by manual operations, and even the operator cannot prevent tool damage in time when taking care of the processing. If you want to have the same level of competition as foreign advanced mold companies, you must overcome this problem.

We explored the mold materials used by our company according to the actual use situation on the site, combined with the theoretical parameters of the tools, and worked out a suitable tool to facilitate the correct selection of tools and cutting parameters during programming. In addition, a large number of extended tool holder assembly machine chuck cutters are used for deep cavity surface processing, instead of long cutting edge tools. In use, we also considered the rigidity of the tool holder after lengthening, and the adverse effects caused by resonance during cutting, so we chose the taper tool holder, and adopted a small cutting depth, high speed, high feed. The speed processing method reduces the damage of the tool to the greatest extent, and also increases the processing efficiency several times. Now through the preparation of the program, the mold structure surface can be automated unmanned processing on the CNC machine tool.
