Why do We Use High-speed Cutting for Plastic Injection Tooling?

When processing and producing the plastic injection tooling, many factories adopt high-speed cutting technology, so what are the benefits of high-speed cutting?

The tool and workpiece can tolerate high temperature during high-speed cutting, which extends the life of the device under many conditions. On the other hand, when applying high-speed cutting applications, the cutting volume is shallow, and the cutting time of the edge is extremely short. That is, the feeding time is shorter than the heat propagation time.

Low cutting force enables small and consistent tool bending. It is combined with the constant machining allowance required for each tool and process, which is one of the prerequisites for efficient and safe machining.

Since the typical depth of cut in high-speed cutting is shallow, the radial forces on the tool and spindle are low, which increases the wear of spindle bearings, guide rails, and ball screws. Speed cutting and axial milling are also good combinations, which has a small impact on the spindle bearing. With this method, a tool with a long overhang can be used without the risk of vibration.

High-productivity cutting of small-size parts, such as rough machining, semi-finishing, and finishing, is economical when the total material removal rate is relatively low.

It reduces the number of clamping times for injection mold processing. Besides, the injection mold's geometric accuracy can be improved by cutting, and the manual rest can be increased, and the trial time can be extended. Also, the application of CAM system and workshop-oriented programming to assist in the formulation of process plans through the process plan to improve the application rate of machine tools and workshops, thereby significantly shortening the production cycle, improving production efficiency, and enhancing the market competitiveness of injection mold factories.
