Advantages of high-speed electric spindle in mold cutting processing

Molds are widely used in the field of industrial molding. When processing molds, in order to improve the surface quality and processing efficiency, especially for the finishing of the mold closing surface and parting line, high-speed cutting machine tools are usually used with high-speed electric spindles. In order to realize the direct processing of tool steel and cast iron molds, especially semi-finishing and finishing.

The high-speed spindle is the core component of the high-speed cutting machine tool, which determines the cutting speed, machining accuracy and application range that the high-speed cutting machine tool can achieve. The maximum speed of high-speed electric spindle can reach 100,000 revolutions/min, which is more than ten times that of ordinary machine tools. The motor power can generally meet the processing requirements of molds.

1. Improve production efficiency.

The high-speed electric spindle has the characteristics of high speed and large torque, and the maximum speed can reach 100,000RPM. It can process very precise and smooth parts, save other processes, and greatly improve production efficiency.

2. Improve processing quality.

Hard cutting process the final surface to improve the surface quality and shape accuracy (not only the surface roughness is low, but also the surface brightness is high), which is more advantageous for the mold processing of complex curved surfaces.

3. The mold is not easy to deform.

During high-speed cutting, most of the cutting heat is taken away by the flying chips of the workpiece, and the workpiece is basically kept in a cold state, so it is particularly suitable for the production of parts that are prone to thermal deformation.

4. Simplify mold processing procedures.

For a variety of difficult-to-machine materials, high-speed cutting can be achieved to obtain very high surface quality, reduce or even eliminate spark discharge and manual polishing procedures, which greatly simplifies the mold processing process.
