CNC precision parts processing that can be carved on the hair! ! !

CNC precision part processing is a technology that uses CNC machine tools for processing. It has many advantages such as high production efficiency, high degree of automation, and large processing range. And it plays a vital role in new product development.

The most worth mentioning is the speed and precision of precision parts processing, speed and precision are two extremely important indicators of metal processing. Using high-precision and high-speed processing technology can greatly improve the processing efficiency and product quality and grade, while also greatly reducing the production cycle and delivery time, it is also to improve market competitiveness.

When CNC precision parts are processed at high speeds, the cutting speed of turning and milling has reached more than 5000～8000m/min; the spindle rotation speed is more than 30,000 rpm (some up to 100,000 rpm); the movement of the table Speed (feeding speed): when the resolution is 1 micron, above 100m/min (some to 200m/min), when the resolution is 0.1um, above 24m/min; the automatic tool change speed is within 1 second Within; the feed rate of small line segment interpolation reaches 12m/min.

In terms of machining accuracy, in the past 10 years, the machining accuracy of ordinary CNC machine tools has been increased from 10um to 5um, and the precision machining center has been increased from 3 to 5um to 1 to 1.5um, and ultra-precision machining accuracy has begun to enter the nano level (0.01um).

The thickness of the hair diameter is about 60 to 90 microns, and the precision of CNC precision parts processing has been comparable to carving on the hair.
