The difference between high-speed drilling and milling machining center and CNC machining

The drilling and milling machining center is a machine tool that is gradually separated from the traditional machining center machine tools according to the development needs of the special machine for the purpose of improving production efficiency.

The drilling and milling machining center can perform both drilling and tapping processing, as well as milling processing of parts. It also combines the advantages of both drilling and tapping centers and machining centers.

Because the spindle rotation speed of the drilling and milling center is basically above 10,000rpm, for example, the drilling and milling center of our Dongguan PTJ Precision Hardware Co., Ltd. all use spindles mainly from 12000-20000rpm, and some can reach 30,000rpm. The rotation speed of the spindle of a traditional machining center is much higher, so it is generally called a high-speed drilling and milling machining center.

Characteristics of high-speed drilling and milling machining center

For those parts with smaller size, less machining allowance, and processing technology based on drilling and tapping, the large body and large stroke of the traditional machining center have a certain inhibitory effect on improving production efficiency. In addition, the feed The speed and spindle speed can not meet the technological requirements of high-quality parts. The high-speed drilling and milling machining center just solves these problems: the small body is generally used, the stroke is basically less than 600mm, the worktable becomes smaller, the load of the entire machine tool is also smaller, and the motion inertia that needs to be overcome during the processing is also small In addition, under the same power, the feed rate of the machine tool is naturally faster; the spindle speed is higher, and the processing quality is improved accordingly.
