CNC drilling machine is the production and processing of an important piece of equipment, and the high price of such equipment, so that the choice should be cautious, be sure to choose their own production for CNC drilling. Select CNC drilling machine not only has a great impact on the production stability, to improve the processing efficiency is even more important. So how to choose it, generally from the following indicators to choose the right CNC drilling machine: CNC milling machine
1. Drilling machine console stability and rigidity
Targus machines in order to ensure the stability and rigidity of the drilling machine, choose high-quality raw materials to ensure that drilling in the processing of high-precision, to prevent distortion, deformation and so on.
2 shaft speed and stability
There are currently two types of spindles used, one is to scroll the pumping speed up to 80,000 rpm; the other for the air bearings, the maximum speed up to 12 million revolutions. In general, rolling bearings are better for use because of their high longitudinal load capacity. Of course, some drill bits also need to focus on inspection, some drill replacement consumes a long time, and is not conducive to maintenance, many drill bits have become consumables will also lose a lot of money, and some require maintenance every day.

3. Three-dimensional coordinate system (X, Y, Z axis) calibration
Screw-driven stepper motors offer higher feed efficiency, but new products have also been used with servo motors, feed-efficient drilling machines up to 20% - 40%, Z-axis rotation speed, and materials processed Generally does not affect the efficiency of production, less impact on work efficiency.
4. Workbench moving speed and the stability of the table
Workbench kinematic efficiency previously decided by the guide rail material, the general use of flotation as a workbench processing materials, flotation worktable to move more convenient and more flexible. CNC milling machine
