1.The power head spindle adopts BT40 internal cooling rigid precision spindle, which can use carbide internal cooling tools with high precision and efficiency. It is also equipped with a hydraulic tool cylinder, which is very convenient for loading and unloading tools. The spindle is driven by a high-power spindle motor, the spindle speed is 30-3000r/min, and the speed range is wide.
2.The design has been optimised to increase the rigidity of the machine so that it can not only perform drilling but also milling and tapping.
3.The numerical control adopts German Siemens 808D, and is equipped with a upper computer to facilitate the storage and input of workpiece processing program, which is easy to operate.
4.The equipped ball screw pair, linear guide rail pair, electrical parts, servo motor, frequency converter, etc. are supplied by well-known manufacturers at home and abroad, with few startup failures.
