The high-speed spindle with high quality and high rigidity plays an important role in improving the efficiency and performance of machine tools.
The high-speed spindle with a taper of 40 is designed as a reliable and simple device. It is supported by four high-precision permanent grease lubricated high-speed bearings. The spindle of DNM series machine tools in Dooshan Machining Center is driven by a 15kW (20Hp) AC motor with a large torque. The output torque can reach 106 N.m. The power is transmitted through a heavy-duty tooth drive belt without slipping. It can improve thermal stability and reduce vibration.
Two face contact and oil cooler for DNM series of Dou Shan machining center：
The two-sided spindle positioning system ensures that the cone and end face of the machine tool are in contact with the Zou Falan cone and end face at the same time. The spindle cooling system makes the cooling oil circulate to maintain constant temperature, thus ensuring the high accuracy of the machine tool and not affected by ambient temperature and cutting conditions.
