The power, speed, torque and accuracy of imported motorized spindle are higher than those of domestic motorized spindle, but the volume is much smaller and the service life is much longer. The best brand of imported motorized spindle is Reckerth motorized spindle from Germany, and the milling motorized spindle with HSK40 interface has a rotating speed of 30000rpm, a power of 1 1.5kw, a torque of 7.5um, and an outer diameter of only 140 mm. The domestic motorized spindle with the same torque and power should have an outer diameter of at least 220 mm. It is recommended to make a domestic cutter motorized spindle.
Guangzhou Haozhi and Jingdiao spindles are the best in China, followed by Wuxi, such as Wuxi Bohua, Jingjiang and Changzhou! There are spindles in other places, but the quality is basically the same.
The domestic motorized spindle market is chaotic. After professional market research, the ranking of domestic electric spindles is as follows: Guangzhou Haozhi Electric Spindle, Shanghai Tiansijia Precision Machinery, Luo Yang Shaft Research Technology, Jiangsu Xinglun Electromechanical Co., Ltd. and Jiangsu Chen Xing Electromechanical Co., Ltd., and others are very cheap, with poor service and quality.
