(2)Applications:  
it’s widely used in the motor field, such as wiper motor, vacuum cleaner motor, mixer motor, window lifter motor, condenser motor, power tool motor, DC motor, etc.

(3) Machine function and characteristic
Equipped with lubrication device and aluminum alloy frame, this machine features advance technology and modern shape, has easy operation system and self-checking system.
Meanwhile, this machine can be equipped with an automatic feeding device to achieve a fully automatic operation. PLC and touch screen control. Cutter feeding and cutting is controlled by servo motor.

Servo motor drives the belt rotating, meanwhile, the friction of flat belt and rotor surface make the rotor shaft high speed rotating on V block. Equipped with lubrication device and aluminum alloy frame, this machine features advance technology and modern shape, has easy operation system and self-checking
