Advances in computers and biophysics have started a micro miniature revolution that allows scientists to envision and in some cases actually build microscopic machines.

Collecting ring is a key part in micro motor. It is widely used in revolution transformer and autosyn. The injection quality of the part relates to the property and life span of motor.

The applications of micro-cutting processing technology to the machining of 3d precision micro components evoked the great technological revolution in the field of micro-manufacturing.
