Precision CNC machining parts With eccentric pieces, directly or indirectly, the work piece clamping body, known as the eccentric clamping body. There are two types of eccentric pieces, that is, and the curve of eccentricity eccentric circle, which, due to a round eccentric structure is simple and easy to manufacture and is widely used.
Precision CNC machining parts Eccentric clamping processing is easy to operate, rapid clamp, the disadvantage of clamping force and clamping trip are small. Not generally used in cutting force, Precision CNC machiningparts vibration small there is no centrifugal force of the impact of the processing.
