防鐵屑與冷卻液，防止污染內部結構。
卡盤本體與部件經淬火處理，采用長效潤滑，確保高精度與較長的使用壽命。
離心力補償，適合高－低壓夾緊。
An internal floating cam makes it possible to clamp on the standard center hole even when the outer diameter of a work piece is not centered.
Features a fully sealed structure that extends lubrication intervals and prevents coolant infiltration.
Suitable for higher or lower pressure gripping working.

后拉工件至參考定位上；
卡盤補償夾持；1補償夾持-2后拉-3夾緊
尾座底提供支撐零件所必需的力，卡盤把工件拉向中心，這樣工件不易彎曲，加工出來的軸同心度非常好。
Pull back the workpiece to the proper position
3 clamping process: 1st compensation gripping,
2nd pulling back, 3rd gripping tight
