Description

The chucks are intended for clamping of piece blanks over their external surfaces on multi-spindle automatic lathes with P accuracy class.
Design of chucks provides for jaw inserts compatibility, that allows to increase productivity and accuracy to a great extent when workpieces machining on automatic machines.
Chucks secure inner space sealing from entry of fine chip and bleeding of lubricate, increasing of lifetime, jaws centering particular accuracy.
