constant face driver / Morse taper shank
constant, Morse taper shank
The 684-90 CoE was developed according to the modular system. It consists with mechanic pressure compensation. It provides a uniform clamping force also on uneven faces of workpieces. It has also a spring loaded center. It provides a longitudinal workpiece stop on the front side workpiece. It has a maximum weight of 100 kg.
The 684-90 CoE has its clamping circuit of Ø 8-80 mm. It is widely applied for rational turning of workpieces on their entire length without reclamping with high precision. The device has compensating driving plates with radial freedom of movement.
