Hydraulic compensation

Machining out-of-round workpieces

With the patented principle of hydraulic compensation, out-of-round components can be clamped and machined centrically without any shape constraints. This often saves machining steps. A major advantage over face clamping is the fact that at least one diameter range and one or both workpiece faces can be machined in one clamping operation

Problem	Properties	Workpieces
Asymmetrical workpiece Clamping force adjustable over a wide range High roundness requirement Large variety of workpieces Non-round clamping diameter Reduce machining operations Thin-walled components	Centric with hydraulic compensation Compensation clamping For high speed For non-round clamping ø For thin-walled parts High centring accuracy Number of jaws > 3 Pull down Several clamping levels	Brake disc Cam Cam adjustment Disc Electric motor housing Flange Gear wheel Hollow shaft Housing Milled part Pump housing Ring Ring - Cone ring Ring - Synchron ring Ring gear Shaft
