Hoffmann Group 47 R Hm Revolving lathe centres -with pressure indicator The adjusting pressure (clamping force) is directly readable on the manometer sight glass in daN. The live centre, which is supported byadisc-spring pack, has a long spring travel. Short sturdy design with active longitudinal axis. Live centre through hardened and finish ground. Maximum accuracy due to precision roller bearings. With special seal against dirt and coolant ingress, maintenance-free due to lifetime lubrication. 321750- Point angle 60°. 321770 - With extended centre, point angle 60° / 30°. Application: Whenever the clamping force has to be kept within certain limits.either to prevent deformation of the component or to ensure secure clamping with sufficient pressure. As a tailstock centre in conjunction with hydro-mechanical face drivers No. 327450 - 327540 because the drive teeth have to dig into the component. For components that expand significantly due to high machining heat. For clamping long slender components to prevent lateral displacement. For clamping heavy components where a controlled clamping force is required. Pressure indicated by pressure gauge. 321750 with 60’point.
