R Hm Revolving lathe centre -with pressure indicator Version The adjusting pressure (clamping force) is directly readable on the manometer sight glass in daN. The live centre, which is supported by a disc-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. 32 1750- Point angle 60°. 32 1770- 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. 32 7450 - 32 7540 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. 321750 with 60°point.

Extended point for unobstructed turning tool access. R Hm Revolving bull-nosed centre Version Centre angle 75°. The front of the centre is bull-nosed. Particularly sturdy design with oversize bearings. The bearings have a special lubricant and require no maintenance. The centring taper and tapered arbor are made of high quality material, through hardened and finish ground. Application For machining hollow parts, tubes etc. Particularly suitable for heavy machining where at the same time high accuracy is required. HOLEX Solid lathe centres Standard DIN 806 Version Point angle 60°, surfaces ground. 32 3400- Full point of tool steel, through hardened. 32 3600- Full point with deep inserted carbide centre. 32 3600/3800- The carbide tipped lathe centres are marked with a groove to indicate maximum regrinding allowance. 32 3800- Half point with deep inserted carbide centre. This offers particularly good access for the turning tool to the end face of the component.
