47 Lathe centres Hoffmann Group Maximum concentricity. Extremely free-ru n n ing. Point is not ground until it is mounted Shaft seal prevents ingress of dirt and coolant. Bearing arrangement for high axial forces. High-quality bearing accuracy class, thus the spindle bearings have a radial run-out of 0.001 nm. Top quality "Made in Germany". Precise and durable. Wide range for all applications. Attractive design. Tool completely hardened, internally and externally ground in a single clamping. Maintenance-free, lubricated for life. Punch axis of through-hardened steel. Revolving lathe centres Punch axis of through-hardened steel mounted on shank bearings. Live centre through hardened, multiple regrinding possible. Precision roller bearings for high concentricity. Maintenance-free due to lifetime lubrication. Special seal prevents ingress of dirt and coolant. Complete tool hardened and ground. 320657- Point angle 60°. 32 0658 - With extended centre, point angle 60° / 30°. Application: For all types of lathe, equally suitable for roughing and finish turning. 32 0658 - Extended point allows unobstructed access for the turning tool on the end face of the component. Particularly suitable for copy turning. 32 0659 - Flexible application thanks to exchangeable inserts. For general use on turrets and counter-spindles on CNC machines.
