LA D DG LD LB 52 High Performance Live Centres M Series Type MZ with expansion compensation and pressure indication by graduated dial Centrepoint 60°, 75°, 90° Runout max. 0.008 mm max. 0.004 mm on request Application If the axial pressure must not exceed or fall below a defined value to clamp the component safely or to avoid workpiece deformation. When machining heavy workpieces prone to heat expansion. Type MZ without draw-off thread Type AMZ with draw-off thread for machines with tailstock sleeve without through bore (draw-off nut page 50) Type MZR with tailstock sleeve support ring and patented safety spigot (page 48) The tailstock sleeve support: makes the connection between tailstock sleeve and centre housing sturdier minimises the possibility of machining vibrations We recommend our tailstock sleeve support design when machining heavy workpieces, unbalanced and/or interrupted cuts high quality workpiece surface finishes are required Adjusting the clamping pressure The tailstock pressure required is adjusted on the graduated dial. When clamping the component, the central measuring pin is lifted in proportion to the travel of the centre spindle. The required clamping force is reached when measuring pin and scaling ring surface are level. Pressure too low Correct pressure Pressure too high Type MZ Type AMZ Type MZR DP DF LD ∝
