The version with the run – out tolerance of max . 0.0035 mm are, usually, employed in work on even grinding machines and, above all, in the grinding of heavy workpieces. The design features a small diameter of the center head which allows for an easy acces of the tool to workpiece. On centres with MORSE 2 – 6 taper the adjustability of the clearance in the front radial bearing is very advantageous. The MK 1 centre is of a different design and is intended for the clamping of very light workpieces. For the mentioned reason, the admissible load of the concerned centre is not specified. The live centre is provided with the shank with Morse taper according to DIN 228/ ISO296 without the clamping thread.
