standardfor heavy workpieces

Precision live centers for heavy workpieces clamping with head angle 60° or 90° A special seal prevents the ingress of process liquid and dust particles. Possibility of implementing special designs according to customer specifications. Option to two accuracies - Normal and Extra. Possibility to use the live centers on grinders. The live centers are designed for heavy workpieces clamping on lathes. Very rigid construction and robust bearing of the rotatable part are characterized by very high durability. The advantage is the possibility of adjusting the clearance in the front radial bearing. The bearing spaces are filled with OL-J5 oil. The live centers of the category EXTRA precision are also used to clamp workpieces on grinders. To reduce deformations of the machine (tailstock, carriage, headstock) due to axial clamping forces, we supply the live centers with a head angle of 60 ° which is especially advantageous for machines loaded in the range of the permissible maximum. The live centers are provided with a taper shank Morse 4 ÷ 7 according to ČSN standard 22 0420 or METRIC (Me) shank according to ČSN 22 0410. The shanks comport to DIN 228 and ISO 296.
