PAT. Having run out problems at the tool tip? NT’s patented R-Zero collet chucks offer the solution to your T.I.R problems! With “R-Zero” function HDZ High precision Slim design Runout accuracy of the cutting edge can be adjusted as closely as to Zero with “R” Zero holder. Adjustment wrench 4 Screws FDC-AA grade collet is recommended. Rotor ring Conventional Collet Holder “R ” ZERO Holder Even when runout of cutting tool at chucking side is 1μm , runout at the edge is much larger when using conventional collet chuck. “R”-Zero Setter SPZ-2 Easy to measure runout accuracy ●Rotary holder support Any tool interface can be prepared. (BT, HSK, UTS, SK etc.) ●Holder pull-in device Enables tool change by pulling in (wih 4-8kN) and fixing the tool holder. “R” Zero holder is a collet chuck with a runout adjustment function to reduce the misalignment of the cutting edge. The accuracy can be adjusted to 0-2μm in short time. This high precision “R” Zero holder realizes invariant hole diameter, better surface roughness, and longer tool life. Mueasement range 0-460mm in length
