“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 0-2ìm in short
time. This high precision “R” Zero holder
realizes invariant hole diameter, better
surface roughness, and longer tool life.
Even when runout of cutting tool at
chucking side is 1ìm , runout at the edge
is much larger when using conventional
collet chuck.
