SR-80

for outer diameter of large sized spherical rollers

Standard Machining range :
OD 40 - 80 x L 40 - 115 mm x Raceway Curvature 200 - 430 mm

Main Features

Capable of stone lapping on outer diameter of large-sized self-aligning spherical rollers
Single-piece infeed-type machine with limited tooling numbers for easy changeover
Designed with workability in mind, changeover can be performed without moving the in/out chutes, making it easy to secure a work space
Servomotors used in oscillation unit enable precise adjustments of the oscillation angle
