Fully Automatic I.D. Centerless Stone Lapping Machine
Standard Application range :OD 35 - 130 mm x Length 6 - 45 mm x R dimension 3 - 10 mm
STK-200WTB-A
Application
1) Deep Groove Ball Bearing
2) Angular ball bearing
Main Features
- Centerless stone lapping machine for outer ring raceways of ball bearings
- Servomotor is directly connected to oscillating arm, enabling efficient changeover and condition changes. The stone head oscillating arm moves in smooth, sine-like curves, capable of indexing of precise oscillation angles, enabling high-precision stone lapping of gothic arc grooves.
- Outer diameter shoe centerless support system
Work piece: Ball bearing outer ring
