Configurations
3MZ258A Auto roller OD grinding machine for cylindrical roller, taper roller bearing, spherical roller and needle roller
AJS778A Auto roller OD superfinishing machine for cylindrical roller, taper roller bearing, spherical roller and needle roller
Features and Benefits
1. The grinding speed is set on the display screen. The OD grinding machine provides Single-point diamond radius dressing or diamond roller radius dressing for roller OD, which can dress the radius contour with crowning amount 0~40 micron adjustable.
2. Constant speed grinding, with clamping electric current at 0.1~2.0A adjustable, with "High-Low" switch.
3. The superfinishing machine have four oscillation-heads at four stations can superfinishing rough and fine one time separately, or separately superfinishing rough and fine. The oilstone pressure, oscillation frequency and workpiece rotational speed can be set on the display screen.
4. Full enclosure with three sliding doors, electrical cabinet has an IP54 protection level sealed structure and is equipped with a constant-temperature air conditioner.
5. The modular kit system enables customer-specific designs.
