Centerless Grinding Machine
A Center Grinding Machine precisely grinds the outer daimeter of cylindrical material and is used variously across all industrial sectors including automobile, electricity, electronics and appliances. This machine does not support the center of processed goods and develops the grinding process which is different from a cylindrical grinder.
DC-18 CENTERLESS GRINDING MACHINE
Spindle and Bearing
- Raises axial stiffness by supporting the grinding wheel with workhead and 3 bearings at shaft ends.
- Use of a hydraulic dynamic bearing to enhance high bearing stiffness and vibration reduction effect, showing excellence in powerful grinding and precision grinding.
Feeding device and horizontal spin device
- Lower feeding device and upper feeding device performing respectively the feeding of the grinding stand and regulating wheel.
- Precise feed adjustment is enabled by cross feed of a feeding device, a minute feeding handle and the back flash adjustment device of a feeding screw.
- The lower slide sideway maintains long-term precision by being precisely produced by multiple profiles.
- A regulating wheel spin device capable of rotating up to ±5 degrees horizontally is used to adjust a level of parallel on the regulating wheel axis and the taper angle (adjustment during the operation also possible)
Inversion device of a regulating wheel
- Enables the regulating wheel to rotate up to ±5 degrees, which broadens ranges of the speed at which work pieces pass.
- Very useful for setting the reference position when working during the stoppage.
