Features of the machine tool performance and structure
B2-2008 Eccentric Shaft Cylindrical Grinding Machine is a kind of machine tool exclusively used for grinding small size eccentric shaft parts.
- The machine offers reliable precision. Work head, equipped with special clamping apparatus, realizes fixing workpiece through hydraulic clamping with reliable precision.
- Equipped with sleeve type integrated bush hydrostatic/hydrodynamic bearing mainshafting, the grinding wheel spindle ensures high rotation precision and good rigidity.
- With plastic-filming guidewaybeing used, it ensures vibration absorbing and anti-friction as well as stability for low speed operation.
- Overall arrangement is reasonable with attractive appearance, concentrated and image operation handle. It offers simple safe operation.
- Screw pump is adopted for machine hydraulic driving which ensures smooth and steady operation with low noise.
