Features
- The workpiece is clamped once and automatically grinds the inner hole and inner and outer end faces.
- The table longitudinal movement Z-axis and grinding wheel transverse feeding X-axis drive are controlled by Siemens AC servo system with high-precision ball screws.
- The grinding wheel holder adopts linear rolling guide.
- The working table adopts flat V-shaped plasticized guide rail.
- The headbox adopts high-precision roller bearings and AC frequency conversion speed control.
- Workpiece clamping adopts hydraulic film chuck, inclined wedge type sliding jaw chuck and end face clamping chuck.
- Dimension control adopts fixed-range grinding and measuring instrument measurement in processing, fixed-range grinding accuracy of 0.015mm, measuring instrument grinding accuracy of less than 0.01mm.
- The coolant filtration adopts magnetic plus paper precision filtration device.
- The grinding wheel axis adopts high-precision belt-driven mechanical grinding head or electric grinding head.
- The machine tool adopts a fully enclosed cover with a mist-absorbing device and reliable safety protection measures.
- All rails and ball screws of the machine tool are centralized and automatically lubricated by the lubrication station.
- The electric box and the machine tool are of integral structure, so users do not need to connect the machine tool and the electric box, which occupies a small area.
Applications
- CNC turret internal grinding machine is mainly used for grinding internal bore, internal concave endface, external endface, multi-stage bore, multi-stage endface, it is a multi-purpose production machine tool.
- The machine tool is suitable for military single piece small lot production and can also be used for mass production in automobile and other industries.
