Main Application and Features
- Headstock is driven by AC frequency-conversion motor, with the workpiece rotating-speed steplessly-adjustable.
- By slightly turning worktable at an angle, external-taper workpiece can be ground.
- Worktable is driven by hydraulic with speed steplessly-adjustable, cross-feed can be carried out with intermittent-feed or manual-feed.
- Guideways of worktable and wheelhead guide are both lubricated by pressure-oil.
- Wheelhead spindle is supported by sliding bearings, each composed by three segmental shoes.
- The machine can be equipped with optional center-grinding attachment for grinding center.
- The machine is easy to operate, suitable for batch production.
