The machine uses mainly the wheel periphery for grinding the surface which has higher requirement for parallelism and surface roughness. The machine can be used for high precision surface grinding, as well as for grinding external or internal taper. So, the machine is suitable for grinding such as precision bearing race, index plate and precision measuring instrument in the bearing factory, tool and measuring instrument factory and precision instrument manufacturer.

The machine adopts the moving-column principle, in this way, the table does rotating movement, longitudinal feed is derived from the movement of the column and the wheel head can only move up and down on the column for vertical feed.
The table is driven to rotate by a motor with frequency convert and through speed reduction by the triangular belt. The lead screw is driven by a servo motor through speed reduction by the triangular belt to make the column move longitudinally.
The wheel head moves up and down by a servo motor through speed reduction of a pair of gears to drive a lead screw to elevate the wheel head. The CNC system adopts SIEMENS system whose feed sensibility is 0.001 mm.
