Machine Main Structure

  • They are cast of high grade FC-30 iron, melted by advanced induction furnace, then cast in resin cores.In order to ensure stability and rigidity, they are heat-treated with normalizing procedure prior to machining. This mechanical structure major consider load, speed, accuracy and stability.In order to achieve above conditions, the structure was designed with a more stable triangle rib of principle, it can be increased rigidity against bending and torsional rigidity.

C Type Machine Structure

  • This C-type machine structure design was to solve X axis straightness problem that influenced from gravity also alleviate column deformation by stress, it totally improve X and Z axes straightness, reduce Z axis loaded and guide way straightness deviation.

Slant Guide Way

  • X axis adopt slant guide way designing it can be eliminated gap through gravity and increase machine rigidity, improve coolant draining speed and avoid coolant temperature affect machine accuracy.

Work Table Horizontal Adjustment Structure

  • It’s capable of adjusting workpiece cylindricity deviation. Work table adopts two ramps fit each other and rotation principle, become an adjustable leveling structure, to compenpensate X and Z axes perpendicularity deviation and Z axis guide way straightness deviation, more over to enhance machine structure and workpiece geomatric accuracy.

Hydrostatic Table

  • Germany made hydrostatic rotary table with very good axial and radial run out.

Angular Axis

  • Grinding wheel head spindle can be manually or automatically(opt.) rotated ±30° to grind the taper of workpiece.
