Processing Methods

Equipment Highlights

1, X-axis, c-axis, z-axis, b-axis can achieve two-axis to four-axis linkage, can achieve the workpiece's internal and external contour, Cone, end face, etc. .  

2. Equipped with three synchronous mounted electric spindles (SP1, SP2, SP3) , the grinding head covers a wide range of rotational speed and stiffness, effectively improve the processing efficiency and technicality.

3. B-axis can realize high precision, arbitrary angle positioning, repetitive positioning accuracy ± 2.5′ , can realize arbitrary cone machining, avoid the deficiency of machining cone and reduce the wheel wear.

4. The X and c axes are hydrostatic, the friction coefficient of hydrostatic guide is only about 0.005, and that of linear guide is 0.15. The friction coefficient of hydrostatic guide is only about 0.005.

5, X Axis uses direct-drive motor, no reverse clearance, can completely solve the problems such as over-quadrant bulge.

6. SP1, SP2, SP3 are equipped with on-line dynamic balance and AE device, which can effectively solve the grinding vibration and abnormal collision caused by the unbalance of grinding wheel, and improve the grinding surface quality and the safety of the machine tool.

7, B shaft equipped with clamping system, rated locking torque up to 2900n. M, to ensure that the wheel at a fixed angle grinding rigidity.

8. On-line automatic measurement function, it can realize automatic on-line measurement and automatic tool setting.

9, equipped with diamond roller dressing and diamond pen dressing two ways, can achieve grinding wheel plane and curved surface dressing.

10.Man-machine interaction software with 3D simulation, full-function CNC package, it includes the functions of face grinding, inner circle grinding, outer circle grinding, wheel dressing, on-line measurement and calibration, etc. .
