Planetary motion diameter range: 0~12mm
Maximum speed of planetary motion: 0 ~ 60r/min
X1/X2, Z1/Z2 axis resolution: 0.001mm
Machine weight: about 5000kg
Overall dimension (L×W×H): 3020 × 1405 × 2280mm
Machine accuracy:
1. Spindle rotation accuracy:(1) radial runout of inner hole: 0.003mm;(2) axial runout of shaft end: 0.002mm;
2. Repetitive positioning accuracy of fixture clamping: 0.03mm;
Typical parts machining accuracy:
1. Measure the excircle runout of the workpiece with the center hole (after grinding the excircle):≤ 0.002mm;
2. Surface roughness: ≤ Ra0.8μm;
3. Center hole cone angle: 60 ° 0 -5 ′;
Main structural features:
1. The machine tool adopts double spindle layout and horizontal 45 ° inclined bed structure design.
2. The clamping device can realize automatic centering function driven by servo motor, which is not affected by the diameter of the workpiece and is convenient for multi-variety production.
3. Using adaptive processing technology, there is no need for cumbersome positioning and tool setting, and the center hole of the workpiece can be automatically ground by the tool only by placing the workpiece within the specified range.
4. Innovative center hole grinder design, so that it has the dual function of grinding and grinding. To achieve a machine tool processing requirements of different center holes.
5. Grinding adopts electric spindle drive, which can realize high-speed grinding. The grinding is driven by a servo motor through a toothed belt, which can achieve low-speed grinding.
