China Double Disc Surface Grinding – YUHUAN Double Disc Grinding machine YHDM580D – Maiouke

Characteristic

1. C-type grinding and continuous grinding (optional swing grinding, double planetary grinding), to achieve high precision and efficient grinding;
2. Large window at the backside to change grinding wheel, Fixed feeding carrier, convenient for supporting automation.
3. Siemens NUMERICAL control system (optional Central China system), simple operation, powerful and perfect.
4. The upper box, the lower box and the feeding carrier are respectively vertically connected and fixed to ensure the smooth operation of machine.
5. Adjust the Angle of upper and lower box by three-point adjustment mode, so as to adjust the parallelism and Angle of upper and lower grinding head, more convenient operation, stable and reliable.
6. Disc type servo dressing mechanism, with multiple groups of oilstones participating at the same time, high dressing efficiency.
7. Feeding shaft is equipped with high precision grating ruler to ensure micron feeding accuracy.
8. High rigidity and large torque electric spindle, smooth operation, eliminate vibration caused by transmission chain, improve grinding efficiency and accuracy.
9. The spindle center delivers water to improve grinding efficiency.

Processing type

Grinding Structure

Machinery Precision and Stability

1. The machine adopts box structure with vertical spindle for upper & lower grinding.

2. The spindle structure is a combination of double cylindrical roller bearing and double direction angular contact thrust ball bearing, ensuring the stability & rigidity of the grinding heads.

3. The main motor transmits the torque to the spindle through triangular belt-wheel. And unloading structure is adopted between triangular belt-wheel and splines to avoid bending load on the spindle.

4. Grinding head feeding cotrolled by high-precision ball screw unit, with feeding precision up to 0.001mm, which secures the stability of grinding process.

Installation of Grinding Wheel

Integrated crane is equipped for unloading/loading of the abrasive wheels. Unique swing-out structure for the feeding carrier provides outstanding space for tool changes. Portable wheel changing aid for rapid & easy transportation of the tools, reducing labor intensity and improving work efficiency.
