- Grinding parameter optimization
According to the grinding characteristics of grinding wheel, reasonably improve the grinding parameters. Comparison of grinding efficiency before and after optimization of grinding parameters in our plant.
- Optimization of grinding wheel dressing parameters
The grinding wheel dressing parameters are optimized to increase the single dressing amount, which is convenient to remove the residual grinding debris in the air hole and maintain the self sharpness of gravel. Due to the reduction of dressing times, the grinding time is also greatly reduced.
- Optimization of grinding wheel diameter parameters
In order to prevent grinding burn, the grinding wheel diameter parameters are optimized, that is, the requirements are:
Where: CB is grinding tempering coefficient; DS is the outer diameter of the grinding wheel; AP is the feed depth; Vs is the linear speed of grinding wheel rotation.
- Monitor the power of forming gear grinding machine
When grinding the tooth surface, the power of the forming gear grinding machine shall be within a certain range. In order to prevent grinding burns, the power during grinding shall generally not exceed 60% of the rated power of the machine tool, that is, the requirements:
Of which: η Is the transmission efficiency from the main motor to the main shaft of the forming gear grinding machine, taken as 0.95; PC is 60% of the rated power of the main motor; F is the feed speed of grinding wheel.
After optimizing the grinding parameters, monitoring the power of the forming gear grinding machine can avoid the high grinding power caused by the excessive setting of grinding parameters, resulting in tooth surface burns. The spindle power monitoring interface is shown in the figure.
