When replacing the stone engraving machine tool most appropriate:
After serious stone engraving machine tool wear, cutting force can be increased to three times normal. The cutting force has a great influence on the life of the electrode axis, and the life force of the spindle motor is inversely proportional to the third power relationship. For example, in the case of the cutting force is increased three times, processing one minute, the equivalent use of the spindle 27 minutes under normal conditions. Stone carving knives after severe wear visible not only affects the processing of the sample results, but also affect the life of the spindle.
So what's the time to replace the stone carving tool is the best? We should be in the tool life tool change time limit at 2/3 of the. For example, a serious tool wear in 60 minutes, the next machining, tool change should begin in 40 minutes, and develop a regular tool changing habits. This will not only ensure quality but also improve the processing spindle life.
