1. Matters need attention
Machine tools used for high precision machining 1.1, machine tool must be installed in temperature is 20 ℃ degree is obtai ℃, relative humidity not more than 705% of the constant temperature indoor, and should avoid direct sunlight and local heat source of radiation. Room temperature change should not be more than 0.5 ℃ / 4 hours.
1.2 machine should be with shockproof foundation ditch.
1.3 access of the machine tool should be compressed air is filtered air drying, the compressed air pressure should be less than 10 ℃ temperature dew point.
1.4 was processing components to transport into the constant greenhouse, depending on the size of the parts must be isothermal two to three hours, the measuring tool should be the isothermal in advance, and then to processing and measurement.
1.5 workpiece must not be more than the maximum weight load bearing.
1.6 was processing components shall not directly and working mesa contact, to prevent damage working mesa.
1.7 the machine spindle axis with the thermal stability of the device (thermal compensation system). This is an electronic system to reduce because caused by the machine's operation cold and heat caused by temperature difference grinding head box the thermal displacement effect, ensure the machining accuracy. The thermal stability of the factory has been adjusted well when device, users do not change. When use, this device may not be cut off the power supply. Therefore on the electric alone with the power switch, even to the night when not working this power supply and shall not be cut off, if machine tool for a long time and cut off the circuit is not working power, machine tool already cooling to room temperature, again before work, in advance of the device should be on the power, through to the time more than 4 hours, machine in a hot state, and then you can carry on the processing.
1.8 in every day on the machine and suddenly loses power after the restart, the axis shall conduct a back to zero.
2. Common failure elimination method
Serial number phenomenon reason elimination method
The worm gear and worm jitter 2.1 large clearance adjustment worm wheel clearance is less than 0.01 mm
2.2 c shaft axis large clearance s switch to the c the shaft speed more than 60 turn to adjust the ball spline clearance
2.3 grinding head bearing damaged oil mist lubrication is too full to the oil content is gas
2.4 grinding head motor not turn brush contact undesirable change brush
