1. The electrical equipment between CNC engraving machine milling machine shall meet the requirements of 10.1, 10.2, 10.3 10.4 of Article 10.
2. The linear coordinate moving parts shall be equipped with over safety device meet the requirements of 10.5.
1. The appearance, numerical control device mechanical device of Yiming CNC engraving milling machine shall be clean, the surface shall be free obvious indentation, scratch other phenomena. The coating surface shall be smooth, smooth even without wrinkle, cracking, peeling other defects, metal parts shall be free corrosion mechanical damage.
All kinds of indicator lights, switches, buttons, frequency converters, programmable programs, controllers other components should be flexible reliable.
3. The lubricating device shall be easy to adjust, flexible, well lubricated reliable. The functional words graphic symbols should be clear, the ending should be correct, the indicator should be correct.
The test method was as follows
1. Large CNC engraving milling machine should work normally according to four specifications.
2. Under the condition of air running, the air running test is carried out for the spindle head of CNC engraving machine low speed, medium speed to high speed. The speed of each gear is less than 2 minutes, the longest time is less than 2 hours. The temperature of the spindle is stable the bearing temperature is more than 65 ℃.
3. For the parts moving in the online coordinate system, the speed of 50 mm / min, 800 mm / min, 3000 mm / min, 6000-8000 mm / sub high speed should be stable, flexible, reliable, reliable free of vibration crawling under the condition of aerial operation.
（4） CNC engraving milling machine should work normally according to the requirements of four specifications.
5. Under the condition of air running, the air running test is carried out for the spindle head of CNC engraving machine low speed, medium speed to high speed. The speed of each gear is less than 2 minutes, the longest time is less than 2 hours. The temperature of the spindle is stable the bearing temperature is more than 65 ℃.
6. For the parts moving in the online coordinate system, the speed of 50mm / min, 800mm / min, 3000mm / min, 6000-8000mm / min, 6000-8000mm / min should be stable, flexible, reliable free of vibration crawling.
7. In the NC program design instruction F, the continuous simulation test is carried out for 72 hours under the conditions of 5.3, 5.4 5.5. The NC function working ability are stable reliable, whether the e.s.tm.g function is normal.
The mechanical geometric accuracy of engraving milling machine is measured by the level of measuring instrument (plate box).
8. CNC engraving milling machine positioning accuracy, repeat positioning accuracy, reverse deviation, using special laser interferometer, special step block type, other detection tools.
