Difference of difference of precision of machine tool treatment, precision of machine tool fixed position, machine tool machines workpiece to have knot knife mark, numerical value of compensating parameter of compensation of the pitch inside system of examination machine tool, backlash is true. Whether do electric machinery of examination machine tool and guide screw shaft coupling have shake a phenomenon. Whether does the axis that examines machine tool occurrence issue with dial gauge have backlash, measure backlash numerical value, can fill inside compensating parameter of backlash of machine tool system corresponding numerical value, close machine hind to be started afresh. Machine tool backlash can move those who rectify nut of machine tool guide screw to tighten force beforehand too in order to eliminate the backlash of the machine tool. Examination machine tool is set whether to become loose. Whether does electric machinery of examination machine tool have even line and servo even the line shake a phenomenon, whether does screen line join reliable, appear the phenomenon that lose a condition. Nut of guide screw of examination machine tool tightens force to carry silk on the head to whether become loose beforehand. 2, main shaft does not turn electric machinery of examination of ⑴ of 　 　 　 is rotational. ⑵ checks machine tool main shaft and electric machinery leather belt annulus connects axial section to whether become loose. ⑶ checks belt of tooth form of synchronism of machine tool main shaft to whether rupture. 3, the machine tool discharges bits implement do not turn, scrap cannot examination of ⑴ of 　 of eduction 　 　 discharges bits implement whether does entry point pile up scrap is too much, create a bit implement chain card is dead. Clear clean scrap, discharge bits every time not too much, can create a bit otherwise implement chain card is dead. ⑵ examination discharges bits implement electric machinery power supply is normal, whether can electric machinery turn normally. 4, the machine tool appears knife phenomenon, the machine tool does not grab a knife. Pressure of ⑴ examination pump is normal. District of gas of main shaft of ⑵ examination machine tool is expedite, have flat appearance, it is normal whether main shaft air cylinder moves up and down, loose, switch blocking a knife is normal. ⑶ examination air cylinder is flat, overhaul air cylinder piston and air cylinder weather strip. ⑷ examination machine tool catchs a knife child whether to open, adjust catch take the bolt below air cylinder to whether support to catch a knife child on upright, adjust catch a knife child on Duan Die reed. ⑸ examination machine tool catchs a knife child whether to wear away. 5, machine tool main shaft is loose not pressure of pump of examination of ⑴ of 　 of 　 of 　 of make sb the first aim of attack is normal. District of gas of main shaft of ⑵ examination machine tool is expedite, have flat appearance, it is normal whether main shaft air cylinder moves up and down, loose, switch blocking a knife is normal. ⑶ examination air cylinder is flat, overhaul air cylinder piston and air cylinder weather strip. ⑷ suggests the pump quality that the user uses is close friends, the gas water content that prevents pump is too big, cause air cylinder to rust motion does not loosen neatly not make sb the first aim of attack.
