Plane drill is a kind of machine tool with high technology, which integrates mechanical and electrical instruments. After users buy a plane drill, whether it can start up correctly and safely is a key step. Whether this step is correct or not largely determines whether the plane drill can play a normal economic efficiency and its own service life. The starting and debugging of the plane drill should be carried out according to the following steps: < br style = "list style type: none; " />1. Appearance inspection before power on, plane drill electrical inspection, open the electric control box of the machine tool, check whether the relay, contactor, fuse, servo motor speed, control unit socket, spindle motor speed control unit socket are loose, if loose, return to normal state, the connector with locking mechanism must be locked, and the machine tool with transfer box must be checked If the socket and wiring are loose, those with locking mechanism must be locked. For equipment with secondary wiring, such as power transformer, confirm the consistency of phase sequence of secondary wiring. The correct phase sequence should be ensured. At this time, the power supply voltage should be measured and recorded. In MDI test, the actual speed of the spindle is measured, the locking switch of the plane drill is put on the on position, and the manual data input command is used to conduct the spindle random gear change and speed change test. The actual speed of the spindle is measured, and the displayed value of the spindle speed is observed. The adjustment error should be limited to 5%. The purpose of tool selection test of turret or cutterhead is to check the correctness of tool holder or forward, reverse and positioning accuracy. In the edit function test, the state selection switch is placed in the edit position, and a simple program is compiled by ourselves, which includes as many function instructions and auxiliary function instructions as possible. The movement size is limited to the specified stroke of the plane drill, and the program is added, deleted and modified at the same time. 3. Turn on the total voltage of the machine tool, turn on the main power supply of the machine tool, check whether the rotation direction of the CNC electric box, the cooling fan of the spindle motor, the cooling fan of the electrical box of the machine tool is correct, the oil mark indication at the lubrication, hydraulic pressure, etc. and whether the lamp of the machine tool is normal, if there is any abnormality, the power supply shall be cut off immediately for maintenance, and if there is no abnormality, it can be continued. Measure the voltage of each part of strong current, especially the primary voltage of power transformer for CNC and servo unit, and make records. Observe whether there is oil leakage, especially the hydraulic cylinder and solenoid valve at the rotating tower, clamping, spindle shifting and chuck clamping. In case of oil leakage, the power supply shall be cut off immediately for repair or replacement. < br style = "list style type: none;" / > 4. When the CNC electric box is powered on, press the CNC power on button to turn on the CNC power supply, and observe the CRT display until the normal screen appears. If the alarm display appears, the fault should be found and eliminated. At this time, the power transmission should be checked again. Turn on the CNC power supply and measure the voltage at all levels according to the position of the test terminal given in the relevant data. If there is any deviation, it should be adjusted to the given value and recorded. Put the status switch in an appropriate position. For example, the FANUC System in Japan should be placed in MDI state and select to the parameter page. Check the parameters one by one, and these parameters should be consistent with the random parameter table. If it is found that the value of each parameter is not consistent with the actual value, if it is found that it is not consistent with the actual value, it should be corrected at any time.
