Fault phenomenon: XH755 horizontal machining center, the Y-axis positive (ten) direction error increases when working, the processed parts are scrapped, and the error range can be found from 0.01 to 0.50mm during measurement and inspection. Analysis and repair process: According

Failure phenomenon: A machining center equipped with the FANUC-0MC system has been modified by CNC. After a period of use, a tool change failure occurs. When the tool is inserted into the spindle hole, there is no alarm message on

Swiss S-45 CNC grinder, SINUMERIK-3 CNC system, alarms 123, 122 and 222 appear irregularly when working. The alarm sometimes appears when the Z axis moves fast or just starts moving, and sometimes it appears when the grinding wheel is corrected.Analysis

Failure phenomenon: a CNC machine tool with a CNC system cannot process the program after editing save. Analysis and processing process: After many tests on site, it was found that the machine tool can be operated manually, handwheel, -8+, but

Failure phenomenon: an industrial control machine as the main control, using Spain (the system as the CNC part Copy key milling machine, when a part is processed and a new processing program is replaced at a time, the machine suddenly

cause of issue: The communication between the encoder and the servo module is incorrect, and the data cannot be transmitted normally. Recovery method: There are three links involved in the alarm: encoder, cable, and servo module. Check the cable interface

Trouble phenomenon: A gantry machining center equipped with FANUC 15MA CNC system, after the start is completed and enters the operable state, as soon as the X axis moves, high frequency oscillation occurs, the motor screams, and the system does

Trouble phenomenon: A CNC machine tool equipped with FANUC OMC, model XH754, when the rotary table is indexed, it will move obviously and fall loudly. Analysis and processing process: when the turntable is indexed, the shift is obvious when it

Trouble phenomenon: A CNC machine with model XH754 supporting FANUC OMC, the turntable is not allowed to return to zero, and the worktable is skewed after returning to zero. Analysis and treatment process: This kind of failure is generally caused

A CNC lathe uses the FANUC 0 TB system. The fault phenomenon is: when the tool change command is input, the turret tool change rotates continuously without any alarm. The rotation command has the following functions: ① can judge the
