CNC wood lathes are classified according to the location of the fault
Which types of CNC woodworking lathes are classified according to the location of the fault?
1 host failure
The mainframe of CNC woodworking machine tools usually refers to the mechanical, lubrication, cooling, chip evacuation, hydraulic, pneumatic and protective components of CNC machine tools. Common faults on the host are:
1) Mechanical transmission failure caused by improper installation, testing, improper operation and other reasons;
2) Failure caused by interference of moving parts such as guide rails and spindles, excessive friction, etc.;
3) Failure due to damage to mechanical parts, poor connection, etc.
The main faults of CNC wood lathe main engine are transmission noise, poor machining accuracy, large running resistance, mechanical parts stop operation, mechanical parts damage and so on. Poor lubrication, hydraulic and pneumatic system piping blockage and poor sealing are the main causes of host failure. The regular maintenance, maintenance, control and eradication of the "three-leakage" phenomenon of CNC woodworking machine tools is an important measure to reduce the partial failure of the main engine.
2 electrical control system failure
From the type of electrical components used, according to the usual habits, electrical control system failures are generally divided into two categories: weak electrical faults and high electrical faults.
The weak current part refers to the control part of the control system mainly composed of electronic components and integrated circuits. The weak parts of CNC woodworking machines include CNC, PLC, CRT, servo drive units, input and output units, and so on.
Weak current faults are divided between hardware and software faults. A hardware failure refers to a failure of an integrated circuit chip, a discrete electronic component, a connector, and an external connection component of each of the above components. Software refers to faults such as action errors and data loss that occur under normal hardware conditions. Commonly, there are errors in machining programs, changes or loss of system programs and parameters, and computer errors.
The strong electricity part refers to the main circuit in the control system or the relays, switches, fuses, power transformers, motors, electromagnets, travel switches and other electrical components in the high-voltage, high-power circuits and their control circuits. Although this part of the fault is more convenient for maintenance and diagnosis, but because it is in high-voltage, high-current working state, the probability of failure is higher than the weak part, which must be paid attention to by maintenance personnel.
