Classification of CNC Machine Tool Faults in Precision Parts Processing
The components of CNC machine tools that fail in precision parts processing are classified as (1) main machine failures Common main machine failures include: mechanical transmission failures caused by improper mechanical installation, commissioning and operation, or failures caused by excessive friction of guide rail movement. The failure of hydraulic, lubricating and pneumatic systems is mainly caused by pipeline blockage and poor sealing. (2) Electrical fault Electrical fault is divided into weak current fault and strong current fault. The weak current part mainly refers to CNC devices, PLC controllers, CRT displays, servo units, input and output devices and other electronic circuits, which can be divided into hardware failures and software failures.
Precision parts processing
Hardware failure in precision parts processing mainly refers to the failure of integrated circuit chips, discrete components, connectors and external connection components on the printed circuit boards of the above devices. Common software failures include: error in processing program, change or loss of system program and parameters, error in computer operation, etc. The strong current part refers to circuit breakers, contactors, relays, switches, fuses, power transformers, motors, electromagnets, travel switches and other electrical components and the circuits they compose. The failures in this part are very common and must be paid enough attention.
