Things you need to pay attention to when buying a CNC lathe

CNC machine tools are technology-intensive equipment integrating mechatronics. Whether the machine tool can operate reliably for a long time depends to a large extent on its use and maintenance.

1. Precautions when using CNC machine tools: The entire processing process of CNC machine tools is completed in accordance with digital procedures by a CNC system composed of a large number of electronic components. If the workpiece is scrapped or a safety accident occurs due to the failure of the CNC system or execution components during processing, There is generally nothing the operator can do. Therefore, the requirements for the stability and reliability of CNC machine tools are more important. For this reason, the following issues should be paid attention to when using CNC machine tools.

(1) Usage environment of CNC machine tools: Generally speaking, CNC machine tools have no special requirements for the use environment and can be placed in the production workshop like ordinary machine tools. However, direct sunlight and other thermal radiation should be avoided, and places that are too humid or dusty should be avoided, especially places with corrosive gases. Corrosive gases are most likely to cause corrosion and deterioration of electronic components or cause poor contact. Or it may cause components to short-circuit, affecting the normal operation of the machine tool. Stay away from equipment with large vibrations, such as punch machines, forging equipment, etc. For high CNC machine tools, anti-vibration measures (such as anti-vibration trenches, etc.) should also be taken. For high-precision and expensive CNC machine tools, it is ideal to use them in an air-conditioned environment.

(2) Power supply requirements: CNC machine tools adopt dedicated power supply lines (separate one line from the low-voltage power distribution room for use by CNC machine tools) or add a voltage stabilizing device, which can reduce the impact of power supply quality on machine tools and electrical interference.

(3) CNC machine tools should have operating procedures: Operating procedures are one of the important measures to ensure the safe operation of CNC machine tools. Operators must operate according to the operating procedures. When a machine tool fails, the operator should pay attention to retaining the scene and truthfully explain the situation before and after the failure to the maintenance personnel. This will facilitate analysis and diagnosis of the cause of the failure, troubleshooting in a timely manner, and reduce downtime.

(4) CNC machine tools should not be stored for a long time: after purchasing CNC machine tools, you must make full use of them and try to increase the utilization rate of the machine tools, especially in the first year of use, so that the weak links that are prone to failure are exposed as soon as possible. , the hidden dangers of faults should be eliminated as much as possible within the warranty period. If the factory has no production tasks and the CNC machine tool is not used for a long time, it should be powered on regularly. It can be powered on 1 to 2 times a week and run dry for about 1 hour each time to use the heat generated by the machine tool itself to reduce the humidity inside the machine. This prevents electronic components from getting damp, and at the same time, it can detect in time whether a battery alarm occurs to prevent the loss of system software and parameters.

(5) Work with a certificate: Operators must not only have qualification certificates, but also have to receive special operation training based on the machine tool used by technicians before taking up the job. They must be familiar with the instructions and the structure, performance, and characteristics of the machine tool, and master the instruments and switches on the operating panel. , the functions and instructions of the knobs and buttons, blind operation and misuse are strictly prohibited.

(6) Compressed air meets standards: The pressure of compressed air required by CNC machine tools should meet standards and be kept clean. It is strictly forbidden to use ungalvanized iron pipes for pipelines to prevent rust from clogging the filter. It is necessary to regularly check and maintain the gas and liquid separators to prevent moisture from entering the gas line. Install a gas and liquid separation and filtering device outside the machine tool's air pressure system to increase protection links.

(7) Correct selection of cutting tools: Correct selection of high-quality cutting tools can not only give full play to the processing efficiency of machine tools, but also avoid unnecessary failures. The specifications and dimensions of the tool should meet the technical requirements, otherwise the tool change operation will not proceed smoothly.

(8) Detect each coordinate: Before processing the workpiece, each coordinate must be detected, the program reviewed, and the processing program simulated and tested normally before processing.

(9) Prevent collisions: Before the equipment returns to the "machine zero point", "working zero point...'control zero point" operation, it must be determined that the movement direction of each coordinate axis is free of obstacles to prevent collisions.

(10) Do not dismantle key components at will. The CNC machine tool has a simplified mechanical structure, reliable sealing, and increasingly perfect self-diagnosis functions. During daily maintenance, except for cleaning the exterior and specified lubrication parts, other parts must not be disassembled and cleaned. for key components. Devices such as grating rulers of CNC machine tools must not be collided or dismantled at will.

(11) Do not change parameters at will: The safe storage of various parameters and basic setting programs of CNC machine tools directly affects the normal operation and performance of the machine tool. Operators are not allowed to modify them at will. If improper operation causes a malfunction, the situation should be explained to the maintenance personnel in time. In order to find fault clues and deal with them.
