Precautions and maintenance items during CNC machining of parts

The board handling workshop should make efforts to process the board handling parts. When the parts are too high, different lengths of knives should be used for layered cutting. After cutting with the knife, a small amount of leftover material should be discarded, and a flat surface should be machined with a flat bottom knife. Use less ball end knives and do not reduce the machining force; Even if there is a slope and it is flat, it still needs to be machined with a slope cutter.

Clamping one workpiece at a time should be able to process all the appearances of the workpiece; When determining the placement position of the workpiece on the workbench, it is necessary to discuss the coordinated processing of each workstation, the impact of tool length and stiffness on processing quality, and the use of fixtures in controlled processing should be assembled from universal components as much as possible, while minimizing the consumption of preparation cycles.

When programming on the medium and thick plate rolling mill, some basic rules should be followed, including "first face, then hole", "first coarse, then fine", etc. According to the time sequence of tool matching, the same tool should be stopped from being reused to reduce the degree and intensity of tool replacement.

For hole systems with high coaxiality requirements, the hole system should be machined after one positioning, and then the hole system at other coordinate positions should be machined. This can eliminate the defect of repeated positioning, promote the coaxiality of hole systems, and the tool point and tool change point are determined. Once decided, do not change them.

Carry out maintenance work for CNC machining

Everyone knows that everything needs to be maintained, which can make it difficult to use for a long time. As is well known, the core of CNC machining is also the same. The correct use and maintenance of CNC equipment is one of the main factors for the correct application of CNC equipment. Only with reasonable use and application can abnormal damage to CNC lathes be avoided, and common faults in high-precision CNC machining be prevented. Daily maintenance and upkeep should be carried out to maintain the stable process condition of mechanical equipment, slow down the deterioration process, timely handle and eliminate common faults and safety hazards, and always ensure safe operation.

1. In order to improve the service life of CNC equipment, the application environment generally requires protection against direct sunlight and other radiation heat, as well as prevention of excessive humidity and cold, excessive smoke or corrosive steam. High precision CNC equipment should avoid mechanical equipment with high vibration, such as high-speed punching machines, casting machines, etc.

2. Excellent switch mode power supply guarantee: In order to better prevent frequency changes (± 10% or more) and possible instantaneous electromagnetic interference hazards of switch mode power supply, CNC equipment for processing and manufacturing generally adopts a dedicated transportation power supply system (such as from the distribution system), and the electrical room is equipped with independent channels for CNC machine tool applications) or adds voltage stabilizing tube equipment. CNC spinning can reduce interference and impact on the quality of the power supply system. It is recommended to use a CNC machining process solution for tool stamping.
