Do you know some basic knowledge of machining? Such as commonly used equipment, processing procedures, production types and precautions? Here, Changzhou Machining would like to briefly introduce some knowledge so that you can have a deeper understanding of large-scale machining. 1. General machining equipment    including cnc milling machine, cnc forming grinder, cnc lathe, electric discharge machine, grinder, cylindrical grinder, internal grinder, precision lathe and other equipment, these equipment can do turning, milling, planing, grinding, etc. Process. The machining accuracy can reach 2um.  2. Processing and manufacturing procedures   The production process includes raw material transportation, production preparation, workpiece manufacturing, parts processing and heat treatment, parts assembly and debugging. Through mechanical processing, the shape, size and performance of the raw materials can be changed to meet the requirements.  3. Processing type   Single piece processing: single piece production, rarely repeated production.  Batch processing: batch production of the same parts.   Mass processing: When the product is mass produced, the production of a part needs to be repeated frequently.  When selecting processing, due to different types of parts processing, production methods, equipment, tools, blanks and technical requirements are also different.  4. Processing precautions   a. To facilitate processing operations, minimize unnecessary bending and toe movements.  B. The positioning should be accurate and reliable to prevent vibration and cause errors.  C. The movement direction of the operating parts of the equipment and the movement direction of the operated parts shall meet the specified requirements and shall be clearly marked.  D. Set up necessary interlocking mechanism to prevent unacceptable actions during operation and cause danger.  E. The structure and arrangement of shafts, handwheels and buttons meet the requirements. Generally, the start button should be installed in the case, and a protective ring should be installed to prevent accidental contact. The shaft should be equipped with an automatic prolapse device to prevent the handwheel and handle from being injured.
