Precautions for machining!

In fact, no matter what is processed, there are matters needing attention, so as to ensure the quality of the products we produce. However, compared with large parts, processing is still relatively difficult, so there are many matters needing attention. So let’s learn about the matters needing attention in machining large parts?

1. Large and medium-sized parts should be equipped with protective equipment before machining, and rubber gloves and necks are strictly prohibited. Before starting the CNC lathe, it is necessary to understand the main purpose and operation steps of each rocker, and check whether all positions of the CNC lathe are running normally. Before starting the CNC lathe, it is necessary to clamp the NC blade and steel parts with a wrench.
2. It is forbidden to start the CNC lathe for machining large and medium-sized parts without the permission of the staff. It is not allowed to touch the running position in the process of speed regulation, chip removal or area measurement before starting. If dirt or cutting is found on the CNC lathe, it is forbidden to take it by hand or blow with mouth.
3. During the machining of large and medium-sized parts, if it is found that the articles are loose or the machine equipment is abnormal, the car must be parked immediately. After the actual operation, the special tools should be removed and the working environment of the CNC lathe should be cleaned. It is not necessary to put the CNC blade, steel parts and other objects on the surface of the machine tool workbench.
4. It is not allowed to touch the CNC blade, steel parts and its running components with hands in the machining of large and medium-sized parts. It is forbidden to lean the human body on the CNC lathe to prevent other safety accidents. When two people operate each equipment together, the division of responsibilities shall be established and close cooperation shall be established.
5. About 40% of the gear transmission noise is caused by rough edges and bumps. Some processing plants remove the burr and bumps before the assembly line of the reducer, which is a common method to prepare the mechanism in advance. Special attention should be paid to the fact that in normalizing or heat treatment, the temperature in the furnace must be kept even, and the fixtures should be selected to make the steel parts evenly heated and cooled by water. It is forbidden to stack them together.
6. Control the quality of raw materials: high quality raw materials are the necessary conditions for the production and manufacture of high-quality commodities. The raw materials used by enterprises, such as aluminum alloy profiles, Q235, stainless steel plates, 50Cr and 46 steel, are used to manufacture non-standard parts such as permanent magnet machinery and equipment, mechanical equipment and automatic machinery. No matter which way, the raw materials must go through rigorous composition detection, grain size measurement and purity identification after arriving at the plant. The aim is to adjust the deformation of quenching and tempering immediately and improve the quality of tooth profile production and processing. The enterprise has strict quality management process, including raw material review, production process management, commodity factory inspection, etc.
