1. Material accounting and material input is one of the important aspects to improve material utilization and achieve rough refinement. Too much material will not only cause waste, but also increase the wear and energy consumption of boring. If the raw material is not left with a little margin, the difficulty of process adjustment will increase and the scrap rate will rise. In addition, the quality of the raw material end face also affects the quality of the process and forgings.

2. spindle forging manufacturer heating is to reduce the forging deformation force and improve metal plasticity. But heating also brings oxidation, decarburization, overheating, overburning and a series of other problems. Correct control of the starting forging temperature and final forging temperature has a great impact on the organization and performance of the product.

3. Flame furnace heating has the advantages of low cost and high applicability, but the heating time is long, prone to oxidation and decarburization, and the working conditions of the spindle forging manufacturer also need continuous improvement. Induction heating has the advantages of fast heating and less oxidation, but poor adaptability to changes in product shape and size and material.

4. Since forging and forming is caused by external forces, accurate calculation of deformation force is the basis for selecting equipment and conducting die calibration. Analysis of the stress-strain inside the deformed body is also the key to optimize the process and control the organizational properties of forgings.

5. Therefore, the spindle forging manufacturer's spindle forging quality analysis work is generally divided into the site investigation stage, experimental research and analysis stage, the solution measures proposed and preventive measures stage. Spindle forging manufacturer in the implementation of these stages of work before the implementation plan can be developed. The content includes the characteristics of the work to be carried out in these three stages, work procedures and completion time. This implementation approach can be supplemented and modified as appropriate during implementation. The development of the implementation plan is an important part of the analysis of the quality problems of large and complex forgings and used parts.

During the site visit stage, the main purpose is to find out the material variety, chemical composition, material specifications, test results on the material guarantee sheet of the raw materials used in spindle forgings, as well as the results of various physical and chemical tests and process performance tests for re-inspection into the plant, and even the smelting and processing process of raw materials. At the same time, spindle forgings manufacturer of the forging process situation should also be investigated, including the raw materials that should be used for forgings, specifications, raw material input process, forging heating start forging and end forging temperature, the use of forging equipment, heating equipment, heating process, the operation of forging, the cooling method after forging, preheating treatment process situation. If necessary, the spindle forging manufacturer will also investigate the condition of the staff and environmental conditions and the original records of the execution process. For the post-process and use of forging quality children's problems, the technology of the post-process should also be investigated.
