For manufacturers, since there is no special equipment for non-standard equipment, they can only use existing equipment for processing according to customer requirements, and then assemble manually, which makes the quality control of non-standard mechanical equipment change. very challenging. Since there is no unified national standard for non-standard mechanical equipment, the design and production are completely dependent on the information provided by customers, which requires obtaining detailed information as much as possible, including specific technical parameters and requirements for accuracy. During this period, it is necessary to prepare the corresponding equipment and debug it to ensure a good working condition. Specifically, the following aspects should be done:

　　1. The rationality of non-standard equipment design

　　The first is to carry out the corresponding design according to the actual needs of the equipment. In the design process, practicality and economy must also be considered. In the design process, the corresponding parameters should be strictly formulated to ensure that the performance of the equipment can meet the expected purpose. In order to ensure the rationality of the design, corresponding simulation experiments can be carried out to obtain the parameters of the normal operation of the equipment, and the design scheme can be modified and optimized according to these parameters. Carry out scientific design for each component to ensure that its specifications and strength meet the overall requirements of the equipment, so as to avoid the existence of a short board in a component that may cause the entire equipment to run erratically. The strength of the standard parts should be referred to, and the durability of the parts should not be ignored. The failure of the entire equipment will not be caused by the premature aging or damage of a certain part.

　　2. Standard parts should use finished parts as much as possible

　　In the process of non-standard = mechanical equipment manufacturing, standard parts should be used as much as possible, because these finished parts are produced in accordance with the mandatory standards stipulated by the state, and their specifications and dimensions are very standard, and the quality is also guaranteed. In the long-term production process, the production process of these standard parts is very mature and the cost is very low. Even for non-standard mechanical equipment, it is very difficult to completely redesign and make parts, which requires a lot of time and a lot of capital investment. The designed parts have not been verified for a long time, and there are often various problems when used in equipment. It is more advantageous to use standard parts as much as possible.

　　3. Improve the working reliability of non-standard equipment

　　The finished parts of the parts are generally put into the market after repeated practice and testing. Compared with the non-standard parts that are only designed and manufactured for the first time, they have better reliability. When designing non-standard parts for the first time, there will be more or less design defects. These defects are often not improved in time due to economic and time constraints. After using these defective non-standard parts It will reduce the reliability of equipment operation.

　　4. Reduce the manufacturing cost of non-standard equipment

　　When producing a single piece of non-standard parts, the cost is often much higher than the batch production of parts. This makes the cost of non-standard products in terms of raw material consumption, yield, management costs, labor productivity, etc. much higher than that of mass-produced commercial products. Because it is a single-piece production, the design cost accounts for a relatively large proportion of the cost. Some complex components may not be completely successful in one design. Most of them require partial modifications, and some even need to be rebuilt. These situations will lead to higher costs.

　　5. Improve design efficiency and shorten manufacturing cycle

　　When designing and manufacturing parts by yourself, the workload from design to manufacture is often very large, and it takes a lot of time. If the finished parts of the components are used, the time for designing the components by yourself can be shortened, thereby shortening the cycle of equipment design and manufacturing, and improving the design efficiency.

　　6. The accuracy of the assembly of the main components of the equipment

　　The assembly of the equipment starts from the assembly of components, and the assembly accuracy of the components directly affects the final installation accuracy of the equipment. When assembling parts, it is required that the parts be cleaned, equipped with necessary assembly tools, and the external environment of assembly should also be clean. After the components are assembled, the supervisors must test the assembly accuracy of the components.

　　7. The overall assembly quality of the equipment

　　After the overall assembly of the equipment is completed, the assembly quality should be confirmed, the overall assembly accuracy of the equipment should be tested, and it should be checked whether the equipment fully meets the technical requirements. During the equipment manufacturing supervision period, the equipment manufacturing supervisor shall record the key nodes and key parameters in the equipment manufacturing process, and report to the company regularly. The inspection and inspection of equipment processing quality are all completed by the quality inspection department of the equipment manufacturer. The equipment manufacturing supervisors only conduct random inspections or confirmations, and do not replace the work of the quality inspection department. The equipment manufacturing supervisor and the quality inspection department of the equipment manufacturing plant cooperate with each other to do a good job in the control of equipment manufacturing quality.
