Today, mechanization and automation have become the mainstream of industry development. Raw material specifications, properties, material usage, machine vibration, clamping pressure or looseness, inspection methods, inspector errors, etc., all have an impact on the quality of processed products. When we talk about the quality of a working prototype, it's not hard to think of the following 4 main factors:
1. Operator
As machine functions become more complex, the level of programming and operators varies widely. Combining the superb skills of humans with computer information technology can maximize the use of machines. To do this, machine operators must be familiar with equipment performance. If the operator does not know enough about the performance of the equipment, he may misuse it, thereby accelerating the wear of the machine parts for CNC machining parts, and even causing damage to the machine.
2. Machines
A complete CNC machining parts processing system consists of machine tools, workpieces, fixtures and tools. Machining accuracy is related to the accuracy of the entire process system. Various errors of the process system will manifest as machining tolerances in different forms under different circumstances.
Machine accuracy is an important factor affecting the quality of prototype parts. When the precision of the machine is poor, some CNC machining parts are damaged or the gap of each part is not adjusted properly, various defects will appear in the prototype during the machining process.
3. Materials
Machining materials are generally divided into plastics and metals. Each material has its own characteristics. It is also important to select the appropriate material according to the requirements and application of the workpiece during the machining of CNC machining parts. Material consistency is better, otherwise the quality of the same part may vary. When the hardness of the material is suitable, try to ensure that the material is not deformed. These are important prerequisites for assessing quality.
4. Inspection
After the machine has finished machining the CNC machining parts, inspection is the last critical step before delivery to the customer. Machining inspection generally needs to pay attention to two aspects:
（1）Inspection procedure - The inspection process includes the inspection process, as well as relevant regulations, systems, standards, etc. Generally speaking, the inspection process is to inspect the intervention and intervention methods in the production process, including first inspection, self-inspection, mutual inspection and full-time inspection.
（2）Inspection method - refers to how to inspect and inspect the standard. The inspection of CNC machining parts is generally based on mechanical drawings, and the products are inspected through inspection instruments and measuring tools.
