Process analysis is the pre-process preparation for hardware CNC turning. Whether the process is reasonable or not has an important impact on the later programming, the machining power of the machine tool and the machining accuracy of the parts. In order to compile a reasonable and useful machining program, the programmer is required not only to understand the operating principle, functional characteristics and structure of the CNC lathe. Master the programming language and programming format, and also master the workpiece processing technology, determine the reasonable cutting amount, and correctly select the tool and workpiece clamping method. Therefore, we should follow the general process guidelines and combine the characteristics of CNC lathes to analyze the CNC turning process of hardware parts processing in detail.
Precision hardware can be cut according to production needs, and then some small accessories can be cut or CNC processed, and precision hardware must be used as a container for cutting and punching, followed by welding, then sanding, and oil injection. After the accessories are made done. It should be reminded that small parts also need to be electroplated or sprayed on the surface after grinding. There are many cases of batch processing of precision metal parts, so the production method and cycle of precision metal processing are different from the operating specifications and processes of general product processing.
We need to look at things like a workholding fixture to make sure it's sturdy and that it doesn't promote harmonic issues or vibration during machining. We need to make sure we don't use unnecessarily long tools that can easily turn or increase the chance of chattering. In high-speed processes, we need to ensure that we use a mass-balanced tool that is rated according to the programmed RPM used. But what if all the things mentioned above are fine?
Plastic CNC machined parts is one of our main products, which including general engineering plastics processing-Nylon, Delrin, PP, PC, PET, FR4, UHMW-PE,PVC; High performance plastics(China plastic CNC machined parts)
PEI (Chinese name polyetherimide) is a thermoplastic engineering resin with an amber transparent solid appearance. It has excellent heat resistance, high strength and rigidity, as well as a wide range of chemical resistance, which can meet higher heat. Chemical and elastic demand. Its unique torsional strength among thermoplastics makes it an inexpensive alternative to small steel cutting parts.
PPSU (Chinese name: Polyphenylsulfone) is a high temperature resistant plastic with obvious advantages. Compared with other transparent plastics, it has higher toughness, strength and hydrolytic stability, and can withstand long-term exposure to water, chemicals and a wide working environment temperature of -40℃-180℃.
