CNC precision parts processing is an advanced processing skill in today's machinery manufacturing industry. It inputs the CNC program of the machined parts into the CNC machine tool, and the machine tool automatically processes the workpiece after receiving the CNC program. CNC machining skills can effectively solve the complex and small-scale and changeable processing solutions of hardware parts, and meet the needs of modern production.
People often say non-standard parts processing, so how much do you know about the characteristics of CNC non-standard parts processing! I will share with you the characteristics of CNC non-standard parts processing!
There are many reasons for the workpiece overcut in cnc processing. If the workpiece is overcut, it will be repaired after welding, and the workpiece will be discarded directly. Especially when the large mold is processed, it is the most troublesome thing to encounter the workpiece overcut. How to deal with it, I will share with you my work experience below.
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?
