The material requirements of cnc processing for precision parts processing

For precision parts processing of small hardware, most of the small hardware products are not final consumer goods. It can also be used as auxiliary products for industrial production, semi-finished products and tools used in the production process, etc. Only a small part of daily hardware products are tools and consumer goods necessary for people's daily life. For example: screws, screwdrivers, wrenches, fishing gear, etc. Precision parts refer to machine parts or components made of hardware and some small hardware products. Can be used alone or as an assistive device.

The processing of precision parts in many CNC processing plants is based on production needs, ordering steel materials from raw material suppliers, and then starting the machine after the steel materials are ordered, and then starting the machine. The tolerances are inspected on four sides, and the small details after inspection, such as small parts production, can be directly taken to the punch and then processed by milling or CNC computer gong processing. These are details about the production of eyeglass accessories and auto accessories. And the production of the container is almost after the material is cut, and then the punching machine can be directly taken out and welded, and then sanded and then sprayed with oil, and then assembled with some accessories to be shipped perfectly.

So what material can be used for precision parts machining? I will give you a detailed introduction today.

The hardness of some materials is too high, exceeding the hardness of the machined parts, which will cause the parts to collapse, so these materials are not suitable for precision machining unless special materials or laser cutting are used.

On the whole, the precision parts processing of our CNC processing factory in Dongguan is divided into two categories, metal and non-metal, that is, belong to the metal category.

Among them, the metals include: stainless steel has the highest hardness, followed by cast iron, copper, and aluminum.

Among them, non-metals include: ceramics, plastics and other processing.

In short, there are still certain material requirements for precision parts processing, not all materials are suitable for processing, such as too soft or too hard materials, the former is unnecessary, and the latter is not machinable. Therefore, the most basic one is that you must pay attention to the density of the material before processing. If the density is too large, it is equivalent to a large hardness, and if the hardness exceeds the hardness of the machine parts (lathe turning tools), it cannot be processed, not only It will damage the parts, and it will also cause danger, such as the turning tool flying off, hurting people, etc. Therefore, in general, for mechanical processing, the material should be lower than the hardness of the tool, so that the processing can be carried out.
