Introduction to hole processing technology of mobile boring machine

Edit:Xinxiang Blueprint Machinery Co., Ltd.UpDate:2018-10-09

With the continuous development of living standards, people's requirements for all aspects of products have become more and more stringent, so a rigorous and efficient processing process can make products more popular.

The hole processing of the mobile boring machine is mainly to use various props on the machine tool to process the holes of the product, usually divided into drilling, reaming, boring, emptying, reaming, etc. The rough machining method of the hole when drilling ,

Hole processing is mainly to use various tools on the machine tool to process holes in the product, usually divided into drilling, reaming, boring, reaming, pulling, etc. Among them, drilling is the rough machining method of the hole, usually used for 0.05 For hole processing of -100mm, the dimensional accuracy of the hole is IT10 and lower, and the surface roughness is about Ra12.5μm. Drilling is often used as a pre-processing for boring because of its low precision.

The dimensional accuracy of the boring machine can reach about IT7, and the surface roughness can be controlled at Ra12.5-0.8μm, so it is often used for rough, semi-finishing and finishing of different apertures. Although the reaming process is finer than drilling, However, its dimensional accuracy is only about IT10, and its surface roughness is Ra12.5-6.3μm. In order to make finer holes, it often becomes the preprocessing treatment of reaming technology. Reaming is a kind of hole finishing technology. , the dimensional accuracy is mostly IT9-6, and the surface roughness can be controlled between Ra3.2-0.2μm. The drawing hole has high precision and production efficiency, the dimensional accuracy is IT9-7, and the surface roughness can be controlled to Ra1. 6-0.8μm, but due to the high cost of tools, it is more suitable for mass production rather than single processing.

However, the boring machine manufacturer reminds you that regardless of the method, general welding is only to make holes that meet people's needs. Only by choosing a method suitable for your product can you maximize the potential of the product.
