Stainless Steel Machining Parts

KS Machining is a professional China cnc machining factory who has rich experience and best skills on custom manufacturing stainless steel machined parts.

304/316 stainless steel custom machined parts are often met in cnc machining industry. For the metal machining parts, stainless steel is one of the difficult materials to be machined. If correct cnc cutting tools are selected, cnc machining process could get the quality surface smoothness and manufacturing efficiency for custom stainless steel cnc machining parts.

In the mechanical cnc machining industry, stainless steel is widely used for custom precision parts and components on many applications.  The main reason is that stainless steel is not easy to rust. In fact, some stainless steel materials have both non-rust and acid resistance (corrosion resistance) properties. The corrosion resistance of stainless steel is due to the formation of chromium-rich oxide film (passivation film) on its surface. This kind of rust resistance and corrosion resistance are relative. The test results show that the corrosion resistance of steel in weak medium such as atmosphere, water and oxidizing medium such as nitric acid increases with the increase of chromium content in the steel. When the chromium content reaches a certain percentage, the corrosion resistance of steel changes abruptly, that is from easy rusting to difficult rusting, from non-corrosion resistance to corrosion resistance.

Stainless steel materials cause great wear to the cnc cutting tools. CNC machinists need to spend a lot of time on sharpening cutting tools repeatedly, which directly affects the efficiency. Later, the 0.6R six-sided tool made in Japan was selected, which is a cobalt-containing tool. It is full precision grinded and made of 6542 high speed steel. Although the cost of cutting tools is higher, it is acceptable. This cutting tool is durable, and it can effectively reduce the time of repeated sharpening, and reduce the labor cost ,  and finally improve the benefit by about 30%, and meanwhile ensure the custom stainless steel parts manufacturing efficiency.

Machine tool coolant liquid is also very important, because the heat brought by stainless steel machining is extremely high, damaging the cutting tools, producing lumps and affecting the smoothness of custom stainless steel machined parts after cnc machining. Special cutting tool liquid for stainless steel must be selected to ensure the quality of custom stainless steel machining parts.

If you want to make the small threaded holes on custom stainless steel parts, you should firstly select the tap and drill with big brand. Secondly, it is necessary to select special stainless steel tapping oil, which will be much easier to process. Do not use ordinary engine oil or paraffin oil, which have poor tapping effect.

Surface finishing of custom stainless steel parts are generally brushing, polishing and precision grinding. Stainless steel spare parts used on food machinery, laser machinery and other automation equipment may need polishing surface treatment. Precision grinding surface treatment is mainly adopted to make stainless steel parts meet strict tolerance requirements, such as precision tools and fixtures, high precision automation equipment stainless steel parts always need to be precision grinded.
