Stainless Steel Alloys For CNC Machining

Stainless steel CNC machining is a manufacturing process that uses computer numerical control (CNC) machines to shape and cut stainless steel into precise and complex parts or products.

 During the CNC machining process, a computer program is used to control the movement and operation of the cutting tools, which allows for highly accurate and repeatable cuts. This results in parts with tight tolerances and complex geometries, which are difficult or impossible to achieve using traditional machining methods.

 With a wide selection of stainless steel variations, we have everything you need to complete your CNC machining project with precision and excellence. From Stainless Steel 304/304L and 316/316L to 303 or Type 360 (17-4) etc, our options are guaranteed to deliver the highest quality performance that meets any specifications or requirements you may have! 

Including but not limited to the following materials

Stainless Steel 303

Easy to machine, good corrosion resistance, not suitable for welding, ideal for nuts, bolts.

Stainless Steel 304/304L

Corrosion resistant, good formability, widely used in kitchens, tubing, and outdoors.

Stainless Steel 316/316L

Higher corrosion resistance than 304, marine grade, used in harsh chemical environments, surgical instruments.

Stainless Steel 416

High machinability, lower corrosion resistance, magnetic, commonly used for gears, valves, and pump shafts.

Characteristics Of CNC Machining Of Stainless 

Stainless steel material is more difficult to process than steel, not only considering the processing problems but also the performance of different types of stainless steel to choose the corresponding processing technology. The machining quality and efficiency can be guaranteed by a reasonable selection of tool materials, geometric parameters, and cutting parameters

CNC Turning

Stainless steel in the cutting process, severe hardening, plastic deformation, high thermal strength, and cutting force. And poor thermal conductivity, the heat taken away by the chip is very little, and cutting heat is mainly concentrated in the tool near the edge, resulting in rapid tool wear.

Under the same conditions, stainless steel and other metals with strong affinity, easy to make the tip of the chip tumor and after the tool surface to produce adhesion, resulting in rapid tool wear. And because the frequent sharpening, and tool replacement, affects productivity.

In the cutting process, the machined surface is easy to form a hardened layer. As the stainless steel plasticity and toughness are relatively large, the chip is not easy to break, both affect the smooth operation, the processed surface damage is also large, so it is not easy to obtain a lower value of surface roughness.

CNC Milling

The difference between milling and turning is that milling is intermittent cutting, the cutting process of each tooth depth of cut changes all the time, easy to produce vibration and impact, so the cutting conditions are worse than turning. In reverse milling, the tool teeth first in the hardened surface glide, increasing the tendency of hardening; milling impact and vibration so that the tool teeth are easy to chip and wear.

So should be used as far as possible with the down-cut milling method, can ensure that the cutting edge is smoothly cut away, the cutting brow bonded contact area is small, and in the role of high-speed centrifugal force is easy to be used up, to avoid the cutter teeth re-cutting into the workpiece due to chip impact on the front surface of the tool to produce flaking and chipping phenomenon, improve the durability of the tool

CNC Grinding
The grinding force of stainless steel is large and the grinding temperature is high. Under the action of high temperature and high pressure, Scraps will adhere to the working surface of the grinding wheel and block the pore of the grinding wheel, making the cutter lose the cutting effect. The rubbing temperature can reach 1000-1500 degrees Celsius so that the workpiece surface is easy to burn, the depth can sometimes reach 0.01mm ~0.02mm. And because of the action of grinding heat, the workpiece is easy to deform, resulting in size and shape error

CNC Machined Stainless Steel Applications

Many industries, including medicine, robotics, and aerospace, rely on CNC machining of stainless steel to create high-strength parts. This strong material can be used in applications like food packaging that require reliable durability or machinery operating in extreme temperatures. In short, it’s the ideal solution for any situation where reliability matters most!
