Stainless Steel CNC Machining Services - Custom Stainless Steel Parts

Stainless Steel is widely used in CNC machining due to its strong corrosion resistance, high hardness, good tensile resistance and good machinability. Shanghai Yixing Machining has made many stainless steel machined parts for different industries like medical, new energy, machinery, automotive, oil and gas etc. If you are looking for professional stainless steel machining factory in China, we are here for you!

What are The Types of CNC Stainless Steel Machining?

Milling

Milling is a machining method that rotates the cutting tool on the workpiece for cutting. Stainless steel has a relatively high hardness, so it is necessary to use high hardness cutting tools and appropriate cutting and feed rates during the milling process. For precision machining, CNC milling machines can also be used for precise control.
Turning

Turning is a machining method that adjusts the width of the workpiece to the design size by rotating the turning tool. Stainless steel has high hardness and high cutting difficulty. In order to ensure machining quality, it is necessary to select blade materials with good cutting performance, frequently replace the blade, and appropriately choose feed rate and cutting speed.

Drilling

Drilling is a machining method of cutting holes on a workpiece by rotating the tool. In stainless steel drilling, due to the high hardness of the workpiece, the drill bit is prone to damage. Therefore, hard alloy drill bits should be selected, with lower cutting speeds and cutting lubrication with cooling lubricants.
Grinding

Grinding is a processing method that uses abrasive particles to grind workpieces. Stainless steel has high hardness and is suitable for grinding with grinding wheels. During the grinding process, appropriate grinding tools and abrasive particles should be selected, and good cooling and lubrication of the cutting fluid should be ensured.

Benefits & Challenges in CNC Stainless Steel Machining

Benefits：

1.Strong corrosion resistance: Stainless steel has excellent corrosion resistance and can be used for a long time in harsh environments such as humidity, acid and alkali, without being corroded.

2.High hardness: After heat treatment, the hardness of stainless steel can reach HRC40 or above. Therefore, the high hardness performance of stainless steel can be fully utilized in CNC machining.

3.Good tensile resistance: Stainless steel has good tensile resistance and can fully utilize its role in machining.

4.Easy to process: Stainless steel has good machinability and can be processed using various methods such as milling, turning, drilling, cutting, etc.

Challenges：

1.Poor plasticity: Although stainless steel has strong toughness, in some machining processes, due to poor plasticity, it is prone to cracking or deformation, so special attention needs to be paid to the machining process.

2.Easy to accumulate: During the cutting process, stainless steel debris is prone to accumulate on the surface of the machining tool and workpiece, reducing machining efficiency and increasing production costs.

3. High temperature is prone to deformation: In high temperature environments, stainless steel is prone to deformation, so it is necessary to control the working temperature during the processing to avoid affecting mechanical processing.

We are well aware of how to utilize the machining advantages of stainless steel, as well as how to control its disadvantages, such as adjusting mechanical parameters, mold materials, temperature control, and creating stainless steel machined parts that meet the requirements of customers’ drawings.

Stainless Steel Grades We Work With

AISI 316

AISI 316 stainless steel has high strength, corrosion resistance, and heat resistance, making it suitable for manufacturing parts with high requirements for corrosion and heat resistance, such as reaction vessels, acid-base storage tanks, and marine equipment in the chemical industry. However, due to the hard nature of AISI 316 steel, the cutting process is relatively difficult and requires professional processing and treatment.

AISI 304

AISI 304 is a commonly used 18-8 stainless steel with good corrosion resistance and weldability. It has good machining performance, deep drawing, bending and welding performance, and is suitable for manufacturing lightweight structures and components, such as bolts, nuts, and screws.

AISI 303

AISI 303 stainless steel belongs to free cutting steel, which is easy to cut during machining and has good surface finish. Suitable for the manufacturing of parts in various automated machines and production lines, such as precision machining, automatic revolving doors, precision instruments and meters, etc.

17-4PH

17-4PH is a high-strength, high hardness stainless steel material with excellent processability and physicochemical properties. It has good machinability after solid solution treatment (1050 ° C to 1150 ° C) and can be processed through conventional cutting processes such as cutting, milling, and turning.

There are many more stainless steel grade that can be used in CNC Machining. Shanghai Yixing has been worked on stainless steel machining parts for more than 10 years. We deeply understand the difference between If you are not sure which grade is best for you, please contact with us and we can give professional suggestions.
