Product Description
The key to CNC machining stainless steel mechanical parts lies in adaptability-selecting tools, equipment, and parameters based on the type of stainless steel (austenite, martensite, or ferrite). By optimizing cutting paths, enhancing cooling and lubrication, and strictly controlling machining precision, the machining challenges presented by stainless steel's high toughness and hardness can be overcome. In actual production, the process must be continuously adjusted based on the specific requirements of the part (precision, corrosion resistance, and strength) to achieve the machining goals of high efficiency, high quality, and low cost.
The influence of stainless steel material properties on CNC machining
| Stainless steel type | Mechanical properties | Difficulties in CNC machining | Applicable Scenario | |
| 304,316,316L | High toughness, good ductility, non-magnetic, hardness of about 150-200HB at room temperature | The "tool sticking" phenomenon is easy to occur during cutting, the chips are difficult to break, and the heat dissipation is poor, resulting in high tool temperature. | Food equipment, medical equipment, corrosion-resistant pipeline parts | |
|
Can be heat treated and strengthened, hardness reaches 50-60HRC after quenching, high strength | High hardness leads to rapid tool wear, high cutting force, and easy tool chipping | Cutting tools, valve cores, high-strength structural parts | |
| 430,409L | Medium hardness (140-180HB), toughness lower than austenite, magnetic | The cutting performance is better than austenite, but the cutting temperature still needs to be controlled to avoid poor surface roughness. | Home appliance parts, decorative parts, heat-resistant parts |
about Us
Xi 'an Hi-Precision Machinery Co., Ltd provides CNC machining stainless steel mechanical parts service across various industries. We prepare blanks through precision casting, then process them through CNC lathes, milling machines, and other equipment to achieve precise finishing of holes and slots, followed by mirror polishing. Finally, we use coordinate measuring machines for inspection, ensuring stable production and meeting customer drawing requirements.
Manufacturing process
1
CNC milling is used to manufacture special-shaped structures such as planes, contours, grooves, etc.
2
CNC turning is used to manufacture shaft and disc parts.
3
Choose cobalt-containing high-speed steel drill bits or carbide drill bits.
4
Use forming taps (chip-free, strong threads) instead of cutting taps.

How to ship ?
To avoid quality issues during transportation, we pre-treat parts before packaging. For example, we remove cutting fluid, iron filings, and oil stains from the surface of the parts. Small parts are cleaned with an ultrasonic cleaner (using a neutral detergent), while large parts are cleaned with a high-pressure air gun and denatured alcohol. Rust-prone materials like stainless steel and carbon steel are also dried with compressed air or coated with a thin layer of rust-inhibitor (food-grade or medical-grade parts require food-grade rust inhibitors).
By default, we use EPE foam and cartons for packaging, and ship by DHL or UPS. If you need to specify the packaging method or delivery method, please contact us.
