Stainless steel, known for its strength, durability, and corrosion resistance, is preferred for countless applications ranging from medical devices to automotive parts. Its machinability allows for creating complex shapes and precise tolerances with smooth finishes, essential for custom parts requiring high precision.
Types of stainless steel suitable for CNC machining
In CNC machining, selecting the right type of stainless steel is pivotal for balancing machinability with application requirements.
- For high corrosion resistance and formability, 304 and 316L austenitic grades are preferred, offering easy machining for complex parts.
- For parts demanding hardness and wear resistance, 410 and 416 martensitic steels are chosen, as they can be easily machined and hardened.
- Meanwhile, 17-4PH stands out in the precipitation-hardened category for its exceptional strength and machinability, making it ideal for aerospace and medical devices.
- Duplex stainless steels like 2205 blend strength with corrosion resistance, suitable for harsh environments.
CNC Machining Processes for Stainless Steel Parts
The CNC machining of stainless steel parts encompasses a variety of processes, each chosen based on the part’s design specifications and intended use.
CNC Milling
This versatile process uses rotary cutters to remove material, allowing for the creation of complex shapes, slots, holes, and notches with high precision.
CNC Turning
Ideal for producing cylindrical parts, turning operations involve rotating the stainless steel workpiece against a cutting tool.
Drilling and Tapping
These processes are critical for adding functional features to stainless steel parts, such as through holes for fasteners or threaded holes for assembly.
