FAQs Aout Stainless Steel CNC Machining
Stainless steel is preferred for CNC machining due to its excellent mechanical properties, corrosion resistance, and durability, making it suitable for various industries such as aerospace, automotive, medical, and more.
The most common stainless steel grades used in CNC machining include 304 and 316 stainless steel. We also provide other grades of stainless steel alloys and each grade offers unique properties suited for specific applications.
Stainless steel’s exceptional hardness necessitates high-quality, robust, and rigid machinery and tooling. Its properties can lead to machine chatter, posing challenges during part machining. Thus it is important to optimize cutting parameters to minimize tool wear and prolong tool life, and implement effective coolant strategies to control heat and chip evacuation.
Yes, stainless steel parts can undergo various post-processing operations after CNC machining. These post-processing steps may include deburring, polishing, passivation, surface treatments such as powder coating or plating, and any other finishing processes required to meet the desired specifications and surface quality standards.
