Stainless Steel CNC Machining: Tool Selection and Cutting Parameter Optimization Selecting appropriate tools and optimizing cutting parameters is foundational to preventing deformation in thin-walled stainless steel components. We use carbide tools with sharp cutting edges and large rake angles (7-10 degrees) to minimize cutting forces, reducing the risk of bending or warping. For 304 and 316 stainless steel, we prioritizeMore

Stainless Steel CNC Machining: Tool Material and Coating Selection for Hard Alloys Selecting the right tool materials and coatings is the first line of defense against the hardness challenges in stainless steel CNC machining. For martensitic stainless steels like 440C (38-42 HRC) and precipitation-hardening grades like 17-4 PH (40-45 HRC), we rely on ultra-fine grain carbide tools with grain sizesMore

Stainless Steel CNC Machining: Understanding Passivation Fundamentals Passivation is a critical post-processing step for stainless steel CNC machined parts, focusing on enhancing corrosion resistance through chemical treatment. The process removes free iron particles and contaminants from the surface left by machining operations, which can cause premature rusting if not addressed. We use nitric acid solutions (20-50% concentration) at temperatures betweenMore

Stainless Steel CNC Machining: Cutting Speed Differences Between 304 and 316 Establishing optimal cutting speeds is critical for efficient CNC machining of both 304 and 316 stainless steel, with distinct parameters required for each alloy. 304 stainless steel, with its lower nickel content and slightly higher machinability, performs best at cutting speeds of 120-150 m/min when using carbide tools. ThisMore

Stainless Steel CNC Machining: Material Optimization for Cost Efficiency Material selection and optimization form the foundation of cost reduction in stainless steel CNC machining for both prototyping and mass production. We prioritize standard stainless steel grades like 304 and 316 for prototypes unless specialized properties are required, avoiding premium alloys like 17-4 PH or duplex stainless unless justified by performanceMore

Stainless Steel CNC Machining: Carbide Tooling with Specialized Coatings Selecting the right carbide tooling with advanced coatings is foundational for high-efficiency stainless steel CNC machining. We prioritize micrograin carbide substrates (grain size 0.5-1 μm) that offer superior wear resistance and edge strength compared to conventional carbides, critical for handling stainless steel’s work-hardening tendency. Titanium aluminum nitride (TiAlN) coatings are ourMore
