In precision manufacturing, stainless steel is a mainstream material that balances structural strength, corrosion resistance and overall cost-effectiveness, widely used in medical, food, aerospace, marine and other industries. Many buyers new to stainless steel milling often wonder why it costs so much more than aluminum — this is not supplier markup, but a higher processing threshold determined by the material properties of stainless steel. Four core challenges: work hardening, built-up edge, low thermal conductivity and poor chip evacuation, collectively drive up processing costs and technical requirements.

This comprehensive guide covers CNC milling of titanium alloys, including grade selection (Ti-6Al-4V, Grade 2, ELI), tooling strategies, cutting parameters, surface finishing, tolerances, and aerospace & medical applications. It helps buyers understand the cost structure and quality requirements of titanium machining, and select the right precision manufacturing solution.

Aluminum alloy is the most commonly machined metal in CNC manufacturing, valued for its light weight, corrosion resistance and excellent machinability. This article provides a comprehensive overview of key knowledge for aluminum milling, covering material characteristics, popular alloy comparisons, cutting parameter tables, tool selection, common defects and anodizing post-processing, helping you avoid pitfalls in parameter selection and quality control.

CNC milling tolerances determine whether a part meets qualification standards. This article systematically sorts out the full knowledge of tolerance control from six dimensions: ISO 2768 standard system, IT tolerance grades, achievable accuracy of 3/4/5-axis machining, key influencing factors, drawing specification rules and measurement methods, helping you make reasonable and cost-effective tolerance choices at the design stage.
