Medical Device CNC Machining: Which Inspection Documents Should Buyers Request?

Medical device CNC machining buyers should request inspection documents tied to the released drawing, material lot, measured results, and controlled processes. This guide explains which records to request, when they apply, and how to define them in an RFQ or purchase order.

416 Stainless Steel CNC Machining for Precision Machined Parts

416 stainless steel is a free-machining martensitic stainless steel designed for precision components that require efficient turning, milling, drilling, threading and other extensive machining operations. Its sulfur addition improves chip breaking and reduces cutting resistance, while its martensitic structure allows the material to be hardened and tempered when higher strength

15-5 PH vs 17-4 PH Stainless Steel CNC Machining: Which Is Better for Precision Parts?

15-5 PH and 17-4 PH are both martensitic precipitation-hardening stainless steels used when a component needs substantially more strength than conventional 300-series stainless steel while retaining useful corrosion resistance. For CNC machining, however, the two grades should not be treated as interchangeable. The final choice affects raw-material availability, transverse mechanical
Precision turned and threaded components for high strength OEM assemblies

15-5 PH Stainless Steel CNC Machining for High-Strength Precision Parts

15-5 PH stainless steel CNC machining is used for precision components that need a combination of high mechanical strength, good corrosion resistance, dimensional stability and reliable performance under demanding loads. Also identified as UNS S15500 and commonly specified under precipitation-hardening stainless steel standards, 15-5 PH is closely related to 17-4
17-4 PH Stainless CNC Steel Machining

17-4 PH Stainless Steel Machining: A Practical CNC Guide for Precision Parts

17-4 PH stainless steel machining is commonly specified for precision components that require significantly higher strength than 304 or 316 stainless steel while retaining useful corrosion resistance and dimensional stability. The most important machining decision is not simply choosing 17-4 PH stainless steel. Engineers must also define the required material

18-8 Stainless Steel CNC Machining for Precision OEM Components

18-8 stainless steel is widely used for corrosion-resistant fasteners, threaded shafts, sensor hardware, adjustment components and precision mechanical parts. However, for an OEM mechanical engineer or sourcing team, specifying only “18-8 stainless steel” may not provide enough information for a precision CNC machining project. 18-8 generally refers to a family

18/10 Stainless Steel CNC Machining for Precision Equipment

When a drawing, legacy bill of materials or supplier note calls out “18/10 stainless steel,” the first machining decision is not tool selection. It is material identification. The term describes a chromium–nickel composition commonly associated with the 304 family, but it is not a complete engineering grade or purchasing specification.

Brass vs. Stainless Steel for CNC Machining: The Engineering Answer

Brass and stainless steel can both produce accurate, durable CNC machined components, but they solve different engineering problems. Brass is a copper-zinc alloy family valued for machinability, conductivity and low-friction performance. Stainless steel is an iron-based alloy family containing sufficient chromium to form a protective passive film; depending on the

How to Handle Surface Oxidation of Brass, Bronze and Copper Parts

Short answer: Do not select a cleaning method from color alone. First identify the alloy, oxidation severity and functional surfaces. Light tarnish may need controlled cleaning; active corrosion or pitting requires engineering review. After treatment, protect the surface with an application-compatible finish and dry packaging. For UHV, optical and semiconductor

Stainless Steel 303 vs 304 vs 316: How to Choose for CNC Machined Parts

Stainless steel 303, 304, and 316 are all austenitic 300-series alloys, but they solve different manufacturing problems. Type 303 adds sulfur to improve chip breaking and machining productivity. Type 304 is the versatile baseline for corrosion resistance, forming, and welding. Type 316 adds molybdenum to improve resistance to pitting and
