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 PH but is valued for…
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 condition—such as Condition A, H900,…
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 of austenitic stainless steels containing…
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. That distinction matters in photonics,…
316 stainless steel is selected when a component must combine corrosion resistance, mechanical durability, cleanability and dimensional stability. These requirements appear in very different products—from ultra-high-vacuum interfaces and low-dead-volume fluidic manifolds to rowing-boat mounting pins and medical-device hardware. The applications vary, but the manufacturing question is the same: can the supplier machine the part without…
Geometry, material, tolerance, testing, and documentation determine which metal prototype process fits an OEM part.
Quick answer: Machine 304 with a rigid setup, sharp positive-geometry tooling, enough feed to form a real chip, controlled engagement, reliable chip evacuation, and coolant delivered to the active cutting zone. Avoid dwell and repeated light rubbing passes because they can work-harden the surface. 304 stainless steel is widely specified for food-processing and botanical-extraction…
303 stainless steel machining is frequently selected for precision components that require stainless-steel strength and moderate corrosion resistance but must also be produced efficiently. Type 303 is a free-machining austenitic stainless steel. Its sulfur addition promotes chip breaking, reduces the tendency to produce long stringy chips and allows it to be machined more efficiently than…
Rollyu Precision provides custom stainless steel CNC machining services for complex parts that need corrosion resistance, strength, repeatable dimensions and dependable surface quality. We machine 303, 304, 316L, 416, 420, 440C, 17-4PH and 15-5PH stainless steel for prototypes and production components used in dental equipment, medical devices, photonics, food machinery, vacuum motion systems and motion…
When a large aluminum plate must stay flat after pockets, vacuum channels and mounting patterns are machined, material stability often matters more than headline strength. That is where MIC6 aluminum and other cast tooling plates earn their place. MIC6 is a proprietary precision cast aluminum tooling plate engineered for low residual stress, close thickness tolerance…
