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
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
6061 and 6063 are both heat-treatable 6xxx-series aluminum alloys, but they are not interchangeable. For most machined parts, 6061 is the stronger and more broadly available starting point. For extruded profiles, visible surfaces, and parts where corrosion resistance and anodized appearance matter more than maximum load capacity, 6063 can be
Choosing between MIM and die casting depends on material, geometry, quality risks, tooling, and secondary work as much as annual volume.
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,
Choosing between MIC 6 aluminum and 6061 aluminum is not simply a question of which material is “better.” The correct choice depends on what the finished component must do. MIC 6 is a precision-machined cast aluminum tooling plate engineered for flatness, low residual stress, and dimensional stability. It is commonly
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
Brass and aluminum are both widely used for CNC machined components, but they solve very different engineering problems. Aluminum is usually selected when low weight, a high strength-to-weight ratio, fast machining and flexible surface finishing are priorities. Brass is often preferred when a component requires excellent machinability, clean threads, dimensional
2024 and 6061 are both heat-treatable wrought aluminum alloys, but they solve different engineering problems. 2024 is selected when high strength-to-weight ratio and fatigue performance are central to the design. 6061 is selected when a project needs balanced strength, corrosion resistance, weldability, broad stock availability, predictable finishing, and a lower-risk
Machining 7075 aluminum is a practical route to producing lightweight parts that must carry high structural loads without the mass of steel. The alloy is widely specified for satellite brackets, robotic joints, motion-control components, aerospace structures, high-load fixtures and other parts where strength-to-weight ratio matters. However, a successful 7075 part
Die casting suits repeatable thin-wall aluminum parts at higher volumes, while sand casting fits larger parts, shorter runs, and designs that need more alloy or heat-treatment flexibility. This guide explains how size, tolerances, tooling, machining, and inspection affect the final process choice.
Machining 6061 aluminum is often the starting point for engineers who need lightweight, corrosion-resistant, and cost-effective CNC parts. The alloy offers a practical balance of strength, machinability, availability, weldability, and anodizing response. It is widely used for optical mounts, motion-stage housings, robotic frames, medical-equipment housings, fixtures, brackets, and structural components.
