Clear anodize is often written on a drawing as if it were only a color choice. In precision CNC work, it is a dimensional, electrical, cosmetic, and supply-chain decision at the same time. A part can pass machining inspection and still fail at assembly after anodizing if a bearing bore closes up, a ground contact…
Titanium machining changes toolpaths, fixturing, cost, and inspection planning. Learn what to define on the drawing before requesting a supplier quote.
Learn how to review CNC part geometry, tool access, workholding, tolerances, materials, finishes, and inspection requirements before sending an RFQ.
ULTEM machining is the CNC milling, turning, drilling and finishing of polyetherimide (PEI) stock into precision functional parts. ULTEM is SABIC’s trade name for a family of amorphous PEI resins; the family includes unfilled and reinforced grades that differ substantially in stiffness, tool wear, surface behavior and dimensional response. For buyers, the practical question is…
UHMW-PE can be CNC milled, turned, drilled and routed successfully, but it does not behave like aluminum, steel or even a stiffer engineering plastic such as acetal. The main machining risks are elastic deflection, heat-related dimensional change, long stringy chips, burr or “fuzz” formation and post-machining movement. A reliable process therefore depends on sharp cutting…
Torlon® machining is a specialized form of high-performance polymer machining. Buyers usually reach this topic with a practical question: can a machine shop produce accurate Torlon PAI parts without creating distortion, burrs, damaged threads, dimensional drift, or avoidable material scrap? The answer is yes, but Torlon should not be treated like nylon, acetal, or a…
G10 machining looks straightforward until the cutting tool actually enters the material. Unlike aluminum or conventional engineering plastics, G10 is a glass-fabric-reinforced epoxy laminate. Its combination of woven glass reinforcement and thermoset resin gives the material useful mechanical strength, electrical insulation, moisture resistance and dimensional stability, but the same glass reinforcement that makes G10 useful…
Polycarbonate can be CNC milled, turned, drilled, routed, threaded, and polished with good results, but heat, chip evacuation, residual stress, clamping pressure, and chemical compatibility must be controlled. Sharp tools and a correct chip load are more important than copying one fixed RPM from the internet. Polycarbonate (PC) is a strong, transparent engineering thermoplastic that…
This guide explains how to specify surface finish and cleanliness for semiconductor CNC parts by functional zone, verify test methods and supplier records, and write RFQs.
Nylon (polyamide, PA) is widely used for CNC-machined gears, bushings, rollers, wear pads, guides, insulators and other functional components because it combines low density, wear resistance, useful fatigue performance and relatively low friction. It is also easy to underestimate. Compared with metals, nylon has lower stiffness, lower thermal conductivity, much higher thermal expansion and a…
