Manufacturing
How we make this part
Process, material options and inspection for cnc turned aluminum control handles and furniture knobs.
Simple round knobs are turned complete on CNC lathes; knobs with off-axis features, sculpted grips or angled faces are finished on 5-axis milling centers, which can blend curved shapes in one setup. Shaft bores, set-screw holes or threaded studs are machined to suit the mounting method. Diamond-cut edges on a lathe add a bright chamfer that contrasts with anodized color.
6063 anodizes with very even color, making it good for visible decorative knobs; 6061 is stronger for handles that take leverage. Brushed finishes give a stainless-like look at lower weight and cost, while bead blasting provides a soft matte feel. Brass or stainless versions feel heavier, which some users read as higher quality. Laser engraving adds icons or scales.
Bore fit and set-screw thread are checked on every part, and anodize color is compared with an approved master sample. Cosmetic surfaces are inspected under consistent lighting, and edges are checked for burrs that a user's fingers would notice. Typical applications include furniture and cabinet knobs, appliance control handles, car audio volume knobs, machine control levers and lighting dimmer knobs.
FAQ
Frequently asked questions
What is a diamond-cut edge on an aluminum knob?
It is a bright, mirror-like chamfer or face cut on the lathe after anodizing, with a very sharp single-crystal or polished tool. It exposes bare aluminum that contrasts with the colored anodize. A clear protective coat is sometimes applied to keep the edge bright.
Should a handle be aluminum or stainless steel?
Aluminum is light, colorful and cheaper to machine, ideal for most furniture and appliance knobs. Stainless steel is heavier, more scratch resistant and better for bathrooms, outdoor or commercial kitchens. Brass gives a premium weight and can be plated.
