Manufacturing

How we make this part

Process, material options and inspection for cnc turned brass and steel lighting fittings.

Fittings are turned on CNC lathes with live tooling, producing threads, knurls and decorative grooves in one setup. Hollow fittings for cords are drilled and deburred inside to protect insulation. Decorative profiles follow customer drawings or reference samples. Small batches allow restoration projects to recreate fittings that are no longer made.

Brass C36000 is ideal for decorative fittings: it machines cleanly and can be polished and lacquered, aged with patina or plated in nickel or chrome. Steel fittings are zinc plated or powder coated, while stainless steel offers a modern brushed look. Aluminum is anodized for lightweight fittings. Cord paths need smooth edges to prevent cable wear.

Threads, cord bores and decorative profiles are checked on every lot, and finishes are inspected for consistency. Critical dimensions are checked before packing. Typical products include socket shells, threaded nipples, cord grips, lamp finials, decorative knobs, lock nuts and swivel parts for vintage restorations and modern lamp designs, in small or medium batches.

FAQ

Frequently asked questions

Can you replicate vintage lamp fittings?

Yes. Send a sample or photos with dimensions, and we will model and machine replicas in brass or steel. Finishes such as polished, lacquered, aged patina or nickel plating can match the original look. A first sample is supplied for approval.

How do you protect cords from sharp edges in lamp fittings?

Cord bores are chamfered and deburred inside, and edges at cord entries are radiused. Fittings can also be designed with plastic bushings or grommets. Smooth cord paths prevent insulation damage, which is a key electrical safety factor.

How do I get a quote for cnc turned brass and steel lighting fittings?

Send a 3D model (STEP or IGES) and a 2D drawing with tolerances, material, finish and quantity through the quote form or by email. An engineer replies within 24 hours on business days with price, lead time and any DFM suggestions.
