Custom Joint Housings — NDA Protected, Built to Drawing. Dongguan Changxinda Precision Technology Co., Ltd. machines fully custom, non-standard robot joint housings to your drawing or 3D model — any cavity size, bearing bore, wall section, flange pattern or motor interface.
Since 2008 the factory has built one-off prototypes and scheduled production batches for 200+ customers across ten industries, exporting 50–60% of its output overseas. Critical features — cavity, bearing bore and mounting faces — are held to ±0.01 mm and verified on a CMM, whether you order one prototype or a recurring batch.
- 100% Custom
- NDA Ready
- ISO 9001:2015
- 90+ Staff
- Prototype to Mass Production
- MOQ 1 Piece
Custom does not mean uncertain. Our workflow keeps you in control from drawing to delivery:
- 1Send drawings: 2D PDF, STEP, IGES or SolidWorks — or a physical housing to reverse-engineer.
- 2DFM review: engineering feedback on cavity depth, wall thickness, bore fit and interface strength before you commit.
- 3Quote in 24h: transparent pricing by drawing and quantity, no tooling charge.
- 4Program & fixtures: dedicated CAM, soft jaws and custom fixtures for your joint geometry.
- 5CNC machining: turn-mill cavity, bore and faces to ±0.01 mm.
- 6Finish & inspect: anodizing, hard coat or per drawing, then CMM dimensional report.
- 7Ship: protected export packing to your schedule.
Non-standard is our normal work. Hollow and hollow-bore joints, L-type and offset housings, weight-reduction slot patterns, sealed joints and dual-bearing designs — all machined to print.
Confidentiality is a condition of the job, not an add-on. We sign an NDA before engineering review, limit drawing access to the assigned programming and machining team, keep fixtures and programs dedicated to your program, and scrap surplus or reject parts on request. You keep the IP; we keep it that way.
Changxinda is a 2008-established CNC factory with 90+ staff, CNC lathes and 4-axis / 5-axis machining centers backed by a dedicated QC lab.

Yes — that is our core work. Send a 2D drawing, STEP/IGES/SolidWorks model or a physical housing and we machine the cavity, bore, flange and slots to print.
Yes, routinely. Drawings are limited to the assigned programming and machining team, fixtures and programs stay dedicated to your part, and surplus or reject parts are scrapped on request.
One piece. There is no tooling or setup charge, so single prototypes are practical and mass production runs on the same inspection standard.
Capacity is planned per program. Prototypes ship in 3–7 days, small batches in 7–14 days and production volumes in 14–30 days, with supply ability up to 10,000 pieces per month.
Yes — send a sample and we measure the cavity, bore and interfaces, then quote a drop-in equivalent with a CMM report and matching fit.
Yes. Hollow-bore and cable-routing joints are routine, with through-bore and bearing seats machined coaxially to ±0.01 mm.
