Industry Cases

Robotics

Joint components, housings and structural brackets as prototypes and small batches — fit dimensions and weight controlled so the machine actually assembles and runs.

Two words matter for robotics parts: fit and weight

Structural parts on a robot rarely work alone — they mate with gearboxes, bearings and motors. That makes dimensional and geometric tolerance on mating faces more important than appearance. A hole pattern that is slightly out will still assemble, but it will run with noise and extra load.

The other is weight. Every gram removed from a moving part reduces drive power and inertia, so robotics parts are full of weight-saving features: ribs, pockets, thin walls. Those features distort easily during machining and need deliberate attention to workholding and cutting sequence.

The reality of iteration

Robotics development almost never freezes at the first revision. What matters is response to revisions: we keep the previous process plan, fixturing and inspection records, so the next revision only reworks what changed instead of starting process preparation over.

Please tolerance mating dimensions individually on the drawing rather than relying on a blanket general tolerance — that is the single most common cause of rework on robotics parts.

Why Us

Fit dimensions controlled separately

Bearing seats and gearbox mounting faces get their own machining and inspection plan, not lumped in with cosmetic dimensions.

Distortion control on thin-wall parts

Workholding and cutting sequence adapted for ribbed and pocketed lightweight structures.

No restart on revisions

Previous process and inspection records are retained, so a revision only handles what changed.

Fit checked before dispatch

Critical mating dimensions are re-checked before delivery, reducing assembly failures at your site.

Forming Processes

CNC machiningJoints, mounting flanges and structural brackets where accuracy and rigidity matter.
Sheet metalFrames and guards — large thin-sheet structures, low cost and short lead time.
3D printingStyling checks, cable clips and other validation parts with modest strength needs.
Silicone / PU castingSmall batches of soft or damping parts without tooling.

Surface Finishes

AnodisingAluminium structural parts — corrosion protection plus appearance, clear or black.
Bead blastingRemoves tool marks; a pre-anodising step or a matt finish in its own right.
PaintingHousings and guards requiring a specified colour.
Black oxideLow-cost rust protection for steel parts used internally.
