Industry Cases

UAV & Drones

Arms, gimbal mounts and airframe parts: weight driven down without losing strength, and matched sets kept consistent.

Weight is the first constraint

Every gram on a UAV costs endurance, so structural parts run thin and heavily pocketed. That creates two practical machining problems.

Distortion. Thin walls deflect and spring back under clamping and cutting loads. A part can measure in tolerance off the machine and drift overnight. Controlling it means separating roughing from finishing, allowing time for stress relief, and choosing clamping points deliberately.

Consistency. A multirotor has several arms. If their stiffness or mass differs, the flight controller spends effort compensating. So a matched set is produced in one batch on one fixturing plan, not assembled from whatever was made when.

On materials

Aluminium and carbon fibre are a common pairing. Carbon fibre machining must be confirmed separately — the dust has implications for both equipment and personnel. State the part material when enquiring.

Why Us

Thin-wall distortion control

Roughing and finishing separated with stress relief scheduled, avoiding parts that drift out of tolerance overnight.

Matched sets in one batch

A set of arms is produced in one batch on one fixturing plan for consistent stiffness and mass.

Weight as an acceptance criterion

Finished parts can be weighed and recorded as part of the delivery evidence.

Composites confirmed up front

Scope for carbon fibre and similar materials is settled at quotation, not left vague.

Forming Processes

CNC machiningArms, motor mounts and gimbal brackets — load-bearing structures.
Sheet metalBattery bays and shielding cans and other thin-sheet parts.
3D printingAerodynamic form checks and internal cable retention parts.
Carbon fibreTo be confirmed — state the material when enquiring so an engineer can confirm scope.

Surface Finishes

AnodisingThe default for aluminium parts; the added mass is negligible.
Bead blastingA matt finish that also makes surface defects easier to spot.
PaintingCosmetic parts to a specified colour; note the coating adds weight.
Screen print / laser markingModel and orientation markings; laser marking adds no weight and resists wear.
