CNC Machined Brackets

Core Advantages

No Welded Corner Joint

The bracket body is milled from stock rather than assembled from welded plates. Where two mounting legs meet, the transition remains within one piece of material, removing weld geometry and welding distortion from that joint while retaining the section defined by the drawing.

Coordinated Mounting Legs

Working faces and attachment holes are machined to the same bracket datum scheme. When an instrument mounts on one leg and the machine base attaches to the other, the relationship between those interfaces controls their assembled orientation rather than the shape of an unfinished blank.

Lower Moving Mass

6061 aluminum provides a lower-density alternative to steel for the same bracket geometry. On an instrument carriage or moving module, the lighter bracket contributes less mass to the axis and therefore less inertia during acceleration and deceleration.

Customization Capabilities

Bracket production follows the approved drawing or sample. We establish the mounting references, rough the body from stock and finish the working features in a planned sequence, with any change needed for cutter access confirmed before machining.

Quality Control

Material certificates, hardness and blank condition are checked before production. The machining instructions identify which mounting face acts as the primary reference rather than treating both legs as independent parts.
The first bracket is checked by CMM for face relationships, angles and hole locations. In-process sampling follows features affected by reclamping or cutter wear, and any setup adjustment is verified before the next production pieces proceed.
All finished brackets receive an appearance and key-dimension inspection before packing. Inspection records identify the drawing revision and production lot; third-party inspection is supported for the completed order.
