Custom Metal Brackets

Custom mounting brackets connect the component to its supporting structure. The useful starting point is the interface: what attaches, where it locates and which direction needs adjustment.

Machined blocks and slotted mounts for positioning a sensor relative to a target or fixture. Specify the sensor interface, adjustment direction and fastening arrangement. Where location must be repeatable, identify the locating features separately from the clearance holes and adjustment slots.

Right-angle mounts, adapter plates and offset supports for equipment cameras. Mating-face orientation, hole pattern and access for screws determine the geometry. Include any required adjustment range and the space needed around the camera, lens and connectors in the assembly information.

Mounting feet and multi-face supports connecting an actuator or end-effector interface to the machine. The drawing defines bores, fastener patterns and reference faces. Load direction, unsupported length and allowable movement help define the design requirements; the machined part is supplied to the agreed design.

The manufacturing route should follow the interfaces and quantity. A custom bracket does not always need machining from solid stock.

A standard bracket is worth considering when its hole pattern, envelope, material and adjustment range already meet the assembly requirements. This page covers drawing-based manufacture; it is not a stocked hardware catalogue.

Simple L, U or offset shapes in sheet material may suit cutting and bending. Sheet thickness, bend direction, internal radius and hole positions relative to bends belong in the specification. Great Machining supports this route through selected manufacturing partners.

CNC machining suits thick sections, pockets, machined locating faces, threaded features and mounting details in several directions. Geometry, tool access and inspection requirements determine whether we use three-axis or five-axis machining.

A useful bracket drawing separates assembly clearance from the features that control position. It also identifies the relationships between mounting faces, rather than applying the tightest tolerance everywhere.

Show the slot direction, usable adjustment range, fastener size and any counterbore or countersink. Mark locating bores or dowel holes separately. A hole-size tolerance and a position tolerance answer different questions: whether the mating feature fits, and where its axis lies relative to the drawing datums.

Identify the faces that contact the equipment and the reference used for the mounting angle. State flatness, perpendicularity or angular requirements on the relevant features when needed. Keep screw-head, tool and connector clearance in the assembly model so the bracket can be installed in its intended position.

Stiffness depends on the bracket geometry and how it is supported and loaded. If movement matters, include the load direction, support spacing and allowable displacement in the requirements. Material grade alone does not establish bracket stiffness or a safe load rating. Relief pockets, thin sections and internal radii are reviewed for machining access and support.

Material choice includes the grade, temper and stock form. Finish requirements then need to preserve the holes and contact faces that matter to the assembly.

6061-T6 and 6082-T6 plate or bar are options for machined aluminium brackets; the specified standard and temper remain part of the order. They are not automatic substitutes. 7075-T6 is available for designs that specify it, including the multi-face project above. See Aluminium CNC machining for the material route.

Steel mounting parts are quoted to the specified grade and hardness condition, with heat treatment and surface protection identified where needed. Stainless options include 303, 304 and 316L, selected for the drawing and environment. These grades are not interchangeable; welding, corrosion requirements and finishing affect the choice.

For a partner-produced sheet bracket, 5052-H32 aluminium is a separate material and process choice from a 6061-T6 or 6082-T6 machined component. Confirm thickness, bend geometry and final coating with the proposed route. A similar outline does not make the two constructions equivalent.

As-machined, deburred parts retain machining marks. Specialist anodising, plating, passivation and other compatible finishes are arranged with production partners. Identify critical holes, threads, contact faces and any electrical grounding areas that need masking. Agree whether dimensional acceptance applies before or after finishing; coating thickness is not a universal conversion to the dimensional change of every feature.

Our in-house dimensional inspection follows the agreed features and inspection plan. First-piece, in-process and final checks connect the drawing revision to the supplied parts.

The plan distinguishes hole diameter from datum-based position and relates each requirement to a suitable method. CMM measurement can support coordinate dimensions and GD&T within its applicable range; probe access, setup and measurement conditions must suit the feature.

Mounting-face geometry, thread requirements and relevant finished dimensions are checked as ordered. Specify the thread standard, tolerance class and effective depth. Appearance areas and deburring requirements are agreed alongside the dimensional requirements, especially where a bracket sits near cables or mating surfaces.

Critical-dimension reports can be included in the quotation. Full-dimension, per-part inspection and formal first-article documentation are separate scopes. Labels and packing records identify the part number, revision, quantity and applicable batch. Explore Quality control and inspection for methods and document options.

We clarify the material, critical interfaces and manufacturing route before confirming the quotation. Production follows the approved revision and agreed inspection requirements; specialist finishing is included where specified.

For subsequent batches, confirm the drawing revision and any changes to material, finish or documentation. Revised hole patterns and mounting angles need to be carried through the manufacturing and inspection requirements. Parts are packed and labelled to keep the ordered versions identifiable.

Simple aluminium CNC prototypes typically take 5–7 working days for 1–10 parts in normally stocked material, with conventional tolerances and deburring. Complex or multi-face prototypes typically take 8–12 working days for 5–20 parts; special-material procurement and heat treatment are scheduled separately. Manufacturing time follows the confirmed production calendar and starts once files, technical requirements, order conditions, any required payment and material availability are confirmed. Specialist finishes, customer approvals, drawing changes, international transport and customs add time. Your quotation confirms the schedule for the actual order.

Start with the part file or a useful description, intended use and quantity. Grade and temper, critical holes and datums, finish, required reports and delivery country help refine the quotation. Great Machining will confirm the manufacturing route and agreed deliverables for your design.

For confidential designs, enquire without attachments first so we can agree an NDA and file-transfer arrangements. The current quote form accepts non-confidential files.
