CNC Machining of Aluminium Extrusions

Subcontract cnc machining services

Our comprehensive cnc machining and fabrication facilities enable Capalex to convert raw lengths of aluminium extrusion up to 7.6 metres long into your specified component parts. Machining of aluminium extrusion involves one or more of the following processes.

Sawing

We have an extensive range of saws which means we can use the right saw for your required size of extrusion, giving you the quality of cut and tolerances you require. Our automated and manual saws can cut a vast range of extrusion profile sizes and lengths and also produce angular mitre cuts.

Manual Saw

CNC Machining and Milling

Our modern range of specialised CNC machines for aluminium extrusions have the capability to efficiently manufacture complex or simple machined detail you require for your extruded products. Utilising our lean manufacturing techniques and our advanced jigging design we can quickly produce your extruded aluminium components in any quantity and to the accuracy required.

Punching

Aluminium extrusions can be punched efficiently where larger volumes can justify the punch tooling cost. Capalex has a range of single and multi headed punching facilities suitable for a broad range of extrusion profile sizes and lengths. We utilize lean manufacturing techniques to maximize punching efficiencies.

Conventional drilling, tapping milling and turning

In addition to our high-speed modern cnc machines, Capalex also has older convectional machines, which are ideal for one-off or very low prototype quantities. We can quickly machine your new designs for evaluation, before manufacture of production quantities.

Deburring

Burrs created during the sawing and machining processes can be removed, if necessary, to produce a cleanly finished component. Capalex has various methods of deburring available, but mechanical brushing or tumbling are generally the preferred processes to achieve the desired finish.

A machined extruded aluminium component can be surface treated to your specification. We are able to assemble with any companion parts and pack and label to your requirements ready for you to send straight to your customer.

Capalex manufacturing can also offer a subcontract cnc machining service if you have aluminium or steel from another source that requires machining.
