Case Studies - Heat Sink Cover

Deep slotted heat sink with multiple faceted faces made to customer supplied 3D model and key point drawing. Manufactured in aluminium 6082T651. We machined 6 components on a DMN650 machining center with a 2 week turnaround.

Job was for an existing blue chip company to which Paramount are a core supplier with a long and well established relationship. The job was competitively quoted for and won based on price and historic performance in quality and delivery. The job was initially being done by a company using a 5 axis machine but Paramount offered a manufacturing solution based on a 3 axis vertical mill with the added assurance of a higher quality of service. This was part of a larger package of work worth in excess of £60k.

Electronic model files were supplied in Step format accessed through a customer FTP portal which is a common project management requirement with many customers. Below can be seen Pro Engineer and EdgeCam screen shots of the programming operation. 

The job lent itself to be manufactured on a 5 axis machine, however, due to the capabilities of the Paramounts in-house CAM system we were able to produce the component on a 3 axis machine with an auxiliary fourth axis. This allowed for the machining of the complex curved surfaces using a bullnose cutter to achieve the correct curved surface in a single setup. The outside shape was machined first and then the slots cut. 

The component was inspected on the CMM using software to give a direct dimensional comparison to the original customer supplied model. With this particular customer we have a process approval for drawing free manufacture which stipulates that machining tolerances must be within +/-0.1mm all around unless otherwise stated on the drawing.

The component was then alocromed and stove enamelled to a Def-Stan using a local approved contractor, a process that was project managed by Paramount for quality assurance.
