Every job that passes through The Machine Shop will have a dedicated CAD drawing, drafted by one of our team of trained engineers, to meet the specification requirements of the customer. After customer approval of the drawing, and any agreement on First Article Inspection samples, the job will be committed to The Machine Shop’s schedule.

The Machine Shop schedule planning is maintained with the Production Works Order system embedded in our operating system. After drawing approval is received, and the works order is raised, the customer will receive an indication of job completion dates based on machine loading. The Gateway operating system has live updates for Sales staff so that they can monitor the progress of Machine Shop jobs, and report any changes to schedules where appropriate. In some cases, capacity adjustments may be possible to expedite urgent customer requirements.

Substantial investment has been made in a wireless probing system that allows measurements to be taken in three dimensions with up to 0.001mm repeatability. The probing system is driven by our CNC system and provides customers with absolute measurements that they can rely on.

​

We are able to machine to the following tolerances:

• AL and inductance values down to +/-1%

• Dimensional values down to +/-0.005mm

• General Machining to +/- 0.05mm

The Machine Shop has developed exacting standards and test procedures to ensure everything that is shipped meets the specification outlined in the drawing.

We stock a large range of standard test coils which are all wound to ensure the full winding area is filled with 100 turns of wire; ensuring the winding is evenly distributed over the gap which increases test accuracy. As well as standard test coils, The Machine Shop can use customers test coils and test to their exact specification.

​

The Machine Shops standard test procedure is to sample batch test the finished cores to ensure the specification is met. The test results are electronically stored against the works order job and can be recalled at any stage. The Machine Shop can offer 100% testing and can also offer a First Article Inspections service, based on our own standard template or adjusted to match the customers test requirements.

During the machining process coolant is used to control temperature effects, reduce tool wear and control airborne particulates. After machining, the ferrite is often left with a deposit of ferrite sediment that needs to be removed. The ultrasonic cleaning bath is used to remove the ferrite sediment using environmentally friendly cleaning agents, and then the cores are air treated at room temperature prior to packaging. All ferrite cores are securely packaged in polystyrene shipping containers and/or secure vacuum packaging to avoid damage when in transit. Standard or customer bespoke labelling will then be affixed to the packaging and relevant test documentation will accompany each batch of material supplied.

Although often forgotten about, packaging is an important element of the process as this is what keeps your newly machined parts safe in transit. Parts are typically packed back into their original packaging, but this sometimes isn't possible with bespoke geometries. This is where custom packaging comes in! Our team are able to design packaging around your parts which are then precision cut using our laser cutter, creating a snug fit to help prevent breakages.
