High Precision CNC Machining
Thompson Precision are set up to produce complex parts with an ultra-high level of precision. We offer this service for both small and large components, which are produced through CNC milling and CNC turning in a wide range of metals and plastics.
We place a great emphasis on maintaining the highest levels of quality and precision. We have a temperature-controlled Inspection Department that is equipped with a brand-new large format Hexagon Metrology Status CMM (CNC Co-ordinate Measuring Machine), running PC-DMIS software. This machine allows us to maintain and warrant the highest levels of quality and precision. We are able to offer fully automatic checking and reporting, as well as F.A.I.R’s (First Article Inspection Reports) in any format required for components up to 1600 mm x 900 mm x 800 mm.

Just a quick note to thank you for the big plate you manufactured for me. It all fitted perfectly, and it would have been a disaster for me if it hadn’t been correct or delivered late.

Case Studies
CNC Machining of Large Hydraulic Manifold
The client required a large hydraulic manifold to be machined from a block of aluminium 1100 x 600 x 400mm. With the manifold needing to be machined to a high tolerance required by the client.
Electronics Enclosure
This case study was from a client who was very specific about the requirements for this electronics enclosure for the exact positional tolerances. It was a challenging job & one we completed to perfection.
High Precision Aerospace Fixture
The case study for this job was for an aerospace part that was no longer available to purchase. We had limited information to go on, but once again we finished this job to a very high standard.
Mechanical Prototyping of a Fishing Reel
The client for this case study had a new fishing reel concept that they wanted us to manufacturer so they could test it out before taking the design further.
