Precision Machining
Rank Brothers has been carrying out precision engineering for companies in the Cambridge area and beyond for many years. We specialise in CNC turning and CNC milling of prototype parts and small runs with fast turnarounds, however, we are happy to quote for larger jobs too.
If you require milling or turning then Rank Brothers are able to manufacture a part from your model and drawing using our CNC mills and CNC lathe. Our CAM software can open models in most common formats and for simpler parts we can manually program our CNC machines from your drawings alone.
In addition to our manufacturing equipment we also have a coordinate-measuring machine that can provide highly-accurate measurements of your parts.
