About Millbrook
A heavy engineering machine shop in Clay Cross
Millbrook Precision Engineering machines medium to large parts for industry from Derby Road, Clay Cross, a short drive from junction 29 of the M1.

History
Founded 2001, with roots in 1803
Millbrook was founded in 2001, when the machine shop of Bryan Donkin Co. Limited of Chesterfield and its machinists moved across to form a new company. That team brought with it a way of working whose roots run back to 1803, when Bryan Donkin opened his engineering works in Bermondsey, London: more than 220 years of continuous engineering expertise, and more than 120 of them in Chesterfield.
The shop
The shop is laid out for large work: 10 t and 5 t overhead cranes, CNC horizontal borers with travels to X 3,000 mm, four CNC vertical lathes turning to Ø2,134 mm, double-column and vertical machining centres, a large manual borer and a Faro portable arm for inspection. See the full machine list.
