Discover More About Us...
We can turn components from 1mm to 20mm in diameter.
Bon Precision Engineering is centrally located in Thrapston, Northamptonshire, with good links to the M1, A14 and M11. We manufacture all our CNC turned components from our HQ. We welcome visitors—and the kettle is always on!
Of course! The only thing we ask is that you provide a covering order for any CNC machining we do. Often, we can give a more competitive price as well.
We are very flexible with our lead times and will always strive to help when time is tight. Our standard lead time is 2-3 weeks, but we can often better this date, depending on the complexity and quantity of the CNC turned parts ordered.
