When tolerances matter, you need more than just a general machine shop – you need a CNC machining partner with experience, traceability, and engineering input.
At Fowler & Holden, our machining department complements our foundry by offering full-service post-casting and precision machining in Grimsby. Whether you’re a buyer, specifier, or project manager, here’s what to expect when requesting a machining quote.
