CNC Machined Parts for Industrial Machinery

Replacement parts, jigs, fixtures, shafts and wear components for machines that are already running on a factory floor. Send a drawing, a sketch with dimensions, or the worn part itself.

The three we hear most

Problems buyers bring us in this sector

Maintenance and machine-building work arrives in a hurry and usually without a complete drawing. These three problems come up every week.

“The machine is down and the original supplier is gone”

Send photographs with a ruler in the frame first. If we need the part, post it: we measure it on the CMM, draw it, send you the drawing to approve, then cut. The drawing stays yours for the next time.

“Nobody will make just one”

We will. There is no minimum order — one replacement part is a normal order here, quoted in 16 hours like anything else.

“The replacement wore out faster than the original”

Usually material or hardness, not machining. Tell us how the part failed and we will suggest a material and heat treatment rather than copy a part that did not last — wear parts are cut on wire EDM after hardening so the profile cannot move.

Typical parts

What we machine for machine builders and maintenance teams

Half of this work is reverse-engineered: an obsolete part fails, the original supplier is gone, and someone needs it made. We are set up for exactly that — no minimum order, and one part is a normal order here.

Replacement and spare parts

Obsolete components remade from a drawing, a sketch, or the broken part measured on our CMM.

Shafts, bushings and spacers

Turned parts in steel, stainless and bronze, ground finish where the drawing calls for it.

Jigs and fixtures

Workholding, locating nests and assembly fixtures built to your datum scheme.

Wear components

Guides, wear plates, gibs and slides in hardened tool steel, cut on wire EDM after heat treatment.

Gears, sprockets and cams

Profiles cut on wire EDM straight from plate, tooth form held to the drawing.

Machine guards and panels

Sheet-metal guards, brackets and covers, powder coated to your colour.

Materials and finishes

What these parts are usually made from

Tool steel and 4140 where the part wears, stainless where it is washed down, bronze and POM where it slides.

Typical requirements

Fits, hardness and the dimension nobody wrote down

Replacement parts usually arrive with an incomplete drawing. We measure what you send, write down what we find, and confirm the fits with you before cutting — because the bore that has to press onto a shaft matters more than the ten dimensions around it.

Questions

What buyers in this industry ask

I do not have a drawing, only the broken part. Can you still quote?
Yes. Send photographs with a ruler or caliper in the frame for a first look, and we will tell you whether we need the part itself. If you post it to us we measure it on the CMM, produce a drawing, send it to you for approval, and only then cut. The drawing stays yours.
Can you make just one?
Yes. There is no minimum order. A single replacement part costs more per piece than fifty, obviously, but we quote and machine one-offs every week and there is no surcharge for the privilege.
Can you harden the part as well?
Yes. Heat treatment is arranged through us and comes back on the same invoice. For anything that must hold its profile after hardening, we cut the profile on wire EDM after heat treatment so it cannot move.
