Machining · Family run since 1946

The machines don't care how many you need.

3- and 5-axis milling and CNC turning, plus a shop of manual lathes, mills, drills, slotters, saws, balancers and undercutters - in aluminium, steel, stainless, brass, titanium and engineering plastics. The same machines and the same inspection whether the order is one part or a thousand - and the same people looking at it either way.

Quantity one is a real job. It always has been.

  • No minimum order
  • No account needed
  • A price within a day
  • Machined in our own Stoke-on-Trent workshop

The machines

CNC when it pays, by hand when it doesn't

You don't need to know which machine your part wants - that's our job. Turning is for round things, milling is for everything else, and a one-off repair is often quicker by hand than by program.

CNC

FANUC Robodrill

3-axis milling

The workhorse. A cutter working down onto a part clamped to the bed - plates, brackets, housings, manifolds. Most one-offs are this, and it's the cheapest way to get metal cut.

5-axis milling

The part tilts and rotates too, so five faces are cut in one setup - tighter tolerances, better surfaces, and no error creeping in from re-clamping.

CNC turning

The part spins instead of the tool - shafts, spacers, bushes, adaptors. Cross-drilling and flats on the same machine, so it comes off finished.

Manual

A long-bed lathe with its guard open, showing the chuck, carriage and tailstock.

Turning

Lathes

Facing, skimming, threading, sleeving a worn shaft. For one part, quicker than writing a program.

Milling

Milling machines

Flats, slots, pockets and squaring up stock - straightforward milling that doesn't need a toolpath.

A slotting machine, its ram standing above a rotary table.

Keyways

Slotters

Internal keyways and splines - the slot inside a gear or pulley bore that a mill can't reach.

A pillar drill with a machine vice on its table, beside a rack of bar stock.

Holes

Drills

Drilled, tapped, reamed and countersunk, on a part we've made or one you've brought in.

Cutting to length

Saws

Bar, tube and section cut to length - your stock or ours, before it goes on a machine.

A dynamic balancing machine with a rotor supported across its two pedestals.

Rotors & armatures

Balancers & undercutters

Dynamic balancing for rotors, fans and pulleys, and commutator undercutting for DC motor armatures.

Two machined inner pump rotors on a wooden bench, each with a keyway cut into its bore. The matching outer rotors, one lying flat and one stood on its edge showing the lobed bore.

Worth knowing

Why one part costs nearly as much as ten

People are often surprised by this, so it is worth saying plainly. Almost none of the cost of a machined part is the metal, and not much of it is the cutting either. It is the setting up - writing the toolpath, fixturing the part, proving the first one, checking it.

That work happens once whether you want one or fifty. So a single part carries all of it, and the tenth part costs a fraction of the first. This is why quantity breaks look so steep, and why we will often say "have two while we're set up" - the second one is genuinely cheap, and it saves the whole setup again in three years when the first one wears out.

It is also why we keep the model and the toolpath on file. The next one you order skips most of what you paid for the first.

Capabilities

The numbers, if you want them

And if none of this means anything to you, ignore it entirely and just tell us what the part has to do.

Process Envelope Typical tolerance Typical lead time
CNC milling, 3-axis 500 × 400 × 330 mm ±0.02 mm 5–8 working days
CNC milling, 5-axis 650 × 520 × 475 mm ±0.01 mm 7–10 working days
CNC turning Ø400 × 800 mm ±0.01 mm 4–7 working days
Aluminium Mild steel Stainless Tool steel Brass Bronze Titanium Cast iron Copper Inconel Acetal Nylon PTFE

Milling is on a DMG Mori DMU 50 five-axis - parts up to Ø630 × 600 mm and 300 kg - and a Fanuc Robodrill; turning is on a DMG Mori CLX 450 with a Y-axis for turn-mill work. Every part is inspected against its tolerances before it leaves, on a CMM where it calls for one, under a quality system certified to ISO 9001 by BSI.

Something outside these sizes? Ask anyway - we would much rather quote it than turn you away. Not sure metal is even the right answer? Print one first.

Talk to us

Describe it badly. We'll work it out.

You don't need a drawing, a company name or the right words for it. Tell us what the part does and what went wrong with the old one - that's usually plenty to get started.

  1. First Send us what you've got. STEP is ideal; a sketch or the broken original is fine.
  2. Then We'll come back with a price. Usually within a day, with any change that would make it cheaper.
  3. Finally We make it. Then post it out, or you collect it from the workshop.
