From aluminium brackets to titanium fittings.
Cutting data, tooling and fixturing are set per material and per feature — not by a house default.

Aluminium alloys
Lightweight brackets, housings and structural parts
6061, 7075 and cast plate. High-speed strategies with through-tool air or coolant.
Titanium alloys
High-strength, high-temperature aerospace and defence components
Low surface speed, heavy flood coolant and rigid fixturing to control heat and chatter.
Stainless steels
Corrosion-resistant fittings, fluid-system and marine parts
303, 304 and 316. Sharp geometry and controlled feed to avoid work-hardening.
Alloy and carbon steels
High-load shafts, gears and structural fittings
EN8, EN24 and equivalents. Roughing and finishing split to hold post-stress geometry.
Tool steels
Jigs, fixtures, gauges and tooling components
Machined soft where possible, with allowance planned for heat treatment movement.
Copper alloys
Fittings, bushes, electrical and fluid-system parts
Brass and bronze. Polished tooling to keep gummy materials from smearing the finish.
Polycarbonate & engineering plastics
Transparent covers, guards and lightweight non-metallic components
Single-flute tooling and vacuum or low-clamp fixturing to avoid crazing and distortion.
Material traceability maintained on every order · certificates supplied on request
Three things that decide whether a tolerance is realistic.
Material stability
Stock that carries residual stress will move when you cut it. On thin or asymmetric parts we split roughing and finishing, and allow the part to relax in between.
Wall thickness and access
A thin wall or a deep pocket sets the tool reach, and tool reach sets the achievable tolerance. Tell us the critical features early and we will advise on the geometry.
How it will be measured
A tolerance is only meaningful against a stated datum scheme. We agree the inspection method — CMM or vision — at the quotation stage, not after machining.
Not sure the material is machinable to your tolerance?
Send the drawing and the specification. We will tell you what is achievable, what needs a design tweak, and how we would inspect it.
