Capability
Turned and milled components for prototype, low-volume and repeat production — with the process route, datums and inspection points decided before the machine is loaded.
Best for
Drawings that need planning, not just cutting time
You send
2D drawing, 3D model where available, material and quantity
You get back
Machined parts inspected against the drawing
How it starts
Feasibility confirmed at review rather than guessed
The situation
Plenty of shops will quote a machined part. Fewer will read the drawing carefully enough to ask the question that saves you a scrapped batch.
What you get
Turning and machining capability described by technical envelope and application, not generic claims.
Ambiguities in datums, tolerances or finish are raised with you at review, not discovered during machining.
Grinding is in-house; heat treatment, plating and coating are coordinated so you receive a completed component.
A prototype can move to a repeat batch without re-engineering the job.
In-process checks confirm critical features before the next operation; final inspection confirms the drawing.
Where this stops
Machine working envelopes are published on the infrastructure page as they are verified. If your part is near the limit, send the drawing and we will confirm feasibility rather than guess.
CNC turning covers shafts, sleeves, bushes, flanges, adaptors and holder bodies. VMC machining covers plates, brackets, housings, fixture elements, and the milled features on turned parts — keyways, flats, cross holes and tapped holes.
Carbon steels, alloy steels, case-hardening steels, stainless steels, cast iron, aluminium and brass are machined regularly. Exotic and hardened materials are reviewed case by case, with the tooling and process route decided before quotation rather than discovered during it.
Programmes and setups are retained so a prototype can move to a repeat batch without re-engineering. Low-volume production for machine builders and automation companies — where each order is a handful of parts across many part numbers — is a normal pattern of work here, not an inconvenience.
Grinding is handled within CMTA. Heat treatment, plating, blackening and coating are coordinated through approved partners, with CMTA controlling the sequence, the allowances and the final inspection. You receive a finished part rather than a machined blank and a list of phone numbers.
How it runs
Each stage produces something you can check, and the drawing approval stage is yours to control.
Feasibility, datums, tolerances and secondary operations assessed.
Operations, allowances and inspection points defined for the quantity.
CNC turning and VMC work, with in-process verification.
Coordinated treatments, final inspection, protective packing.

FAQ
The questions engineers and buyers ask before sending a drawing. If yours is not here, ask it directly — you will get an engineer's answer, not a brochure.
Still have a question?
Talk to Anita M.N, Managing Partner, or send the drawing and let the review answer it.
A drawing with tolerances, the material, the quantity and the delivery target. A 3D model helps for milled parts. Tell us about secondary operations so they can be planned into the route rather than bolted on afterwards.
Yes, and the programme and setup are kept so repeat orders do not start from scratch.
Machining, grinding, assembly and inspection are CMTA's own work. Where machining needs heat treatment, plating or coating, those are coordinated through approved partners and CMTA stays responsible for the finished part. The exact split for your job is confirmed in writing at feasibility review, not left vague.
Before manufacture, we list the dimensions, fits, finish and functional checks that actually decide whether the part works. Those are what get measured, reported and, where relevant, trialled on your machine. Acceptance is judged against that written list rather than a general assurance.
