Capability
You have the part, or what is left of it, and nothing on paper. CMTA turns the sample into an approved drawing and a verified replacement — and the drawing stays with you, so the next time is straightforward.
Best for
Mechanical parts with no drawing, no supplier, or a long import lead time
You send
The sample or clear photographs with a scale, and what the part does
You get back
An approved drawing plus a verified replacement part
How it starts
Feasibility and confidence assessed before you commit
The situation
Reverse engineering is rarely a planned project. It is usually a machine that stopped and a supplier who cannot help.
What you get
Obsolete, imported and undocumented parts recreated from samples, with a drawing you keep.
We tell you which features were measured directly and which were reconstructed from function, so you can judge the risk before committing.
Dimensions, tolerances, material and treatment issued for your approval — and once approved, it is the document you reorder against.
The prototype is inspected against the drawing and fitted or trialled on the machine before the drawing is finally released.
If failure history points at a design or material weakness, we propose the correction rather than faithfully reproducing the fault.
Where this stops
Hardness can be tested and material inferred, but an unknown original specification is not always fully recoverable. Where we select a material by engineering judgement rather than test, the drawing says so explicitly.
A worn or broken sample can still be reverse engineered, but its condition determines how much must be inferred rather than measured. We assess the sample, identify the surfaces that can be trusted and those that must be reconstructed from function, and tell you what confidence to expect before you commit money to it.
Dimensions are measured, mating parts examined and the purpose of each feature understood. A bearing seat, a sliding fit and a clearance hole are measured to completely different tolerances because they do different jobs. Understanding the function is what turns a set of measurements into a drawing that will actually work.
Hardness can be tested and material grade inferred from the application and testing where required, but the exact original specification is not always recoverable. CMTA recommends a material and treatment that will perform the function, and states clearly on the drawing what has been verified and what has been selected by engineering judgement.
The output is a dimensioned drawing with tolerances, material and treatment, issued for your approval. Once approved it becomes the controlled document for this and every future order — which is the moment your dependence on the surviving sample ends.
The first part is manufactured, inspected against the drawing and fitted or trialled on the machine. Any correction is made to the drawing before final release, so repeat orders do not repeat the learning curve.
Machine tool spares for legacy HMT and imported machines, tool holders and adaptors, sleeves and bushes, spindle components and fixture elements — delivered as documented local alternatives with a drawing behind them.
How it runs
Each stage produces something you can check, and the drawing approval stage is yours to control.
Which surfaces can be trusted, which must be reconstructed, and how confident we can be.
Dimensions measured, mating parts examined, the function of each feature established.
Tolerances, material and treatment documented and issued to you.
First part manufactured, verified, trialled, then the final revision released.

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.
The sample or clear photographs with a scale, the machine and the part's function, its failure history, the quantity and the urgency. Mating parts or an assembly drawing improve accuracy considerably if you have them.
Worn surfaces are reconstructed from mating parts and function. We state which features were measured and which were reconstructed so you can judge the confidence for yourself.
Machining, grinding, assembly and inspection are CMTA's own work. Where reverse engineering 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.
