Solution
The machine still has years of work in it. One component failed and nobody makes it any more. That is a solvable engineering problem, not a reason to write off a machine.
Best for
Mechanical parts the OEM has discontinued or cannot supply in time
You send
The failed part or photographs, plus the machine and its function
You get back
An approved drawing and a verified replacement
How it starts
Feasibility and confidence assessed before you commit
The situation
A worn sleeve, a broken shaft, a cracked holder or a stripped spindle component takes the whole machine out. Each week of waiting usually costs more than the part ever did.
What you get
Recreate parts the OEM no longer supplies, from sample to verified replacement.
We assess the sample, say which surfaces can be trusted and which must be reconstructed, and give you a confidence level and a timeline.
The approved drawing becomes the controlled document for this and every future order, so the next failure is a reorder.
The replacement is inspected against the drawing and, where practical, fitted or trialled on the machine.
If the failure history points at a design or material problem, we propose the fix rather than faithfully reproducing the fault.
Where this stops
This route covers mechanical components: shafts, sleeves, bushes, gears, holders, adaptors, slides and fixture elements. Electrical and control parts are outside scope unless they are purely mechanical carriers.
The sample is examined for the surfaces that can be trusted and those that must be reconstructed from function. Material and hardness are tested where necessary. You receive a feasibility view, a confidence statement and a realistic timeline before committing — including, occasionally, the news that a particular part is not a good reverse-engineering candidate.
The replacement is accepted against the approved drawing and, where practical, a fitment or trial on the machine. The drawing then belongs to you and can be reordered against without starting the process again.
How it runs
Each stage produces something you can check, and the drawing approval stage is yours to control.
Sample condition reviewed; feasibility, confidence and timeline stated.
Dimensions and function analysed, drawing issued for your approval.
Machining, coordinated treatment and grinding to the approved drawing.
Inspected against the drawing, then fitted or trialled on the machine.

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.
That is the normal starting point. The part is measured and analysed from the sample, and a drawing is developed for your approval before manufacture.
Yes. Tell us the machine is down and the feasibility review is prioritised. You will get a realistic timeline rather than an optimistic one.
Dimensionally it is made to the approved drawing. Material and treatment are selected to perform the function and may differ from an unknown original — which is stated clearly on the drawing rather than glossed over.
Often, yes. If the failure history points to a design or material weakness, CMTA proposes an improvement on the drawing for your approval.
