Capability
A sound machine base with worn or outdated elements is often worth more restored than replaced. The assessment tells you which case you are in, before you spend on either.
Best for
Machines with a sound base and worn, outdated or unsafe elements
You send
Machine details, current problem, photographs and available downtime
You get back
An assessment, a scoped proposal, then modified and trialled equipment
How it starts
On-site assessment usually follows the first review
The situation
Retrofit versus replacement is a capital decision made with incomplete information more often than it should be.
What you get
Defined mechanical retrofit and modification projects, assessed honestly against replacement.
Structural condition, slide and spindle wear, alignment and the state of the elements you want changed — reported as what can be retained and what must be renewed.
Retrofit scope, cost and downtime set against the alternative of a new machine, so the decision is made on evidence.
The mechanical work is listed, and anything coordinated through partners — controls, drives — is named with its boundary of responsibility.
Drawings of new elements, spares identification and maintenance notes handed over at completion.
Where this stops
CMTA's scope is mechanical: structure, slides, spindles, tooling interfaces, fixtures and guarding. Control and drive retrofits are coordinated with partners and stated separately in the proposal.
A sound machine base with worn or outdated elements is often worth more restored than replaced — but not always. We help you compare the retrofit scope, cost and downtime against a new machine so the decision rests on evidence rather than on whichever option was proposed most confidently.
The machine is inspected for structural condition, slide and spindle wear, alignment and the state of the elements you want to change. The assessment defines what can be retained and what must be renewed, and current accuracy, output and safety condition are recorded as the baseline the retrofit will be measured against.
The scope lists the mechanical work: new spindles, slides, tooling interfaces, fixtures, guards, dedicated heads or workholding, together with anything coordinated through partners such as controls or drives. Boundaries of responsibility are explicit, because commissioning is the worst possible time to discover an assumption.
New elements are designed to fit the existing machine, manufactured and ground to the required accuracy, and integrated on site or at CMTA depending on the machine and your downtime window.
The modified machine is trialled against the acceptance criteria agreed at proposal stage, with results documented. Drawings of the new elements, spares identification and maintenance notes are handed over so the machine remains supportable long after the project closes.
How it runs
Each stage produces something you can check, and the drawing approval stage is yours to control.
Machine inspected; baseline accuracy, output and safety condition recorded.
Mechanical work defined, partner scope named, acceptance criteria agreed.
New elements designed to fit the existing machine, made and ground to required accuracy.
Fitted on site or at CMTA, trialled against the agreed criteria, documented.

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.
Machine details and condition, the problem or performance target, any drawings or manuals, photographs, site constraints and the acceptance criteria you expect. An on-site assessment usually follows.
Yes. The assessment sets retrofit scope, cost and downtime against replacement, and sometimes the honest answer is that the machine has reached the end of its economic life.
Machining, grinding, assembly and inspection are CMTA's own work. Where retrofit work 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.
