Capability
Every shop has an operation that runs badly because the available holder was never designed for it. CMTA designs and manufactures the holder that operation actually requires — and proves it on your machine before you commit to more.
Best for
Operations where no standard holder fits, reaches or holds well enough
You send
A photo of the setup, the machine interface and what is going wrong
You get back
A concept, an approved drawing, then a trialled holder
How it starts
Technical review, usually within one working day
The situation
A custom holder is justified more often than most shops assume — usually the moment someone starts working around the tooling instead of with it.
What you get
Purpose-designed holders for reach, interference, compatibility, cost and performance problems.
You see the proposed interface, geometry, clamping and reach on a drawing and can check it against your machine and fixture before committing.
New designs are made as a single piece first and run on your machine, so any refinement happens before you buy a set.
Feedback is written back into the drawing and the released revision is what every subsequent holder is made to.
Where reach and rigidity conflict, we tell you and propose the best balance instead of promising both.
Where this stops
A custom holder cannot fix a worn spindle, a poorly located fixture or an unstable workpiece. If the review points at one of those, we will say so rather than sell you a holder that will not help.
We ask what you are machining, on which machine, with which tool, and what is going wrong or what you want to improve. Photographs of the setup, a marked-up drawing or a short video of the cut tell us more at this stage than a formal specification does.
That discovery is the difference between a holder that matches a drawing and a holder that fixes a problem.
From the discovery inputs CMTA proposes a concept with the interface, body geometry, tool clamping and reach defined. You receive a drawing or model to check against your machine and fixture. Changes are agreed on the drawing, and manufacture starts only after written approval of the final revision — so nobody discovers a clearance problem in steel.
We size the body section for the cutting loads, minimise unsupported length, keep the tool location concentric and repeatable, and check that the geometry is sensible at the speeds involved. Reach and rigidity pull against each other; where they conflict we say so and propose the best trade-off rather than promising both and disappointing you later.
For a new design, one holder is normally made and trialled on your machine. Fit, finish and cycle-time feedback is captured, refinements are made to the drawing, and the final revision is released for repeat quantities so every subsequent holder matches the one that actually worked.
Many custom holder projects start as a localisation exercise: an imported holder that costs too much or takes too long to replace. CMTA reverse engineers it from a sample, confirms the interface and tool fit, and manufactures it here — with the option to correct a weak point in the original design rather than faithfully reproducing a flaw.
Automotive and auto-component machining lines, machine tool builders fitting out new machines, aerospace sub-tier shops with awkward geometries, and general engineering companies with one-off jobs that would otherwise be refused.
How it runs
Each stage produces something you can check, and the drawing approval stage is yours to control.
What you are machining, on which machine, with what tool, and what is going wrong.
Interface, body geometry, clamping and reach proposed with the trade-offs stated.
Drawing or model issued; manufacture starts only after written sign-off.
One holder made, run on your machine, refined if needed, then 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 application, machine interface, tool or cutter, reach and clearance constraints, and the result you want. A photograph of the current setup and a marked-up drawing are the fastest way to start; formal specifications can follow during the review.
Yes — and for a new design that is exactly how it should start. One holder is made, trialled on your machine and refined before any repeat quantity is released.
Machining, grinding, assembly and inspection are CMTA's own work. Where custom tool holder 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.
