Product
Live centres carry the point on bearings so it rotates with the workpiece, allowing higher speeds and heavier loads without punishing the centre hole.
Best for
Long shafts and heavy work supported at speed
You send
Taper size, workpiece weight, speed range and accuracy needed
You get back
Centres rated for the load, with runout checked assembled
How it starts
Load rating matched to your actual application
The situation
Usually because they are asked to do a job one size up from the one they were bought for.
What you get
Bearing-supported centres for turning and grinding at speed.
The machine interface, tool interface and working envelope are checked before manufacture, so centres arrive ready to run.
Supplied from range where a standard suits the job, made to order where it does not, or reproduced from your sample where the original is unavailable.
Locating and clamping features are ground and the dimensions governing runout and repeatability are inspected before dispatch.
Repeat orders and modifications are handled in Bengaluru rather than through an import cycle.
A rotating centre carries the point on bearings so it turns with the work, allowing higher speeds and heavier loads than a dead centre without wearing the centre hole. CMTA manufactures live centres alongside dead centres and pipe centres.
Morse taper shanks in common sizes, standard and heavy-duty bearing arrangements, and interchangeable or extended points. Verified table to follow.
Choose the taper for the tailstock, the load rating for the workpiece weight and cutting forces, and the point form for the centre hole and clearance.
Hardened point and shank, precision bearings, ground taper and point, with runout checked on the assembled centre.

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.
Taper size, Workpiece weight and load, Speed range, Point geometry (standard, extended, pipe), Accuracy required. If you are unsure of any of these, send a photograph of the current holder and the machine nameplate — that is usually enough for us to confirm the rest.
Yes. Variations in length, reach, interface, clamping or tool size are manufactured to order. Fully custom variants go through the custom tool holder process, with a drawing approved by you before manufacture.
Against three things: the machine interface, the tool interface and the working envelope. Where an existing item is being replaced, matching it to your sample or original part number is the most reliable route of all.
Yes. A drawing is manufactured to its stated tolerances; a sample is measured and reverse engineered into a drawing for your approval, and then manufactured.
