3. Development of Direct Drive Abrasive Cut-off Machine
AMTDC (IIT-Madras) team: S. Akash, R. Srikanth, N. Ramesh Babu
Industry Partner: Chennai Metco Private Limited, Chennai
Project Highlights
The indigenous development of high-power large-scale direct drive abrasive cutting
machine by AMTDC is a new addition to the existing small-scale direct drive cutters in India. A
high power, high quality fully automatic cutting machine suitable for 300 mm to 500 mm cut-
off wheels with the capacity to cut solid sections up to 150 mm in diameter is developed
successfully with the newest technologies for fast cutting and deformation-free specimen
surfaces. As the spindle is directly driven by the motor, the entire motor power is available for
cutting thus enhancing the cutting efficiency of the system by 40% over that compared to
belt-driven spindles. The developed technology using higher stiffness spindle and flexible pin-
type coupling ensures minimized deflection of spindle
during cutting and vibration free generation of surfaces thereby reducing chatter and burn
marks. This heavy duty, precisely manufactured machine offering efficient, versatile and high-
quality cutting, is useful for cutting of samples from large sized castings and forgings such as
engine blocks, wheel hubs, brake drums, etc. This abrasive cutter's large workspace and simple
design also enables rapid sectioning of samples. The machine has huge market potential in
automotive, aerospace, defense sectors and is required by several entities like CVRDE, BHEL,
BARC, and other metallurgical labs. The price of the developed machine is expected to be 40%
lower than imported machines.
Current Status
The machine developed under this project was exhibited in EMO 2017 (Germany),
EEPC IESS 2018 (Chennai) and was exhibited in recently concluded IMTEX 2019, Bangalore.
The project is completed in terms of its deliverables. Testing and characterization are
underway to take the machine to next level.
