Notes on Meet on Machine Tool Industry, Current scenario and the way forward:
Organised by Govt of India, HMT, IMMTA and CMTI.
- Jig boring machines are still imported from switzerland
- Only spare parts assembly is happening in India
- Imported components:
- Control system,
- drives
- ball screws
- turrets
- Systems in Inida have not reached Shoblin level accuracy
- Swiss jig boring machines are not mass produced. They are still hand crafted
- Huge market opportunity for
- ceramic manufacturing machines
- tape winding and polar winding machines
- FADEC controls are still imported
- CMTI is a R&D place for manufacturing of tools
TP Sridhar, ACE designers limited, Peenya, tps@acedesigners.co.in
- From 1979
- Largest turning center manufacturers
- 4000 installations per year
- 700 crore in turning ceters alone
- 1800 crore, 2000 employees
- Mostly Ex CMTI employees
- R&D under progress in
- hydrostatic guideways
- thermal compensation
- synthetic granite bed
- CNC controls
- sensors
- spindle bearings
- LM guides and Ball screws
- spinner lathe
- PSU should not put foreign items specs in RFQ
- Give advantages (20% cost) to Indian companies
L S Umesh, ACE manufacturing solutions
- Severe man power shortage in Industry
- Twin spindle vertical machining centers are exported to Mexico
P M Jadeja, CMD-Jyoti CNC, Rajkot
- 1000 crore technology company
- recently acquired french company
- Ball screws made by PMK
- Gives projects to IIT on machine tools
- ARCI Hyderabad develops powder for direct metal deposition, DMD
- CGCRI makes laser upto 1kW
ETA technologies
- etatechnology.in
- Makes friction welding machines
Bhagya Chandra Rao, Kennametal , Tumkur Road
- Originally Widma group
- 110 crore/year
- makes ECO grind machine tools and fixtures
- specializes in 5 axis CNC
- 38kW,12000 RPM spindles
- does vision based machining
- makes hydrostatic spindles and guide ways
- does turbine blade manufacturing using grinding process
- feels IISc doing research only for MNCs
- developing SV cam software for machining
Pragati Automation
- deepak@pragatiautomation.com
- makes tool turrets, automatic tool turrets and CNC machines
- CHINA is bigges customer
- uses ethercat real time communication
- servoand spindle drives of 0.75 to 15 kW
- makes ball screws
Sendhil Raja, RRCAT , under BARC/Atomic energy
- Does work on optics
- has laser and optical instrumentation laboratory
- does micro maching and liquid jet polishing, femto second laser micro machining
- optical precision required is 0.1 microns
- optical precision is usually of the order of wavelength/100
- grinding machines work on air bearings
- artificial granite/granitite being used
- reaction free air bearing spindles reduces forces transmitted to machining bed
- to reduce reaction force, usually opposing slides accelerating together are used.
- epoxy granite has similar rigidity compared to granite
- intra ocular lenses require diamond turning and 4000 diamond turning machines are required per year in India
Praful Shende, Kothari group, Pune
- Mr Amit Goradia does CNC controls and electropneumatics based CNC
- develops indigenous EPfast bus to talk between controller and drive
Other companies that came:
- Anant Jain, Micromatic grinding tech, develops hydrostatic grinding
- Vishal Nair, ISGEC, does metal forming press.
