VMC Performance Large Series (T-BASE VMC)

To match greater accuracy with stability during high cutting condition for large size of components, Jyoti has developed Performance Large Series Vertical Machining Centers. Unique T-Base design and twin layer broad column structure sustains the vibrations & balances the machine against heavy cutting load and higher machining parameters. This machines finds its place in applications where heavy material removal where direct machining required from castings and forgings. The Series finds its application for injection moulding, investment castings, shell castings, forging dies, pressure die casting, pattern making and production work.
