To match demand of greater accuracy & total reliability at higher speeds Jyoti CNC has developed Performance Series Vertical Machining Centers. The high dynamic structure supports rapid axis take-off with high accelerations. Broad rigid base with heavy cross ribbings with twin layer heavy column structure dampens effect of vibrations & balances whole machine while taking heavy cutting load with higher machining parameters. The machine has precision LM guide ways to support broad table movement with high load carrying capacity. This machines finds its place in applications where heavy material removal where direct machining required from castings and forgings. Most suitable for Dies and Moulds applications in injection moulding, investment castings, shell castings, forging dies, pressure die casting and pattern making.
