ALEX-TECH MACHINERY INDUSTRIAL CO., LTD. - Precision Production Centers, CNC Turning Centers, YMS Series, Super Productive CNC Lathe, Teaching Lathe.

FEATURES

	45 °Slanted bed with integrated pipe structure gives super-rigid reaction force and prevents twisting and bending, in order to meet high precision requirement it allows close access for accurate machining and easy removal of chips.
	All of the casting we named at Meehanite casting. The internal stress was eliminated after anneal process to ensure the stability, and more rigidity.
	High accuracy of P4 class spindle bearings for ensuring precise turning under long time operation.
	12 positions hydraulic turret with quick tool changing of indexing (0.9 seconds) speed. For save the working time.
	High rigid hydraulic tailstock combined with the programmable movement, to reach precise rapid positioning. Lubrication monitoring system which could inspect oil leakage and lower pressure immediately.
	Harmonica appearance and color with brilliant look gives VT-20 lathe a state-of-art design.
