Flat-bed CNC Lathes

Model	AC-1840/1860/1880
Spindle Bore	56mm(2")
Height of Centers	225 X 1000/1500/2000 mm
Spindle speeds	H: 3100 - 681 rpm M: 680 - 151 rpm L: 150 - 30 rpm

This entirely new design places the emphasis firmly on multi-performance, safety,
low noise, advance productivity and easier operation

	FAGOR Control is standard, but ANILAM, FANUC & SIEMENS on request.
	Spindle auto speed shifting (3 steps) and CNC controlling
	All casting are made of high tensile meehanite cast iron which are annealed treatment to eliminate internal residual stress
	Wide bed and box constructed, bed ways are high frequency heat treated, precision ground etc.,to provide stability at high speed running or deep cut
	Spindle & gear are made of CR-MO alloy steel which are carburizing & precisely ground, forced lubricating & oil bathed combined in headstock which can be prolonged servicinglife
	Three point support on the spindle with two taper roller bearings and one roller bearing to assure the accuracy & rigidity.
	AC-1800 series with hi-spindle speed 3100rpm
	All gap bed
	AC main drive spindle motor
	High precision ball screw
	CSS available
	Heavy duty tailstock
	V-8 turret tool post on request
	Electric 4-Way tool post on request
	External spindle cooling system on request
	Tailstock spindle dia 68mm
