45" X 400" ACRA MODEL 45400SGT PRECISION GAP BED HEAVY DUTY ENGINE LATHE

Headstock:
• The spindle is supported by high precision bearings suitable for both heavy and precision cutting.
• The speeds of spindle have 12 steps and designed on theoretical base. All gears and shafts are made of Ni-Cr-Mo steel and carbonize and ground.
• Control of main drive through electromagnetic brake, and automatic forced lubrication.
• Spindle Bore size selections- 153mm (6”), 230mm (9”), 255mm (10”), 310mm (12”), 355mm (14”), 405mm (16”), & 530mm (21”).

Gearbox:
• The Gear Box is entirely enclosed construction and provide a range of feedings or thread cuttings (inch, metric, module pitch and diametrical pitch).
• Inch and Metric threading without changing gears.
• Oil both lubrication and built in safety clutch safeguards the continuous and proper operation of the universal gear box.

Carriage and Apron:
• The Compound Rest can be fixed on the cross-slide anywhere, convenient for cutting work application.
• The Apron gives automatic lubrication and locked-safety device protects threads and feeding.
• Rapid traverse drive for longitudinal-cross feeding and forward & reverse feed operates very light and convenient.

Taper Attachment:
• The Taper Attachment is designed to easily operate and rapidly cut taper in high accuracy; the device can produce ± 10 angles.
• Electric cable in steel cover to protect wire from chips and prevent trouble with electric wires.
