J & W GH1340Z MANUAL LATHE

Technical Description

The J & W GH1340Z is a precision manual engine lathe designed for versatile metalworking applications in manufacturing and toolroom environments. This machine features a 13-inch swing over bed, enabling operators to work with cylindrical components up to that diameter. The lathe accommodates workpieces up to 39.4 inches between centers, providing substantial capacity for medium-sized production runs and single-part machining. With a 1.5-inch spindle bore and maximum spindle speed of 2,000 RPM, the GH1340Z handles diverse turning operations including cylindrical surfaces, tapered profiles, threading, drilling, and reaming. The 7.3-inch swing over the cross slide allows clearance for internal machining operations. The machine incorporates a robust cast iron bed construction with precision-ground guide surfaces, ensuring dimensional accuracy and durability. Threading capabilities include metric threads ranging from 0.45 to 7.5mm pitch and inch threads from 4 to 112 TPI, accommodating both standard and specialized fastening requirements. The lathe is equipped with centrally-driven speed-changing mechanisms for easy operation and maintenance, along with adjustable mounting feet for proper leveling and foundation installation. Safety features include an emergency stop button and protective mechanisms. The machine dimensions span 76.4 inches in length by 29.7 inches in width with a height of 48.8 inches, weighing approximately 1,345 pounds. This makes it suitable for job shops, educational institutions, and small to medium manufacturing facilities requiring reliable, precision manual lathe capabilities.
