JET GH-1880ZX MANUAL LATHE

Technical Description

The JET GH-1880ZX is a precision geared-head lathe engineered for heavy-duty metalworking applications. Featuring an 18-inch swing over bed and 80-inch distance between centers, this machine accommodates substantial workpieces with a 3-1/8-inch spindle bore supported by two tapered and one ball bearing for superior rigidity and accuracy. The robust 7.5 HP, three-phase motor delivers 12 selectable spindle speeds ranging from 25 to 1,800 RPM, enabling optimal performance across diverse materials and operations. The lathe provides 46 longitudinal and 31 cross-feed rates, with ranges of 0.0015–0.0900 IPR and 0.0006–0.0360 IPR respectively, supporting precision threading in 61 inch and 24 metric thread pitches. The 11-inch swing over the cross slide, combined with 74-5/16-inch carriage travel, facilitates extended workpiece manipulation. A one-piece cast-iron base with ANSI Class 50 wear-resistant bed ways absorbs vibration, enabling heavier cuts with enhanced stability. The D1-8 spindle mount accepts MT-7 (MT-5) taper tooling, while the removable gap accommodates large-diameter work. Standard equipment includes a 10-inch three-jaw scroll chuck, taper attachment, collet closer, follow rest, and automatic carriage stop. Measuring 136 × 44 × 66 inches and weighing 6,590 pounds, this machine provides industrial-grade precision, efficiency, and reliability for comprehensive metal fabrication operations.
