Additional Info

The JET GH-1660ZX is built for shops that need extended turning length without sacrificing spindle capacity or horsepower.

With 60 inches between centers, a 3.15" spindle bore, and a 10HP 3-phase motor, this large spindle bore gear head lathe delivers the reach and torque required for longer shafts, rollers, hydraulic components, and heavy cylindrical parts.

The added bed length compared to 40" models expands job capability, allowing fabrication, MRO, and industrial repair shops to machine longer workpieces in a single setup — reducing repositioning time and improving accuracy across the entire part.

A D1-8 spindle nose supports heavy-duty workholding, while 12 spindle speeds (26–1500 RPM) provide the control needed for precision threading, deep boring, aggressive roughing, and finish turning.

The GH-1660ZX features a rigid one-piece cast iron base designed to dampen vibration and maintain alignment during heavy cuts. Larger stock can pass directly through the headstock, reducing cutoffs and secondary operations.

Extended 60" Between Centers Ideal for longer shafts, rollers, and cylindrical components — machine longer parts in one setup to improve alignment and reduce rework
10HP Industrial Power Delivers torque for aggressive roughing passes and heavy material removal while maintaining consistent cutting performance
3.15" Large Spindle Bore Allows larger diameter material to pass through the headstock, minimizing cutoffs and improving workflow efficiency
Rigid One-Piece Cast Iron Base Reduces vibration under load, supporting repeatable accuracy and improved surface finish during demanding applications
Built-In Certified Safety UL 987 Certified with standard electronic chuck key holder, foot brake, chuck guard, and lead screw cover for reinforced operator protection
Pre-Shipment Verified Performance JET’s 30-Point Inspection ensures controls, spindle accuracy, safety systems, and gear engagement are validated before delivery
