Product Details
Engineered for shops that value uptime and precision, the JET GH-1640ZX 16x40 Large Spindle Bore ZX Gear Head Lathe pairs a 16" swing capacity with a heavy geared-head drivetrain for consistent, repeatable cuts.
Long workpieces are no problem: the GH-1640ZX offers 40" between centers alongside a 3-1/8" spindle bore for feeding larger-diameter bar stock straight through the headstock.
A 10 HP, Three-Phase motor drives the geared head through 12 spindle speeds (26-1500 RPM), giving operators the torque and range needed for roughing, finishing, and threading in one machine.
This configuration of the GH-1640ZX adds a Acu-Rite 203 digital readout, giving the operator real-time positional feedback to cut setup time and reduce scrap, and a collet closer, which speeds up workholding changeovers and improves repeatability on small-diameter or bar-fed parts.
Standard industrial safety features include:
- Electronic chuck key holder to reduce the risk of a key left in the chuck
- Foot brake for rapid spindle stopping
- Chuck guard at the point of operation
- Full-length splash guard
- Lead screw cover to keep debris out of the drive mechanism
- Integrated coolant system
This machine ships only after inspection and is protected by JET's 2-year parts and labor warranty, giving shops long-term reliability and nationwide service support.
Shops in energy and oilfield equipment suppliers and industrial OEMs rely on the GH-1640ZX for consistent, repeatable turning work, as do large-scale repair facilities.
