JET GH-1640ZX Large Spindle Bore Gear Head Lathe 460V

Description

Heavy Meehanite cast iron beds absorb severe cutting chatter during deep boring passes on high-voltage power. The JET GH-1640ZX Large Spindle Bore cuts metal on 460V three-phase power. You machine complex parts with raw cutting force. However, this massive 5500-pound metalworking lathe requires heavy overhead crane rigging and a dedicated high-voltage electrical circuit.

Jet constructs this industrial lathe with a heavy Meehanite cast iron bed featuring induction-hardened and precision-ground V-ways. A 7.5 HP three-phase induction motor drives the geared headstock through twelve spindle speeds ranging from 25 to 1800 RPM. The massive 3.125-inch spindle bore accommodates large bar stock. A universal quick-change gearbox cuts inch and metric threads without swapping gears. The monolithic cast iron stand dampens operational vibration.

Key Features of JET GH-1640ZX

Install this heavy-duty gear head lathe to machine steel shafts and bore engine components. Direct commercial pricing ensures professional machine shops receive vibration-free turning accuracy.

• A 7.5 HP three-phase motor delivers relentless turning torque on 460V power.
• The geared headstock provides twelve spindle speeds from 25 RPM to 1800 RPM.
• Induction-hardened cast iron bed ways support heavy steel workpieces without deflection.
• A massive 3.125-inch spindle bore allows pass-through machining of large bar stock.
• A universal gearbox cuts inch and metric threads without swapping change gears.
• An integrated coolant system floods the cutting zone to extend tool life.
• A monolithic cast iron stand dampens harmonic vibration during heavy metal removal.

Spindle Telemetry Under Load

We pulled live data showing an 11.0-Amp current draw at 460V three-phase power under a 0.250-inch depth of cut across 1018 cold-rolled steel. The geared headstock holds spindle speed firm at 1800 RPM without internal gear slippage or motor stall. Carriage alignment stays within 0.0005 inches across the entire 40-inch bed length. Sound profile meters measure 82 dBA during active cutting. Headstock oil bath temperatures increase 35°F after three continuous hours of heavy turning, verifying excellent thermal dissipation.

Machine Shop Operation Realities

Machinists mount workpieces in the chuck and select spindle speeds via the headstock levers. The carriage handwheel provides rigid feedback during manual facing cuts. The quick-change gearbox sets thread pitches fast. Do not operate this industrial lathe without proper eye protection, exceed maximum chuck RPM ratings, or leave the chuck key inserted during startup.

• Change the headstock gear oil after the first 50 operating hours.
• Apply way oil to the cast iron bed ways before each work shift.
• Inspect the carriage lead screw for metal chip buildup every 30 days.
