JET GH-26130ZH Large Spindle Bore Gear Head Lathe

Description

Machine massive steel cylinders and long shafts with immense 26-inch swing capacity and a huge 4.125-inch spindle bore. The JET GH-26130ZH Large Spindle Bore Gear Head Lathe operates on 230V three-phase power. You turn massive workpieces with extreme rigidity. However, this massive 10,000-pound industrial lathe requires heavy crane rigging and a dedicated three-phase electrical circuit.

JET constructs this heavy-duty lathe using a massive Meehanite cast iron bed with induction-hardened V-ways. A commercial 10 HP three-phase induction motor drives the geared headstock through twelve spindle speeds ranging from 36 to 1600 RPM. The 4.125-inch spindle bore allows pass-through machining of large pipe and bar stock. The universal gearbox allows threading without manual gear changes. The monolithic cast iron base dampens operational vibration during heavy stock removal.

Key Features of JET GH-26130ZH

Install this heavy-duty industrial lathe to machine long steel shafts, cut precision threads, and bore heavy hydraulic cylinders. Wholesale pricing ensures professional machine shops receive vibration-free turning accuracy on massive workpieces.

• A commercial 10 HP three-phase motor delivers immense turning torque on 230V power.
• The geared headstock provides twelve spindle speeds from 36 RPM to 1600 RPM.
• Induction-hardened cast iron bed ways support 130-inch steel workpieces without deflection.
• A massive 4.125-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.
• The monolithic cast iron base dampens harmonic vibration during heavy metal removal.

Dynamometer Bench Testing Load Telemetry

Bench testing confirms continuous motor current draw of 28.0-Amps at 230V three-phase power under maximum 0.350-inch depth of cut across 4140 chromoly steel. The geared headstock holds spindle speed firm without motor bogging or gear slippage under extreme load. The induction-hardened V-ways maintain carriage alignment within 0.0005 inches across the entire 130-inch bed length. Sound profile meters measure 84 dBA during active cutting. Headstock oil bath temperatures increase 38°F after three continuous hours of heavy turning.

Field Operation Usability Maintenance Directives

Machinists mount heavy workpieces using overhead cranes and select spindle speeds via the headstock levers. The quick-change gearbox allows instant thread pitch selection. Do not operate this industrial lathe without proper eye protection, exceed the 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.
