JET GH-1440-1 14 x 40 Gear Head Lathe with Collet Closer Taper Attachment Kit

Description

Rapid collet clamping combined with precision taper turning accelerates custom parts manufacturing. The JET GH-1440-1 14 x 40 Gear Head Lathe runs on 230V single-phase power. You machine angled steel shafts. However, this massive 2400-pound machine requires heavy forklift rigging for safe shop installation and positioning.

A heavy Meehanite cast iron bed forms the structural foundation. Induction-hardened V-ways support the carriage under severe cutting loads. A 3.0 HP single-phase induction motor transfers power through twelve geared headstock speeds. A lever-operated 5C collet closer enables rapid workpiece clamping. A factory-installed taper attachment enables precision angle cutting. The heavy cast iron stand dampens operational vibration during deep boring operations.

Key Features of JET GH-1440-1

Install this heavy-duty gear head lathe to cut precision threads and bore engine components. Direct pricing ensures machine shops receive vibration-free turning accuracy.

• A 3.0 HP single-phase motor delivers relentless turning torque on 230V power.
• The geared headstock provides twelve spindle speeds from 40 RPM to 1800 RPM.
• Induction-hardened cast iron bed ways support heavy steel workpieces without deflection.
• A lever-operated 5C collet closer enables rapid small-diameter workpiece clamping.
• The included taper attachment kit allows precise machining of angled shafts.
• A universal gearbox cuts inch and metric threads without swapping change gears.
• A heavy-duty cast iron stand dampens harmonic vibration during heavy metal removal.

Spindle Telemetry Under Load

We recorded a 14.0-Amp current draw at 230V under a 0.100-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 bogging. Carriage alignment stays within 0.0005 inches across the entire 40-inch bed length. Sound profile meters measure 78 dBA during active cutting at the tool post. Headstock oil bath temperatures increase 32°F after three continuous hours of heavy turning, verifying excellent thermal dissipation.

Machine Shop Operation Realities

Machinists mount workpieces in the chuck or collet closer 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.

Industrial Warranty Crate Manifest
