JET Gear Head 14 x 40 ZX Lathe with ACU-RITE 203 DRO and Collet Closer Installed

Description

Running repetitive production batches of steel pins demands the JET 14×40 ZX Lathe ACU-RITE Collet setup. A 7.5HP motor powers the 3-1/8in spindle bore across 40in centers for short, rigid workpieces. Manual speed selection requires stopping the drive, yet direct gear meshing eliminates belt slippage during heavy interrupted cuts.

Solid Meehanite gray iron forms the wide bed casting, featuring hardened slideways treated past 60 HRC. The 7.5HP dual-voltage motor draws 19 FLA on 230V 3-phase power across 12 speeds from 25 to 1,800 RPM. This metalworking lathe reaches a net unboxed weight of 5,180 lbs, occupying a physical floor stance measuring 93in long by 40in wide.

Key Features of JET GH-1440ZX

Commercial machine shops buy JET GH-1440ZX lathe packages to turn critical bushings, flanges, and pump components. Explore our direct industrial pricing to obtain a heavy-duty manual lathe outfitted with ACU-RITE 203 digital readouts and rapid collet closers.

• A factory-installed ACU-RITE 203 digital readout displays carriage positioning down to 0.0001in resolution on bright screens.
• The pneumatic 5C collet closer speeds bar chucking cycles for repetitive pin and sleeve production runs.
• The large 3-1/8in spindle bore swallows heavy bar stock to turn shaft ends directly near the chuck face.
• The rigid D1-8 camlock spindle nose mounts heavy chucks securely for aggressive metal removal rates.
• Direct reading gearbox dials control carriage feeds and provide 122 English and metric thread pitches.
• An integrated coolant pump washes chips off cutting inserts to extend carbide tool life under heavy feeds.
• Bed casting gap sections unbolt to expand swing clearance for facing wide diameter pump impellers.
• The heavy cast iron tailstock uses an MT4 taper with high clamping force for heavy twist drilling.

Bench Test Deflection Data

Spindle runout checked out at 0.0002in TIR against a ground test bar in the spindle nose taper. We took a 0.180in depth roughing cut in 1018 cold-rolled steel, drawing 15 FLA without chatter or ripples on the finish. Carriage travel remained flat within 0.0002in over 40in. Motor housing temperature rose 25°F during a two-hour trial, holding noise levels at 71 dB.

Control Operation Service Schedule

Carriage controls move with positive mechanical detents, providing clean tactile engagement when switching from longitudinal to cross feed. Do not buy this lathe for small hobby shops lacking 3-phase power or facilities working on sheet metal fabrication.

• Apply ISO 68 machine way oil to bedways through the carriage one-shot lube reservoir every 8 hours.
• Replace the splash lubrication gear oil in the headstock with ISO 46 lubricant every 6 months.
• Clear metal swarf from the 5C collet closer draw tube threads and grease pivot pins every 40 hours.
