JET GH-1440ZX Metalworking Lathe

Description

Achieve true roundness tolerances on turned parts without paying for CNC infrastructure costs. The JET GH-1440ZX Metalworking Lathe provides traditional machinists with massive casting stability across a 14 in swing. A 3 HP motor turns 12 gear speeds to tackle hard steels. The removable gap bed swings 20 in for large faceplate work, though lack of digital readouts requires manual micrometer verification.

Solid Meehanite casting forms the foundation, damping vibrations through thick cross-ribbed internal walls. Ground bedways feature induction hardening to 62 HRC for wear resistance against abrasive materials. The 3 HP motor runs on 230V 3-phase power, pulling 9 FLA at nominal speed. The machine weighs 2,460 lbs, presenting a physical shop floor footprint of 79 in long by 39 in wide.

Key Features of JET 321301

Vocational shops and farm repair specialists depend on this lathe to true tractor axles, rework drive splines, and cut threads. Check distributor availability to buy JET 321301 lathes to equip plant service workshops.

• Massive cast iron base dampens heavy cutting forces when roughing off-center casting forgings.
• Twelve geared headstock speeds span 40 to 1,800 RPM to accommodate carbide and high-speed steel bits.
• D1-4 camlock spindle provides rigid mount connections for three-jaw, four-jaw, and collet chucks.
• Universal gearbox cuts 40 inch thread pitches and 23 metric pitches without swapping change gears.
• Removable gap bed section expands work diameter clearance up to 20 in directly forward of chucks.
• Foot brake pedal stops spindle rotation swiftly for part measurements without waiting on coasting mass.
• Heavy-duty compound rest rotates 360 degrees for chamfering and turning steep bevel profiles.

Vibration Resistance Bed Deflection Data

Dial indicator measurements demonstrate spindle nose runout under 0.0003 in TIR. Taking a 0.150 in deep cut in 1018 cold-rolled steel at 300 FPM produces less than 0.0004 in bedway deflection. Spindle speed drops by 14 RPM under severe roughing torque loads. Headstock gearbox noise measures 74 dB at operator ear level during 1,200 RPM operation. Tailstock alignment holds parallel to the spindle within 0.0004 in.

Manual Dial Feedback Maintenance Directives

Satin-chrome carriage and cross slide collars feature crisp black engraving for reading thousandths through oily safety glasses. Feed selection knobs lock into place with heavy detents that resist accidental bumping. Do not buy this bare manual lathe for fast production threading without digital DRO readouts.

• Pump the one-shot bedway lube plunger before daily machining to prevent way scoring.
• Drain the headstock break-in oil after 90 days and refill with fresh ISO 68 machine fluid.
• Wipe down precision ground ways with clean shop rags and coat with light oil after shifts.

JET Red Assurance Warranty Manifest
