JET GH-2180ZX Large Spindle Bore Gear Head Lathe with Acu-Rite 203 and Taper Attachment Kit

Description

Wrestle big shaft forgings onto centers without watching your carriage twist under heavy tool loads. The JET GH-2180ZX Large Spindle Lathe delivers rigid turning power across a 21 in swing and 80 in centers. A 10 HP motor drives cuts through a 3-1/8 in bore. The taper kit turns tapers without offset setups, though high mass demands crane hoists.

Monolithic Meehanite gray iron gives this bed casting the mass needed to kill deep roughing chatter. Induction-hardened bedways reach 60 HRC, stopping abrasive swarf from gouging ways. The 10 HP motor runs on 230V or 460V 3-phase, drawing 27 FLA under 230V load. Total machine weight reaches 7,300 lbs on shop floor dimensions of 138 in long by 42 in wide.

Key Features of JET JT1-3312

Plant rebuilders choose this large-bore lathe to turn hydraulic cylinder rods, true drive shafts, and cut marine prop threads. Check regional machinery dealers to buy JET JT1-3312 units for severe industrial repair service.

• Acu-Rite 203 digital readout tracks axis positions down to 0.0001 in resolution on a glare-free screen.
• Cut steep angles up to 10 degrees per side without tailstock offset adjustments using the taper attachment.
• Pass thick rod stock and pipe straight through the headstock with the 3-1/8 in spindle bore.
• Camlock D1-8 spindle nose locks chucks solid to suppress cut vibration on out-of-round billets.
• Twelve geared headstock speeds span 25 to 1,600 RPM for turning stainless and tough alloy steels.
• Rapid traverse joystick moves the heavy apron down the 80 in bed to eliminate physical strain.
• Drop the removable bed gap to turn large pump impellers up to 29 in diameter.

Bench Load Deflection Spindle Stability

Indicator tests confirm spindle nose runout under 0.0003 in TIR at the chuck register face. Rip a 0.200 in deep chip from 4340 alloy steel, and carriage feed thrust hits 1,600 lbs with zero bed twist. Spindle speed drops just 10 RPM at 85 RPM under peak chip load. The pressurized headstock oil pump maintains 22 PSI, keeping bearings under 135°F during all-day roughing runs.

Traverse Control Operator Maintenance Steps

The 4-way traverse lever engages feeds with distinct mechanical detents, stopping unwanted carriage travel on fine cuts. Heavy iron mass absorbs cutting shocks before they reach your hands. Do not buy this machine for delicate small brass work or shops lacking 3-phase electrical drops.

• Inspect the headstock oil sight glass every morning and top off with ISO 68 machine oil.
• Grease apron drive gears and rapid traverse bearings every 40 hours using NLGI 2 grease.
• Brush iron swarf away from bedway wipers every day to stop grit from sliding under the saddle.
