JET GH-26120ZH with ACU-RITE 303 DRO Metalworking Lathe

Description

Meehanite gray iron aged outdoors through hot summers and freezing winters forms this massive 10-foot lathe bed. The JET GH-26120ZH Lathe with DRO gives industrial rebuilders rigid turning across 120 in between centers. A 15 HP motor drives cuts through a 4-1/8 in bore. The ACU-RITE DRO speeds setups, though long shafts demand steady rest support.

Class 35 Meehanite iron forms this monolithic 120 in bed casting, cross-ribbed to stop torsional twist under heavy billets. High-frequency induction hardening brings the ways to 60 HRC. The 15 HP motor runs on 230V or 460V 3-phase, drawing 42 FLA at 230V. Total lathe weight hits 9,800 lbs on shop floor dimensions of 188 in long by 50 in wide.

Key Features of JET JT9-321896

Marine repair yards and turbine rebuilders turn to this long-bed lathe to machine propeller shafts, bore hydraulic cylinders, and turn mill rolls. Check distributor freight terms to buy JET JT9-321896 machines for heavy turning departments.

• Extended 120 in distance between centers holds long drive tubes, marine shafts, and crane cylinders.
• ACU-RITE 303 digital readout displays position feedback down to 0.0001 in resolution on an LED screen.
• Massive 4-1/8 in spindle bore passes heavy drill strings straight through the headstock.
• D1-11 camlock spindle nose mounts heavy chucks with rigid contact to suppress chatter under severe cuts.
• Twelve geared headstock speeds from 12 to 1,000 RPM produce massive turning torque for tough alloy forgings.
• Rapid traverse 4-way joystick drives the heavy carriage along the 120 in bed to reduce worker fatigue.
• Removable bed gap swings large pump housings up to 34 in diameter right before the chuck face.

Long Bed Deflection Spindle Bench Data

Dial indicator tests confirm spindle nose runout under 0.0003 in TIR measured at the D1-11 seat. Turning a 2,500 lbs steel shaft between centers produces less than 0.0008 in bed deflection down the full 120 in span. Take a 0.250 in deep cut in 4140 steel, and carriage feed thrust reaches 2,200 lbs without chatter. Headstock oil pressure stays at 24 PSI, keeping bearings under 140°F.

Traverse Control Heavy Rigging Servicing

The 4-way rapid traverse joystick glides the heavy carriage down 10 feet of bed at 12 feet per minute, stopping dead upon release. High machine mass absorbs cutting vibration before shock numbs the apron handwheel. Do not buy this 9,800 lbs lathe for small repair shops or unreinforced thin concrete floors.

• Check the headstock oil sight glass every morning and top off with ISO 68 machine oil.
• Grease carriage apron drive gears and rapid traverse bearings every 40 hours with NLGI 2 grease.
• Clean steel swarf chips from the bedway wipers every day to stop dirt intrusion under the saddle.
