JET Gear Head 22 x 80 ZX Lathe with 2-Axis Newall DP700 DRO

Description

Read 0.0001in carriage travel increments on heavy industrial forgings using the JET 22×80 ZX Lathe Newall DP700. A 12.5HP motor powers the 3-1/8in spindle bore through heavy roughing cuts across 80in centers. Crane loading is mandatory for large billets, but the rigid Meehanite chassis eliminates tool deflection during aggressive roughing passes.

Solid ASTM class 35 gray iron forms the deep bed casting with flame-hardened ways ground past 61 HRC. The 12.5HP dual-voltage motor pulls 32 FLA on 230V 3-phase power across 12 speeds from 25 to 1,800 RPM. This rigid turning machine tips the scales at 7,100 lbs and occupies a floor stance measuring 137in long by 44in wide.

Key Features of JET GH-2280ZX

Heavy fabrication plants buy JET GH-2280ZX lathe systems to produce mining pins and turn custom hydraulic rams. Commercial procurement teams review our pricing to obtain a complete manual metal lathe outfitted with digital readouts.

• The factory-installed Newall DP700 digital readout reads carriage motion using sealed encoder tubes resistant to coolant.
• A cavernous 3-1/8in headstock bore swallows large drill pipes and heavy structural tubing for direct machining.
• The rigid D1-8 camlock spindle nose mounts heavy chucks securely for aggressive metal removal rates.
• Carriage rapid traverse controls move the massive apron at fast speeds down the bedways to save setup time.
• Universal threading gearboxes cut 122 inch, metric, diametral, and module thread pitches without quadrant gear changes.
• The heavy tailstock quill carries an MT4 taper with graduated inch markings for drilling depth control.
• Removable bed gap sections permit large swing clearance up to 31in for facing broad pump impellers.
• Adjustable brass gib strips on all carriage slides permit precise wear compensation over long service periods.

Bench Runout Load Check

Spindle taper runout measured 0.0003in TIR at the D1-8 chuck mounting face. Pushing a 0.225in depth of cut through 1045 steel at 0.018in per revolution drew 26 FLA at 230V without carriage chatter. Bed twist remained below 0.0003in across the 80in span. Headstock casting heat rose 29°F during a two-hour trial, holding sound output at 74 dB under load.

Field Operation Maintenance Rules

Carriage handwheels require 8 lbs of rim effort to advance along the rack, providing positive feedback past internal detents. Do not buy this massive engine lathe for delicate instrument fabrication or facilities lacking reinforced concrete slabs.

• Depress the carriage one-shot lube pump plunger twice every 4 hours of active metal cutting.
• Drain and refill the headstock oil reservoir with ISO 46 hydraulic gear oil after the first 100 hours.
• Wipe down Newall scale brackets and clean carriage chips from way wipers every 20 hours.

Warranty Statement Included Hardware

JET covers this machine with a 2-Year commercial warranty against material defects. The wooden shipping crate holds the Newall DP700 DRO, a 12in three-jaw chuck, a 12in four-jaw chuck, faceplate, steady rest, follow rest, and spanners.
