JET 14 x 40 Geared Head Bench Top Lathe

Description

Meet ANSI toolroom safety codes with fully enclosed lead screws and protective chuck interlock switches. The JET 14×40 Geared Bench Lathe gives machinists rigid turning power across a 14 in swing and 40 in centers. A 2 HP motor drives 8 geared speeds. The bench stance saves floor space, but steel stands require concrete floor anchor bolts.

Meehanite gray cast iron forms this ribbed monolithic bed, stress-relieved to maintain alignment under load. Induction-hardened bedways test at 60 HRC to prevent chip scratching and carriage wear. The 2 HP motor operates on 230V single-phase power, drawing 11 FLA. Total unboxed weight reaches 1,450 lbs on bench dimensions of 68 in long by 30 in wide.

Key Features of JET JT9-331440

Maintenance mechanics and machinery rebuilders pick this geared lathe to turn motor shafts, cut replacement lead screws, and face flanges. Inquire about equipment dealer inventory to buy JET JT9-331440 packages for commercial repair shops.

• Eight geared headstock speeds from 70 to 1,500 RPM provide heavy torque for roughing and high speed for polishing.
• D1-4 camlock spindle nose mounts 3-jaw, 4-jaw, and collet chucks with solid radial lockup.
• Quick-change gearbox provides feeds for cutting 40 imperial and 23 metric thread pitches without gear swaps.
• Removable bed gap expands work diameter clearance up to 20 in right forward of the chuck face.
• Separate lead screw and feed rod stop premature leadscrew thread wear during standard turning cuts.
• Full-length splash guard keeps high-pressure coolant from spraying onto back shop walls.
• Front-mounted emergency stop button cuts electrical control power to halt spindle momentum fast.

Spindle Nose Runout Load Metrics

Dial test indicators confirm spindle nose runout under 0.0003 in TIR measured at the chuck register face. Take a 0.100 in deep cut in 1045 cold-rolled steel, and carriage feed thrust hits 750 lbs with zero bed twist. Spindle speed drops by 14 RPM under heavy parting tool loads at 320 RPM. Headstock casting heat peaks at 130°F after 3 hours of continuous cutting.

Apron Lever Action Preventative Shop Care

Carriage feed levers click into travel positions with positive mechanical detents, preventing accidental feeds into rotating chucks. Handwheels turn without drag, giving you fine control on critical facing passes. Do not buy this bench lathe for heavy oilfield casing pipes or production bar feeding runs.

• Spread ISO 68 way oil across the bedways and cross slide surfaces every morning before starting work.
• Check headstock gear oil level through the sight glass window every 30 days.
• Adjust cross slide brass gib screws every 3 months to keep handwheel backlash under 0.003 in.
