JET BDB-1340A Belt 13 In. Swing 40 In. Centers 2 HP 1Ph 230 V Only

Description

Smooth belt pulleys transfer 2HP of rotary torque straight to the spindle without gear train chatter. The JET BDB-1340A Belt Drive Lathe provides toolmakers with quiet turning across a 13in swing and 40in centers. Single-phase 230V wiring connects to standard shop drops. Belt drive cushions tool shock, though speed adjustments require moving belts manually across pulley steps.

Solid Meehanite gray iron casting forms this bed structure, ribbed to stop harmonic resonance on fine passes. Induction-hardened bedways test at 60 HRC to prevent chip scratching and carriage wear. The 2HP single-phase motor runs on 230V power, drawing 11 FLA. Multi-step pulleys run inside an enclosed headstock cabinet. The tool weighs 1,150 lbs on floor dimensions of 68in long by 30in wide.

• Single-phase 230V motor plugs straight into standard workshop electrical drops without rotary converters.
• D1-4 camlock spindle nose mounts 3-jaw and 4-jaw chucks with solid radial lockup and fast chuck swaps.
• Enclosed quick-change gearbox provides feeds for cutting 40 imperial and 23 metric thread pitches.
• Removable bed gap expands work diameter clearance up to 18-3/4in right forward of the chuck face.
• Separate lead screw and feed rod stop premature leadscrew thread wear during standard turning cuts.
• Front-mounted emergency stop button cuts electrical control power to halt spindle momentum fast.

Belt Drive Spindle Runout Data

Dial test indicators show spindle nose runout under 0.0003in TIR measured at the chuck register face. Take a 0.080in deep cut in 6061 aluminum, and you get an ultra-smooth finish with zero belt slippage. Motor startup current draws 26A for 0.4 seconds before dropping to 3.8A idle draw. Carriage feed thrust holds steady at 600 lbs with zero bed twist. Spindle bearings run cool, rising just 22°F above ambient.

Apron Handling Routine Maintenance Rules

Carriage handwheels turn with 3 lbs of rim force, giving you smooth tactile feedback on fine facing cuts. The belt tension lever releases belt grip fast for quick step changes. Do not buy this belt-driven lathe for heavy industrial oilfield pipe roughing or continuous 24-hour factory shifts.

• Spread ISO 68 way oil over the bedways, cross slide, and tailstock quill every morning before work.
• Inspect headstock drive belts for surface cracking and proper tension every 60 operating hours.
• Adjust cross slide brass gib screws every 3 months to keep handwheel backlash under 0.003in.
