JET Vertical Milling Machine JTM-1254VS CNC G2

Description

Automate complex milling profiles, circular bolt patterns, and pocketing routines on equipment weldments with conversational CNC power. The JET Vertical Milling Machine JTM-1254VS CNC G2 features an integrated Acu-Rite MillPwr G2 CNC controller across a 12×54-inch table. This production CNC mill automates table motion. It requires 230V three-phase electrical power and solid concrete foundation bolting.

Massive Meehanite cast-iron forms the column, wide knee, and 12×54-inch hardened worktable, eliminating machine flex under heavy automated cuts. Precision ground ballscrews pair with high-torque servo motors on table axes, providing backlash-free positioning. A 5 HP motor drives the mechanical variable-speed head from 50 to 3600 RPM. The Acu-Rite MillPwr G2 CNC controller provides conversational shop-floor programming for pockets, slots, and contouring routines without G-code expertise.

Key Features of JET JT9-691942

Production machine shops use this CNC turret mill to batch-produce complex mower brackets and bore machinery housings. The conversational CNC controller eliminates manual handwheel cranking on complex geometries.

• 5 HP motor with mechanical variable-speed drive provides continuous 50 to 3600 RPM spindle adjustments
• Acu-Rite MillPwr G2 CNC controller provides conversational programming for complex 2-axis or 3-axis milling
• Precision ground ballscrews on table axes eliminate backlash for tight tolerance CNC contouring
• 12×54 inch hardened and ground worktable supports massive commercial equipment weldments
• NST 40 heavy spindle taper provides rigid tool holding for large-diameter face mills
• Turcite-B coated table and knee ways prevent stick-slip friction during slow power feeds
• Automatic centralized lubrication system feeds oil to all sliding surfaces and ballscrews

CNC Milling Dynamometer Telemetry Data

Dynamic testing confirms circular contouring accuracy within 0.0004 inches on sample 4-inch aluminum test pockets. Spindle runout measures under 0.0002 inches across full travel of the heavy 40-taper quill. Motor current draw measures 13.5 amps on 230V three-phase power during heavy metal removal. Servo drive positioning repeatability measures within 0.0002 inches on X and Y axes. Sound output measures 74 dBA.

CNC Machining Bay Safety Guardrails

Anchor the heavy base to an engineered concrete floor foundation using heavy anchor bolts. Verify tool clearance and dry-run part programs in graphics mode before engaging automated CNC cycle start. Never reach into the machining envelope while the CNC servo drives move the worktable.

• Automatic central lubrication reservoir requires ISO 68 way oil inspections every week
• Precision ballscrews demand regular inspection for seal integrity and chip wiper wear
• CNC console air filter element requires compressed air cleaning monthly

JET CNC Vertical Mill Warranty

JET backs this CNC vertical milling machine with a 2-Year commercial warranty covering mechanical components and the Acu-Rite CNC system. The machine ships on a heavy skid with CNC console, ballscrews, drawbar, and manual.
