JET JTM-1254VS 200S 3X-Q X PFD APDB Vertical Milling Machine

Description

Clamp heavy tooling fixtures to the JET JTM-1254VS Powerfeed Milling Machine to square broad plate stock. This unit pairs a 3HP electronic variable speed drive with a 12in by 54in table, table power feed, and air drawbar. The pneumatic drawbar speeds cutter changes, but requires a dry shop air connection supplying 90 PSI to prevent air motor stalls.

Stress-relieved Meehanite gray iron castings form the structural frame, deadening harmonic vibration during heavy face milling passes. The 3HP inverter motor runs on 230V or 460V three-phase power at 9.5 FLA, driving the R8 spindle between 60 RPM and 4,300 RPM. This vertical mill requires an operating floor stance of 98in by 85in and anchors with 3,120 lbs of mass.

Key Features of JET JTM-1254VS

Machine shops buy JET JTM-1254VS equipment to machine mold plates and machine bases without operator fatigue. Commercial machinery pricing reflects the integrated power feeds and pneumatic drawbar designed to shorten setup cycles across production shifts.

• An air power drawbar secures and ejects R8 toolholders in three seconds via pneumatic valve actuation.
• The ACU-RITE 200S readout tracks table positions along with quill travel through precision glass scales.
• A factory table power feed drives the X-axis to ensure uniform cutter chip load across long surfaces.
• A ground 12in by 54in work table supports fixture and stock weight up to 925 lbs without table sag.
• Continuous variable speed electronics let operators tune cutter RPM via dial without stopping spindle motion.
• Wide induction-hardened box ways on the knee eliminate carriage rock under heavy offset loads.
• Turcite-B way coatings prevent stick-slip friction during slow manual or motorized boring passes.

Spindle Deflection Bench Runout Tests

Bench indicator testing confirms spindle taper runout remains under 0.0002in TIR. Facing 1018 cold-rolled steel with a 3in carbide cutter at 0.125in depth of cut causes 0.0005in carriage deflection. Motor current holds steady at 8.4A under load. Operating sound registers 72 dB, while the spindle bearing head housing stabilizes at 120°F after three continuous hours of test milling.

Ergonomic Control Operational Misapplication Warnings

Manual table handwheels engage lead screws with 6 lbs rim resistance, providing direct tactile feedback through fine finishing cuts. The pneumatic drawbar switch actuates with 2 lbs thumb pressure. Do not buy this 3,120 lbs production mill for light hobby garages without three-phase electrical service.

• Actuate the central lubrication pump handle once every 4 hours using clean ISO 68 way oil.
• Drain moisture from the air regulator filter bowl every 8 hours to protect the drawbar cylinder.
• Check table power feed gear alignment and grease drive teeth with NLGI 2 grease every 100 hours.
