Description
Automate table feed passes and eliminate operator handwheel fatigue across standard manual milling machines. The JET X-Axis Table Powerfeed for milling machines delivers motorized longitudinal travel with variable feed rates from 0 to 38 IPM. This electric accessory bolts to table ends. It requires 115V single-phase electrical power to drive its internal reduction drive motor.
Solid cast aluminum forms the drive gear housing, protecting the electric motor and bevel reduction gears against accidental shop impacts. A high-torque DC motor pairs with precision ground bevel gears, transferring steady rotational force into the table lead screw. The front control panel features a directional control lever, speed adjustment knob, and rapid traverse push button that moves the table at 200 IPM. Mechanical limit stops mount to the table to disengage feed automatically.
Key Features of JET JT9-350194
Fleet repair machinists install this power feed unit onto manual mills to produce uniform face-milled finishes. The rapid traverse button accelerates workpiece positioning between cuts.
- Variable feed rate dial adjusts longitudinal table transit speed from 0 to 38 inches per minute
- Rapid traverse push button engages 200 IPM high-speed table travel for fast setups
- 115V single-phase electrical operation connects to standard shop wall electrical outlets
- Precision ground bevel gear drive transfers smooth torque into table lead screws without chatter
- Directional control lever selects forward, neutral, and reverse table movements with positive stops
- Adjustable mechanical limit switch stops shut off motor feed at pre-set travel points
- Universal mounting bracket fits standard Bridgeport and JET manual vertical turret mills
Power Feed Dynamometer Bench Telemetry
Dynamometer pull tests verify 140 inch-pounds of continuous feed torque at 15 IPM under heavy milling loads. Rapid traverse speed clocks 202 IPM with zero motor stall under 450 lbs of table load. Motor current draw stabilizes at 2.4 amps on 115V power during continuous cutting passes. Limit switch shut-off repeatability measures within 0.002 inches on table stops. Acoustic sound levels remain under 62 dBA during operation.
Power Feed Installation Safety Directives
Bolt the mounting flange square against the machine table end and verify bevel gear backlash measures between 0.004 and 0.008 inches. Set the mechanical table stops securely before engaging feed passes to prevent tool crashes into vises. Never reach over the moving lead screw while rapid traverse mode operates.
- Bevel drive gears demand multi-purpose lithium grease application every three months
- Electric motor carbon brushes require inspection and replacement every 1000 run hours
- Limit switch electrical cord requires visual checks to identify cracked insulation or cuts
