Description
Mill precision mounting slots, drill bolt hole patterns, and face commercial cutter housings with inverter speed control and automated table transit. The JET Variable Speed Geared Head mill drill package features a Newall DP700 2-axis digital readout and X-axis power feed. This square column machine combines electronic speed control with automated transit. It requires 230V single-phase electrical power to operate.
Solid cast-iron forms the square column upright, damping out cutting chatter during aggressive slotting passes. A 1.5 HP motor pairs with an electronic inverter drive, providing variable spindle speeds from 65 to 2000 RPM. Motorized X-axis table power feed provides continuous table movement with rapid traverse override. The Newall DP700 2-axis DRO uses spherical scale sensors to track table position within 0.0002 inches.
Key Features of JET JT9-351157
Fleet repair machinists use this equipped mill drill to machine custom mower spindles and slot chassis brackets. The combination of power feed and digital readout eliminates manual crank errors.
- 1.5 HP motor with electronic inverter delivers variable spindle speeds across 65 to 2000 RPM
- Newall DP700 2-axis digital readout displays precise X and Y axis table coordinates
- Motorized X-axis power feed delivers automated table transit with rapid traverse control
- Square column design prevents head rotation during elevation adjustments to hold location
- Three-speed automated power downfeed advances the quill under controlled drilling thrust
- R8 spindle taper accepts standard industrial collets, end mill holders, and boring heads
- Precision ground cast-iron worktable features three 5/8-inch T-slots for rigid vise mounting
Square Column Machining Dyno Telemetry
Spindle load tests verify continuous slotting of 1018 steel using a 3/4-inch end mill at 420 RPM with zero gear chatter. X-axis power feed maintains table feed speed within 2 percent across varying cutter loads. Spindle radial runout measures under 0.0004 inches at the spindle nose. Motor current draw measures 8.1 amps on 230V single-phase power during heavy cutting. Acoustic sound output measures 75 dBA.
Production Milling Setup Safety Guardrails
Anchor the machine base securely to a reinforced concrete floor slab before running automated table feeds. Verify table travel stops before engaging the X-axis power feed to prevent vise crashes. Never reach across the rotating cutter to clear metal chips; use a specialized chip scraper.
- Geared spindle head requires ISO 68 industrial gear oil changes every 1000 hours
- Quill feed rack and square column ways demand daily lubrication with ISO 68 way oil
- Newall digital readout scale reader heads require periodic clean wipes to remove coolant mist
