Jet Equipment JT9-690646 Vertical Mill 10x50 Table Dro

Product Description

The JET EQUIPMENT JT9-690646 is a 230-volt electronic variable speed vertical knee milling machine built on Meehanite castings for rigidity and long-term tolerance retention. The table measures 10 inches by 50 inches, the spindle accepts R-8 tooling, and spindle speed is continuously variable from 60 to 4500 RPM. A Newall DP700 digital readout covers three axes including the quill, and powered X and Y-axis powerfeeds are included. The machine is intended for installation and operation by trained machinists and millwrights in production and job-shop environments where consistent metal removal accuracy is required.

The JT9-690646 is suited for light to heavy milling operations in machine shops, maintenance facilities, and trade training environments. The 10 x 50 inch table accommodates a wide range of workholding fixtures. The swing-away control box positions the E-stop and all operator controls within reach during cutting. Two 115-volt outlets in the relocated rear electrical box support powered accessories such as coolant pumps or lighting. The machine ships as a complete package including the Newall DP700 DRO, X and Y powerfeed units, LED work lamp, chip pan, swing-away safety shield, way covers, drawbar, and a tool box with tools.

Key Features

• Meehanite casting construction with enhanced ribbing for rigidity and tolerance retention under heavy cuts
• Electronic variable speed spindle from 60 to 4500 RPM with no belt changes required
• Newall DP700 3-axis digital readout with quill axis included
• X and Y-axis powerfeeds for consistent feed rates and reduced operator fatigue
• Table and ways hardened to 54 HRC and precision ground; X and Y axes coated with Turcite-B for smooth, low-vibration movement
• Automatic oiler dispenses 3 to 6 cc per cycle at adjustable intervals to lubricate ways and critical surfaces
• Heavy-duty spindle brake stops spindle rotation and interrupts power to prevent accidental restarts
• Redesigned column and base levels without lifting the machine off the floor

Compatibility

Designed as a self-contained vertical knee mill. The R-8 spindle taper is compatible with the industry-standard R-8 collets, end mill holders, and shell mill adapters common to this machine class. No additional control board or drive compatibility applies.

Installation Notes

Installation should be performed by a qualified millwright or machinery rigger. The machine weighs 2580 pounds and requires appropriate lifting equipment and anchoring per local machinery installation codes before operation. Electrical connection at 230 volts must be performed by a licensed electrician in accordance with applicable NEC requirements. Level the machine using the integrated base leveling system before powering up, and verify all axis locks and E-stop function before initial operation.
