Jet Equipment JT9-690644 Variable Speed Milling Machine

Product Description

The JET EQUIPMENT JT9-690644 is a 10-inch by 50-inch electronic variable speed vertical milling machine built for demanding production and job-shop environments. Constructed using the Meehanite casting process with enhanced internal ribbing, the machine delivers rigidity and tolerance retention across heavy cutting cycles. Spindle speed runs continuously variable from 60 to 4500 RPM, eliminating belt changes during setup. The package includes a Newall DP700 digital readout configured for 3-axis operation with a quill-mode display and an X-axis powerfeed. Licensed HVAC and mechanical trades as well as production machinists will find this machine suited to precision milling, drilling, and boring work.

The JT9-690644 is designed for installation in machine shops, maintenance departments, and light industrial facilities requiring a full-size knee mill with integrated DRO capability. The Newall DP700 DRO supports quill operation directly, making it well suited to tool-and-die work and general production milling. The X-axis powerfeed reduces operator fatigue during long table traversals. The machine ships as a complete unit with chip pan, LED work lamp, swing-away safety shield, drawbar, way covers, and a toolbox with tools included.

Key Features

• Meehanite cast construction with enhanced ribbing for rigidity and tolerance retention under heavy cuts
• Electronic variable speed spindle: 60 to 4500 RPM with no belt changes required
• Newall DP700 3-axis DRO with quill-mode display included
• X-axis powerfeed included for reduced operator fatigue on long passes
• Table and ways hardened to 54 HRC and precision ground; X and Y axes coated with Turcite-B for smooth, vibration-dampened movement
• Swing-away control box with E-stop and heavy-duty spindle brake prevents accidental start-up
• Automatic oiler delivers 3 to 6 cc per cycle at adjustable intervals; internally cooled spindle head extends bearing, belt, and motor service life
• Electrical box relocated to rear of machine and includes two 115-volt accessory outlets; CSA/cUS certified

Compatibility

The JT9-690644 is the JTM-1050EVS2/230 mill configured with the Newall DP700 3-axis DRO (quill mode) and X-axis powerfeed. Accessories and tooling using an R-8 spindle taper are compatible with this machine.

Installation Notes

Installation should be performed by qualified millwrights or industrial equipment technicians. The redesigned base allows the machine to be leveled without lifting it off the floor, but adequate fork or crane capacity rated for the machine weight is required for placement. Verify that the facility electrical supply matches the 230-volt single-phase requirement before connecting power. All guarding, including the swing-away safety shield, must be in place and the E-stop verified functional before initial operation.
