Jet 690038 Vertical Milling Machine 1-1/2 Hp R-8 Taper

Product Description

The JET 690038 is a vertical knee milling machine built for precision metalworking in machine shops and industrial maintenance environments. It features an 8 inches x 36 inches worktable and an R-8 taper spindle, the standard taper for this class of Bridgeport-style mills. Power comes from a 1-1/2 HP motor running on 3-phase power at 230/460 volts. The R-8 spindle accepts a wide range of collets, end mill holders, and boring heads, making this machine adaptable to a broad set of milling, drilling, and boring operations. At 1,610 pounds, this is a full-size floor-standing machine intended for permanent or semi-permanent shop installation.

This vertical knee mill is suited for job shops, maintenance departments, vocational training facilities, and light production environments. It handles face milling, end milling, slot cutting, drilling, and boring on ferrous and non-ferrous metals. The 3-phase electrical requirement means it is intended for commercial or industrial facilities with appropriate service. A licensed electrician or qualified millwright typically handles final installation and electrical connection.

Installation Notes

Installation requires a licensed electrician to connect the 3-phase 230/460-volt supply in compliance with NEC requirements. The machine must be leveled on a concrete floor of adequate thickness using leveling mounts or anchor bolts per the manufacturer instructions. Always disconnect and lock out the main power supply before changing tooling, adjusting gibs, or performing any maintenance. Rigging to final position should be performed by qualified personnel using appropriate lifting equipment rated for the 1,610-pound machine weight.
