Jet Equipment JT9-691190 Vertical Mill Newall C80 3-axis Dro

Product Description

The JET EQUIPMENT JT9-691190 is a vertical knee milling machine equipped with a Newall C80 3-axis digital readout (DRO) and quill feed system. It is built around Meehanite castings for rigid, vibration-damping construction and features Class 7 high-precision spindle bearings for accurate, repeatable cuts. The spindle head is internally cooled to prevent heat buildup and seizing during extended operations. A three-stage power downfeed with automatic stop gives operators precise control over quill travel. This machine is installed and operated by skilled machinists and tool-and-die professionals in job shops and production environments.

The JT9-691190 is suited for vertical milling operations in industrial, commercial, and vocational settings. It is designed for use with the JTM-1 and JTM-2 series configurations. The integrated Newall C80 DRO provides 3-axis position readout, reducing setup time and improving part accuracy. An internal coolant tank is built into the base for use with an optional coolant system. The machine ships with a tolerance test sheet, one-shot lubrication system, way covers, drawbar, and a tool box with tools included.

Installation Notes

Installation and setup should be performed by a qualified machinist or millwright. The machine must be properly leveled and anchored to a suitable floor surface before operation. All electrical connections must comply with applicable local codes and the NEC. Disconnect and lock out all power before performing any service, tooling changes, or spindle work. A coolant pump is not included and must be sourced separately for wet-cutting operations.
