Jet 690093 Vertical Knee Mill 3-axis C80

Product Description

The JET 690093 is a JTM-4VS vertical knee mill equipped with a C80 3-axis digital readout package covering the knee, X, Y, and Z axes. This machine is built for precision metal removal in job shop, toolroom, and light manufacturing environments. The TPFA (Tilting Power Feed Assembly) configuration adds powered table feed capability, reducing operator fatigue during extended milling operations. At 2475 pounds, the 690093 is a substantial, floor-standing unit intended for permanent or semi-permanent installation in a professional machine shop setting. Licensed machinists and tool-and-die professionals are the primary operators of this equipment.

The JTM-4VS platform is suited to vertical milling operations including face milling, end milling, drilling, and boring on ferrous and non-ferrous materials. The 3-axis C80 DRO package provides real-time positional readout on three axes, supporting repeatable setups and tight-tolerance work. The integrated TPFA delivers powered longitudinal feed on the X-axis, making it appropriate for production runs and longer surface cuts where manual table travel would be impractical.

Key Features

• C80 3-axis digital readout covering knee, X, Y, and Z axes for real-time positional feedback
• Tilting Power Feed Assembly (TPFA) for powered X-axis table travel
• JTM-4VS vertical knee mill platform designed for toolroom and job shop use
• Robust cast iron construction supports precision milling on ferrous and non-ferrous materials
• Substantial 2475-pound machine mass provides rigidity and vibration damping during cuts

Compatibility

Designed as a factory-configured package for the JET JTM-4VS vertical knee mill platform with the C80 DRO and TPFA options included. Consult JET documentation to verify tooling, collet, and accessory compatibility specific to this machine configuration.

Installation Notes

Installation of a vertical knee mill of this class requires qualified riggers and appropriate lifting equipment rated for loads exceeding 2475 pounds. The machine must be leveled on a reinforced concrete floor using a precision machinist level before initial operation. Electrical connection should be performed by a licensed electrician in accordance with NEC requirements for the voltage and phase configuration of the unit. Verify all axis locks, lubrication points, and DRO wiring connections before powering the machine for the first time.
