Jet 690178 Variable Speed Vertical Mill

Product Description

The JET 690178 is a variable speed vertical milling machine designed for professional machining applications in industrial and trade shop environments. The JTM-4VS-1 configuration delivers variable spindle speed control, allowing machinists to match cutting speed to the workpiece material and tooling requirements. At 2,250 pounds, this is a full-size knee mill built for stationary floor installation in a machine shop setting. It is intended for installation and operation by qualified machinists and toolroom professionals working with metal fabrication, precision parts production, and general machining tasks.

This mill is suited for industrial shops, vocational training facilities, and professional machine shops requiring a full-size vertical knee mill. The variable speed drive eliminates the need for manual belt changes when adjusting spindle RPM, making it practical for production environments where operators switch between different materials and tooling setups frequently. Its weight and footprint are consistent with permanent floor-mounted installation.

Key Features

• Variable spindle speed control for flexible material and tooling compatibility
• Full-size vertical knee mill configuration suitable for floor-mounted shop use
• Substantial 2,250 pound construction for rigidity and vibration damping during cuts
• JTM-4VS-1 platform built for stationary industrial machining environments

Compatibility

Designed as an OEM-direct unit matching the JTM-4VS-1 vertical knee mill specification. No additional compatible model or replacement part information was provided in the product data.

Installation Notes

Installation of a floor-mount knee mill of this class requires a qualified millwright or mechanical contractor and a suitably reinforced concrete floor capable of supporting the machine weight. The machine must be leveled using precision levels before commissioning. Electrical connection should be performed by a licensed electrician in accordance with NEC requirements for the applicable voltage and phase configuration. Always isolate and lock out all power sources before performing any service, tooling changes, or adjustments to the machine.
