Jet 690221 Vertical Mill 3-axis Dro X Powerfeed

Product Description

The JET 690221 is a JTM-4VS vertical knee mill equipped with a factory-installed 3-axis ACU-RITE 200S digital readout (DRO) on the quill and an X-axis powerfeed. Designed for precision metal removal in production and toolroom environments, this machine combines variable-speed spindle control with real-time positional feedback through the ACU-RITE 200S display. The integrated X powerfeed automates table travel on the horizontal axis, reducing operator fatigue during repetitive cuts. At 2,240 pounds, the JTM-4VS is a full-size knee mill built for professional machinists and metalworking shops requiring accuracy and repeatability across a wide range of milling operations.

The JET 690221 is suited for job shops, tool-and-die operations, maintenance departments, and vocational training environments. The JTM-4VS platform is a standard vertical knee mill configuration used for face milling, end milling, boring, and drilling on ferrous and non-ferrous materials. The factory-installed DRO and powerfeed make this configuration ready for productive work immediately upon installation, without requiring additional field retrofitting of positioning or feed equipment.

Key Features

• Factory-installed 3-axis ACU-RITE 200S DRO provides real-time X, Y, and quill position readout
• X-axis powerfeed installed at the factory for consistent, hands-free table travel
• Variable-speed (VS) spindle drive allows RPM adjustment without changing belts or gears
• Full-size knee mill construction at 2,240 pounds for rigidity and vibration damping during cuts
• Quill DRO integration supports precise depth-of-cut control on drilling and boring operations

Compatibility

Designed as a complete, self-contained vertical knee mill unit in the JTM-4VS product line. The ACU-RITE 200S DRO and X powerfeed are factory-installed components specific to this configured SKU.

Installation Notes

Installation of a machine at this weight class requires rigging equipment rated for the load and a level, reinforced concrete floor capable of supporting 2,240 pounds plus dynamic cutting forces. Electrical connection must be performed by a licensed electrician in accordance with applicable NEC requirements for the machine's voltage and phase configuration. Verify spindle alignment and table tramming before initial operation. Do not operate the machine until all shipping brackets and restraints have been removed per the manufacturer's installation documentation.
