Jet 690158 Vertical Knee Mill 3-axis Dro X-axis Powerfeed

Product Description

The JET 690158 is a vertical knee mill configured with a factory-installed 3-axis ACU-RITE 200S digital readout (DRO) and an X-axis powerfeed. The ACU-RITE 200S DRO provides real-time position feedback on all three axes, reducing manual measurement steps and improving repeatability on production and toolroom work. The integrated X-axis powerfeed automates table travel, reducing operator fatigue on long cuts. At 2900 pounds, this is a full-size knee mill intended for machine shops, maintenance facilities, vocational training centers, and industrial toolrooms requiring precision milling capability.

This mill is suited for ferrous and non-ferrous metal machining operations including face milling, end milling, drilling, and boring. It is appropriate for small-batch production, prototype work, and repair machining environments. The factory-installed DRO and powerfeed reduce setup time compared to field-retrofitted configurations. Installation typically requires a prepared concrete floor, anchor hardware, and proper three-phase or single-phase electrical service depending on the motor configuration supplied.

Key Features

• Factory-installed ACU-RITE 200S DRO with 3-axis position readout for accurate, repeatable setups
• X-axis powerfeed installed at the factory for consistent table feed rates and reduced operator fatigue
• Full-size vertical knee mill construction at 2900 pounds for rigidity during heavy cuts
• Sold as a complete, ready-to-run unit — no field DRO wiring or powerfeed mounting required

Compatibility

Designed as a self-contained machine tool; the ACU-RITE 200S DRO and X-axis powerfeed are factory-matched to the JTM-1050 knee mill platform. Replacement or additional accessories should be specified for the JTM-1050 column and table configuration.

Installation Notes

Millwrights or qualified machinery installers should handle delivery and placement of this machine due to its 2900-pound shipping weight. A forklift or overhead crane with adequate rated capacity is required for positioning. The machine must be leveled on a reinforced concrete floor and secured per the manufacturer instructions before operation. Electrical connection must be performed by a licensed electrician in accordance with applicable NEC requirements for the motor voltage and phase configuration.
