JET JTM-4VS/690107 Mill – Acu-Rite 203 DRO, X-Axis Powerfeed, VS

Description

JET JTM-4VS/690107 Variable Speed Vertical Milling Machine

The JET JTM-4VS/690107 vertical mill accelerates high-precision toolroom machining and custom component manufacturing across demanding industrial metal fabrication facilities. This heavy-duty 3 horsepower mill resolves complex metalworking bottlenecks by integrating an Acu-Rite 203 Digital Readout (DRO) system with an automated X-axis powerfeed mechanism. Machinists can seamlessly execute long longitudinal passes and continuous boring cycles without experiencing manual handling errors or micro-calibration drift. The specialized precision bored and honed milling head design ensures incredibly smooth cuts across a vast 9 by 49 inch worktable layout, removing tool room chatter delays from your daily metallurgical production workflows.

Built to remain completely rigid under intense industrial torque forces, this massive 2420-pound machining center utilizes a solid cast iron frame to absorb destructive tool vibrations. An infinitely variable speed mechanical gearbox drives the spindle smoothly from 60 to 4200 RPM, matching exact cutting parameters for soft alloys or hardened tool steels. The system features an automated 3-stage power downfeed with an automatic stop mechanism to control deep hole vertical strokes up to 5 inches safely. Operating on a versatile 230V or 460V three-phase electrical supply, this extensive toolroom platform maximizes workshop output, providing fabrication lines a highly rigid, reliable asset for complex industrial parts processing.
