JET EVS-1440 Electronic Variable Speed Lathe with Taper Attachment, 3HP from JET delivers precision metal turning capability with electronic variable speed control, making it a powerful solution for professional machinists and production shops demanding consistent, repeatable results. Built on a V-Way bed that is induction hardened and ground, this lathe is engineered for long-term rigidity and tolerance retention. The D1-4 spindle is precision ground for accuracy and supported by class 7 tapered roller bearings capable of a run-out maximum of .0004". An apron-mounted actuation control and jog button provide easy gear engagement and spindle inching, while the two-speed gearbox enables operation at low speeds from 40-365 RPM and high speeds from 220-2,000 RPM. Meehanite castings ensure the machine retains its tolerance and remains rigid over many years of machining.

Frequently Asked Questions

What speed ranges does this lathe support?

The lathe features a two-speed gearbox. The low speed range runs from 40-365 RPM and the high speed range runs from 220-2,000 RPM. The LED RPM readout allows operators to monitor turning speed precisely at all times.

What power supply is required to run this lathe?

This lathe requires a 3-phase electrical supply. The motor is rated at 3 HP, 230V, 3-Phase. Ensure your facility has the appropriate 3-phase service before installation.

Does this lathe support both inch and metric threading?

Yes. The lathe provides 34 inch thread pitches ranging from 2-56 TPI and 34 metric thread pitches with a range starting at 0.5. The Threading Dial Indicator and independent lead screw and feed rod support accurate and efficient thread cutting in both systems.

How does the backlash elimination on the compound and cross slide benefit machining?

Backlash elimination on both the compound and cross slide removes unwanted play from the handwheel mechanisms, allowing operators to achieve precise, repeatable tool positioning. This is especially important during finishing passes and close-tolerance work where even small positional errors can affect part quality.
