Frequently Asked Questions

What spindle taper does the JET JVM-836-1 use, and why does it matter?

The JVM-836-1 uses an R-8 spindle taper, which is the most widely adopted standard in knee-mill milling machines. This means you'll have access to an extensive range of compatible collets, end mill holders, and tooling. The collet capacity spans 1/8" to 7/8", giving you flexibility across a broad selection of cutting tools.

How many spindle speeds are available, and what is the RPM range?

The JVM-836-1 offers 5 spindle speeds via its step pulley configuration, with a range spanning from 240 to 1,550 RPM. This range allows operators to select appropriate speeds for different materials and tooling diameters, from slower speeds for larger cutters or harder materials to faster speeds for smaller end mills in softer stock.

What are the power requirements for the JVM-836-1?

The machine is powered by a 1-1/2 HP motor rated for 115/230V, 1-Phase electrical service. The dual voltage capability provides flexibility for shops with either standard 115V outlets or 230V dedicated circuits, making installation straightforward in a variety of workshop environments.

What warranty coverage comes with the JET JVM-836-1?

The JET JVM-836-1 is backed by the JET Red Assurance 2-Year Warranty, which is one of the most comprehensive warranty programs in the industry for equipment of this class. This coverage reflects JET's confidence in the machine's build quality and long-term reliability.
