Frequently Asked Questions

What voltage and phase requirements does the JET JVM-836-3 require?

The JVM-836-3 requires 230V, 3-phase power. It is not compatible with single-phase electrical service, so a 3-phase power supply must be available in your facility before installation.

What is the spindle taper and collet capacity on this milling machine?

The JVM-836-3 features an R-8 spindle taper with a collet capacity range of 1/8 to 7/8 inch, making it compatible with the widely available R-8 tooling system standard in most professional shop environments.

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

This step pulley mill offers 10 spindle speeds with a range spanning 120 to 1,550 RPM, providing the versatility needed to mill a variety of materials and workpiece sizes at the appropriate cutting speed.

What warranty does the JET JVM-836-3 carry?

The JET JVM-836-3 is backed by the industry-leading JET Two Year Warranty, providing coverage and peace of mind for professional users who depend on this machine in daily production environments.
