Frequently Asked Questions

What type of spindle taper does the JET JVM-836-1 use?

The JVM-836-1 uses an R-8 spindle taper, which is a widely adopted standard in vertical knee mills, offering broad compatibility with collets, end mill holders, and other R-8 tooling. Collet capacity ranges from 1/8 to 7/8 inch.

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

The mill features 5 spindle speeds with a range of 240 to 1,550 RPM, achieved via a step pulley drive system. This range accommodates a variety of materials and cutting tool diameters from roughing to finishing operations.

What does the one-shot lubrication system do?

The one-shot lubrication system allows the operator to deliver oil to all critical ways and moving surfaces with a single action. This simplifies routine maintenance, helps protect precision ground dovetail ways from wear, and supports consistent long-term machine performance.

Can the milling head be tilted for angular work?

Yes. The milling head tilts both left and right, enabling angular milling setups without repositioning the workpiece. The graduated scale on the column provides a reliable reference for vertical positioning during these and other setup adjustments.
