Frequently Asked Questions

What spindle taper does the JTM-2 use, and what collet sizes are compatible?

The JTM-2 uses an R-8 spindle taper, which is one of the most widely supported tapers in vertical milling. It accepts collets ranging from 1/8 to 7/8 inch, giving you broad tooling compatibility for a variety of milling and drilling operations.

Does the JTM-2 include a coolant pump with the internal coolant tank?

The machine features an internal coolant tank built into the base for use with a coolant system; however, the coolant pump is not included and must be sourced separately.

What are the three quill down feed rates available on this mill?

The three stage power downfeed system on the JTM-2 offers feed rates of .0015, .003, and .006 inches per revolution (IPR), allowing you to dial in the appropriate feed rate for the material and tool being used. An automatic stop is also included for repeatable depth control.

How does the X-axis powerfeed affect the usable table travel?

With the X-axis powerfeed engaged, the table longitudinal travel is 20-2/7 inches. Without the powerfeed, the full table longitudinal travel extends to 23-7/8 inches. The powerfeed automates table movement along the X-axis for consistent feed rates throughout the cut.
