Frequently Asked Questions

What DRO system is included with this mill, and how many axes does it cover?

This mill comes equipped with a 3-axis Newall DP700 DRO configured for the quill, giving the operator precise digital position readout across three axes for improved accuracy and reduced setup time.

What are the available quill downfeed rates and how does the automatic stop work?

The three-stage power downfeed system offers rates of .0015, .003, and .006 inches per revolution. The automatic stop feature allows the operator to preset a depth, and the downfeed will disengage automatically when that depth is reached, enabling consistent and repeatable results.

Is a coolant pump included with the built-in coolant tank?

The base of the mill includes an internal coolant tank designed for use with a coolant system; however, the coolant pump is not included and must be sourced separately.

What spindle taper does this mill use, and what collet sizes are compatible?

The JTM-2 uses an R-8 spindle taper, which is one of the most widely used standards in knee mills. It accepts collets ranging from 1/8 inch to 7/8 inch, providing compatibility with a broad selection of standard toolholding and workholding accessories.
