Frequently Asked Questions

What spindle speed range does the JTM-1 support, and how many speeds are available?

The JTM-1 offers 16 spindle speeds ranging from 80-5,440 RPM, providing versatility to handle a wide variety of materials, tooling sizes, and milling operations from heavy roughing cuts to fine finishing passes.

Does this mill include a coolant system?

The JTM-1 features an internal coolant tank built into the base for use with a coolant system; however, the coolant pump is not included and would need to be added separately.

What DRO and powerfeed are included with this mill?

This mill comes equipped with the ACU-RITE 203 DRO for precise 2-axis digital position readout and an X-Axis Powerfeed for automated, consistent longitudinal table movement, enhancing both accuracy and operator efficiency.

What spindle taper does the JTM-1 use, and what is the collet capacity?

The JTM-1 uses an R-8 spindle taper, which is one of the most common and widely supported tapers in manual milling. The collet capacity ranges from 1/8-7/8 inch, accommodating a broad selection of standard tooling.
