Frequently Asked Questions

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

This mill comes equipped with a 3-axis Newall DP700 Digital Readout on the quill. In addition, powerfeeds are included on both the X and Y axes, giving the operator precise, motorized table movement and accurate digital position feedback during machining operations.

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 the industry-standard configuration. It accepts collets ranging from 1/8 inch to 7/8 inch, making it compatible with a wide variety of commonly available tooling.

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

The mill features 8 spindle speeds with a range of 80 to 2,720 RPM. This broad range allows machinists to select the appropriate speed for different materials, cutter diameters, and cutting conditions.

Does the JTM-2 include a coolant system, and what should I know about the coolant setup?

The JTM-2 has 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. The built-in tank provides a convenient, integrated foundation for adding a coolant system to the machine.
