Frequently Asked Questions

What spindle taper does the JTM-1 use, and what collet sizes are compatible?

The JTM-1 uses an R-8 spindle taper, which is one of the most widely used tapers in vertical knee milling machines. It accepts collets ranging from 1/8-7/8 inch, giving you broad compatibility with standard tooling.

Does this mill come with a coolant pump?

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

What is the power requirement for the JTM-1 with 3-axis Newall DP500 DRO?

This model is powered by a 2 HP motor running on 230V, 3-phase power. Ensure your shop electrical supply meets these requirements before installation.

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

The JTM-1 offers 16 spindle speeds with a range of 80-5,440 RPM via the step pulley drive system, providing the flexibility to machine a wide variety of materials and operations at optimal cutting speeds.
