Frequently Asked Questions

What type of spindle taper does the JTM-1 use?

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

Does this mill include a coolant pump?

The JTM-1 features an internal coolant tank built directly into the base, which is designed for use with a coolant system. However, the coolant pump is not included and would need to be sourced separately.

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

This mill offers 16 spindle speeds with a range of 80-5,440 RPM via a step pulley drive system, allowing the operator to select the appropriate speed for a wide variety of materials and cutting tool diameters.

What lubrication system does the JTM-1 use, and how does it protect the machine?

The JTM-1 is equipped with a one shot lubrication system, which delivers oil to all critical wear points - including the precision hardened and ground ways - with a single pump stroke. This simplifies routine maintenance and helps extend the service life of the machine's precision components.
