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 supported standards in manual vertical milling. Collet capacity ranges from 1/8 to 7/8 inch, providing broad tooling compatibility for end mills, drills, and other common cutting tools.

Does this mill include a coolant pump?

The JTM-1 features an internal coolant tank built into the base that is ready for use with a coolant system; however, the coolant pump is not included and must be sourced separately.

What power supply is required to operate the JTM-1?

The JTM-1 is powered by a 2 HP motor rated at 230V, 3-phase. Ensure your facility has an appropriate 3-phase electrical supply before installation.

How is spindle accuracy verified before the mill leaves the factory?

Each JTM-1 ships with a tolerance test sheet confirming that the machine has been inspected and meets specified accuracy standards. The precision bored and honed milling head, combined with high precision Class 7 spindle bearings, ensures consistent, repeatable performance right out of the box.
