Frequently Asked Questions

What type of spindle taper does the JET JTM-2 use?

The JET JTM-2 uses an R-8 spindle taper, which is a widely used standard in vertical knee mills. The collet capacity ranges from 1/8 to 7/8 inch, providing compatibility with a broad range of tooling.

What are the available quill down feed rates on this mill?

The JTM-2 features three stage power downfeed with automatic stop. The available quill down feed rates are .0015, .003, and .006 inches per revolution (IPR), giving operators control over feed rate to match different materials and tooling requirements.

Is a coolant pump included with this machine?

The JTM-2 includes an internal coolant tank built into the base for use with a coolant system; however, the coolant pump is not included and must be purchased separately.

What digital readout system comes with this mill, and how many axes does it cover?

This mill is equipped with an ACU-RITE 203 Digital Readout (DRO) covering 2 axes, paired with X and Y-axis powerfeeds. This combination provides real-time position feedback and powered table movement for accurate, repeatable machining operations.
