Frequently Asked Questions

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

The JTM-2 uses an R-8 spindle taper, the most widely adopted standard for vertical knee mills, ensuring broad compatibility with collets, end mill holders, and other R-8 tooling. The collet capacity ranges from 1/8 to 7/8 inch.

What are the available quill downfeed rates, and does the machine have an automatic stop?

The JTM-2 features a three-stage power downfeed with three selectable feed rates: .0015, .003, and .006 inches per revolution (IPR). An automatic stop is included, allowing you to set a precise depth and have the downfeed disengage automatically for repeatable results.

Is a coolant pump included with the built-in coolant tank?

The machine 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 sourced separately.

What lubrication system does the JTM-2 use, and what accuracy documentation is provided?

The JTM-2 is equipped with a one-shot lubrication system that simplifies routine maintenance and helps protect the precision hardened and ground ways. A tolerance test sheet is included with each machine, confirming that the unit has been inspected and meets JET's accuracy standards before shipment.
