Frequently Asked Questions

What spindle taper does the JTM-1 use, and what is the collet capacity range?

The JTM-1 uses an R-8 spindle taper, which is one of the most common and versatile standards in vertical knee milling. The collet capacity ranges from 1/8-7/8 inch, accommodating a wide variety of tooling for different cutting applications.

Does this mill include a coolant pump with the internal coolant tank?

The JTM-1 features 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 are the available quill down feed rates, and how does the power downfeed work?

The quill offers three stage power downfeed rates of .0015, .003, and .006 inches per revolution (IPR), with an automatic stop feature that allows you to set a precise depth and have the downfeed disengage automatically - ideal for repeatable drilling and boring operations.

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

The JTM-1 provides 8 spindle speeds with a range of 80-2,720 RPM via its step pulley drive system, giving you the flexibility to match cutting speed to a wide variety of materials and tooling diameters.
