Frequently Asked Questions

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

The JTM-1 uses an R-8 spindle taper, one of the most common tapers for vertical knee mills, offering wide tooling compatibility and straightforward tool changes.

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

The JTM-1 features 16 spindle speeds with a range of 80 to 5,440 RPM, providing versatility to machine a broad variety of materials from steel to aluminum and plastics.

Is a coolant pump included with the machine?

The machine includes an internal coolant tank built into the base designed for use with a coolant system; however, the coolant pump is not included and must be sourced separately.

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

The JTM-1 offers three-stage power down feed with quill down feed rates of .0015, .003, and .006 inches per revolution (IPR), along with an automatic stop for precise depth control.
