JET JTM-1 Mill with 3-Axis Newall DP500 DRO (Quill) with X & Y-Axis Powerfeeds is a precision vertical knee mill engineered by JET for machinists and shops demanding accuracy, durability, and versatile milling capability. Built on Certified Meehanite castings for rugged stability, this step pulley R-8 mill pairs a three-stage power down feed with automatic stop, high-precision Class 7 spindle bearings, and a factory-installed 3-axis Newall DP500 DRO with quill readout - giving operators real-time positional data and repeatable results on every cut. X and Y-axis powerfeeds further extend productivity, while the internally cooled spindle head prevents seizing during demanding operations. Backed by the industry-leading JET Two Year Warranty, the JTM-1 delivers professional-grade performance.

Frequently Asked Questions

What DRO system comes installed on this mill, and what axes does it cover?

This mill comes equipped with a 3-axis Newall DP500 DRO that includes a quill readout, providing real-time positional feedback on the X, Y, and quill (Z) axes for precise, repeatable machining without manual calculation.

What is the spindle speed range, and how many speeds are available?

The JTM-1 step pulley mill offers 16 spindle speeds ranging from 80-5,440 RPM, allowing operators to select the appropriate cutting speed for a wide variety of materials, tooling diameters, and milling operations.

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

The base features an internal coolant tank built in 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 machine?

The JTM-1 provides three selectable quill down feed rates - .0015, .003, and .006 IPR - via its three-stage power down feed mechanism, which also includes an automatic stop feature for controlled, repeatable depth drilling and boring operations.
