JET JTM-1 Mill with 3-Axis Newall DP700 DRO (Quill) with X-Axis Powerfeed is a precision vertical milling machine engineered by JET for demanding machining environments where accuracy, repeatability, and long-term reliability are non-negotiable. Equipped with a 3-axis Newall DP700 digital readout on the quill and an X-axis powerfeed, this step-pulley R-8 mill delivers 16 spindle speeds ranging from 80-5,440 RPM, making it equally capable of tackling roughing cuts and fine finishing work. Certified Meehanite castings provide the rugged, vibration-dampening foundation that serious machinists demand, while Class 7 spindle bearings and a precision bored and honed milling head ensure consistent, high-quality results backed by the industry-leading JET Two Year Warranty.

Frequently Asked Questions

What type of digital readout is included with this mill, and how many axes does it cover?

This mill comes equipped with a 3-axis Newall DP700 DRO configured for the quill. It covers three axes and is designed to eliminate manual measurement errors, significantly reducing setup time and improving positional accuracy across all milling operations.

Does this machine include a coolant pump?

The JTM-1 features an internal coolant tank built directly into the base, which is designed for use with a coolant system. However, the coolant pump is not included with the machine and must be sourced separately.

What spindle taper does the JTM-1 use, and what collet sizes are compatible?

The JTM-1 uses an R-8 spindle taper, which is one of the most widely used standards in vertical milling. It accepts collets ranging from 1/8-7/8 in., giving machinists a broad selection of compatible tooling for a wide variety of milling tasks.

How does the one shot lubrication system benefit the machine during operation?

The one shot lubrication system allows the operator to deliver lubricant to all critical moving components simultaneously with a single action. This ensures the precision hardened and ground ways and other wear surfaces remain properly lubricated, extending machine life and maintaining accuracy over years of heavy use.
