Frequently Asked Questions

What spindle speed range does the JTM-949EVS offer, and how is it controlled?

The JTM-949EVS features an electronic variable speed (EVS) system powered by a Delta B-series inverter, providing a spindle speed range of 60 to 4,500 RPM. This wide range allows operators to dial in the ideal cutting speed for a variety of materials and tooling diameters without changing belts manually.

How does the automatic oiler work on this mill?

The automatic oiler releases 3 to 6 cc/cy of lubrication every 30 minutes, consistently delivering oil to critical moving components throughout operation. This helps extend the service life of the ways, bearings, and other wear surfaces without requiring manual lubrication intervals.

What makes the table and ways on the JTM-949EVS suitable for precision work?

The table and ways are hardened up to 54 HRC and precision ground for greater accuracy. In addition, the X-Axis and Y-Axis are coated with Turcite-B for reduced vibration and smooth movements, contributing to improved surface finishes and more consistent dimensional results during milling operations.

Does this mill include a digital readout, and what axes does it cover?

Yes. This machine comes equipped with a 3-Axis Newall DP700 DRO configured for Quill operation, providing digital position readout on the X-Axis, Y-Axis, and Quill (Z-Axis). Combined with the X and Y-Axis powerfeeds and Class 7 spindle bearings for maximum rigidity, the DRO setup supports repeatable, high-accuracy machining across all three axes.
