Frequently Asked Questions

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

The JTM-949EVS provides an electronic variable speed (EVS) spindle range of 60 to 4,500 RPM, controlled through a Delta B inverter. This wide range allows operators to dial in the optimal cutting speed for a variety of materials and tooling sizes without manual belt changes.

How does the automatic oiler system work on this mill?

The automatic oiler releases 3 to 6 cc/cy of lubrication every 30 minutes during operation. This ensures that ways, slides, and other critical moving components receive consistent lubrication automatically, reducing wear and the need for manual oiling intervals.

What measures are taken to protect spindle bearing and motor life on the JTM-949EVS?

The spindle head is internally cooled, which directly extends bearing, belt, and motor life by dissipating heat generated during cutting operations. Additionally, Class 7 spindle bearings are used to support the spindle for maximum rigidity, particularly in heavy cutting applications.

What makes the table and ways on this mill particularly accurate and durable?

The table and ways are hardened up to 54 HRC and precision ground for greater accuracy. Furthermore, the X-Axis and Y-Axis are coated with Turcite-B, which reduces vibration and promotes smooth, consistent movements - contributing directly to improved surface finish and dimensional accuracy in machined parts.
