Frequently Asked Questions

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

The JTM-949EVS features Electronic Variable Speed (EVS) control powered by a Delta B inverter, providing a continuous spindle speed range of 60 to 4,500 RPM. This allows operators to dial in the precise speed required for different materials and cutting conditions without changing belts manually.

What type of DRO and powerfeed configuration is included with this mill?

This machine comes equipped with a 3-Axis Newall DP700 Digital Readout configured for the Quill axis, along with X-Axis and Y-Axis Powerfeeds. This combination provides precise positional readout and powered table movement for improved accuracy and reduced operator fatigue during extended operations.

How does the JTM-949EVS protect its spindle and internal components during heavy use?

The mill uses Class 7 spindle bearings for maximum rigidity in heavy cutting applications, and the spindle head is internally cooled, which extends bearing, belt, and motor life. Additionally, the automatic oiler releases 3 to 6 cc/cy of lubrication every 30 minutes to keep critical moving components properly lubricated.

What measures does this mill incorporate to improve accuracy and reduce vibration?

The table and ways are hardened up to 54 HRC and precision ground for greater accuracy. The X-Axis and Y-Axis are coated with Turcite-B for reduced vibration and smooth movements. Dual locks on all moveable surfaces further stabilize the machine during cutting operations to maintain precise positioning.
