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 driven by a Delta B inverter, providing a continuously variable spindle speed range of 60 to 4,500 RPM. This allows the operator to fine-tune cutting speeds for a wide variety of materials and operations without changing belts manually.

How does the automatic oiling system work on this mill?

The automatic oiler releases 3 to 6 cc/cy of lubrication every 30 minutes, ensuring that all critical sliding and rotating components receive consistent lubrication during operation. This reduces wear and helps maintain long-term accuracy and machine longevity.

What makes the table and ways on the JTM-949EVS particularly accurate and durable?

The table and ways are hardened up to 54 HRC and precision ground for greater accuracy. Additionally, the X-Axis and Y-Axis are coated with Turcite-B for reduced vibration and smooth movements, contributing to superior surface finish quality and dimensional repeatability during machining.

What operator convenience and safety features are included on this machine?

The JTM-949EVS includes a swing away control box that houses an e-stop and puts all controls at the operator's fingertips, along with a swing away safety shield. The electrical box has been relocated to the back of the mill and houses two 115 outlets for powered accessories, keeping the work area organized and accessible. Dual locks on all moveable surfaces provide added stability and control during precision operations.
