Frequently Asked Questions

What spindle speed range does the JTM-1050EVS2/230 offer, and how is speed controlled?

The JTM-1050EVS2/230 features an Electronic Variable Speed (EVS) drive with a Delta B inverter that provides a continuous spindle speed range of 60-4,500 RPM. This EVS system allows the operator to dial in the precise speed needed for any material or cutting operation without the need to change belt positions for every adjustment.

What is Turcite-B coating, and why is it used on the X-Axis and Y-Axis?

Turcite-B is a high-performance bearing material applied to the X-Axis and Y-Axis ways. Its use on this mill reduces vibration and ensures smooth, consistent table movements, which directly contributes to improved surface finish quality and extended machine life compared to uncoated cast iron ways.

How does the automatic oiler work on this mill?

The automatic oiler is designed to release 3 to 6 cc/cy of lubrication at adjustable time intervals. This ensures that all critical sliding surfaces receive consistent lubrication automatically during operation, reducing wear and the need for manual oiling by the operator.

What electrical accessories does the JTM-1050EVS2/230 support, and what power requirements are needed?

The mill runs on 230V, 3-phase power with a 3 HP motor. The electrical box, which has been relocated to the back of the mill, houses two 115-volt outlets that can be used to power accessories such as a DRO display or task lighting. The included Acu-Rite 203 DRO and pneumatic air powered drawbar add measurement precision and faster tool-change capability right out of the box.
