Frequently Asked Questions

What spindle taper does the JTM-1254RVS use, and what is the collet capacity range?

The JTM-1254RVS uses an R-8 spindle taper with a collet capacity range of 1/8" to 1", making it compatible with a wide selection of commonly available tooling used in professional machine shops.

What are the available quill down feed rates on this mill?

The JTM-1254RVS features a three-stage power downfeed with automatic stop, offering quill down feed rates of .0015, .003, and .008 inches per revolution (IPR), allowing operators to select the appropriate feed rate for their specific material and operation.

What electrical power is required to operate this milling machine?

The JTM-1254RVS is powered by a 5HP motor requiring 230/460V, 3-phase electrical service. Additionally, two dedicated 115V outlets are located on the electrical box specifically for powering the X and Y axis Powerfeeds.

What is the full variable speed spindle range, and how does the pneumatic power drawbar benefit the operator?

The spindle operates across a variable speed range of 80 to 3,800 RPM, providing flexibility for milling a wide variety of materials and operations. The pneumatic (air) power drawbar allows for fast, effortless tool changes compared to manual drawbar methods, significantly reducing downtime between operations.
