Country of Origin: Taiwan Prop 65: Cancer and Reproductive Harm Frequently Asked Questions What spindle taper does the JET JTM-1254VS use, and what is its collet capacity? The JTM-1254VS uses an NST #40 spindle taper and accepts collets ranging from 1/8" to 1" in diameter, making it compatible with a wide variety of tooling for diverse milling applications. Does this mill include powerfeeds, and what power is provided for them? Yes, this model includes X, Y, and Z powerfeeds. The electrical box features two dedicated 115V outlets specifically for powerfeed use, ensuring a clean and integrated electrical setup. How does the pneumatic power drawbar work on this machine? The air (pneumatic) power drawbar allows for fast, hands-free tool changes by using compressed air to engage and release the drawbar mechanism, significantly reducing downtime between tool changes compared to a manual drawbar. What motor power and electrical requirements does the JTM-1254VS require? The JTM-1254VS is powered by a 5HP motor requiring 230/460V, 3-phase electrical service. This three-phase configuration delivers the consistent torque and power needed for heavy-duty milling operations across the full 80 - 3,800 RPM variable speed range.
