  • Bridgeport 2J low speed troubles - Practical Machinist

    Apr 22, 2019 · Hey! I just traded some other equipment for a Bridgeport 2J mill. I've always wanted one. This one works great in high speed but in low speed in makes kind of a light growling almost like a bad bearing and has low torque. It will actually pull quite a bit harder in high speed at 500 RPM than it will at 100 RPM in low speed.
