JPW Industries (JET Machinery) JMD-18PFN VERTICAL MACHINING CENTER

This vertical machining center features a rigid work table sized 31.75 inches long by 9.5 inches wide, supporting a maximum workpiece weight of 250 lbs. It is equipped with a vertically oriented spindle using the standard R8 taper, providing a top spindle speed of 2,500 RPM driven by a 2.0 HP motor rated for 30 minutes. The machine supports manual tooling with a single tool carrier, facilitating straightforward tool changes without chip time delay. Its motion system includes four axes, with specified travels of 7 inches in the Y-axis and 5 inches in the Z-axis, enabling precise vertical and lateral milling operations. The spindle taper angle approximates 16.26 degrees, following Bridgeport's R8 taper standard, which facilitates secure tool holding via a drawbar mechanism, ensuring rigidity and accuracy during machining. The machine’s design is suited for moderate size and weight workpieces, ideal for precise vertical milling and drilling tasks requiring reliable spindle power and versatility. The manual tool carrier and single tool capacity make it suitable for setups emphasizing controlled, precise single-tool operations rather than rapid tool changes or high-volume automated machining. Overall, this machining center balances compact size, moderate power, and precise manual control in vertical spindle milling applications.
