JPW INDUSTRIES (JET MACHINERY) JMD-15 VERTICAL MACHINING CENTER

This vertical machining center features a robust 23" x 7.5" work table supporting up to 250 lbs, ideal for medium-duty machining tasks. It incorporates a vertical spindle with an R8 taper, standard in many toolroom mills, facilitating secure and precise tool holding via a manual drawbar system. The spindle runs up to 2,580 RPM, powered by a 1.0 HP motor rated for 30-minute duty cycles, suitable for various milling and drilling operations. This single-tool setup includes manual tool loading and zero tool change chip time, emphasizing simplicity and reliability. The milling work envelope consists of 4 axes overall, with defined travels of 6.0" along the Y-axis and 3.5" along the Z-axis, enabling precise vertical and transverse cutting motions, although no U axis is provided. Rapid traverse rates and maximum feed are configured to optimize machining efficiency within these travel limits. The R8 spindle taper has an approximate angle of 16.26 degrees (3.5" per foot taper), enabling versatility with common collets and tooling tailored for toolroom milling applications. This machine's size and power make it suitable for detailed metalworking tasks such as die and mold work, prototype fabrication, and small-batch manufacturing where moderate spindle speed and workpiece capacity suffice. The manual tool carrier and straightforward controls provide an accessible platform for skilled operators requiring accuracy and flexibility without automated tool changes or multi-tool capabilities. Overall, this vertical mill combines moderate workpiece capacity, a classic R8 spindle taper, and manageable tooling for efficient, precise milling in a compact footprint.
