JPW Industries (JET Machinery) JTM-4VS 690182 VERTICAL MACHINING CENTER

This vertical machining center features a 49" long by 9" wide table capable of supporting workpieces up to 660 lbs, suitable for medium-duty machining tasks. It is equipped with a vertical spindle featuring an R8 taper, facilitating compatibility with standard R8 tooling. The spindle operates at up to 4,200 RPM powered by a 3 HP motor rated for 30-minute duty cycles, enabling efficient material removal and surface finishing. The machine offers three axes of movement with a maximum Y-axis travel of 12" and Z-axis travel of 5", allowing for versatile positioning and machining capability within a compact 3-axis manual control configuration. Tool changes are manual with a single tool capacity, optimized for setups requiring straightforward tool handling without automatic tool changer complexity. The spindle taper is designed according to the R8 standard, which is characterized by a 3.5 inches per foot (approximately 16.26 degrees) taper angle, ensuring secure tool retention via a drawbar mechanism. This taper allows for effective rigidity and precision, suitable for a variety of milling operations. Rapid traverse rates are unspecified, but the machine supports manual control feeds for detailed operations. Overall, this machining center combines a robust worktable, moderate spindle power, and standard R8 tooling compatibility in a manual 3-axis vertical milling platform tailored for small to medium shop environments requiring precision and flexibility in milling applications.
