Southwestern Industries, Inc. TRAK K3E VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a robust table measuring 50" long by 10" wide, capable of supporting workpieces up to 850 lbs, ideal for medium-duty machining tasks. The machine is equipped with a single spindle oriented vertically, featuring an R8 taper for compatibility with standard tooling. The spindle is powered by a 3.0 HP motor (30-minute rating), delivering up to 4,200 RPM for versatile machining speeds. Tooling is manual with one tool station, ensuring simplicity and reliability in tool setup and change. The machine operates on two axes, with travels of 32" along the X-axis, 16" along the Y-axis, and 16" along the Z-axis, providing ample range for a variety of milling operations. These axes support precise movement, but feed rates and rapid traverse speeds are unspecified, likely variable per application. The absence of a U axis indicates no rotary axis capability, focusing on two-dimensional milling profiles. The R8 spindle taper, approximately a 16.26° angle, is traditionally used in machining centers, offering secure and precise tool holding via a drawbar mechanism. The spindle design supports high rigidity and minimal runout, critical for precision machining. The manual tool carrier and the machine's relatively compact size make it suitable for shop floors requiring reliable vertical milling with moderate complexity and load demands.
