Acer ULTIMA 2S VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a 42" x 9" work table capable of supporting a maximum workpiece weight of 750 lbs, designed to handle medium to large machining tasks. It utilizes a vertical spindle with an R-8 taper, delivering up to 5,440 RPM powered by a 2.0 HP motor rated for 30 minutes, suitable for a variety of cutting operations requiring precision and moderate power. The spindle orientation is fixed vertically, with manual tool change capability, supporting a single tool at a time for straightforward, controlled machining. The machine operates on a 5-axis configuration, including linear travels of 20" in the Y-axis and 12" in the Z-axis, with rotational capabilities of 90° about the A-axis and 45° about the B-axis. Notably, the X-axis travel and feed rates are unspecified, but the rapid traverse speeds can be expected to optimize machining cycle times consistent with similar vertical mills. The R-8 spindle taper conforms approximately to a 16.6° included angle taper, providing compatibility with standard R-8 tooling known for accuracy and ease of tool setup. This mill is ideal for precise milling and drilling operations requiring moderate spindle power, manual operation, and flexible 5-axis machining, allowing angular positioning for complex workpieces. Its robust table size and load capacity accommodate substantial parts, while the manual tool carrier and fixed spindle taper ensure reliable tool holding and ease of use in workshop environments. The combination of rotary axes and vertical spindle configuration supports advanced machining strategies on medium scale projects.
