WILLIS MACHINERY & TOOLS 1050 II VERTICAL MACHINING CENTER

This vertical machining center features a 50" x 10" work table capable of supporting workpieces up to 750 lbs. It is equipped with a vertical spindle featuring an R8 taper and an optional #30 taper for tooling compatibility. The spindle delivers up to 3 HP (30-minute rating) and operates at speeds up to 4,200 RPM, providing sufficient power and speed for a range of milling operations. The machine supports manual tool carrier operation with one tool capacity and an instantaneous tool change chip time. It operates with 5 axes: Z-axis travel of 5.000 inches, rotational A-axis travel of 180°, and B-axis rotation up to 360°, allowing for multi-axis positioning and complex machining capabilities. The machine does not have a U-axis travel. Rapid traverse and max feed rates for axes X, Y are unspecified. The spindle taper (R8) is a standardized 3.5 inches per foot taper angle, approximately 16.26 degrees, widely used for precision tool holding in machining centers. The manual tool carrier with a single tool holder limits automation but enables straightforward operation. Overall, the machine is designed for moderate-size workpieces and versatile milling tasks, balancing manual control with 5-axis movement to facilitate intricate machining on vertical setups. Its sturdy table and spindle specifications make it well-suited for precision metalworking applications within a workpiece weight limit of 750 lbs.
