Manford CB-170 VERTICAL MACHINING CENTER

This vertical machining center features a work table measuring 54.0 inches in length by 10.0 inches in width, capable of supporting workpieces up to 950 pounds. It is equipped with a vertical spindle utilizing an R-8 taper, with an optional #30 taper possible. The spindle operates at a maximum speed of 4,500 RPM and is powered by a 3.00 horsepower motor rated for 30-minute intervals. Tooling is manual, supporting a single tool with zero tool change chip time, emphasizing manual tool swapping. The machine operates on three axes (X, Y, and Z) with travel capacities of 31.0", 19.0", and 5.0" respectively. Each axis can feed at a maximum and rapid traverse rate of 240 inches per minute (ipm). The spindle taper, R-8, corresponds to a specific standardized taper angle of approximately 16.26 degrees and is widely used in machining center applications for its secure tool holding via a drawbar mechanism. The combination of a sizable table, substantial load capacity, moderate spindle power, and manual tooling makes this machine well-suited for versatile vertical milling operations involving medium to heavy workpieces with precision positioning in all three axes. The rapid traverse and feed rates are balanced for controlled yet efficient material removal and machining productivity. This setup is ideal for workshops requiring robust, precise vertical milling without automated tool changing or complex multi-tool fixtures.
