TSUGAMI/ REM SALES BU20 HORIZONTAL MACHINING CENTER

Technical Description

The Tsugami/Rem Sales BU20 is a horizontal Swiss-style turning center engineered for precision small-parts manufacturing with exceptional capability. Featuring a main spindle with 0.790" maximum turning diameter and 6.690" length capacity, combined with a dedicated sub-spindle offering identical 0.790" diameter and 3.140" length capacity, this machine enables simultaneous front and back machining operations. Both main and sub-spindles operate at 8,000 RPM with 5.00 HP each, minimizing vibration through integral built-in designs for superior geometric and dimensional accuracy. The machine combines dual tool carriers—a slide with 4 turning tools and 3 rotary tools (0.66 HP at 8,000 RPM), and a turret with 8 turning tools and 4 rotary tools (1.33 HP at 6,000 RPM)—allowing simultaneous deployment of up to 2 cutting tools. Its 8-axis CNC architecture includes programmable Y-axis and C-axis capabilities, providing on-center, off-center, and cross-drilling functionality. Linear motion across X, Y, and Z axes delivers rapid traverse rates of 472 ipm with maximum feed rates of 236 ipm, supported by generous axis travels of 1.220", 2.780", and 7.870" respectively. The CNC control system ensures enriched NC functions including tool nose radius compensation and cutoff detection. This configuration makes the BU20 ideal for complex, multi-sided part production in single setups, combining traditional Swiss turning precision with modern turret flexibility for demanding job-shop applications.
