1988 MIYANO TSV21 VERTICAL MACHINING CENTER

Technical Description

The 1988 Miyano TSV21 is a 3-axis drill-and-tap center from Miyano's TSV series, designed for high-speed, high-volume production drilling, tapping, and light milling of small precision components. The TSV21 features a 20 x 8.66 inch work table and provides X-, Y-, and Z-axis travels of 11.81, 8.66, and 7.87 inches, optimized for the rapid machining of compact workpieces such as electronic enclosures, hydraulic fittings, small brackets, and connectors. The No. 30 (BT-30) taper spindle reaches speeds of 8,000 RPM, enabling high surface speed for aluminum and non-ferrous components while maintaining fast drilling and tapping cycles. Rapid traverse rates of 472 IPM on X and Y and 394 IPM on Z contribute to short non-cutting times between features. The machine is equipped with the Fanuc 0M CNC control, providing G-code programming, rigid tapping, and standard canned cycles. Table load capacity is 110 pounds. As a 1988 vintage machine, the TSV21 has significant operating history and is best evaluated based on spindle condition and control functionality. Miyano drill-and-tap centers of this era were widely used in Japanese and North American high-volume precision production environments.
