Kiwa V21I-R VERTICAL MACHINING CENTER

This vertical CNC machining center features a CAT 40 spindle taper (with optional BT 40 compatibility) capable of reaching 12,000 RPM and delivering 15 HP for 30-minute operations. The work table measures 32.3 inches long by 16.1 inches wide, accommodating workpieces up to 660 pounds. The three-axis machine provides 24 inches of X-travel, 16.1 inches of Y-travel, and 20.1 inches of Z-travel, with rapid traverse rates of 2,362 inches per minute across all linear axes. An optional fourth rotary B-axis enables 360-degree positioning for complex part geometries. The automatic tool changer (ATC) holds 30 tools with exceptional efficiency—tool changes complete in just 1.3 seconds, or 4 seconds with chip clearing. A standard two-pallet changer allows continuous production workflows by enabling part loading and unloading while machining proceeds on the active pallet. Maximum feed rates across all axes reach 1,181 inches per minute, supporting aggressive cutting strategies. The spindle's 12,000 RPM capability suits precision machining of various materials, from metals to composites, achieving positional accuracy of 0.01 mm across the work envelope. This configuration balances versatility and productivity, making it suitable for production runs requiring rapid tool changes and consistent dimensional accuracy across medium-to-large workpieces.
