2005 FANUC 21ITB VERTICAL MACHINING CENTERS

Technical Description

The 2005 Fanuc RoboDrill 21ITB (Alpha-T21iT) is a 3-axis compact drilling, tapping, and milling center designed for high-speed, high-precision machining of small-to-medium precision parts. The RoboDrill series is manufactured by Fanuc Corporation and is widely used in automotive, electronics, medical device, and precision component manufacturing due to its combination of speed, accuracy, and compact footprint. The machine features a BT30 spindle taper and reaches a maximum spindle speed of 10,000 RPM, enabling aggressive high-speed cutting strategies in aluminum, brass, and plastics, as well as precision steel and titanium work at reduced feeds and speeds. Continuous spindle power is approximately 7 HP. Axis travels are 19.7" in X, 15.7" in Y, and 13" in Z. The 21" worktable provides a compact but sufficient fixturing surface for the parts sizes targeted by this platform. All axes use linear roller guides and high-speed ball screws for minimal lost motion and excellent surface finish quality. The "B" designation within the T-series indicates a mid-cycle refresh with updated servo drives and control software for improved positioning stability. Control is provided by the Fanuc Series 16i, which delivers fast block processing speeds suitable for high-speed contouring, with support for rigid tapping, nano-smoothing, and AI contour control where equipped. The RoboDrill's tool changer typically holds 21 tools (or 14 in compact configurations), with chip-to-chip times under 1.4 seconds for maximum throughput. The machine's approximate weight of 4,400 lbs reflects its compact but rigidly built construction. The RoboDrill 21ITB (Alpha-T21iT) is best suited to production environments requiring fast cycle times, high accuracy, and minimal floor space.
