2021 FANUC D21M VERTICAL MACHINING CENTER

Technical Description

The 2021 Fanuc RoboDrill D21M (Alpha-D21M) 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 BT40 spindle taper and reaches a maximum spindle speed of 24,000 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 10 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 "M" suffix denotes a mid-travel X-axis configuration. The D21M uses a BT40 spindle taper and is designed for high-speed precision milling of medium-size components where a full long-travel X-axis is not required. Control is provided by the Fanuc Series 31i-B5, 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 5,070 lbs reflects its compact but rigidly built construction. The RoboDrill D21M (Alpha-D21M) is best suited to production environments requiring fast cycle times, high accuracy, and minimal floor space.
