2019 FANUC D21LIA VERTICAL MACHINING CENTERS

Technical Description

The 2019 Fanuc RoboDrill D21LiA (Alpha-D21LiA) 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 27.6" 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 "L" suffix denotes long X-axis travel configuration. The D21 platform uses a BT40 spindle taper for improved rigidity on larger workpieces. This 3-axis version is well suited to high-throughput production of medium-sized precision parts. 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 5,510 lbs reflects its compact but rigidly built construction. The RoboDrill D21LiA (Alpha-D21LiA) is best suited to production environments requiring fast cycle times, high accuracy, and minimal floor space.
