Machine Comparison
Fanuc Robodrill α-D21MiB5 vs Fanuc Roboshot Alpha-S100iA
Fanuc vs Fanuc · Vertical Machining Centers
Summary
The Fanuc Robodrill α-D21MiB5 and the Fanuc Roboshot Alpha-S100iA share a maker and a control family, but they are different kinds of machine and serve different jobs. The Fanuc Robodrill α-D21MiB5 is a compact machining center used for drilling, tapping and small 5-axis parts. The Fanuc Roboshot Alpha-S100iA is listed for molding work: its typical buyers run molds and look for clamping force and fast cycles, not a cutting spindle.
The makers publish few comparable figures for this pair, and the table holds only the control and the machine weight. The Fanuc Robodrill α-D21MiB5 runs the Fanuc 31i-B5; the Fanuc Roboshot Alpha-S100iA runs the Fanuc 31i-B with the Roboshot HMI. No row names a winner.
Specifications Comparison
| Specification | Fanuc Robodrill α-D21MiB5 | Fanuc Roboshot Alpha-S100iA |
|---|---|---|
| Control | Fanuc 31i-B5 | Fanuc 31i-B with Roboshot HMI |
| Machine Weight | ~3,900 kg (8,598 lb) | 4,500 kg (9,921 lb) |
Advantages
Fanuc Robodrill α-D21MiB5
- A machining center: drills, taps and mills metal parts, including multi-face work in one clamping
- Fanuc 31i-B5 control, with a 5-axis option listed for small parts
Fanuc Roboshot Alpha-S100iA
- A molding machine: suited to plants producing molded parts in fast cycles
- Fanuc 31i-B control with the dedicated Roboshot HMI
- Listed as a replacement for hydraulic machines where energy use matters
Verdict
This is not an either-or choice. A shop that needs to drill, tap and mill small metal parts wants the Fanuc Robodrill α-D21MiB5; a plant that needs to mold parts wants the Fanuc Roboshot Alpha-S100iA. The only practical overlap is the control family, Fanuc 31i-B5 against Fanuc 31i-B with the Roboshot HMI, which may matter to a plant that maintains both types of machine. Nothing else in the table supports a comparison.
