What this machine will and will not work
| Wood Production | A production material on both heads, and the pairing is genuinely useful rather than merely additive. The spindle takes a 12 mm compression cutter through 18 mm ply at 3 200 mm/min for thick panel work, rebates and 3D carving; the laser cuts 6 mm ply in one pass at about 300 mm/min with a 0.25 mm kerf and raster engraves at 4 000 mm/min. The rule of thumb the manual gives: over 8 mm, or anything needing a pocket, is spindle work; under 6 mm, or anything with fine internal detail, is laser work. Both need extraction, and they need different extraction - the 50 mm dust shoe for chips and the 150 mm hood for plume. |
|---|---|
| Plastic Production | Production on both heads with different jobs. The spindle mills Delrin, nylon, HDPE and ABS at 12 000-18 000 rpm with a single-flute O-flute and a coarse chip load; the laser cuts and engraves Delrin, polypropylene, PET, rubber, cork and felt. **PVC and PTFE are forbidden on both heads** - milled they release hydrogen chloride and hydrogen fluoride if the cutter heats them, and cut with a laser they release them at once. **Polycarbonate mills well and must never be laser-cut**: at 10.6 micron it chars, yellows and burns instead of cutting. ABS mills but must not be lasered. The dual head makes knowing which process a plastic belongs to more important, not less. |
| Acrylic Production | This is where the two heads together beat either alone, and it is the strongest reason to buy this variant. The laser cuts **clear, coloured, cast and extruded acrylic** up to about 10 mm with a **flame-polished edge straight off the machine** - a finish no router produces at any feed. The spindle takes the thick stock the laser cannot, mills pockets and profiles, and drills. A typical job runs both: laser-cut the profile and the engraved detail, then mount the part and mill the counterbores. Acrylic burns readily and gives off methyl methacrylate vapour under the beam - extraction on, and stay with the machine. |
| Aluminium Capable | Spindle only, and within the platform's stated ceiling. 6061, 6082 and cast tooling plate with an 8 mm three-flute at 12 000 rpm, 2 mm radial by 6 mm axial, 0.04 mm per tooth, 1 440 mm/min, air blast on, adaptive toolpaths - 216 N of tooth force against a 250 N budget and against the 211 N the 0.597 N.m spindle can hold. At 3 365 N/mm of static stiffness the full budget is 0.074 mm at the tool tip, so treat the sizing cut as roughing, leave 0.3 mm and follow with a finish and a spring pass: about +/- 0.05 mm on a wall. **The laser head contributes nothing here.** 60 W of 10.6 micron is reflected by bare aluminium and raises no melt pool, and a polished aluminium offcut left on the honeycomb is the most dangerous object that can be in this machine, because the reflection leaves the enclosure's designed beam path. Coating ablation on anodised sheet is coating removal and is not published as a metal capability. |
| Steel Not supported | Not supported by either head. The spindle cannot: steel at a 0.03 mm chip needs roughly 2 000 N/mm2 of specific cutting force and real torque at 1 500-3 000 rpm, and this head holds 0.597 N.m and does not run below 6 000 rpm - it rubs, work-hardens the surface and destroys the cutter. The laser cannot: cutting steel with light needs a kilowatt-class source with an oxygen or nitrogen assist jet, and marking it needs a 1 064 nm fibre source that the metal actually absorbs. Steel milling on a Roboda platform starts at RBK-E1 and steel marking is the fibre head on that same machine. |
| Mild steel Not supported | Not supported by either head, for the same torque, speed and wavelength reasons as steel, plus two specific to hot-rolled mild steel. Milling: the abrasive mill scale can only be got under with a deep first pass, which is exactly what a 0.597 N.m spindle cannot make. Lasering: that same scale glows convincingly under the beam and gives the impression that something is happening - it is the scale heating, not the metal marking, and it wipes off. Neither is a published capability of this variant. |
