What this machine will and will not work
| Wood Production | A production material for both heads, and the pairing is genuinely useful rather than merely additive. The spindle does the work that needs depth and force - 18 mm ply nested and profiled at 3 000 mm/min with a 10 mm compression cutter, rebates, pockets, joinery, 1 200 mm panels. The laser does the work that needs a 0.05 mm kerf and no tool pressure - inlay pockets and their matching inlays cut from the same file, 3 mm ply at about 1 200 mm/min, raster engraving at 4 000 mm/min - the platform's ballscrew ceiling, not the tube's - marquetry, and detail no 3 mm cutter can reach. On one machine with one work coordinate system that is a real capability; the machined 150 mm head offset is proved at commissioning so a laser detail and a milled pocket land on each other. |
|---|---|
| Plastic Production | Production, but by different routes for different plastics, and the rule is to know which head owns which material. **The spindle** mills Delrin, nylon, HDPE, ABS, polypropylene and foam PVC board at 12 000-18 000 rpm with a single-flute O-flute and a deliberately high chip load. **The laser** cuts Delrin, HDPE, polypropylene, rubber sheet and natural leather with no tool pressure at all. The exclusions are absolute and they differ by head, which is exactly the trap this variant creates. **PVC may be milled and must never be lasered**: the cutter is fine mechanically, but a laser releases hydrogen chloride that harms the operator and corrodes the rails, screws and mirrors. **PTFE** must be neither. **Polycarbonate mills beautifully and lasers not at all** - it absorbs 10.6 microns so completely that it chars and burns, which is the same physics that makes it the correct enclosure glazing. **ABS** mills well and lasers badly, giving off hydrogen cyanide. The forbidden-materials placard on the lid lists the laser exclusions specifically, because on a dual-head machine 'the machine can cut this' is an ambiguous sentence. |
| Acrylic Production | Production on both heads and the strongest argument for this variant. **The laser** gives a flame-polished edge straight off the machine in cast sheet of any colour including clear - 3 mm at about 1 500 mm/min, 10 mm at about 250 mm/min - which no cutter can produce at any speed. **The spindle** does what the laser cannot: pockets, rebates, counterbores, engraving into the face, and edge profiling in 20 mm stock. A sign shop's normal job is both: laser the outline and the through-detail, mill the pockets and the mounting bosses, one setup, one datum. Two rules. Acrylic crazes if it meets coolant, so spindle work is on air blast only and never on mist or MQL. And acrylic burns readily under the beam and gives off methyl methacrylate vapour, so extraction and air assist are running and somebody is in the room. |
| Aluminium Capable | **Spindle only, and exactly the S variant's capability with none of it lost.** The spindle axis sits on the Z rail centre-line on this variant, so the 350 N force budget, the 2 059 N/mm static stiffness and every block reaction derived for the spindle kit apply here unchanged - it is the laser that carries the 150 mm offset, precisely because the laser applies no force. 6061 and 6082 with an 8 mm three-flute carbide at 14 000 rpm, 2 mm radial by 8 mm axial, 0.05 mm per tooth, 2 100 mm/min, air blast, adaptive paths. At 340 N that is 0.165 mm of tool-tip deflection, so it is a roughing cut: leave 0.3 mm, finish at half the radial engagement, follow with a spring pass, and expect about +/- 0.08 mm on a wall. **One thing the S kit can have and this one cannot, said here rather than in the small print.** The MQL mist-lubrication option is offered on the spindle kit and **not** on this variant. Oil aerosol migrates, and oil on the ZnSe lens bolted 150 mm away inside the same enclosure absorbs 10.6 microns instead of passing it, heats, and cracks the lens. The published aluminium capability above is an air-blast figure on both variants, so nothing in this table changes - but the upgrade path does, and a buyer whose main job is aluminium should know that before choosing between the two kits. **The laser contributes nothing here.** Bare aluminium reflects over 96 % of a 10.6 micron beam, and pointing it at a polished aluminium surface is dangerous rather than merely useless because the specular reflection leaves the designed beam path. Coating ablation on anodised sheet is a coating effect 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, about 2.4 times the aluminium figure this machine was sized against, plus real torque at 1 500-3 000 rpm that a 24 000 rpm ER16 spindle cannot deliver at the bottom of its range; attempting it deflects the gantry past 0.4 mm, rubs, work-hardens the surface and destroys the cutter. **The laser** cannot: cutting steel with light needs a kilowatt-class source and an assist jet, marking it needs 1 064 nm, and 80 W of 10.6 micron delivers neither. Steel milling on a Roboda platform starts at RBK-E1, steel marking is the fibre head on that same platform, and steel cutting is a plasma head on the large-format platforms. |
| Mild steel Not supported | Not supported by either head, for the reasons above plus one trap each. Hot-rolled mild steel carries an abrasive mill scale that a carbide cutter can only get under with a deep first pass, which is exactly what a 350 N machine cannot take. And that same scale is an oxide that absorbs 10.6 microns far better than the metal beneath it, so it glows convincingly under the beam and looks like marking - it is the scale heating, and it wipes off with a rag. Scribing mild steel with a diamond drag bit in the collet removes no material and is mechanically possible, but that is not milling and it is not published as a capability here. |
