What this machine will and will not work
| Wood Production | This is the machine's production material and the reason it is 3 000 x 1 500 mm. Ply, MDF, particle board, pine, teak, rubberwood and hardwood all cut cleanly. The reference cut is a 12 mm two-flute compression cutter taking a full-width through-slot in 18 mm birch ply at 6 000 mm/min - 1 296 000 mm3/min at about 1 296 W, roughly 59 % of installed spindle power and about a third of the machine's force budget. Nested cabinet parts, door frames, signage blanks and jigs are what this machine does all day. Run the shoe and the extractor: at this rate the dust, not the cut, is the limiting factor. |
|---|---|
| Plastic Production | HDPE, Delrin, nylon, ABS and PVC foam board machine very well with a single-flute O-flute at 14 000-18 000 rpm and a deliberately high chip load - the rule on plastic is chip load, not speed, because too fine a chip melts the material and welds it behind the cutter. Run the air blast. Do not cut PVC sheet: milling it is fine mechanically, but the dust and any local heating release hydrogen chloride, and this machine is an open frame with dust extraction, not fume extraction. |
| Acrylic Capable | Cast acrylic profiles and engraves cleanly with a single-flute O-flute at 14 000-18 000 rpm at a coarse 0.10 mm chip load, finishing with a climb pass. Extruded acrylic melts behind the cutter unless the feed stays high. Class is 'capable' rather than 'production' because a polished edge takes tuning per sheet and per supplier, and because large acrylic sheets need more clamping than ply - acrylic that lifts mid-cut cracks rather than tearing. Air blast only, never a liquid coolant, which crazes it. |
| Aluminium Light duty | Light cuts only, and the whole machine is sized by exactly this cut: 6061 and 6082 with an 8 mm three-flute carbide at 15 000 rpm, 2 mm radial by 8 mm axial, 0.05 mm per tooth, 2 250 mm/min, air blast, adaptive or trochoidal toolpaths. That is 360 N and it is the entire force budget. Here is the part that decides what the parts look like: at 2 647 N/mm of static stiffness, 360 N is about **0.14 mm of tool-tip deflection**. The cutter takes what is left after the machine has bent, and gives it back on the next pass. Treat the sizing cut as roughing, leave 0.3 mm on the wall, finish at half the radial engagement and follow with a spring pass. Roughed only, expect about +/- 0.2 mm on a wall; with the finishing and spring pass, about +/- 0.1 mm. Expect brackets, gussets, sign faces, jig plates and composite panel work in 3-10 mm stock. Do not expect to hog a slot, and do not expect a 0.05 mm tolerance from any 3 m gantry in this price band. |
| Steel Not supported | Not supported, and no setting changes that. Steel at a 0.03 mm chip needs roughly 2 000 N/mm2 of specific cutting force - more than twice the aluminium figure this machine was sized against - and it needs a spindle with real torque at 1 500-3 000 rpm, which a 2.2 kW spindle with an 8 000 rpm floor does not have. On a 2 647 N/mm structure the attempt deflects the gantry, rubs instead of cutting, work-hardens the surface and destroys the cutter. Steel milling on a Roboda platform starts at RBK-E1. |
| Mild steel Not supported | Not supported for milling, for the same reasons as steel plus one more: hot-rolled mild steel carries an abrasive mill scale that a carbide cutter can only get under by taking a deep first pass, and a deep first pass is exactly what a 360 N machine cannot take. Note that mild steel sheet *cutting* is available on this platform - but only on the plasma variant, where the tool is an arc and not an end mill. The spindle kit does not cut mild steel. |
