What this machine will and will not work
| Wood Production | This is the material the machine was sized on. The design cut is a 3.175 mm two-flute carbide in seasoned hardwood, full-width slot, 2.0 mm deep at 0.04 mm per tooth, 10 000 rpm, 800 mm/min - 5 080 mm3/min at 5.9 W. Softwood, plywood and MDF run the same tooling faster: 3 mm depth and 1 200 mm/min are comfortable. Depth of cut, not feed, is what this machine runs out of, so take more passes rather than one deep one. Extract the dust; the machine does not. |
|---|---|
| Plastic Production | Delrin, HDPE, nylon, ABS and PP machine well with a single-flute 3.175 mm cutter at 8 000 to 10 000 rpm and 600 to 1 000 mm/min, dry, taking 1.5 to 2 mm per pass. Single-flute matters: a two-flute cutter at these speeds re-cuts its own chips and welds them behind the tool. Never cut PVC or PTFE on any machine, this one included - the decomposition products are corrosive and toxic. |
| Acrylic Capable | Cast acrylic cuts and engraves cleanly with a single-flute O-flute at about 10 000 rpm and 700 mm/min, 1.5 mm per pass, up to about 6 mm thick in multiple passes. Extruded acrylic melts and re-welds behind the cutter unless the feed is kept high, and the 70 W spindle sags before it can hold the speed for a heavy pass. Class is capable rather than production because acrylic wants either more spindle power or more feed than this machine has in reserve, and because a chipped acrylic edge is unrecoverable. |
| Aluminium Light duty | Possible, slow, and only within tight limits. 6061 or 6082 sheet up to 3 mm, 1 or 2 mm single-flute carbide, 0.2 mm depth per pass, about 150 mm/min, 10 000 rpm, with a drop of paraffin or cutting fluid and the chips cleared every pass. A 40 mm bracket takes about twenty minutes. Anything deeper pushes the wheel-way past its comfortable range and chatters, and chatter in aluminium welds chips to the flutes and ends the cutter. Do not attempt cast or 7000-series alloy, and do not attempt pockets deeper than the sheet thickness. |
| Steel Not supported | Not supported, and no technique makes it possible. Static stiffness at the tool tip is 449 N/mm; milling steel needs roughly two orders more. The spindle turns 70 W and will not go below 3 000 rpm, where steel needs high torque at a few hundred rpm. There is no coolant, no flood guarding and no way to clear hot chips. An attempt snaps the cutter within seconds, flat-spots the acetal wheels and can permanently bend the Z column. Steel milling on a Roboda kit starts at the enclosed C-frame platform, not here. |
| Mild steel Not supported | Mild steel is not supported on this platform for exactly the reasons above, and hot-rolled MS adds one more: the abrasive scale on the surface destroys a small carbide cutter before it has removed any metal at all. Nothing in the assembly, the tooling or the settings changes this - it is a stiffness and spindle-torque limit, not a configuration one. Marking or engraving MS is also outside this kit: even a scribe pass loads the Z column past its design budget. |
