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 6 mm plywood, full-width slot, 1.0 mm deep at 0.025 mm per tooth, 15 000 rpm, 750 mm/min - 2 381 mm3/min at 2.4 W. Softwood and MDF run the same tooling at the same depth or a little more; seasoned hardwood wants 0.6 mm a pass rather than 1.0 and a slower feed. Depth of cut, not feed, is what this machine runs out of, so take more passes rather than one deep one - and take them at the same depth even if you fit a 550 W trim router, because the limit is the frame at 203 N/mm and not the motor. 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 12 000 to 20 000 rpm and 600 to 900 mm/min, dry, taking 1.0 to 1.5 mm per pass. Single-flute matters at rotary-tool speeds: a two-flute cutter 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 12 000 rpm and 700 mm/min, 1.0 mm per pass, up to about 5 mm thick in multiple passes. Two honest caveats specific to this platform. Extruded acrylic melts and re-welds behind the cutter unless the feed is kept high, and 900 mm/min is this machine's ceiling, so extruded sheet is harder here than on a faster machine. And a rotary tool that will not drop below about 10 000 rpm cannot be slowed to help - if your tool has a speed dial that reaches 8 000, use it. Class is capable rather than production because a chipped or melted acrylic edge is unrecoverable and this machine has less feed in reserve than the job wants. |
| Aluminium Not supported | Not supported, and stated as such rather than as 'light' or 'possible with care', because this is a first machine and the person reading this is the person most likely to be told otherwise by someone selling one. Static stiffness at the tool is 203 N/mm - less than half the platform above, which itself classes aluminium as a patience exercise - repeatability is 0.10 mm, there is no coolant and no chip clearing, and a rotary tool cannot hold a low speed under load. Being specific, because you would find out anyway: a 1 mm single-flute at 0.1 mm depth of cut and about 100 mm/min with a drop of cutting fluid will remove 6061. What happens next is that the wheel-way flexes, the cut chatters, chatter welds chips to the flutes, and the cutter snaps - into the work, and occasionally into the room. A 40 mm bracket is an hour and three cutters. It is outside the design envelope, it is not covered by warranty, and no spindle option in the catalogue changes it, because the limit is the frame and not the head. |
| Steel Not supported | Not supported, and no technique, feed rate, option or upgrade makes it possible. Milling steel needs roughly two orders more stiffness than 203 N/mm and a spindle that holds torque at a few hundred rpm; a rotary tool's minimum is about 10 000. There is no coolant, no flood guarding and no way to clear hot chips. An attempt snaps the cutter within seconds, flat-spots the polymer wheels and can permanently bend the Z column. Steel milling on a Roboda kit starts at the enclosed C-frame platform, not here and not on the platform above 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. Marking or engraving MS is also outside this kit - even a scribe pass loads the Z column and the 18 mm MDF bed past their design budgets, and the bed will emboss before the steel does. This is a stiffness and spindle-torque limit, not a configuration one. |
