What this machine will and will not work
| Wood Production | The material this machine was sized for. Softwood, hardwood, ply and MDF, cut with the 6 mm two-flute at 12 000 rpm, 4 mm depth per pass and 1 800 mm/min - the design cut, 43 200 mm3/min. Full sheets of 600 x 400 mm fit the bed with clamping margin. MDF is abrasive and halves cutter life, and its dust is the reason the extraction requirement in the safety section is not optional. |
|---|---|
| Plastic Production | HDPE, nylon, Delrin and ABS cut cleanly with a single-flute O cutter at 12 000 rpm and a high chip load - the aim is a chip that carries heat away rather than dust that melts back into the slot. Polycarbonate machines well but grabs, so climb-cut it lightly. PVC and PTFE are forbidden outright: both release hazardous fume when cut. |
| Acrylic Capable | Cast acrylic cuts and engraves beautifully with a single-flute O at 12 000 rpm, 1 200 mm/min and 2 mm per pass. It is 'capable' rather than 'production' for one reason: acrylic wants a fast feed to keep the chip moving, and this machine's honest cutting feed limit is 2 500 mm/min. Extruded acrylic melts and welds behind the cutter more readily than cast; expect to run air blast, and expect scrap while you find the feed. |
| Aluminium Light duty | Light passes only, which is why this is classed light and not capable: a class that means 'will make a bracket in an evening, will not make a batch' should say so in the class and not only in the note. The limits are specific: 6061 or 6082, single-flute 3.175 mm carbide, 0.3 mm depth of cut, 0.4 mm stepover, 400 mm/min at 12 000 rpm, with air blast or a drop of paraffin. That removes about 50 mm3/min. The limit is rigidity, not power: at 426 N/mm the machine deflects into chatter long before the 400 W spindle runs out of torque, and 0.3 mm of engagement is roughly where the deflection stops feeding back into the cut. Do not attempt slotting at full cutter width, do not use flood coolant on an aluminium-extrusion machine, and expect to replace cutters. |
| Steel Not supported | Not supported, and it will not be made to work. Steel needs roughly thirty times the cutting force this machine is designed for, and it needs it at 800-2 000 rpm where this spindle has neither torque nor cooling - its minimum usable speed is 3 000 rpm. A 426 N/mm structure attempting a steel cut chatters, work-hardens the surface and destroys the cutter within seconds. Steel milling begins on the enclosed C-frame and boxed-column platforms in this range, which are built around a 1 000 N budget, not a 60 N one. |
| Mild steel Not supported | Mild steel is not supported for the same reasons as steel, and one more: it is gummy. Cutting it needs flood or mist coolant to stop the chip welding to the flute, and this machine has an aluminium frame, an MDF spoilboard and open bearings - a machine that must never get wet. The only operations this platform will do on mild steel are marking or engraving, and those belong to the laser and plasma variants of other platforms, not to this spindle. |
