I used a 500W china spindle for my tests.
Plexiglas (PMMA)
Melts at 160°C (even earlier than your printer's PLA or PETG).
These are the main challenges:
- Make sure the chips leave the flute so they can't friction weld (dust shoe, compressed air)
- Finding the highest cutting volume (diameter*speed*attack) while keeping the tool as cool as possible
cutter | diameter (mm) | speed (mm/min) | plunge (mm/min) | attack (mm) | rpm | cooling | notes |
---|---|---|---|---|---|---|---|
single-flute | 2.0 | 300 | 30 | 0.5 | 10,000 | none | Great result, more should be doable! |
single-flute | 2.0 | 400 | 30 | 0.75 | 10,000 | none | Looks good, might be the limit before it shows. |
single-flute | 3.175 | 100 | 30 | 0.5 | 10,000 | none | Looks good. 300mm/min also tested, PMMA was melting. |
Engraving
0.5mm deep TBD TBD
Poplar plywood (Pappelsperrholz)
cutter | diameter (mm) | speed (mm/min) | attack (mm) | plunge (mm/min) | rpm | cooling | notes |
---|---|---|---|---|---|---|---|
single-flute | 2.0 | 300 | 30 | 2.0 | 10,000 | none | Great result, more should be doable! |
Pine plywood (Kiefersperrholz)
cutter | diameter (mm) | speed (mm/min) | attack (mm) | plunge (mm/min) | rpm | cooling | notes |
---|---|---|---|---|---|---|---|
single-flute | 2.0 | 400 | 2.0 | 100 | 10,000 | none | Works out fine, more speed should be possible. |
OSB (Grobspanplatten)
cutter | diameter (mm) | speed (mm/min) | attack (mm) | plunge (mm/min) | rpm | cooling | notes |
---|---|---|---|---|---|---|---|
single-flute | 3.175 | 500 | 0.75 | 80 | 10,000 | none | Works out fine, more speed should be possible. |
single-flute | 3.175 | 555 | 1.00 | 127 | 10,000 | none | Works out fine, more speed or attack should be possible. |
single-flute | 3.175 | 555 | 2.00 | 127 | 10,000 | none | Works out fine, more speed or attack should be possible. |
