Cheers Dean, after doing the first cuts yesterday it did sort of click that I was trying to run before I could walk
For others, this is what 'cooked by end mill' MDF looks like
It was just so tempting as I had the material and tools all at hand so thought why not
The tools and details I am using are the following, all cheap eBay 2 flute cutters, aluminium grade either 5083 or 6082 as I could get either:
Cutting Pocket 1mm depth 40mm diameter - 6mm ball nose (50mm total length, Carbide tool, 20mm stick out)
Finishing 3D relief (1mm overall depth) after roughing with the 6mm ball nose - 2mm ball nose (50mm total length. Carbide tool, 14mm stick out)
VCarving text at depth of 0.35mm - 6mm 90 deg Spot Drill (67mm total length, HSS tool, 20mm stick out)
Profile part at 5mm depth - 8mm End Mill (61mm total length, HSS tool TiN Coated, 30mm stick out)
All tools got hot but the final profiling end mill was the one that got REALLY hot. Getting air connected will be easy enough as pipe, parts & 3 nozzles at spindle are setup but think I might have to start work on the mist setup sooner rather than later. Could I get away with air blast with manual spray of WD40 for now with smaller runs? Thanks.Last edited by examorph; 29-01-2017 at 01:55 PM.
