Dual drive Gantry, how fast are your speeds?

[Boyan Silyavski]

5000mm/s is perfectly ok for normal work.

First of all use your spindle to the max RPM and better download HSM adviser so you figure better what speeds and feeds combinations will give you better Material Removal Rate, which is what matters, not how fast your machine moves.

Ok - but the RPM the calculators are asking for are actually more like 6000 rpm, if I'm cutting at say 3000 mm/min. If I wanted to use the router at 100% ( 24,000 rpm ), then it would ask me to go faster than my rapid speeds - 12,000 mm/min

enter carbide tool, if you enter HSS that could happen. And you can limit the rapid speed programming your machine. DId you down load HSMAdviser trial?

here bellow 3 simulations 12mm indexing 1 flute bit / this is absolutely tremendous cutter/ , 6mm and 3mm .

these are real speeds for wood, as i use them without problem. just adjusted to your machine. On mine i cut ~16000 mm/min on some occasions at 3000mms2, but my point is that such speeds are not everyday needed. only special bits go at that speed.

Yes, cutting speeds maybe not needed to be that high, but my work pieces are huge, so having a quick rapid can reduce machining time for things like parallel climbing finishes, by hours, also, the finishing cuts where only 1/2 MIL of say wood is removed, I don't need to be doing 3000 mm/min, I should be going faster?
