Greetings all! this is my first post!
I wanted to inquire about how to get the fastest cutting speeds out of a Shapeoko 3 XXL. I have NOT bought one yet, but I will be buying one in a month or so, and want to figure out the right upgrades to improve speed and accuracy.
I would be upgrading the belts, spindle, And get the upgraded Z-axis.
As far as cutting speed goes, How can I get the fastest cutting speed possible and what is a reasonable cutting speed and depth of cut for baltic birch plywood? I would plan on making all my prototype speaker horns out of baltic birch, and then move to walnut or other nice hardwoods. but for rapid prototyping, what are some ways to improve the speed. I want to build my machine to mean business.
I will be getting a 2.2kw water cooled spindle, and housing everything in a homemade enclosure with some soundproofing and a dust collection system. I have 3 questions.
What kind of bits should I get, more flutes are better right?
If I run my spindle at a higher speed and have more flutes, wont I be able to cut faster?
how can I make sure my bits don’t get too hot? I assume if i get more flutes and increase the speed and feed rate, the bit will be able to cut, but will get very hot. could I add a dab of thermal paste to the part of the bit that touches he collet, so it can dissipate heat better?
Are there any water cooled spindles you guys would recommend? there seems to be a lot of cheap Chinese ones out there and I dont know what to buy.
