I only plan on cutting wood and maybe some plastics.
I have already read that thread from start to finish which is why my original plan was to make one of those brushless spindles, thats why i made my motor mounts to suit 52mm dia spindle body. However making a spindle now is out of the question as I no longer have access to a workshop. I really do miss the working on the tools sometimes!
26-07-2016 #12are the air cooled ones really much worse than the water cooled? because i'm under the impression that the water cooled system requires a separate water tank and pump? which would just put the price up further.
and a 2 ltr Tupperware container for the water...Clive
How much would you be willing to sell it for Neil? Because something like that would be perfect for my machine and I still have the option upgrade to a water cooled spindle later on when I have more money.
What are the sizes/specs?
Thanks Neil I'll have a look through the thread then and let you know.
Is 6500rpm fast enough though? I thought much faster spindle speeds were needed for wood carving?
Thanks for the offer Neil but i think i'm going to go with the water cooled spindle. I think the 0.8kw spindle would be fine for my machine but as the 1.5kw is only about £5 more through the same supplier on ebay i might just go for that one.
Thanks again for everyones help, i will more than likely be posting soon with questions on how to wire it up lol.
But if you just want manual speed control then you can also get a much simpler and cheaper one, like this:
On the other hand... I have a similar spindle and have speed control as well, but I almost always run the motor at full speed. The motor is pretty weak and by reducing the speed it gets even weaker. So, it depends what you want to do with your CNC, perhaps speed control is not necessary at all.
Many people say that brushless air cooled spindles are noisy, and maybe they are noisier than water cooled ones, but definitely not noisier at the same speed as the DC motors, or brushed motors like the Kress. Air cooled motors are easier to handle as well, since you don't need to install water pipes, cooling fluid, pump and pump control. Never the less, of course, if you are going to use your CNC 8-10 hours a day 5-6 days a week then water cooled is worth the trouble, but again, even if you buy air cooled to start with, upgrading to water cooled once you realize you need it is pretty simple.
01-08-2016 #20even if you buy air cooled to start with, upgrading to water cooled once you realize you need it is pretty simple.
For the water cooled you will need a small pump £3 from eBay and a 2lr Tupperware container for the water. No contest.
Be aware that both of the above only have ER11 collets
