Okay I looked up the specs, looks like closer to 1600lbs (7.1kN) so it should be totally fine!

If I were to do a belt drive reduction... Let's say 4:1 with now a 750w servo - am I going to be driving the 16mm lead, 16mm diameter ballscrew too hard? Accelerating 200lbs at roughly 2g? Ballscrew...

If I were to stick with 400w servos, 16mm pitch.... what kind of cutting would I be limited to? Would I be able to use a .375" 3 flute end mill in aluminum, .375" deep, .050 stepover, 15k rpm, 200...

Okay yes this is exactly what I had in mind, we are on the same page. I'm actually a Galil distributor, so maybe I'll take a look. It's just hard to look at a $1000 controller when my...

One thing I'd be concerned with in this case is the servo control. The encoder is used for real time velocity calculations by the servo drive. For example a Yaskawa servo encoder has roughly...

Hi guys

Been a lurker for a long time. Made my first CNC router/mill about 11 years ago when I was in college, but have never been super thrilled about the performance.... Recently I picked up a...

Magno,

I think it's silly for you to post a thread asking for opinions and then not take them seriously. Like several people have mentioned, calculations of cutting force will not always give you...

Thanks for the awesome responses. I showed the part to the guy who drew it up and he said wow those channels are too small! -.- so I re-made the part with a 1.6mm endmill , lowered the feedrate to 4...

Just using compressed air. What would you recommend I knock it down to?

My machine is rigid enough to do light steel machining, no issues with aluminum, even with larger endmills. A 1mm endmill should provide no issues with respect to rigidity..

Hi Guys;

I'm currently making a part for someone that has 1mm wide .1" deep channels milled into aluminum. I have a homemade CNC machine including the spindle.

I ran a few tests before setting...
