Thank you! Shiny edges are very important

Yes, brushless servos all round again, I'm very pleased with them. I was also struck by how quiet they are, despite being tuned very 'stiff'.

Best regards,

Here's another machine running Granite Devices drives, this time VSD-E 160Vdc model. Also using the new SPS-600-126 power supply as well, with 225 watt brushless servos.

Still some work to do commissioning this machine, but so far I like it very much!

Ps - wonder why the video isn't embedded this time?

The fan grill on that part is pretty cool. Nice video.

Very Nice drives... What are the prices?.. Amazed to see the 3D carving at that speed.

Hi Khalid,

The VSD-E is €199 (about US$255), VSD-XE is €243 (about US$312).

Best regards,

Hello Jason,

I watched your video and was surprised to see that you are cutting the aluminum dry. What type of bit were you using? I have trouble with the aluminum building up on the bit unless I use some type of lubricant. WD40 works well for me but tends to make a mess. Would you mind sharing your secrets.

Very nice machine.

Hi Larry,

I was cutting dry, yes. It was more a matter of getting away with it by using a very light cut than anything else. It was a conservative start for the machine, I wanted the part to work first time but really feel this mill could do a lot better. It was a 1/4" 3 flute, high helix cutter, feed rate was 80 ipm and rpm was 20,000. That will probably wear the tool prematurely. The part was a bit warm afterward, so the chip load was too small - tool tables tell me I should have the feed rate at 385 ipm and 32,000 rpm. I'll give that a try and see how it goes, my guess is the tool will clog and break without coolant.

Regards,

Jason

Oh, and Gerry - thank you for the kind words. I'm still using your Mach3 screen and really liking it. Thanks again for sharing it after all the work you put into it!

Regards,

Jason

Great videos as usual, Jason! Keep up the good work.

Here is another kind of VSD-E and AC servo application:

The drive is installed in enclosure as intended (connectors reaching out of box, shown at end of video).

That's great, I like it. What is it?

looks like there's a photodiode on the end of the moving arm, and it's measuring how much optical power a light-source, such as an LED, is outputting in each direction.
