New spindle, new Z axis, new towers, New Machine!

April 26, 2011

It’s been some time since I have updated on my CNC machine, and quite  a few changes to my machine have taken place.

 

The new Spindle and VFD was ordered from China. Its a 3KW air-cooled spindle with a matching 3 phase VFD. It will do any speed between 0 and 24,000 RPM.

Google G1 in there for scale...

 

Here she is mounted to the machine. The tapped bolt holes make for a quick and easy mount job. At first I had the unit plugged in backwards so as I was actually spinning the end mill backwards. That meant that it was simply burning through the material. Ha! After I flipped two of the three phase wires, she ran the right way and cut like a dream.

Note the updates. New Z axis, and fully alum towers.

 

Currently I am working on controlling the speed of the unit by communicating via RS485. I have a USB to RS485 converted, but the VFD appears to be not communicating properly.

 

In the meantime I have been working on a few secondary systems. I cut the probe mount on the unit itself out of HDPE. The homing switches have also been installed.

Cut on the machine out of HDPE (chopping board) Currently has a few 'noise' issues. Hope to fix it with shielded wiring.
