Yes it is compressed air. And it also sprays a little bit of oil over the work piece and on the mill. You don't really see it but i love it.
The work piece keeps cool and the mill lubricated. The video is about 12x faster than original. I am gone update the mill motor for higher rpm.
So i also can increase milling speeds. i really need that enclosure then i can go full speed!! And if any one needs something milled don't hesitate to ask!

second test video, this time with mist coolant.
Update on the cnc mill: Did some painting last week, now putting things to gather.

today finished the oil groves for X and Y axis. Also made a start on the cable rubs.

the blue dyken fluid comes from ebay uk, it works so great. Wish we bought it earlier. Use that in combination with a granite block and a height meter.

On the cnc machine, last weekend did a first full test run on a small piece of alu.
Right now the hole machine is taking apart, to add a lubrication system.
the used motors for the X and Y axis are nema 24 3nm closed loop motors.
On the Z axis there is a nema 34 8nm closed loop stepper.
All driven by a usbcnc v5b quite expensive but is have a very nice user interface and we use this software also for the current cnc mill.
right now waiting on the enclosure to be made, and then the whole machine can be put back together for the last time.

Status update on the bf25 mill, Y and Z axis have already moved with the computer. Now working on the X axis.
This weekend we started working on our new Featherweight, Equinox. It will be a four wheel driven robot with a drum on its front. Its a bit inspired by Rango/Django.
Like Omega it will have a fully shockmounted brushless drive system. Omega is way overpowered so we chose the slightly smaller NTM4258-500KV this time.
The gearbox consists of two stages, a 3:1 with bevel gears and a 3:1 stage with a T5 belt.
The aluminium frame that you see on the last two pictures is purely as a mock-up/prototype.

the brushless drive had plenty of power it pushed 2 or 3 robots a way without a problem.
On our fb page you kan see al the fights

The part on the last phote is the motor for the Z axis including the bearing holder block. on this photo you can see the complete machine so far.

The build tread is not really complete due the shutdown of the forum.
Omega did a really great job on the robochallange 2016, we knocked out in the quarter final witch means we where there by the last 8 robots out of 40.
We didn't have any damage on the shell, there are still some things to tweak on the drive train especially on the bearing that keep the axis in place.
This machine has enormous pushing power, i think that on the DRG and GRA arena floor it even wil have more grip.
right now we are working on converting our old bf25 mill to cnc. some pictures of the build so far:
keep you posted.

the new generation of battlebots are really cnc porn!
Time for an update, we made a first test drive and it drives great!
frame have been welded. also made a fuse holder for a 200amp fuse.

today started on welding the frame:

Me and Dennis will be the there on the first Saturday morning session in de audience. I am really curious about the show!

Today finished installing my new milling machine. It have a 3 phase motor with vfd drive. We also added a dro on it witch makes milling a lot easier.
stef
one side almost done.

Made some small progress today:

@ bat_boy do you mean otis? it drives really great with brushless motors.
@ ibf
we use this rubber on otis and ODF to. It has very good grip on wood and you can make your wheels in every size you want.
