Some Information about End Mills (Rotational Cutters) for CNC Machines
I receive a healthy dose of questions about end mills and which ones that I use. I usually respond with answers like, my end mill will probably differ from your end mill. So, what is this thing called an end mill anyhow? If you are new to CNC machining and routing, you may have never heard of the thing. I could imagine googling something like, "CNC bits". Using the terminology "bit" is not all that incorrect. Bits are commonly referred to as drill bits, but routers use router bits. If you're looking to cut various metals and composites, end mills are the tools of choice. However, end mills will also work on wood, depending on the type of end mill selected.
Sam S. and His Hacked redFrog
When I said you can hack the redFrog, I wasn't kidding, and Sam took this seriously. Almost every customer that has purchased the redFrog has hacked the machine in some way or another. I found this hard to believe until I saw Sam's redFrog with my own eyes.
Demonstration of Spoilboard Surfacing with an Onsrud Surfacing Cutter
The video below is a quick demo of us doing a bottom clearing on our CNC machine using our new Onsrud Spoilboard Surfacing Cutter. It's generally a good idea to resurface the spoilboard when you first set up your CNC machine. This will make sure the spoilboard surface is perfectly parallel with the X/Y motion of your machine. You should also resurface every so often as the spoilboard surface becomes more uneven over time. This is a better alternative to replacing the board every time it becomes worn down.
