This is a common problem long before there were computers controlling the tools. I use 100% alcohol. But you can buy a solvent that is specially made for this from woodworking shops. http://www.rockler.com/rockler-pitch-resin-remover Either way, let the tool soak at LEAST over night. On

What is the best way to clean plywood glues off small carbide router bits? I use small carbide bits to work wood and sometimes plywood. Mostly smaller than 3mm(1/8 in) bits. Sometimes plywood glue melts onto the bits.Cleaning them is a problem. Suggestions? Craig

Like this. Could remove the pot and switches to remote mount or connect to something else for control inputs. One switch is on/off, other is direction. Pot is speed control. http://www.ebay.com/itm/311203030663 On Thursday, April 13, 2017, 11:15:13 AM MDT, Jon Elson

Do test runs in wood or machinable wax or plastic. Could try spraying a dry graphite film on the cutter. NAPA auto parts has spray cans of that. Don't mill the crappy aluminum alloy. On Thursday, April 13, 2017, 8:46:03 AM MDT, Todd Zuercher wrote:Here I go again.

Re: [Emc-users] Milling Aluminum.

The higher chip load is a step in the right direction, but without lube it isn't enough. Bit broke after about 1.5" of cutting, but it's flutes weren't jammed full of welded swarf this time. I switched to the O-flute bit, and that seems to be the ticket. Single flute @14000rpm and 80ipm.

Re: [Emc-users] Milling Aluminum.

Yea I thought your recipe looked pretty good. I think the missing ingredients are lube and chip evacuation. My steps below are my basic guideline for setting up a cutter for aluminum with HSM paths. I have not broke a cutter while using those guidelines and flood coolant since I started using

Re: [Emc-users] Milling Aluminum.

My material is only 1/4" thick, so more tool engagement is not an option. I ran a test with 1/2" circles (1/4" loops for the tool center) and the feed rate increased to 80ipm. I also decreased the step to 0.025". The results were about the same. With the 80ipm @18000 and the 2 flute cutter

Re: [Emc-users] Milling Aluminum.

Lube is your friend. I try not to do any aluminum cutting without lubrication. I think your air blast and lube will get you a long way towards better tool life. What is the overall thickness you are cutting? If it is more than 1/4" I would recommend using the full cutting length of the cutter

I may yet do that, but then I'd have to learn how to use it... and technically this doesn't fall under their "free use" terms. Is what I did really all that different from a "real" trochoidal path? https://pastebin.com/nbQ1AKia. - Original Message - From: "andy pugh"
