I’ve just started running flood coolant and my ATC together and have begun experiencing pull out on some of my tools. I’ve followed Tormach’s guidelines on preventing collet slip and am fairly certain that the reason for the pullout was a TTS shank wet with coolant. After the pullout occurred, I checked all of my tools in the ATC and all were coated with coolant and fairly slippery.

Has anyone else with an ATC experienced similar issues when using flood coolant? I’m thinking about building some type of splashguard for the ATC itself, and would love to hear if anyone else has done that/ found a simpler solution.

The cut that caused pullout was a radial 0.075" DOC .4" WOC at 4575 RPM and 90 ipm with a 0.5” 3 flute HSS rougher in 6061, fyi. I’m not a very experienced machinist, but that seems like a pretty wimpy cut to cause collet slip on its own.

Thanks,
FG
