Air instead of coolant

[FLIPPER™]

Hello everyone,

Recently we adapted some older vertical milling centers with air to cool some carbide cutting we are doing. Converted the post to accommodate the mist option to generate the “G” code on and off. Everything is good. Because these are older machines and not fully enclosed, they are very loud and is now causing a problem. Are there any types of nozzle ends or other options that can quiet things down for us. Thank you in advance and will wait for your reply.

The "Coilhose Typhoon" air nozzles move a very large volume of air, not quiet but maybe you can turn the pressure down on these nozzles to help. Not real expensive either.

when our owner complained about the noise, I told him it was the sound of money and he showed up the next day with earplugs for everyone

try a smaller diameter nozzle. you get a more concentrated, and stronger flow with way less air pressure. ours are about 1/16" dia......the sound of the chips hitting the window covers the noise from the nozzles.

McMaster Carr part number 31875K12. Found on page 2472 item 'D' under air nozzles. These things work great and at $33.63 each, they wont break the bank. Quiet, quiet, quiet, and they move a lot of air too!!!

Thanks to all of you
