BRIDGEPORT DO’S AND DON’TS

DO

  • Ensure you have received training before performing an operation on this machine
  • Use appropriate coolants and lubricants designed for machining
  • Remove all tooling and extra fixtures used for your operations
  • Check the collet and inside of spindle for loose chips to prevent damage to both
  • Oil the ways to keep things moving smoothly and protect from corrosion
  • Report any damage or broken tools right away so they can be fixed/replaced

DON’T

  • Use water as a coolant without putting a rust-preventative in it like Kwikool
  • Leave metal chips on the machine or on the floor
  • Adjust or remove the vise, rotate the head, or modify the machine if you don’t know how the process to “tram” them back to square
  • Forget to clean up and put tools back in their proper place
  • Use endmills in the drill chuck

General Tips and Safety

  • Wear safety glasses! Chips that come off are hot, and if your whole part comes off it will not be pretty.
  • If you need a sharp endmill, you should have your own set. Our tools are shared use and are not always the sharpest.
  • Clean and oil the machine's ways and surfaces when you are done
  • DO NOT USED COMPRESSED AIR TO CLEAN
  • DO NOT USE WATER AS A COOLANT. Water will rust the precision metal surfaces, making them not precision anymore. Use a rust-preventing additive like Kool Mist.
