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.
