Bridgeport CNC Mill

Bridgeport CNC Mill

Starting point for information related to the Bridgeport Torq-Cut 22 CNC milling machine. Very much a work in progress.

Start-up procedure

• Power up CNC mill with power switch on back panel. Clockwise is "on", counterclockwise is "off".
  

Power Switch - from rear of CNC mill

Main power switch in the "on" position.

Power Switch - "on" position.

• Start (and stop) air compressor
  

The CNC mill requires compressed air so the shop air compressor has to be running.
If no one else needs compressed air, don't forget to turn off the compressor after you're done. There's a leak somewhere in the system.

• Valve to shop compressed air at CNC mill.

• Lift red air valve on CNC

You'll find the machine's air valve on the left side of the mill. Just raise it.

Next thing you want to do before you start using the mill is check that its fluid levels are where they're supposed to be. The first thing to check is the lubricant level.

There's a level marked on the duct tape.

The lubricant reservoir.

If the lubricant level's where it's supposed to be then check the coolant level.

Location of the coolant reservoir.

There are filter screens on both sides of the coolant tank that can be removed to check coolant level.
The screens have handles but they tend to be pretty grimy so be warned.

To recap, power on, air on - shop compressor on if it's off - raise air valve, check lubricant level, check coolant level.
