Standard Operating Procedures

General

  1. Do not wear gloves.

  2. Never wear loose clothing or jewelry.

  3. Avoid reaching into a CNC machine while it’s running.

  4. Refrain from placing hands near a revolving spindle.

  5. Under no circumstance shall the machine be left to where someone else is able to start it by pressing the cycle start button.

  6. Always check that the machine is not operating when loading a tool magazine.

  7. Check that the tools are in good condition.

    • e.g. sharp and free of cracks.

  8. Confirm that the correct tool data is entered into the CNC program.

  9. Verify that the seating surfaces are clean before installing tools.

  10. Use only the right tools. Only use tools within the limits specified by the manufacturer.

  11. Do not use the machine table as a workbench.

Startup

TBD

Operation

  1. Make sure to keep the area around the machine clear of obstacles.

  2. Stack the materials where you can reach and that are clear of moving parts of the machine.

  3. Check that tools are sharp and set correctly.

  4. Confirm that all work and fixtures are clamped securely before starting machine.

  5. Always make sure spindle direction is correct for right-hand or left-hand operation.

  6. Conduct a dry run to ensure the program is correct.

Shutdown

  1. Press the MDI mode key and enter the tool number of an empty pocket starting with letter T and number, then press ATC forward or ATC reverse to execute the tool change.

  2. Next use the handle jog mode to bring the machine table to the center in reference to axis X & Y.

  3. Power OFF the machine and open the door to avoid built up of humidity.

    • It is not recommended to blow excess coolant off the vises or machine table; coolant contains an oil which protects the machine’s surfaces from rusting.

Emergency Stop Button

  1. In the event of incorrect operation or dangerous conditions, the machine can be stopped immediately by pressing the E-STOP button.

  2. Pull button back to restart machine.
