Bantam Tools Desktop CNC Milling Machine
This SOP outlines the steps for safely setting up, operating, and maintaining the Bantam Tools Desktop CNC Milling Machine to ensure efficient and secure machining processes.
Pre-Operation
Adhere to all software prompts and safety interlock warnings before running any job.
Ensure the operator is wearing eye protaction / safety glasses and ear protection before operating.
Check that the machine bed is clean. Verify the machine enclosure and polycarbonate doors are intact. Ensure the emergency stop button (E-stop) is functional and not engaged.
Install the appropriate end mill by loosening the collet nut, inserting the tool, and tightening securely. Use a 0.25-inch collet if necessary. Ensure the collet is installed correctly and is holding the tool firmly.
Machine Setup
Open the polycarbonate loading door. Secure the material on the machine bed using the T-slot bed or fixturing accessories (depending on the material size and shape).
For precise operations, initiate the manual stock location routine using the Bantam Tools Milling Machine Software.
Ensure the safety interlock is engaged by closing the loading door. This will allow the machine to start.
Software Setup
Download and Launch the Bantam Tools Milling Machine Software.
For 2D/2.5D projects, import SVG files directly into the software. For 3D projects, load a pre-generated G-code file from Fusion 360 or other CAD/CAM software.
Use the software to create or verify tool paths, ensuring they are optimized for the selected material and tool.
Set the tool offset and depth of cut as per the project requirements.
Set the spindle speed to an appropriate RPM (between 10,000 and 28,000 RPM), depending on the material being used (e.g., softer materials like plastics may require lower speeds, while aluminum may need higher speeds).
Operation
Verify all settings, close the door, and start the milling operation through the software. Monitor the machine's progress through the safety window.
If there are issues, press the E-stop button to halt the machine immediately. Resolve any issues, disengage the E-stop by twisting clockwise, and resume operations.
Post-Operation
Once the operation is complete, remove the machined part by opening the door and carefully dislodging the material from the bed.
Remove the end mill if no further operations are planned.
Clean any debris or chips from the machine bed and interior. Close the polycarbonate door and power down the machine.
