3. Safety Information
Always prioritize safety when operating CNC machinery and accessories. Read and understand all instructions before use.
- Ensure the vacuum pump (not included) is properly connected and functioning before securing any workpiece.
- Verify the workpiece is firmly held by the vacuum before beginning any milling operation.
- Do not attempt to mill workpieces that are too small or irregularly shaped to achieve a complete seal with the vacuum pod.
- Wear appropriate personal protective equipment (PPE), including eye protection, during CNC operations.
- Keep hands and loose clothing away from moving parts of the CNC machine.
4. Setup
4.1 Mounting the Vacuum Clamp Pod
The vacuum clamp pod can be mounted on MDF/aluminum boards with M6 screw holes or hybrid tables with T-slot tracks.
- Position the vacuum clamp pod on your CNC machine's work surface.
- Align the mounting holes on the pod with the M6 screw holes or T-slots on your table.
- Insert the M6 screws through the pod's mounting holes and secure them with the M6 T-nuts (for T-slots) or directly into threaded holes.
- Tighten the screws firmly to ensure the pod is stable and does not move during operation.
4.2 Connecting to a Vacuum Pump
This vacuum pod kit requires an external vacuum pump (not included) for operation. The kit includes various air tubes and connectors for compatibility.
- Select the appropriate air tube (Φ6mm or Φ8mm) and air tube fittings (6mm to 8mm, 8mm to 10mm) that match your vacuum pump system.
- Connect one end of the air tube to the pneumatic air fitting on the vacuum clamp pod.
- Connect the other end of the air tube (using adapters if necessary) to your vacuum pump.
- Ensure all connections are secure and airtight to prevent vacuum leaks. Applying Teflon tape to threaded fittings can help create a better seal.
5. Operating Instructions
5.1 Selecting the Correct O-Ring
The kit includes multiple sizes of rubber O-rings (Φ24mm, Φ40mm, Φ60mm, Φ95mm) to accommodate different workpiece sizes. Only one seal ring should be used at a time.
- Choose an O-ring that is slightly smaller than the workpiece's footprint to ensure the workpiece covers the entire rubber sealing area.
- Place the selected O-ring into the corresponding groove on the vacuum clamp pod.
- Ensure the O-ring is seated properly and free from debris to create an effective seal.
5.2 Securing a Workpiece
The vacuum clamp pod is designed to hold workpieces with a flat bottom surface that can cover the chosen O-ring entirely.
- Place the workpiece onto the vacuum clamp pod, ensuring it completely covers the O-ring.
- Turn on your external vacuum pump.
- The vacuum will create a strong hold, securing the workpiece in place.
- Gently test the workpiece to confirm it is firmly held before starting any CNC operations.
The integrated length scale on the vacuum pod surface assists with quick and accurate measurements for workpiece placement.
6. Maintenance
- Cleaning: Regularly clean the surface of the vacuum clamp pod and the O-rings to remove dust, chips, and debris. A clean surface ensures a proper vacuum seal.
- O-Ring Inspection: Periodically inspect the rubber O-rings for any signs of wear, cracks, or damage. Replace worn O-rings to maintain optimal vacuum performance.
- Air Connections: Check all air tube connections and fittings for leaks. Tighten any loose connections and replace damaged tubes or fittings as needed.
- Storage: Store the vacuum clamp pod in a clean, dry environment when not in use to prevent damage and prolong its lifespan.
