Lagun BM4 Universal Bedmill Installation Timelapse
Installing a Lagun universal bedmill is a significant undertaking that requires careful planning and a skilled team at every step of the process.
1. Laying a Quality Foundation
Your new bedmill is a significant investment costing many hundreds of thousands, do not cut corners with your foundation, it is crucial for ensuring long-term stability and accuracy of the machine.
• Choose a Suitable Location: The site should be free from vibrations, excessive moisture, and temperature fluctuations.
• Full technical foundation layout drawings and specifications are supplied to enable the correct foundation to be constructed.
• Cure the Concrete: Allow the concrete to cure. This ensures it reaches maximum strength. The longer you can leave it to cure before building, the better.
2. Building the Machine, Unpacking and Inspection
• Inspect the Components: Before assembly, inspect all parts for any damage during transit. Ensure all components are accounted for.
• Documentation: RFM, thoroughly read the assembly manual provided by the manufacturer.
Assembly
• Base and Column Installation: Position the base on the foundation. Secure the column to the base. Ensure it is rough levelled.
• Bed Installation (if not already assembled to base): The bed is the most critical part of the bedmill. It must be aligned perfectly with the base and column.
• Electrical and Hydraulic Connections: Connect the electrical and hydraulic systems. Ensure all connections are secure and follow the manufacturer’s wiring diagram.
• Mount the Head: Carefully mount the universal head.
3. Testing
Once the bedmill is assembled, the next step is to precision level and test.
Geometric Testing
• Levelling: Use precision levels to ensure the machine is level and stable in all axes. Adjusting the levelling screws to give readings recommended by Lagun.
• Squareness Test: Check the squareness of the machine using a granite square or an electronic squareness tester. Adjust until within manufacturers specification.
• Parallelism: Ensure the bed and the spindle are parallel. This can be checked using a dial indicator.
Calibration
• Spindle Alignment: Use a test bar to check the alignment of the spindle. Make necessary adjustments to ensure it is perfectly aligned.
• Axis Calibration: Calibrate each axis (X, Y, Z and C) using a laser interferometer or a ball bar system. This ensures that the movements are accurate and precise.
Functional Testing
• Dry Run: Perform a dry run without any load to ensure all movements are smooth and accurate. Check for any unusual noises or vibrations.
• Load Test: Gradually introduce load to the bedmill and monitor its performance. Ensure it maintains accuracy under load.
4. Final Adjustments and Safety Checks
Before putting the bedmill into full operation, perform the following final checks and adjustments:
Final Adjustments
• Re-check Levelling and Alignment: Re-check all levels and alignments after the initial tests. Make any necessary fine adjustments.
• Lubrication: Ensure all moving parts are properly lubricated. Follow the manufacturer’s guidelines for lubrication intervals and types of lubricants.
Safety Checks
• Emergency Stops: Test all emergency stop buttons to ensure they are functioning correctly.
• Guarding: Ensure all protective guards and shields are in place and secure and operating to CE/UKCA regulations.
• Training: Ensure all operators are trained in the safe operation of the bedmill.
Conclusion
Installing a universal bedmill is a meticulous process that requires attention to detail at every step. From laying a quality foundation to precise geometric testing and calibration, each phase is crucial to ensure the machine’s optimal performance and longevity. Remember, a well-installed bedmill is an investment in quality and efficiency for your manufacturing operations.
