How do I attach the magnetic base of the core drilling machine to a surface that is too thin, uneven or non-magnetizable?
Question:
How do I attach the magnetic base of the core drill to a surface that is too thin, uneven, not large enough or cannot be magnetized?
Answer:
When working on steel materials with a lower material thickness, the workpiece must be reinforced with an additional steel plate to ensure the magnetic holding force. The minimum material thickness can be found in the operating instructions for your machine. The additional steel plate must be attached by spot welding or with clamps.
For structured surfaces such as checker plate or tear plate, a vacuum plate order number 92602057017 and the vacuum pump order number 92601022013 are required.
For anti-magnetic workpieces such as stainless steel or copper and flat surfaces, a suction plate, order number 92602054016, is required.
Make sure that the surface on which the magnetic base is placed is even, clean and rust-free. Remove paint and filler layers.
The magnet must cover the entire surface of the material to be drilled. Even a slight reduction in the installation surface leads to a reduced magnetic holding force. Even the slightest feed force can cause the machine to lift off or slip. This represents a high work risk for the user. Suitable measures must be taken to increase the surface area.
