The magnetic drilling machines are provided with speed gears and some machines are also equipped with variable speed control. As per the diameter of the annular cutter and the type of annular cutter the speed of the magnetic drilling machine has to be set. The formula for calculating the speed is: d = diameter of the … Continue reading How to set the RPM for magnetic drilling machine?
How to clamp the magnet on FERROUS material or magnetic material? The magnet clamping force is dependent on the condition of the substrate. The clamping force is significantly reduced by paint, zinc and scale coatings and rust. The substrate must satisfy the following preconditions in order that a sufficient magnet clamping force can be achieved: The substrate must be … Continue reading How to clamp the magnet on ferrous and non-ferrous material or non-magnetic material?
