The objective of this most recent product development for HSS core drills was to produce a range of core drills optimised for power with greater heat resistance and better protection against wear. The desired results were achieved by an enhanced proportion of cobalt in special steel. Combined with speed-controlled BDS magnetic core drilling machines, these core drills are adapted for high loads in … Continue reading What are the advantages of HSS Cobalt annular cutters?
The ejector pin or also called as pilot pin has 3 major functions: Centring: The ejector pin is exactly positioned to the centre punch mark. Switch the magnet on and the machine and tool are in the drilling position. Oiling: By means of the automatic internal lubrication, cutting oil is supplied via the ejector pin … Continue reading What is the advantage of an ejector pin of annular cutter?
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?
It is the same as we calculate the RPM for magnetic drilling machine. 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 … Continue reading How to calculate the speed for an annular cutter?
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?
Do not use the machine in flammable or potentially explosive environments. Persons who due to their physical, mental or motor response abilities are unable to operate the machine safely may only use the machine under supervision or instruction by a responsible person. Persons with heart pacemakers or other medical implants must not use this machine. … Continue reading What are the fundamental safety precautions for using a magnetic drilling machine?
