The magnetic base of the magnetic drill makes it magnetic. The magnetic drill can be fixed on the designated steel beam for drilling purposes without shaking or shifting.
The magnetic drill is portable and highly efficient. After turning on the power of the magnetic drill, the electromagnet at the bottom of the magnetic drill will generate magnetic attraction. This magnetic attraction allows it to be firmly attached to the surface of the steel and has the function of fixing the work piece. The stronger the magnetic attraction, the stronger the adsorption capacity, so that the magnetic drill is more stable and accurate when working. Then the magnetic drill will drive the drill bit to rotate under the situation of high-speed rotation, which is the work of the drill bit for cutting and drilling, such as drilling or threading on the surface of the work piece. According to different drilling tasks, the drill bits used are different.
Because the magnetic drill has the function of adsorbing the work piece, it is very suitable for outdoor work, such as high-altitude operations that require precise drilling, then we need to use a magnetic drill. Or when we need to drill upside down, we need to consume a lot of force to fix the general drilling machine. If we have a magnetic drill, then we will work easier in these situations. The size of the magnetic drill is smaller than that of the general standing drilling machine, lightweight, high efficiency, and the key point is that it can be used to fix the work piece. Use its adsorption capacity to perform precise drilling at different angles. This type of magnetic drill is suitable for installation engineering, railway engineering, shipbuilding industry, steel engineering, bridge engineering, and other fields.
The magnetic drill is mainly composed of four structures: magnetic base, drill stand, gearbox, motor, arbour, and a control circuit. In terms of the speed control function, the magnetic drill is divided into gear speed control and step-less speed control. The gear speed can be adjusted according to the desired speed. The step-less speed regulation can change its speed without stopping the machine.
Types of magnetic drill
Horizontal magnetic drill
The horizontal magnetic drill is small in size and light in weight, so it is suitable for use in small spaces or operations that require airtight drilling. The frame and base of the horizontal magnetic drill can be adjusted back and forth and rotated left and right. In this way, precise positioning and operations can be performed on both sides.
Vertical magnetic drill
The vertical magnetic drill is the most commonly used magnetic drill. When operating, we only need to hold its handle to work at high altitudes or outdoors.
Pneumatic magnetic drill
The pneumatic magnetic drill is suitable for environments that are prone to fire or explosion hazards. Because this kind of magnetic drill is driven by compressed air, the safety goal has been achieved.
Types of magnetic drill bits
By using different drill bits, magnetic drills can be used for different purposes. The types of drill bits often used to link magnetic drills mainly include the following two types:
Twist drill bit: general twist drill bit can only reach 32mm at most
Core bit/Annular cutter: The core bit can be as high as 50mm to 100mm.
The drilling speed of a general core magnetic drill is more than 3 times faster than that of a twist magnetic drill. Core drills are faster and more accurate than twist drills. They can drill holes of specified size on steel plates of different thicknesses at a very fast speed with a small amount of power. Besides, the force required to operate the machine is also small, because there is no problem of concentricity and shaking of the drill bit so that the accuracy of the work is higher, but the core magnetic drill can only be used to drill through holes.
Magnetic drills need good maintenance to maintain their life and drilling accuracy.
Below we listed a few things to note:
Magnetic drills need to be stored in a dry, clean and safe environment
When disassembling the magnetic drill, we need to place each removed part, and we need to put all the parts back to their original corresponding positions during installation to prevent omissions during reinstallation.
When magnetic driving parts are drilled, lubricating oil must be frequently injected and cut and kept clean;
If the working time of the magnetic drill is too long and the motor heats up, we should suspend the use of it for some time, and wait for it to cool down a little, so as not to overheat and cause its motor to burn out.
It is necessary to regularly check the status of the power line, plug, switch off the magnetic drill, whether the transmission parts are damaged, whether the resistance of the magnetic base is normal, whether there is leakage, etc. (But while checking the magnetic drill, we must first unplug the switching power supply to ensure our safety.)
If the magnetic drill has not been used for a long time, we must remove its drill bit, keep the drill bit and the drill handle clean, and take measures to prevent rust. To make sure that it can be used again when you plan to reuse it later.
