In 1895, Germanys Pan -Voice created the worlds first DC flashing diamond.The shell is made of cast iron and can drill 4mm holes on the steel plate.Flash diamonds are a convenient small drilling tool, which consists of small electric motors, control switches, drill chips, and drills.
Flashlight drill repair
The first type of failure, the motor cannot work properly, should be disassembled to drive the electric drilling fuselage to check if the fuse is broken or the power cord is burned. If there is such a problem, it should be replaced immediately.Or the damage of the stator winding must be replaced or repaired by the winding winding; it may also be due to the rust of the bearings, which should be bearing and lubricating oil or rust removal treatment.The second type of failure, the speed of the motor slows down, is caused by severe wear, and should be replaced immediately.The third type of failure, the motor noise is too large, which is caused by the wear of the brush or bearings, which must be replaced by the brush and the bearings.The short -circuit of the agent winding is due to the damage of the insulation surface of the adjacent coil in the coil of the agent winding, which causes the coil to be powerless, which affects the normal work.
The difference between flashlight drill and impact drill
Electric diamonds have only rotation methods, which are especially suitable for drilling on materials that need small force, such as cork, metal, tiles, tiles, etc.The impact drill relies on rotation and impact to work.A single impact is very mild, but the impact frequency of more than 40,000 times per minute can generate continuous force.Shock drill can be used for natural stones or concrete.They are general, because they can use the "single diamond" mode or the "impact drill" mode, so for professionals and themselves, it is a basic electric tool worth choosing.
Flashlight drill model
There are many flashlight drill models, and there are naturally many classifications.We are divided into two types based on its structure, that is, one -way single -speed diamonds and more speed diamonds.The scope of use of the flash diamond is divided into standard, heavy and light type.The output power and torque of heavy electrical drills are relatively large, mainly used for drilling of high -quality steel and various other steel. It has high drilling efficiency and can apply large axial force.Small, it is mainly used for drilling of non -ferrous metals, cast iron, plastic and other materials. Ordinary steel can also be used, but it cannot be applied to axial force.The performance and use range of standard electric drills are between heavy and light types.
