Die electric grinding, also known as electric grinding drill. Generally, DC motor with AC voltage is used, which has the characteristics of high speed, large torque and high power. It has a speed regulating gear, which can generally be adjusted between 0 and 30,000 revolutions. It can effectively cut, trim, trim and polish metals, plastics, plexiglass, glass, wood and so on with various cutting abrasive belts and abrasives. The tool has high safety factor, is compact and convenient, and is easy to use.
At present, there are many brands of electric grinding drills on the market, and a large number of manufacturers at home and abroad produce and manufacture this practical tool. Prices vary greatly, ranging from several hundred yuan to thousands of yuan, and the quality of products is also mixed, which brings certain difficulties to the choice. According to my personal experience, I recommend you to use all kinds of flying tower electric grinding drills and their electric grinding flexible shafts (handles) produced by "Guangdong Dongguan Taifei Electronics Co., Ltd.", which have various styles, high quality and low price. Just pay attention to the following points when choosing such tools.
Choose a satisfactory electric grinding drill;
(1), pay attention to whether it is the brand of a regular manufacturer. Regular manufacturers have complete products with "three certificates", passed "3C" certification, complete accessories, perfect after-sales service and are trustworthy.
(2) High-quality electric grinding drill adopts high-quality motor and engineering plastics, adopts double insulation structure, is safe and reliable, and has built-in interference suppressor to prevent interference with TV, radio and radio instruments and equipment. Reasonable design, good feel and exquisiteness are the products of some small workshops that cut corners. Small "inconspicuous" places such as switches, governors and power lines can more intuitively reflect the quality requirements and process standards of manufacturers. Choosing products with acceptable quality is undoubtedly an additional guarantee of safety and durability.
(3) Another intuitive identification method is to put two or more electric grinding drills together and identify them by sound after power-on, because the current electric grinding drills are mostly adjustable in the range of 0 to 30,000 revolutions, and the high-quality electric grinding drills have high power and fast acceleration, while the poor power and acceleration are weak, obviously lacking power, failing to reach the nominal value and even having abnormal noise, so it is difficult to guarantee the quality of such products.
Use of electric mill and its accessories: safety matters
1: When installing the flexible shaft or replacing the grinding head, be sure to unplug the power supply!
2. The chuck between the flexible shaft and the fuselage, and the chuck between the flexible shaft and the grinding head must be locked with a small wrench.
3. When the electric mill is powered on, the power switch must be turned off.
4. Before processing, the workpiece should be fixed firmly, and the electric mill should be turned for trial operation (no load). After confirming that there is no abnormality, the processing operation can be carried out.
5: Before operation and use, carefully check the grinding heads used, and it is forbidden to use worn or cracked grinding heads.
6: Wear protective glasses when using tools.
7: When processing parts. The pressure exerted by hands on the electric mill should be properly controlled to avoid overexertion.
8. When using the cutting piece for processing, be sure to ensure that the personnel deviate from the tangent direction of the cutting piece to prevent the flying piece of the cutting piece from hurting people.
The flexible shaft (handle) of the electric mill transmits power to the gearbox, and the transmission ratio from the output shaft of the gearbox to the wheels is constant. There is a "flexible shaft" on the output shaft of the gearbox, which leads to the odometer in front of the driver. The so-called "soft shaft" is a spiral pipe with steel wire core, like the cable of bicycle brake. There is lubricating oil between the pipe wall and the inner core. The outer tube is fixed and the inner core can rotate. The rotation speed of this kernel has a constant proportional relationship with the rotation speed of the wheel. The flexible shaft is connected with the speedometer, so that the pointer can indicate the driving speed of the car. At the same time, the rotation of the flexible shaft is transmitted to the roller counter in the middle of the odometer through the worm wheel and worm, and the mileage represented by the wheel revolutions is accumulated. Because the speed and mileage are driven by the rotation of the same flexible shaft, the two tables are together, the former is indicated by the pointer and the latter is accumulated by the roller counter.
The quality of domestic brands is not bad. I recommend several electric mills and flexible shaft handles produced by Dongguan Toffee Electronics Co., Ltd. on the market: 1, Feita mini electric mill jade carving polishing mini electric drill hanging grinding accessories 2, Feita electric mill engraving machine multifunctional high-power polishing amber beeswax wood carving set 21/set 3, electric mill electric drill chuck handle flexible shaft 0.3-4mm.
