Specification of this 801
 
Nail drill maintenance. Because the hand-held miniature high-precision electric grinding and engraving machine generates a lot of dust during work, it needs to be cleaned frequently. The control box uses a hair dryer (opened in the cold air) to face the cooling holes to prevent dust accumulation. Brushed mobile phone work time is about 500 hours. It is necessary to check whether the carbon brush has worn out. If the carbon brush has consumed 2/3 of the length, the copper wire is exposed in the center, and the carbon brush must be replaced, otherwise the rotor of the motor will wear out. Directly affects motor life.
 
The hand-held miniature high-precision electric grinding and engraving machine works at high speed, so the bearing is its consumables. The general head bearing can work for 1000-1500 hours (the different forces of processing different materials, personal operation habits) The different sizes of dust particles produced by different materials and different materials have different hazards to the bearings. Generally, the noise emitted by the bearings will gradually become larger, the sound will become softer, and the runout of the shaft will increase. When you need to send a professional maintenance department to replace the bearing, otherwise it will cause damage to other parts. The 30V mobile phone has four bearings, two heads and two rear motor parts. Because the power is in the head when working, so The two lifespans of the head are shorter than those of the rear motor part, generally about 1/2 of the motor part of the bearing. In contrast to the two of the heads, the front is more likely to be bad than the back, generally 1 /3 or so.
