Introduction To The Principles Of Electric Shavers

The electric shaver uses an electric motor to drive the movable blade to move relative to the fixed blade to cut off the beard or hair that enters the mesh.
The quality of the shaving effect is mainly determined by the accuracy of the fit between the fixed blade and the movable blade. It requires that the spherical curvature of the fixed blade and the movable blade must be properly matched, and at the same time, there must be a pressure distance of about 1mm and a certain shearing angle between the two blades. If the pressure distance is too small, the shave will not be sharp and the hair will feel like plucking; if the pressure distance is too large, the power consumption will be high and the blade will be severely worn, and it will also make a sharp abnormal sound.
The fixed knife adopts mesh shape. Different manufacturers have different mesh patterns, but they can keep the fixed blade and movable blade at a certain shearing angle, and ensure a high hair entry rate. The production process of the fixed blade is different, and its use effect is also different. Fixed blades that use stamping, corrosion, and then stamping processes have poor edge sharpness, average skin feel, few changes in texture, rough lines, and not very long service life. The fixed blade using electroforming, stretch grinding, and stamping milling processing technology has good sharpness, comfortable skin feel, fine lines, and long service life.
The movable blades are evenly distributed on the movable tool holder, and the movable tool holder is required to have no obvious radial runout to maintain the rotational balance of the movable tool holder, and with the corresponding rotation speed, the relative motion between the fixed blade and the movable blade is in a shaving state. In this way, no matter how many moving blades there are, you can achieve the purpose of shaving sharply.
