(Summary description)Tiny precision gears also have their advantages and disadvantages.

In the grinding process of the traditional watchmaking process, the traditional bevel gear must be made by hand. First, the toothless gear is ground rough, and then the custom tool is milled from the original shape of the original gear, and then the professional hand-held milling machine is used, and the customized special tool is used. Milling cutter, one tooth is continuously positioned until the gear is cut to no edge for fine and precise use. The manufacture of bevel gears is not as complicated as it used to be. Expensive brands with higher quality requirements will first punch out the blanks, and then string them into a whole string. Then, the tooth profiles are milled out one by one with professional processing machine tools and professional gear milling tools, and then riveted with steel pinions.

They are not so picky about mass production, high-precision molds can be directly stamped and formed, and tiny gold and steel grit can be directly added to gears and rolled into drums to remove burrs. The steel pinions and technology on the precision gears are mirror polished, as long as there is a flat part, it is also mirror polished. Modern production looks like roll-polished electroplating, without the finesse and beauty of the old. The escape wheel part is ancient and delicate, not only the tooth shape of the precision gear looks more beautiful than modern ones, but also the frictional contact surface between it and the gemstone is very small, so the escape wheel is first ground on both sides to meet the level and the thinnest To reduce weight, the tail end will retain a certain thickness, which is about twice the thickness of the gear bracket, and then fully mirror-finished to prevent the spread and loss of lubricating oil due to other phenomena. The end of the bevel gear will be polished with a double-sided bevel, leaving a hair-thin contact surface in the middle to reduce the frictional resistance between the gems, so theoretically, the contact area is small and easy to wear, so the material of the steel must be good.
