Watch production is characterized by small parts size, high processing accuracy, high finish requirements, fine process equipment, high degree of mechanization and automation.
Raw materials of watches
There are many raw materials for the manufacture of watches. There are strict requirements for the performance, surface state and dimensional accuracy of materials. Such as the manufacture of spring material, requiring high strength, antimagnetic, temperature change is small, is made of a special stainless, constant elastic alloy material; The spring of the watch is to drive the whole machine heart kept running power components, which requires the use of stainless, not easy to break, high strength, high elastic materials to manufacture; the "diamond", is a kind of hardness is particularly high, especially good finish artificial gem, in order to improve the flexible operation and wear resistance of parts, prolong the service life of the child table.
Parts processing
Watch in the processing of various parts, quality requirements are very strict. For example - a pendulum wheel journal as thick as a hair, its tolerance is only 0.005 mm, with a 40-fold microscope inspection, and then riveted with the balance wheel;
Watch assembly and quality check
The final stage of making a watch is to assemble all the parts that have been processed and inspected. The assembly of the watch, the requirements are very strict, is in a clean, constant temperature workshop with air conditioning equipment. When you walk into the watch assembly workshop flow line visit, you will see rows of rows of assembly workers wearing white coats, white hats, slippers, rubber fingers, like the doctor in the operating room, carefully assembled and adjusted the heart of the watch. The smallest screw in the watch is much smaller than a sesame seed. A pendulum journal, on the other hand, is as thin as a human hair, so that assembly can only be carefully adjusted with a microscope magnified tens of times. To the escapement mechanism parts, to use a projector magnification of 50 times, one by one inspection. When a watch assembly is completed, but also for more than ten days of comprehensive calibration, after simulation, real go, seconds, vibration measurement, electrical calibration instrument test, appearance and other items, qualified before arrange delivery.
When you buy a new watch, joy to wear wrist, you have thought of the watch production process, choice of raw materials, processing of various parts to the final assembly of finished products, double inspection before delivery, the majority of watchmaking workers and technicians to go through how many complex and precise processing procedures.
