Introduction to the production process of watch case
The production process of the case
-- watch case making
Today I finished the production of the watch case to share with you.
1. Design the diagram
Watch drawing is generally divided into plane plotter (drawing into the table mostly) and structure plotter. I will make the shell as an example. My draftsman will first draw the diagram into the table. I usually draw the plane, 3D and rendering drawings to make sure the appearance details are OK. Provide the 3D drawing and assembly drawing to the shell factory draftsman, who will draw the structural data drawing and send it to our engineer for drawing review and confirmation. If there is no problem, we will start the work. (Usually we will make samples first, and confirm that the samples are OK before mass production) 3D drawing.
2. Processing
According to the drawing table embryo factory to do a good job of embryo, with steel plate press out the approximate shape of the watch
The embryo should be coarsed by the oil machine and the embryo allowance should be kept wide (generally 0.5mm)
Oil machine
After the rough operation of the oil machine, the nc machine (automatic lathe) has finished the machining. According to the exact data of the drawing, generally the internal structure is directly and accurately in place (generally the tolerance range of 3-5c is allowed, 1c=0.01mm for a hair is about 8c).
NC machine
After that, the drilling machine drills the holes and ear holes and then returns to the oil machine to grind on the bottom (left in the final processing outside because of the fear of the front steps bump against the outside). I give an example of this table to finish these steps on the mill

3. Mill grinding
Mill is the most important part of the whole case processing, above according to the case standard grade good standard data. To ensure that the internal structure is correct and reasonable, the appearance of grinding all in the mill craft above.
I have a specific example of the above type of sanding steps
