Usually, you need to prepare magnifying glasses with different magnifications from 3 to 12 times. The low magnification is mostly used for disassembly and assembly of parts, and the high magnification is used to adjust the balance spring and check whether the pendulum shaft has skewed or extremely small parts.

Usage: You can directly open the upper and lower eyelids to clamp the magnifying glass, or you can use iron wire or buy ready-made iron wire loops, and put the magnifying glass tightly on your head. The length of the iron wire can be adjusted by yourself, and people with nearsightedness and glasses can also directly Put it on the mirror and use it.

Usage:When using, it must be perpendicular to the machine board, and the size of the screw should be compared first, and the appropriate size should be selected, so as not to damage the screw cap or scratch the machine board due to careless sliding.

14. Diamagnetic tweezers and grindstone.



Application:To clamp the parts, in order to avoid the parts being magnetized, it is best to use the tweezers with anti magnetic function, which is usually enough to prepare 2-3 tweezers for use in the machine core.No. 3 tweezers or those with a thicker tip are usually used to clamp general parts such as machine core, splint, screw, gear, etc., while No. 5 tweezers or those with a thinner tip are used for small parts or adjusting hairspring isochrony, concentric circle and various fine works.

Usage:Don't use too much force. When clamping parts, don't clamp them flat. It's better to find a proper place to clamp them vertically, so as to avoid scratching the polished surface of parts due to improper force.

be careful:If the tweezers are blunt or missing corners, be sure to sharpen them with a grindstone. Do not use thin tweezers to clamp thick parts, or use thick tweezers to clamp small parts. This will easily cause damage to parts or tweezers.
