9.2.2. Disposal of assembled balance spring substances

 

Separated from the main body, the assembled balance spring substances retain a high compression rate inside, so they should be completely disposed of in accordance with the following procedures. Also, small amounts of grease remain inside. This grease needs to be treated with great care in an environment sensitive to pollution.

 

Fix the assembled balance spring substances firmly on working areas with devices such as a vice.

As shown in [Figure 9.2] below, perforate the balance spring tube with an oxygen cutter. The hole shown in the Figure is the maximum size possible that can be perforated.

Cut the inside assembled spring into 4 to 5 pieces with an oxygen cutter. As two springs are assembled together, the cutting process shall be formed from the external to the internal side. After cutting, please check that there is no compression remaining in the spring.
