Abstract
A method of manufacturing a base body of a weighing sensor of a high-precision balance in which a base body is machined out of a monolithic metal block and has at least one arm which is hinged to the rest of the metal block via integral bending spring joints in the form of thin spots. The base body is then acted upon with a chemical solution at least at the bending spring joints to cause a material removal at these points. Furthermore, a base body manufactured by this method is presented.

A method of manufacturing a base body of a weighing sensor of a balance, characterized by the following steps:
- A) a base body or part of a base body is machined out of a monolithic metal block, forming at least one arm which is connected to the rest of the metal block via integral bending spring joints in the form of thin spots, and
- B) the machined base body or the part of the base body is exposed at least at the bending spring joints to a chemical solution, which causes a material removal at the bending spring joints.
