Definitions

  • the invention relates to a part for a timepiece movement and in particular to a non-magnetic watch component for a mechanical timepiece movement and in particular to a balance axis, an anchor rod and a non-magnetic escapement pinion.
  • the manufacture of a watch component comprising at least one part having the shape of a part of revolution, such as a watch pivot axis, consists, from a hardenable steel bar, in carrying out machining operations by removing chips, such as bar turning, to define different active surfaces (bearing, shoulder, pivots, etc.) and then subjecting the machined watch component to heat treatment operations comprising at least one quenching to improve the hardness of said component and a or several incomes to improve tenacity.
  • the heat treatment operations can be followed by an operation of rolling the pins of the pins, an operation consisting in polishing the pins to bring them to the required dimensions.
  • the hardness as well as the roughness of the pivots are further improved. It will be noted that this rolling operation is very difficult or even impossible to carry out with most materials whose hardness is low, that is to say less than 600HV.
  • the pivot axes for example the balance axes, conventionally used in mechanical watch movements are produced in grades of free-cutting steels which are generally steels. Carbon martensitics including lead and manganese sulphides to improve their machinability. A steel of this type designated 20AP is typically used for these applications.
  • This type of material has the advantage of being easily machinable, in particular of being suitable for bar turning and exhibits, after quenching and tempering treatments, high mechanical properties which are very advantageous for the production of horological pivot axes.
  • These steels exhibit in particular high wear resistance and hardness after heat treatment.
  • the hardness of the pivots of an axle made of 20 AP steel can reach a hardness exceeding 700 HV after heat treatment and rolling.
  • this type of material has the drawback of being magnetic and of being able to disturb the operation of a watch after having been subjected to a magnetic field, and this in particular. when this material is used for the production of a balance axis cooperating with a spring balance made of ferromagnetic material. This phenomenon is well known to those skilled in the art. It will also be noted that these martensitic steels are also sensitive to corrosion.
  • austenitic stainless steels which have the particularity of being non-magnetic, that is to say of the paramagnetic or diamagnetic or antiferromagnetic type.
  • these austenitic steels have a crystallographic structure that does not allow them to be quenched and to achieve hardnesses and therefore wear resistance compatible with the requirements required for the production of clockwork pivot axes.
  • One means of increasing the hardness of these steels is work hardening, however this hardening operation does not allow hardness greater than 500 HV to be obtained. Therefore, in the context of parts requiring high resistance to frictional wear and having to have pivots with little or no risk of deformation, the use of this type of steels remains limited.
