Abstract

The invention relates to a method for machining a stator opening of a stator and a bearing opening of an electromechanical converter, in particular an electric motor, the method comprising the steps of honing the stator opening using a honing tool and machining, preferably honing, the bearing opening.

1 . A method for machining a stator opening of a stator and a bearing opening of an electromechanical converter, the method comprising the steps of honing the stator opening using a honing tool and machining the bearing opening, characterized in that a tool for machining the bearing opening is aligned coaxially with the stator opening during the machining of the bearing opening via a centering device which engages in the stator opening, or in that the honing tool for honing the stator opening is aligned coaxially with the bearing opening via a centering device which engages in the bearing opening. 
     
     
         2 . The method according to  claim 1 , characterized in that the stator is joined to a housing section which comprises the bearing opening during the honing of the stator opening. 
     
     
         3 . The method according to  claim 1 , characterized in that the stator is not joined to a housing section which comprises the bearing opening during the honing of the stator opening. 
     
     
         4 . The method according to  claim 1 , characterized in that the stator opening is honed before the bearing opening is machined. 
     
     
         5 . The method according to  claim 1 , characterized in that the honing of the stator opening and the machining of the bearing opening take place simultaneously. 
     
     
         6 . The method according to  claim 1 , characterized in that the method after the honing of the first bearing opening, the stator opening comprises the attachment of a second housing section having a second bearing opening to the first housing section, which comprises the first bearing opening. 
     
     
         7 . The method according to  claim 1 , characterized in that the method after the honing of the stator opening and the machining of the first bearing opening comprises the machining of the second bearing opening, a tool for machining the second bearing opening being aligned coaxially with the stator opening or the first bearing opening via a centering device which engages in the stator opening or the first bearing opening during the machining of the second bearing opening. 
     
     
         8 . The method according to  claim 1 , characterized in that the machining of the first bearing opening and, where applicable, the second bearing opening comprises at least one of the machining steps among honing, fine boring and reaming. 
     
     
         9 . The method according to  claim 1 , characterized in that the stator opening is honed using honing stones with diamond as the cutting material and/or that the stator opening is honed using honing stones that have a cutting material with an average grain size that is smaller than the thickness of the lamina of the stator, and that the stator opening is honed using honing stones which have a cutting agent concentration of at most 20 vol %. 
     
     
         10 . The method according to  claim 1 , characterized in that the stator opening is honed with a honing angle of less than 30°. 
     
     
         11 . The method according to  claim 1 , characterized in that a centering device is used that is designed to be radially adjustable.
