A sintering press for producing a sintered connection between a first connection partner and a second connection partner disposed thereabove, having a suction-fixing installation for fixing the first connection partner, having a compression piece which is disposed above the suction-fixing installation. The sintering press for producing the sintered connection is configured for converging the compression piece and the suction-fixing installation relative to one another and for mutually compressing the first connection partner and the second connection partner, wherein the suction-fixing installation on the side thereof that faces the compression piece has first suction openings, wherein the suction-fixing installation, when the first connection partner is disposed above the first suction openings, by generating a negative pressure at the first suction openings, is configured for suctioning the first connection partner and, on account thereof, for fixing the latter in relation to the suction-fixing installation. The invention furthermore relates to a pressure sintering method for producing a sintered connection by the sintering press.

A pneumatic plug gauge has been developed in the context of the invention. This plug gauge comprises a first measuring channel which can be connected to a pressure medium source and opens into a first outlet for the pressure medium, which outlet can be directed to a surface of the workpiece to be tested. According to the invention, this plug gauge is designed to determine the tilt angle between a section on the surface thereof and a region opposite this section on the surface of the workpiece by virtue of the first outlet being arranged at one end of the section and at least one second outlet being provided, which second outlet is arranged at the other end of the section. It has been recognized that the admittedly high precision of pneumatic length measurements can be converted in a particularly advantageous manner to high precision of the angle measurement in this manner. The tilt angle can be measured at least with an accuracy of less than one tenth of a degree. At the same time, the measurement is fast enough for 100% control in mass production. The plug gauge is the central element in the measuring system and in the method, to which the invention likewise relates.
