Abstract (en)

[origin: ES8705278A1] An apparatus for grinding and lapping sealing surfaces in slide valves and the like in situ or in the workshop has a base plate (21), a drive (6), and a rotatably mounted tool plate (3) which is connected to the drive (6) by a supporting element (4) and coupled to it by a transmission element. The supporting element (b 4) is supported releasably and with adjustable height on the base plate (21) by means of a clamping piece (7) of adjustable height and a guide piece (11 36). The guide piece (11 36) is mounted pivotably on the base plate (21). Rigidly connected to the guide piece (11 36) is a rocker (16) which is adjustable relative to the base plate (21) at one end. The strain occurring when such adjustment is made, in the rocker (16), the support (25) of the correcting element (28), the tool plate (3) or the other components which conduct force and/or moment, is assessed as a measure of the contact pressure of the tool plate (3). The strain may be indicated by a digital display (32) or a micrometer dial gauge (39).
