The invention relates to a reducing ring having a reducing segment 6 comprising an outer diameter for inserting in the central hole of a cutoff grinder grinding disc 3 and an inner diameter for centering relative to the centering area 4 of a clamping flange 1, comprising a contact area formed by a collar 7 having an outer diameter greater than the outer diameter of the reducing segment 6.
摘要:
Die Erfindung betrifft ein Verfahren zur Herstellung einer Lamellenschleifscheibe mit einem insbesondere tellerförmigen Träger, der rotierend um eine Achse antreibbar ist und der eine Mehrzahl von sich schindelartig überlappenden Schleiflamellen trägt, wobei die Schleiflamellen auf einem ringförmigen auf der Achse zentrierten Trägerabschnitt befestigt, insbesondere aufgeklebt werden, wobei ein Band (1) eines Schleifmittels einer Vorrichtung zum Bestücken zugeführt wird, wobei aus dem Band (1) geschnittene Schleiflamellen auf den Trägerabschnitt aufgebracht werden, wobei der Vorrichtung zum Bestücken ein Band (1) zugeführt wird, welches ein Trägerband (2) umfasst, auf dem ein Schleifvlies (3) aufgebracht ist, und auf dessen von dem Schleifvlies (3) abgewandten Seite Fasern (4) überstehen, und wobei vor dem Schneiden der Schleiflamellen aus dem Band (1) in einem zusätzlichen Verfahrensschritt die freie Länge und/oder die Anzahl der überstehenden Fasern (4) verringert wird.
摘要:
The invention relates to an abrasive point for machining work pieces made of metal, in particular of cast metal, having a base body with a grinding region effective on the outer surface for grinding the work piece and a shaft for clamping the tool in the collet chuck of a machine, wherein the base body is produced from metal and wherein the outer surface of the base body has abrasive particles that are held on said surface in a firmly bonded manner.
摘要:
Disclosed is a separating and grinding device comprising a drive unit, a working spindle (12), and a clamping flange (14) and a nut (16) for clamping a tool (18) to the working spindle (12) through the hub bore of the tool (18). Vibration-damping means (26) made of elastic material are arranged between the tool (12) and the nut (16). The nut is embodied as a collar nut (16). The vibration-damping means are provided in the form of a tube piece (26) between the internal face of the hub bore (19) of the tool (12) and the external face of the collar region (20) of the collar nut (16). The tube piece (26) is provided with an excess axial length before being assembled or is compressed in the assembled state.
