The invention relates to a grinding disc (10, 110, 210) for a grinding machine (90), wherein the grinding disc has a machine side (11) associated with the grinding machine (90) and a processing surface (12, 112, 212) associated with a processing of a work piece (V), wherein a tool holder retaining means (15) for securing to a tool holder (92) of the grinding machine (90) is arranged on the machine side (11), and a grinding means (50) for processing a work piece (V) or retaining means (33) for detachably retaining a grinding means (50) of this type are arranged on the processing surface (12, 112, 212). According to the invention, the processing surface (12, 112, 212) of the grinding disc (10, 110, 210) has a ring-shaped edge region (44, 144, 244) for forming a flat contact surface of the grinding means (50) on the work piece (V), and a central region (45, 145, 245) surrounded by the ring-shaped edge region (44, 144, 244), wherein the ring-shaped edge region (44, 144, 244) projects in front of the central region (45, 145, 245) towards the work piece (V) and/or wherein the grinding disc (10, 110, 210) has a smaller bulk modulus in the central region (45, 145, 245) than in the edge region (44, 144, 244), such that, when a contact pressure (P) is applied to the tool holder retaining means (15) in the direction of the processing surface (12, 112, 212), substantially the edge region (44, 144, 244) is loaded in the direction of the work piece (V), or same is in contact with the work piece (V), for abrasive processing of the work piece (V).
摘要:
An apparatus (100) for replacing an abrasive sheet (25) in a sanding machine (120) comprising a working head (50) in which it is provided a support body (10) having an engagement surface (15) arranged to engage with an abrasive sheet (25). The sanding machine (120) also comprises a handling device (40) arranged to actuate the support body (10) in space according to at least two degrees of freedom. The face (26) of the abrasive sheet (25) facing, in use, towards the support body (10) and the engagement surface (15) of this comprises a mutual engagement means of removable type. For example, the mutual engagement means can provide a layer of Velcro, i.e. a velvet layer on a face and a plurality of hooks on the other face, or an adhesive layer, in particular of reversible glue layer, or a plurality of projections and recesses mutually engageable with each other, or similar engagement elements. Furthermore, an application station (70) is provided in which an abrasive sheet is mounted at the engagement surface of the support body (10).

The invention relates to a vulcanized fiber grinding tool (1) comprising two vulcanized fiber grinding disks (2, 3) which are adhered to each other over the entire surface by means of an adhesive layer (4) arranged between the vulcanized fiber grinding disks (2, 3) such that the vulcanized fiber grinding disk (2, 3) outer faces provided with the grinding means point away from each other and the use of a support plate is not necessary.
摘要:
A hand sander (102) and sanding disc fixture for attaching a sanding disc (104) to a hand sander (102) includes a table (106) have a top (108) with a sander storage station (120) and an application station (124) thereon. The storage station (122) has a holder (150) holding a hand sander (102) having a sander pad (130). The application station (124) has at least two datum pegs (190) extending from the top (108) of the table (106) that hold a stack (128) of sanding discs (104) with attaching sides of the sanding discs (104) facing away from the top (108) of the table (106). The datum pegs (190) pass through datum holes (174) in the sanding discs (104). The datum pegs (190) having datum surfaces configured to be received in datum notches (142) in an outer diameter of the sander pad (130). The datum pegs (190) align the sander pad (130) with the sanding discs (104) when the sander pad (130) is pressed against the attaching side of the outermost sanding disc.
