摘要:
A mounting element for holding a self-adhesive and/or flexible abrasive includes a supporting plate, and a distributing body. The supporting plate includes a plurality of suction openings which penetrate the supporting plate from a first side to a second side opposite the first side. A first side of the distributing body is in contact with the second side of the supporting plate, and a second side of the distributing body is configured to hold an abrasive. The distributing body includes a plurality of cavities which penetrate the distributing body from the first side of the distributing body to the second side of the distributing body, and which are mutually separated by a plurality of walls. At least one of the walls has at least one aperture which connects at least two adjacent cavities to each other.

A retaining body for a grinding structure, in particular a grinding wheel, includes a fixing layer with a fixing surface. The fixing surface has a fixing structure configured to fix a flexible grinding structure, and includes a support body with a support surface. The support surface supports a fixing layer retaining surface that lies opposite the fixing surface, and is connected to the retaining surface. The support body is air- and dust-permeable, and includes an air- and dust-permeable material. The fixing layer is configured such that the fixing surface is substantially air- and dust-permeable in a direction that runs substantially perpendicular to the fixing surface, and such that an air flow can pass from the fixing surface through the fixing layer in a substantially perpendicular manner relative to the fixing surface.

A pneumatic hand grinding tool has a supporting plate and a compressed-air pipe to be connected to a source of compressed air for driving the supporting plate. The supporting plate has a flat surface to which an abrasive sheet is to be attached by suction. For this purpose the supporting plate has ducts leading into the flat surface, which are connected to an ejector unit that forms a source of suction. The ejector unit is arranged on the tool and has members which connect the ejector unit to the compressed-air pipe.

Disclosed is a method that includes a step of applying glue including carrying out with a pad printing machine a sequence of steps in which is driven a transfer pad from a glue taking position to an applying position in which the distal surface of the transfer pad is in contact with one surface of one component of the tool; and then carrying out again at least once the sequence of steps, whereby the glue is applied at least twice onto the one surface of one component.

A tool (1) for surface finish machining, having a cushion (6) made of an elastic plastics foam, on the underside of which there is formed a working medium face (2) having working media or adhesives (8, 11, 12, 13) for the releasable attachment of working medium discs and on the top side of which there is formed a drive receptacle (4, 5) for application of work, is created as a product that is producible easily and non-critically in high volume, is extremely robust in use, is moisture-resistant and is able to withstand high rotational speeds, in that the elastic plastics foam consists of closed-cell expanded and fused-together particles of a thermoplastic elastomer (TPE).

A grinding wheel is suited for shaping glass, notably glass that is less than or equal to 4 mm thick. This grinding wheel has at least one abrasive portion formed of at least one metal binder and of diamonds distributed in the binder. The binder has a Rockwell B hardness of between 95 and 105 and is tungsten-based. The diamonds have a size of between 75 and 95 μm and a concentration of between 2.2 ct/cm3 and 2.64 ct/cm3. Glass, in particular for shaping motor-vehicle glazing units, can be shaped with this grinding wheel, making it possible to achieve travel speeds greater than or equal to 30 m/min.
摘要:
An apparatus according to the principles of the present invention includes a rotatable platen, a rigid plate member with a top surface and a bottom surface, includes pin members coupled to the rigid plate member which can be inserted into guide openings positioned within the rotatable platen, and a vacuum channel formed within the platen that enables removable mounting the rigid plate member to a top surface of the rotatable platen. The vacuum channel includes a cavity in the top surface of the platen. The rigid plate member adhesively holds the polishing pad to form a rigid plate assembly. A vacuum source coupled to the vacuum channel can be activated to create a vacuum within the vacuum channel to attract the rigid plate member to the platen. The platen can then used to polish work pieces contacting the polishing pad on the top surface of the rigid plate member.
