摘要:
The milling tool (1) has a spindle (2, 3), which is mounted in a housing (8) and carries a milling head (14) fitted with cutting inserts (15). Arranged in the drive train of the milling head (14) is a torque-transmitting resilient coupling (13). The spindle (2, 3) actually comprises spindle parts (2, 3) that are connected by a plug-in connection via a bearing bush (9, 10) and can be turned with respect to each other, and the coupling (13) is arranged between these spindle parts. The resilient coupling comprises a helical spring (13) that is fastened by each of its ends to a spindle part (2, 3). The milling head (14) is fitted with sharp-edged cutting inserts (15), which have a wedge angle of 40 - 75° and have on the milling head (14) a position in which they operate with a positive rake angle of at least 6° and a clearance angle of at least 6°.
摘要:
The invention relates to a milling head for milling chamfers, especially for a mobile chamfer miller, comprising successive seats for blanking dies, said seats having a position in which the blanking dies with a leading edge angle of between 40 and 75° operate respectively on average with a positive effective cutting angle of at least 6° and a clearance angle of at least 6°, and are provided for a border comprising blanking dies with a staggered arrangement of the cutting edges, such that respectively only one cutting edge length of 15 mm, preferably 12 mm, at the most, is active. Said measures increase the cutting performance of the milling head. The reduced cutting edge length can be formed on a long blanking die instead of using a shorter blanking die, in such a way that the cutting edge is interrupted by cavities or other e.g. flat triangular recesses on the surface of the blanking die. The staggered arrangement is then comparatively small.

The invention relates to a cutting disc (7) and a carrier body (6) for a cutting wheel (5) for forming a bevel on an edge of a workpiece, in particular a metal sheet or a pipe, said cutting wheel having a cutting edge (4) by means of which material is severable from the workpiece. According to the invention, the cutting wheel (5) comprises a carrier body (6) for the cutting disc (7) and the cutting disc (7) has a cutting edge (4) by means of which material is separable from the edge (2), and is provided with devices (8-12) for detachably fastening said cutting disc to the carrier body (6). The carrier body (6) according to the invention is provided with devices for detachably fastening the cutting disc (7) to the carrier body. Expediently, the carrier body is a carrier wheel (6) and the cutting disc (7) and/or the carrier wheel (6) is/are formed in a conical manner. Preferably, the cutting disc (7) is provided with a recess (10, 11) for receiving at least one retaining and/or fastening means (8, 9, 27, 28). In one embodiment of the invention, at least one main face (13, 14) of the cutting disc (7), on which the cutting edge (4) is provided, has a planar surface, apart from the optionally provided recesses (10, 11), for easy grindability.

The invention relates to a manual grinding tool comprising a rotating grinding head (7). The inventive grinding device is characterised by a guiding device that is connected to the grinding tool (8) and can be applied to a workpiece (19) in a sliding and/or rolling manner. The grinding head (7) assumes a fixed position in terms of the guiding device which is used to press the grinding tool against the workpiece (19) in at least one direction without tilting.

摘要:
The invention relates to an apparatus for forming a bevel on an edge of a metal sheet (1) or of a pipe, said apparatus comprising a bevelling device which has a tool, which is driven by means of a drive and machines the metal sheet or the pipe, and a guide device, which supports the metal sheet or the pipe. According to the invention, the bevelling device is mounted in the apparatus, preferably in a carrying device (8) of the apparatus.
摘要:
The invention pertains to a method and device for producing an aerosol. According to the invention, a particle former is applied onto one side of a permeable wall, through which it is pressed by means of a pressurized gas, resulting in the formation of fluid particles. The inventive method enables fluid particle streams with very low kinetic energy per particle to be formed, which can be used for example for treating, especially cooling, easily deformable objects. Other applications, including as a burner, rest upon the reactive capacity of the particle gas mixtures obtained according to the invention.
