Description of the invention (Central Standards of the Ministry of Economy 印 Stamp of Consumer Cooperatives ^ Λ 'ΙΓ The present invention relates to a kind of cutting tools for work pieces, especially about— A kind of tool held in a hand-held power tool. The premise type of tool refers to the processing of the shape and / or surface of work pieces of different materials. In addition to the manufacturing of the hand guards in the workplace, I am interested in the so-called home crafts. Θ These cutting tools often cause problems due to the hard structure of the tool's steel system, even if small interference movements on the tool will negatively affect the uniform cutting Λ Even if the A slight tilt of the machine tool will also affect the change of the set angle between the tool and the work piece, causing damage or flaws on the surface of the work piece. When a tool such as Hai is held in a hand-held or hand-guided machine tool, It is often difficult and time-consuming to achieve a certain quality during the processing of the surface of the work piece. "Hands are used to process a substantially flat surface (such as a plate or a metal sheet). It is often difficult for a machine tool to apply a substantially mutually determined force to guide the contact area of the machining surface of the tool to provide a completely uniform cutting of the work piece respectively. The higher the quality and accuracy of the surface to be processed, the higher the requirements for the guidance tool The slight swing of the hand of the machine is more likely to cause inaccuracies. In order to rule out the inaccuracy of the surface cutting of the work piece, sometimes the subsequent processing requires a lot of time ', which again wastes time and may also have to increase costs. If inaccuracy If it is too large, a damaged place will greatly reduce the value of the work piece. In addition, when the internal cylindrical grinding inside the cylindrical surface, such as the wrong hole _ -4- The dimensions of this record ίΐ 用 巾 国 g | 家 骑 （GNS ) (21Qx 297)

Invention Explanation (3) '~~ needed afterwards Processing is largely avoided, so that the surface of the work piece can be processed significantly faster and more economically. Β Because of the cylindrical embodiment of the tool, the tool of the present invention can be used according to the specific size of the tool body. Simple fit for flat, cylindrical, curved, and / or curved surfaces. Surprisingly, 'compared to grinding or polishing equipment, it can be found that the dust particles formed by the cutters of the present invention are essentially Less. Generally, the shavings remain essentially on the surface of the tool, or deposited there, without being moved to the surrounding environment by centrifugation. In a preferred embodiment of the tool of the present invention, an external crown The body is held on a hub 'which is preferably held by a spoke-shaped or disc-shaped connection device' so that the edge region of the crown-shaped body is cantilevered in the axial direction. The connecting device can ensure that the predetermined diameter of the crown is maintained, so that the force distance transmitted to the cutter is substantially regenerated on the crown, similar to the case of a wheel or a tire. "If an edge area is subject to a forced diameter, Directional deformation ... because of the rotatable coronal body, this radial deformation also occurs in the adjacent edge area, and the axially opposite edge area will deform in the opposite direction, causing the coronal body to surround the connecting device The area is inclined to further ensure that the contact area is substantially the width of the entire coronal body. If in a more advantageous embodiment, the structure of the connection device can be deformed in a way that can be automatically readjusted ', the cutter can withstand additional shear or torque. Because the tool can be held in a sleeve or radial direction separately or automatically adjusted and deformed, it can withstand slight vibration or transmit it to the area outside the contact area of the tool. -6- This paper size is applicable to the Chinese National Humble (CNS) A4 standard (21 Ox297) (please read the page on the back of the poem ii) and the line A ·?

Description of the invention (4 In a preferred development, 'If the envelope is surrounded by grooves or vertebrae, the rotation of the cutter to a better adhesion and self-centering of the processing medium extending around the envelope β Therefore, those skilled in the art know that the additional fixing device can be greatly eliminated. Moreover, one advantage is that an air cushion is formed between the tool and the extended processing medium to prevent the processing surface from rotating and cutting. There is unfavorable overheating during processing, otherwise it will cause defects on the surface of the workpiece and also cause excessive stress on the tool. For a material and cost saving embodiment of the tool of the present invention, a single sheet of plastic material The tool body (preferably manufactured by injection molding) has been found to be particularly practical and advantageous. Another aspect of the present invention relates to a tool, also known as a carrier, to hold an abrasive device on a back pad (especially a ring).

The disc 2 is particularly shown in FIG. 3, and is arranged in the middle of the hollow cylindrical coronal body 1 so that the rotational edge regions 1 a and 1 b of the coronal body are cantilevered and can be bent in the radial direction. . The disc 2 has a rather high rigidity in the direction control, and it is provided with through openings 7 which are arranged in a circle around the hub 3 to increase its axial reversibility. According to the desired flexibility of the disc 2 and the edge region [a, U], its thickness dimension can be determined in advance by the material, purpose, diameter and width of the blade. If a torque is transmitted to the tool by a machine tool (not shown in the middle), and it is held concentrically on the drive shaft 4 of the wheel 3, the final power is transmitted to the tool through the disc 2. Coronal body 1, wherein the radial rigidity of the disc 2 prevents compression of the coronal body 1, but elastic withdrawal is possible according to an embodiment of the present invention. Because the crown-like body 1 is rotatable, when the tool generates power, the edge regions 1 a and 1 b are held at a predetermined position, so the contact area (that is, the tool is in contact with the work surface 9 Area), extending over the entire width 8 of the coronal body 1. This action is detailed later. If the transmission shaft 4 shown in the third paragraph is rotated out by the tool axis X, for example, because the machine tool is slightly inclined in the direction of the arrow C, the force transmitted to the tool will be changed and the tool will be deformed , Especially the tilt of its envelope. The edge area la contacting the work piece surface 9 is deformed in the direction of the arrow VI. Because of the radial stability, (because of the disc 2) -9- _ _ This paper ruler is rich in national standard Chinese (CMS) A4 (210X297). -------- -Cui ------, 玎 ------ ^ (Please read the '¾. On the back of the page and then fill in the pages of the r.) Explanation (7) exists) 'and because there is a rotatable coronal body 1, the deformation in the V1 direction also occurs in the adjacent edge region, so the edge region lb axially opposite to the edge region la will bear the first class The amount of deformation V2 in the opposite direction is measured to ensure that there is a substantial deformation vi on one side of the work piece 9 on the side of the cutting material β and a forced reverse deformation V1 or V2 in the edge area, so that it surrounds the disc axis. γ-the area of the edge of the plane is inclined, and it is ensured that the contact area substantially further extends to the width 8 of the cushion body of the coronal body 1. “The restoring force due to the material of the rotating body and its specific structure during the deformation of the tool can further ensure that the coronal body is prevented from wrinkling. Moreover, when the transmission shaft 4 is rotated back to the tool axis X, the Make sure that the edge areas la and lb of the coronal body j can be deformed to return to their original or fixed state. Rotation of the drive shaft 4 in the opposite direction will cause corresponding and opposite deformations of these edge areas la and lb. When axial There is a compressive strain, for example, when the end of the tool hits a wall, a force will act on the tool in the direction of the arrow E. If you go one step further-the force D is transmitted to the tool in the opposite direction The compressive strain can be absorbed by the disc 2, which can be flexed in the axial direction, that is, the direction of the arrow V3 or V4, so that the tool does not immediately deflect or lock up. Because it is generally radial action The force will also exist, so the local tilt of the edge areas la and lb will occur at the same time, which may or may correspond to the deformation of these edge areas to further ensure that a contact surface can extend substantially to the tool.
