The knife edge (66) cannot be used to protect the film (75), and the protective film chip heat method is smoothly discharged, which causes the force of pulling the protective film (75), and under the condition that the protective film (7)) is not strongly adhered, It is easy to shape the shape of the money, and even more so that when the sheet (7G) is formed into the through hole, the protective film (75) on the upper and lower surfaces will have a burr 'and it is difficult to remove the burr.' It will damage the appearance of the board when it is shipped, and it can also make the protective film (75) peel off further and lose its protection. Through the above description, it is not difficult to understand that the design of the existing plate drilling and milling tools has not been perfected. Therefore, when the high-speed machining is performed, the pulling stress generated is likely to cause surface entrapment due to stress, thereby destroying the entire There are inconveniences and problems in the subsequent processing of the sheet caused by the problem of "easy pulling protective film" and "forming burrs, etc.", so it is necessary for A n ^ ^ a = this. The creator is facing the problems faced by existing drilling and milling tools. The second day sample A: the demand for the double-layer interface plastic plate user to use deep = wood two f hunting for many years engaged in the development of high-speed machinery plus I industry: unsolved, after long-term efforts research and development , "Export - can effectively remove the soft protective film, drill, and first tool structure of the double-layer interface board, so as to improve the efficiency and quality of the high-speed cutting processing of the double-lumen interface board. At the same time, the interface is 6 25 M297802 [New content] Therefore, this creation mainly provides a plate-shaped drill that can effectively remove the soft protective film covered by the material such as the Japanese comfort and can simultaneously trim the burrs generated by the high-speed cutting process. The milling cutter structure can maintain the integrity of the protective film during the processing of the sheet, further improve the processing efficiency, and at the same time improve the quality and appearance of the PMMA and other panels. ' '' This creation is mainly through the following technical means, the realization of the body, the purpose and effectiveness of the work · · The drilling and milling cutter has a - handle ^ ^; blade see ^ and 2 # appearance is flat, The shank is round. The blade portion is covered by the upper and the ice: the chamfering section of the 5I downward bundle and the cutting section of the smaller diameter, the blade section is arranged by the ί: into the chip chute with two equidistance settings, and the blade edge advances - Steps are made into a number of knives with a corresponding number of 30%, and the back faces of the bottom edges of the respective knives are respectively formed with a slightly rearward 1st 1=2; the knives are formed at the joints of the cutting section and the chamfering section. There is a dent-shaped ft itt to avoid the occurrence of pulling stress:: When it is ^, the protective film can be quickly removed, and the edge of the sheet can be used to effectively trim the protective film of the protective film, and the step-by-step can be improved. Explain that the following can be a better example. The following is only to explain the creation of the creation of a more detailed understanding, but in any form of this creation of the creation of the (four) embodiment, not intended to be made under God Any form is that any decoration or double in this creation should still belong to this creative intention. 15 25 M297802 Protection of the transformation [Implementation] This creation is dedicated to acrylic plates, PMMA plates or composites. Plastic plate:, such as the plate-like drilling and milling cutter of PE protective film, such as the third and fourth The figure shows: 'Hai Drilling and Milling Cutter has a shank part (〇) for the rotating shaft of the high-speed cutting machine tool and a blade part (2〇) for high-speed cutting; and the detailed composition of the structure of the creation is For example, in the third, fourth and fifth figures, the blade portion (5) has a chamfering section [-] from the top to the bottom, and a smaller diameter cutting section (22), the outer edge of the blade (20). At least two equally spaced chip chutes (23) are formed for cutting chip removal, and = the blade portion (20) advances to form a corresponding number of rotary knives (25) by using the aligning grooves (23) In this creation, two knives (25) are taken as an example. The end faces of the knives are formed with a slanted upwardly facing end face, and the surface of the blade (26) and the horizontal line extending from the axis are formed. The angle of 15 degrees, and then each knife (25) is formed on the back side of the corresponding cutting section (2) "chamfering section (21) with a slight backward tilting first, face η (27) (28), -, the second rear bevel (27) (28) and the drill = knife axis form an angle of -5 degrees to 9 degrees to enhance the sharpness and structural strength of the blade (25) end = mouth (10), and the system 25) At the joint of the cutting and chamfering (21) and forming a concave-shaped arc ^ (29) / the curved chamfer (29) can be used to soften the surface of the sheet (30) The protective film (35) performs the processing of the edge consumption; thereby, the gift & avoids the stress of the plate-shaped drill sharp knife which is used to pull the protective film due to the shear stress, and at the same time can be used for trimming the burr. In practical terms, as shown in Figures 6A and 6B, M297802 shows that each blade (25) of the slab-shaped drilling and milling cutter has a face edge (26) that is inclined upward toward the axis, so that A sharp-edged sharp edge is formed adjacent to the outer edge, so that when the cutting process is performed, the cutting edge of the end face edge (26) can be quickly contacted and effectively cut on the surface of the plate (30). The protective film (35) avoids wrinkles caused by pulling the protective film (35). Further, when the drilling and milling cutter penetrates the plate (30), the cutting edge of the end face edge (26) can still cut the lower surface first. Protective film (35), and the operator can further utilize the curved chamfer (29) of each blade (25) to PMMA Plate (30) of the surface protective film (35) doing fine trimming its edges, in addition to effectively lifting plate 9 (30) outside of the processing efficiency, and enhance their appearance and shipping quality. Therefore, it can be understood that this creation is a novel creation with excellent creativity, and has many functions and enhancements, and the same or similar product creation or public use is not seen in the same technical field, and the improvement of high-speed cutting processing effect is obtained. Therefore, this creation has met the requirements of the "newness" and "progressiveness" of the new patents, and is to apply for a new type of patent in accordance with the law.
