[Prior Art] According to the current technology, the technology is constantly evolving, making it possible for both the mechanical industry and the electronics industry to have their own technology. For example, the printed circuit board (Printed Circuit B oard) , _P CB ) The indispensable material of the technology industry, and a cutting tool 'for example: milling cutter, drill bit and ore piece, etc., is a machining JL with frequent use and no stranger in the mechanical processing industry; fine, the milling cutter It is also a necessary cutting aid for the production of the printed circuit board (PCB). Therefore, the technology of the machine and electronics industry cannot be separated. In addition, the milling cutters generally used in the manufacture of the printed circuit board (pc B) are made of a high-hardness tungsten carbide (Wc) steel material because the milling cutter is in contact with the workpiece (eg · The printed circuit board (pc B ) 5 1288040 ) implements a plunging hole, and the machine and the workpiece are in a high-temperature friction environment at a high speed operation in response to various required operations, and the milling is relatively caused. The part of the knife that the knife is in contact with the workpiece is subject to wear, even breakage, and since the knife usually has a certain length specification limit, when the knife portion of the sharp knife is subjected to wear and breakage, thereby causing the length thereof to change, First, the user's practice is to discard the whole cutter as a scrap and re-order it – a new cutter. Under the realistic conditions of limited resources of i-ball, it will also make carbonization and raw materials become less and less, and the secret recipes only meet the concept of environmental protection and environmental protection. At the same time, the secret causes carbonization of Hegang original 2 The cost of transmission and delivery is not high, and it is relatively expensive for the manufacturers of milling cutters. Because of the high cost of carbon-like materials, the cost of manufacturing can not be reduced. It is less economical and market-oriented. Observing power, therefore, this is the problem faced by the current milling cutter industry. Therefore, in order to solve the aforementioned problems, a milling cutter that has been used has been introduced on the market, and the end portion of the cutter has been cut and polished to form a blade portion having a screw-like shape. The end faces of the knives on one end of the blade are welded and fixed to each other to form a new sharp knife. Hawthorn's new milling cutters, which are integrated with each other, can solve the problem that steel materials are expensive and meet the concept of recycling and reuse of 1288040 and environmental protection, but still have the following shortcomings: They are integrally joined to each other by butt welding, so that the outer edges of the welded joints that are butted to each other will protrude from the outer edge, and therefore must be removed, which will increase the processing procedure. 2. Since the systems are connected to each other, it is necessary to consider the accuracy of the butt joints. In addition to the need to process and remove the protruding solder, it is necessary to apply concentricity at the same time. • Grinding processing 'both are easy to have concentric machining precision considerations, if There are still deviations that will affect the stability of the rotation, which in turn causes instability of the rotational offset sway at the cutting end. 3. In terms of mechanics, 'because their systems are butted together, it is easy to residual stress at the butt joints'. This is inevitable for the reaction force of the longitudinal cutting of the milling cutter, and even has a large vibration effect, causing troubles in the operation. . Based on this, the (4) people in this case are in the market of Qianma-Merlin, and in the market with constant changes, only the constant inventing of unique and mineral-effect printing is obvious (4) often; How to get rid of the fiercely competitive market without being eliminated, that is, the purpose of this case (4). SUMMARY OF THE INVENTION In the above description, it is known that the regenerative sharp knife currently manufactured on the market "solves the concept that the carbon steel material is expensive, and conforms to the concept of resource Z and environmental protection, but still has an increased treatment. The shortcomings of the operation process, the precise consideration of concentricity and the residual stress; because of the fact that 7 1288040, the inventor’s troubles have been difficult to produce for many years, but after a long period of hard work, the experimental experiment The kind of "reproduction cutting tool system can be described as a hybrid structure", which is helpful to the public. The main purpose of this side is to effectively solve the shortcomings of the processing of regenerative tools (10) and the accuracy of docking (four) degrees. At the same time, it provides stability, reduces production costs, and meets resource recycling. Use and Meide's regeneration cuts (eg milling cutters) to enhance its competitiveness in the market.
