In the process of developing the tool, we invested a lot of manpower and material resources to find better materials and the best shape to extend the service life of the tool. With the birth of new materials, the tool life has doubled, but the new material Costs and tooling costs are also growing slowly, not necessarily for manufacturers and consumers who use tools a lot. Professor Prof. Dr.-Ing. Tikal of the University of Kaiser, Germany, and Dr. Risse of the University of Aachen, Germany, after years of research and practice, recommended a new simple tool processing process: Dull. It doubles the life of the tool.
(1) Provide guarantee for the quality of tool processing:
Newly produced tools are generally required by manufacturers to ensure the sharpness of the tool front, but due to the different materials and processing techniques of the tool, the absolute sharpness is not achieved, generally less than 4mm. The same front of the same tool will also produce an error greater than 1mm. Such a tool produces a frontal boring during the first machining process, which reduces the quality of the work. In particular, coated tool openings are common and can sometimes result in damage to tools and workpieces. In addition, the machining error of the new tool and the old tool increases with the wear of the tool front, which reduces the consistency of the quality of the processed product. The blunt-processed tool can substantially avoid the above problems.
1. The blunt-processed tool will also shave the burrs and droplets generated during the tool production, smoothing and polishing the workpiece, making the tool more beautiful and increasing the surface hardness of the tool. The smoothness greatly improves the smoothness of the cutting.
2. Especially for the passivated tool before coating, the coating will be more uniform, which greatly reduces the risk of coating the mouth at the blade. Professor Dika has carried out a large number of research and experiments on rotary machining tools such as drills, taps and milling cutters, summarizing the feasibility of the blunt and the enormous economic benefits that can be brought from theory to practice.
(2) No wear degree, the blunt technology can double the life of the tool (3), the length of the workable workpiece can be improved, the operation is simple and flexible, and the tool processing processed by the blunt process is divided into physical processing mode, heat treatment mode and Chemical treatment. The most economical is the physical processing method, such as using the DF polishing machine produced by Otec of Germany for blunt. The DF polisher allows the tool to make a rotary motion in the abrasive to achieve the blunt requirements.
The advantage is that the workpiece is deburred and polished while being blunt, and the tool can be blunt and blunt according to the set processing time and steering procedure, plus different abrasives. .
(4) Improve the processing efficiency and reduce the processing cost. The blunt technology has been widely used in Germany. The German Mercedes-Benz Automobile Company has a machining center, which uses more than 80 kinds of drilling and milling tools. After the tool is processed for 100h, all the tools need to be updated; after using the blunt-cut tool, the machining time is extended to 240h. Increased processing efficiency and reduced processing costs.
