Recommended materials for reference in the selection of CNC milling cutters
Cutting technology is an integral part and key technology of the advanced equipment manufacturing industry. The revitalization and development of my country's equipment manufacturing industry must give full play to the role of cutting technology and pay attention to the development of cutting technology. The emergence of CNC milling cutters provides a very good opportunity. The following is a brief introduction and analysis of various types of CNC milling cutters:
1. The material milling cutter of the cutting part of the milling cutter is the cutter used in cutting the workpiece on the milling machine. Commonly used CNC milling cutters cut part of the materials usually divided into two categories, one is high-speed tool steel (referred to as high-speed steel), and the other is cemented carbide. High-speed steel uses tungsten, chromium, vanadium, molybdenum, and cobalt as the main elements. Cemented carbide is made of high-hardness metal carbides and metal binders through powder metallurgy. High-speed steel has many advantages, such as high bending strength and good toughness, the hardness after heat treatment can reach 63~70HRC, and the thermosetting temperature can reach 550°C~600°C, which has good cutting performance. It can be cast and hot-rolled, using this material can be used to make a variety of complex shape cutters, generally complex shape milling cutters are made of high speed steel. Cemented carbide is superior to high-speed steel in terms of hardness, wear resistance and heat resistance. The hardness of cemented carbide is very high, it can reach 74~82HRC at room temperature, and the thermal hardening temperature can reach 800°C~1000°C. The disadvantages of cemented carbide are low bending strength and brittleness, so it is only suitable for manufacturing tools with simple shapes.
2. The types and applications of CNC milling cutters are classified according to the purpose and shape of the milling cutter. There are milling cutters for milling planes, milling cutters for milling right-angle grooves, milling cutters for milling special grooves, and milling cutters for special-shaped surfaces. Knife and so on.
3. The names of various parts of the CNC milling cutter and the main angle milling cutters are similar to the cutters used by the lathe. Therefore, the milling cutter can be regarded as several cutters evenly distributed on a circular body, each Milling cutters are composed of body, groove angle, cutting edge, rake face and flank face. During milling, the cutting edge cuts into the metal layer of the workpiece to form a cutting. The surface from the cutting teeth is the rake surface; the surface opposite to the machined surface is called the flank surface; the intersection of the rake surface and the flank surface The line is called the cutting edge.
Of course, when you want to choose one or several CNC milling cutters specifically and correctly, it is not enough to just look at the above overview. You need to refer to various materials to fully understand all types of CNC milling cutters before you can make the correct choice. Everyone is a professional book-full diagrams on the selection of CNC milling cutters.
This book is mainly aimed at modern CNC milling cutters, combined with the conditions of the processing site, from the perspective of the operator or the user, in the form of illustrations and examples, it introduces the selection and application technology of CNC milling cutters in detail, and strives to be close to the actual production. The main content includes: the concept of milling, common milling forms and corresponding types of milling cutters, the selection and application of face milling cutters, end milling cutters, slot milling cutters, profiling milling cutters, and tool selection examples. From this book, you can learn not only the selection and use of CNC milling cutters, but also the methods to solve common problems in CNC milling.
This book can be used as a self-study and short-term training book for CNC milling machining center operators and ordinary milling workers to CNC milling. It can also be used as a textbook or reference book for the application of CNC technology in colleges and universities. This book is mainly aimed at modern CNC milling cutters, combined with the conditions of the processing site, from the perspective of the operator or the user, in the form of illustrations and examples, it introduces the selection and application technology of CNC milling cutters in detail, and strives to be close to the actual production.
All major user manufacturers can find this book in bookstores. It is a very worthy reference book. You can buy it yourself if you need it. If you don’t understand, you can also find our professional customer service to serve you sincerely.
