Application Advantages of CBN and PCD Tools in Automobile Industry

Currently, advanced foreign countries have put CBN and PCD tools into use on a large scale, which is inseparable from the rapid development of foreign high-speed CNC machine tools in the past 20 years. Especially in the automotive industry, foreign CBN and PCD tools have accounted for more than 30% of the tool market share. CBN and PCD tools are particularly suitable for applications on CNC automatic machining lines such as the automotive industry due to their excellent properties such as high hardness, high wear resistance, good thermal conductivity, and low friction coefficient.

How to distinguish left and right rotation of milling cutters

Milling cutters are the most important tools for CNC machine tools, and there are many types of milling cutters that we use daily, while end milling cutters are the most common. End milling cutters can be divided into two categories: left-handed milling cutters and right-handed milling cutters. Do you still have no concept of left-handed and right-handed milling cutters? To determine whether the milling cutter is left-handed or right-handed, we can use the following methods. Place the cutting edge of the milling cutter vertically upward. If the rising direction of the cutting edge slot is low from the left to high from the right, that is, from the left to the right, it is a right-handed milling cutter. We can clench our fists and extend our thumbs. The rising direction of the cutting edge slot is consistent with the right thumb, which is a right-handed milling cutter. Otherwise, it is a left-handed milling cutter, that is, if the cutting edge slot is from the right, it is a right-handed milling cutter

Selection of Gear Cutters for Hot Finishing

With the continuous innovation of modern industrial technology, the requirements for the quality and performance of parts are becoming increasingly strict. As an important component of modern mechanical transmission, gear processing requires increasingly high requirements for strength, toughness, and fatigue resistance. In order to obtain higher hardness, wear resistance, and fatigue resistance during the use of gears, heat treatment processes are often used to improve the performance of gear parts during processing. Generally, processing can be completed through processes such as blanking, forging, normalizing, machining, carburizing, quenching, rough machining, and grinding. 1、 Difficulties in gear processing 1. Generally, 20CrM is used for gears

What properties should the milling cutter material have?

During cutting, due to deformation and friction, the milling cutter bears great pressure and high temperature. The requirements that should be met as a milling cutter material are: 1. High hardness and wear resistance, that is, harder and more resistant to wear than the workpiece material; With high wear resistance, the tool does not wear, extending its service life. 2. Sufficient strength and toughness to withstand the impact and vibration during cutting, and avoid edge collapse and breakage; During the cutting process, the milling cutter must withstand a large impact force, so the material of the milling cutter must have a high strength, otherwise it is prone to fracture and damage. 3. High heat resistance (thermal stability), that is, it can maintain hardness and resistance to high temperatures

What are the types of cutting tools in machining? How to select a tool?

Cutting tools are very important in the machining process, and are directly related to the processing quality and accuracy. Today, with the rapid development of the processing and manufacturing industry, various new materials and processes are emerging in endlessly, and the materials and processes of cutting tools are also constantly changing and updating. What are the types of cutting tools in machining? 1. According to the classification of cutting tool materials, high-speed steel tools have high bending strength and impact toughness, and good processability. Carbide: Chemical vapor deposition is used to coat hard layers of titanium carbide, titanium nitride, aluminum oxide, or composite hard layers, resulting in low tool wear and long service life. 2. According to the cutting motion of the tool

How to choose a suitable mold processing tool?

In recent years, the development of the mold processing industry has tended to be high-end, with modern machining equipment and processes represented by machining centers placing high requirements on cutting tools. Selection of tool for mold processing In modern mold forming and manufacturing, due to the complex structure of the mold, high accuracy requirements, and significant differences in surface characteristics and materials at different parts, the mold milling tools used are also different. The mold processing process can be divided into rough machining, semi finishing, and finishing, sometimes even ultra finishing. Generally, indexable cutters are used for rough machining and semi finishing processes, while integral cutters are used for finishing processes. When the mold cavity is a complex solid
