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
