If there is no circular groove on the front of the end face of the four-blade tungsten steel milling cutter, you need to use the fillet of the grinding wheel or use a grinding wheel cutting machine to re-open the cross groove in the direction of the cross spiral groove of the milling cutter, with […]
No matter how many blades a tungsten steel milling cutter has, the end face of the blade must first be ground flat perpendicular to the axis. This is the key to ensuring that the highest point of the blade is on the same plane. The methods for grinding the blade end face and checking the […]
Ceramic cutting tools are characterized by high hardness, excellent wear resistance, good thermal stability, and chemical stability, and they do not easily adhere to metals. They hold a very important position in CNC machining and have become one of the main cutting tools for high-speed cutting and machining of difficult-to-process materials. Ceramic tools are widely […]
Matching of Cutting Tool Materials with Workpiece Mechanical, Physical, and Chemical Properties for Optimal Machining Performance 1. Mechanical Property Match Between Cutting Tools and Workpieces The matching problem regarding mechanical properties primarily involves the alignment of tool materials' strength, toughness, and hardness with those of workpiece materials. Different tool materials are suitable for machining different […]
Based on the type of machined surface, turning tools can be divided into external turning tools, internal turning tools, and end face turning tools. 1. External Turning Tools External turning tools are used for external turning, to machine the external cylindrical surface of a part, achieving the required size, geometric tolerance accuracy, and surface quality, […]
Correct selection of coating is the prerequisite for rational use of coated tools and full use of coating functions. The following is a three-point basis for the selection of PVD coatings. First of all, it still depends on the classification and hardness of the workpiece material. Generally speaking, TiN and TiCN are used for processing […]
The shanks of solid carbide end mills are primarily straight cylindrical shanks (see Figure A) and cylindrical shanks with a flat surface (commonly known as "side lock" or "side lock shank"). Straight Shank The shank of a straight shank milling cutter is a complete cylinder, therefore, in terms of the shank itself, this type of […]
Cermet is a heterogeneous composite material composed of a metal or alloy and one or several ceramic phases, of which the latter accounts for about 15% to 85% (volume). At the same time, at the preparation temperature, the metal and ceramic phases The solubility between them is quite small. The TiC(N)-based cemented carbide used to […]
Collet is a device for clamping cylindrical workpieces, mainly used in machining processes on machine tools. It is characterized by uniform clamping force, a wide range of clamping diameters, and the ability to adapt to workpieces of different diameters. Collet consists of a clamping barrel and a clamping ring. Its advantages are simple operation and […]
Thread mill is a tool used for milling threads and spiral grooves. In machining, it is widely used in automobile parts, aviation parts, electronic components and other fields. According to different structural forms, thread milling cutters can be divided into two types: single teeth and three teeth. The difference between single teeth and three teeth 1. Cutting efficiency The cutting […]
