Tungsten Carbide Cutting Blades

Introduction

Tungsten carbide cutting blades are commonly known as cutting machine blades, also known as shearing machine blades, cutting feet. Because the shape is circular, it is also called a disc cutting knife, which is mainly used for cutting the lead legs of the electronic circuit board on the cutting machine.

The specifications of the cutting machine blade are mainly Φ250×Φ70×3.5 and Φ200×Φ70×3.5, which is also commonly known as 10 inch and 8 inch. Its main material is cemented carbide. The main component of cemented carbide is tungsten carbide, which is also called tungsten steel, so it is also called tungsten steel cutting machine blade. As a high hardness, high strength, wear and corrosion resistant material, cemented carbide is widely used in the cutting tool manufacturing industry. Due to the high brittleness of the cemented carbide, it is not possible to directly perform the cutting process, and it is difficult to form a whole-tool with a complicated shape. Therefore, the blades of different shapes are often formed and mounted on the cutter body or the mold body by welding, bonding, mechanical clamping or the like. use.

Development and Application

Along with the extensive development of the electronics industry, the market demand for printed circuit boards, the generation of cutting machine blades is also a development of cutting tools. There are two main forms of board production: one is solder feet with plug-ins, and the other is directly formed by patches. Due to the high-end production equipment required for the production of the patch form, the required investment is relatively high, and most of them still use the cutting machine blade cutting insert.

The soldering pins of the circuit board with plug-ins are also thick and soft, and the performance requirements of the cutting machine blades are different for different operation requirements. Of course, the cutting performance is also related to the cutting machine itself. Along with the continuous development of China's cemented carbide related materials, the market will have higher requirements for cutting machine blades to meet the objective needs of the development of the electronics industry.
