Tungsten carbide internal thread machining

As a wear-resistant and corrosion-resistant metal material, cemented carbide is the first choice for high-end wear-resistant parts. Especially for some delicate and small core working parts, the wear resistance of tungsten carbide is better than that of any other material. However, due to the high hardness and high wear resistance of cemented carbide materials, the non-standard customization and processing of cemented carbide are relatively cumbersome and troublesome, the processing of cemented carbide wear-resistant parts, especially the precision machining of threaded cemented carbide parts, has very high requirements for equipment and technology. Zhuzhou Chuangrui Cemented Carbide Co., Ltd. will introduce to you the relevant knowledge of cemented carbide internal thread processing.

In machining, the thread is also called a screw, which is cut with a tool or grinding wheel on a cylindrical shaft, and the workpiece rotates at this time, the tool moves a certain distance along the workpiece axial, and the traces cut out by the tool on the workpiece are threads. The thread formed on the outer surface is called the external thread, the thread formed on the surface of the inner hole is called the internal thread, and the basis of the thread is the spiral on the surface of the circular shaft. For super hard materials such as cemented carbide, it is difficult to guarantee the size for the traditional threading process,which requires the start of the operation from the production of cemented carbide blank material to the completion of precision machining.

Zhuzhou Chuangrui Cemented Carbide Co., Ltd. produces customized internal threaded cemented carbide parts using solid carbide material semi-processed blank pressing and sintering molding, cemented carbide internal thread processing is mainly brought out through the blank, the internal thread is directly formed and processed in the blank semi-processing production process, and then the surface is finished by precision processing equipment, the size is accurately controlled and processed into the precision alloy parts required by the customer's drawings. The deep processing system is the basis of precision machining of cemented carbide, especially the processing of internal threads and other technically difficult alloy non-standard parts, the cemented carbide produced by powder metallurgy production process, as a typical representative of superhard metal, is the best choice of wear-resistant parts because of its high hardness, high strength and good toughness.

Precision machining focuses on every detail of the production process of cemented carbide products, and for cemented carbide internal thread processing, it is necessary to have advanced technology and complete equipment to meet the requirements of various types of internal thread products. The requirements for the production and processing of precision parts similar to cemented carbide wear-resistant parts, which requires strong technical support and rich experience in the cemented carbide deep processing system with advanced production equipment to achieve μ-level precision tolerance requirements.
