How are the grinding and cutting needs of high-performance carbide round bars met?

High-performance cemented carbide round bars are widely used in aerospace, automotive, and machinery manufacturing industries, and their grinding and cutting needs have been the focus of industry attention. To meet these demands, several factors need to be considered, including material hardness, cutting performance, and process requirements.

Firstly, grinding and cutting are common metalworking processes used to produce precision surfaces and specific shapes for workpieces. For high-performance cemented carbide materials, the grinding and cutting processes require the selection of suitable technologies and tools due to their high hardness and toughness characteristics.

Grinding removes material from the surface of a workpiece using the friction-damaging effect of abrasive grains to achieve machining accuracy and improve surface quality. For the grinding of high-performance carbide round bars, various grinding wheels can be used for precision grinding. Firstly, it is necessary to choose the grinding wheel suitable for the hardness of the material and the shape of the workpiece, such as diamond grinding wheels and vertical grinding wheels. Secondly, it is necessary to determine the grinding parameters according to the requirements of the grinding process, including cutting speed, feed speed and grinding depth. The selection of these parameters needs to be optimised according to the specific process and workpiece material to obtain the ideal grinding effect.

Cutting is the cutting or removal of material from a workpiece by a tool for the purpose of shape processing and size control. For cutting of high performance carbide round bars, tool selection, tool material, and machining parameters need to be considered. Tool selection should be matched to the shape of the workpiece, cutting requirements and machining accuracy. Common cutting tools include carbide tools, CBN tools and so on. These tools have high hardness and wear resistance and are suitable for cutting high hardness materials. At the same time, the cutting process needs to determine the appropriate cutting speed, feed rate and depth of cut and other machining parameters to improve the cutting effect and extend tool life.

In addition to the consideration of tool selection and machining parameters, the grinding and cutting of high-performance carbide round bars also need to consider the introduction of new machining technologies and process methods. For example, technologies such as superhard cutting tools, ultrasonic cutting, and EDM can be used for cutting and grinding of high-performance tungsten carbide round bars. These new technologies and processes are of great significance in improving machining accuracy, extending tool life and improving surface quality.

In addition, it is necessary to continuously improve and optimise the process of grinding and cutting by combining production practice and in-depth understanding of material properties. Through process improvement and technological innovation, the grinding and cutting efficiency of high-performance cemented carbide round bars can be improved, and energy consumption and cost can be reduced.

In summary, in order to meet the grinding and cutting needs of high-performance cemented carbide round bars, it is necessary to choose suitable tools and cutting parameters, learn from new processing technology and process methods, and combine with the actual production for continuous improvement and optimisation. Only by comprehensively considering the material properties and process requirements can we meet the needs of high-performance cemented carbide round bar grinding and cutting.
