How do Grinding Parameters Impact on Tungsten Carbide Products?

Hey everybody, a new material weekly on surface grinding of ultra-fine cemented carbides. Reading this probably cost you about 15 minutes Abstract of this article: The grinding experiment of superfine cemented carbide was carried out on a plane grinder with diamond grinding wheel. The grinding surface morphology was observed by scanning electron microscopy and the surface roughness was measured by surface roughness tester. The influence of grinding parameters on the surface roughness of ultra-fine cemented carbide grinding was analyzed. The results show that the grinding surface roughness of superfine cemented carbide increases with the increase of grinding wheel size at the same … Lee mas

What Should You Know about Brazing of Carbide Brazed Tools

The main products that need to be used for brazing carbide brazed tools are the bimetallic structure of cutting tools, measuring tools, dies and excavation tools. The characteristic of this bimetallic structure is that its cutting parts are cemented carbide, and the matrix is carbon steel or low alloy steel, usually medium carbon steel. A bimetallic structure can cushion the tremendous stress acting on this kind of workpiece, especially under compressive bending, impact or alternating loads. Most of the carbide brazed tools are welded to the medium carbon steel or low alloy steel matrix. The brazing process is closely related … Lee mas

5 Main Materials Applied in Cold Stamping Process

Stamping dies work under the impact, vibration, friction, high pressure, tension, bending and torsion loads, and even at higher temperatures (such as cold extrusion). The working conditions are complex and easy to be worn, fatigued, fractured, deformed and other phenomena. Therefore, the requirement for the material of the working parts of the die is higher than that of the ordinary parts. Due to the different working conditions of various stamping dies, the requirements for the materials of working parts of the dies are also different.

10 principales tipos de rodamientos

Un rodamiento es un componente mecánico de precisión que cambia la fricción de deslizamiento entre el eje en movimiento y el asiento del eje en fricción de rodadura, lo que reduce la pérdida de fricción. El rodamiento está generalmente compuesto por un anillo interior, un anillo exterior, un cuerpo rodante y una jaula. El anillo interior se hace coincidir con el eje y gira junto con el eje; el anillo exterior actúa para cooperar con el asiento del cojinete para soportar el cuerpo rodante; El elemento rodante se distribuye uniformemente entre el anillo interior y el anillo exterior, y su forma y cantidad afectan directamente el rendimiento del servicio ...

¿Qué es el hierro fundido?

Para la mayoría de los tipos que trabajan en la industria del mecanizado de metales, el hierro fundido debe ser un tipo de material familiar. ¿Qué es el hierro fundido? En primer lugar, es una especie de aleación de ferro-carbono que contiene más del 2,11% de carbono y pequeñas cantidades de Si, Mn, S y P. Las propiedades mecánicas del hierro fundido son menores que las del acero fundido. Pero tiene una excelente capacidad de fundición, absorción de impactos, resistencia al desgaste y maquinabilidad de corte. El proceso de producción es simple y el costo es bajo. Es uno de los materiales metálicos más utilizados en ingeniería. Clasificación de tabla de contenidos de ... Lee mas
