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 … Ler mais…

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 … Ler mais…

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. Table of Contents Requirements for various stamping molds1. for blanking dies2. for Drawing Die Materials3. for … Ler mais…

10 tipos principais de rolamento

Um rolamento é um componente mecânico de precisão que altera a fricção de deslizamento entre o eixo de rolamento e o assento do eixo para o atrito de rolamento, reduzindo assim a perda por atrito. O rolamento geralmente é composto de um anel interno, um anel externo, um corpo rolante e uma gaiola. O anel interno é combinado com o eixo e gira junto com o eixo; o anel externo atua para cooperar com o assento do rolamento para suportar o corpo rolante; O elemento rolante é distribuído uniformemente entre o anel interno e o anel externo, e sua forma e quantidade afetam diretamente o desempenho do serviço… Ler mais…

O que é o ferro fundido?

Para a maioria dos caras que trabalham na indústria de usinagem de metal, o ferro fundido deve ser uma espécie de material familiar. O que é ferro fundido? Em primeiro lugar, é uma espécie de liga de ferro-carbono que contém mais de 2,11% de carbono e pequenas quantidades de Si, Mn, S e P. As propriedades mecânicas do ferro fundido são inferiores às do aço fundido. Mas tem excelente capacidade de fundição, absorção de choque, resistência ao desgaste e usinabilidade de corte. O processo de produção é simples e o custo é baixo. É um dos materiais metálicos mais usados em engenharia. Índice Classificação de… Ler mais…
