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 … Read more

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 Main types of rolling bearing

A rolling bearing is a precision mechanical component that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. The rolling bearing is generally composed of an inner ring, an outer ring, a rolling body, and a cage. The inner ring is matched with the shaft and rotates together with the shaft; the outer ring acts to cooperate with the bearing seat to support the rolling body; The rolling element is evenly distributed between the inner ring and the outer ring, and its shape and quantity directly affect the service performance … Read more

What is Cast Iron?

For most guys working in the industry of metal machining, Cast iron must be a kind of familiar material. What is cast iron? First of all, it’s a sort of ferro-carbon alloy that contains more than 2.11% of carbon and small amounts of Si, Mn, S, and P. The mechanical properties of cast iron are lower than that of cast steel. But it has excellent castability, shock absorption, wear resistance and cutting machinability. The production process is simple and the cost is low. It is one of the most commonly used metal materials in engineering. Table of Contents Classification of … Read more

8 Common Microstructures of Metal and Alloy

Modern materials can be divided into four categories: metals, polymers, ceramics and composite materials. Despite the rapid development of macromolecule materials, steel is still the most widely used and most important material in the current engineering technology. What factors determine the dominant position of steel materials? Now let’s introduce it in detail. Iron and steel are extracted from iron ore, rich in sources and low in price. Iron and steel, also known as iron-carbon alloy, is an alloy composed of iron (Fe) and carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other small elements (Cr, V, etc.). … Read more

History And Development Of Tungsten Carbide Rolls

Continuously plastically deformed main working parts and tools on the rolling mill. The roller consists of a roller body, a roll neck and a shaft head. The roll body is the middle part of the roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roll neck is mounted in the bearing and the rolling force is transmitted to the frame via the bearing housing and the pressing device. The shaft end of the transmission end is connected with the gear seat through the connecting shaft, and transmits the rotational torque of the … Read more
