Common quality defects after heat treatment of bearing parts
1. Too Low Hardness
As with any kind of heat treatment process, one of the most common quality issues that can arise when heat treating a bearing part is too low hardness, usually caused by insufficient heat treatment time and temperature. If the bearing part is below the specified hardness, it wi......
Grinding burns and cracks
Grinding and Burning and Cracking
Grinding and burning are two very common actions that are performed when machining a variety of materials. While both of these actions involve the use of high levels of force and heat, they have very different effects on the finished product. This article will com......
Mechanism of Grinding Cracks and Prevention Measures
Content Introduction
Grinding cracks are common defects in grinding process, which are caused by improper cutting parameters or system misalignment. Generally, tool wear, improper cutting parameters and out-of-balance forces during grinding are mainly responsible for grinding crack occurrence. Wh......
Example of heat treatment: heat treatment of bearing parts (below)
Thermal treatment as a series of processes can increase the hardness of a material through a variety of methods such as hardening, tempering, and annealing. The main purpose of theses processes is to optimize the material to better fulfill its intended functions. For example, bearing type parts th......
Analysis and preventive measures of ring grinding burn
Analysis and Prevention Measures for Overlap Grinding Burn and Scores
Grinding burn is an important part of the actual grinding process and will most likely occur in high-speed cutting of workpiece. When the heat produced by the friction between the grinding wheel and the workpiece is not dissipa......
Bearing assembly
Introduction
Bearing assembly is an important step in the construction of rotating machines, tools, and other equipment. It begins with the selection of the bearings appropriate for the application and then follows through with mounting the bearings in their housings and securing them in place. T......
