Electric processing machine tools: electric spark strengthening machine
Electric spark strengthening machine
Electric spark strengthening is a process of Microstructural and hardness modification of surface layer to improve fatigue, corrosion and wear resistance of metallic components; and even to modify surface properties. The strengthening is achieved by subjecting......
forging hammer
Hammers have been used by people for hundreds of years. Their uses have changed over time, but they still remain a useful tool in many areas.
The modern hammer is composed of a head and handle. The head can be made of a variety of materials including metal such as steel, titanium or aluminum, and......

Roller Bearings Installation and Common Issues
Roller bearings are one of the most common components of the mechanical sector. They are commonly installed in the powertrain, agricultural, and industrial machinery, as well as in aircraft, medical, and naval equipment. Roller bearings are genera......
Analysis of common faults and causes of rolling bearings (2)
Troubleshooting of Rolling Bearings (2)
1. Brinelling and Chattering
Brinellmarking or chatter is caused by impact that occurs when the bearings are installed. Some possible causes of brinelling include improper installation, electric shock, and high frequency vibration. The result is an indenta......
Common terms and definitions of rolling bearings V. Dimensions associated with tolerances
1. Tolerance: refers to the maximum limit of allowable departure of a part from its nominal size. The tolerance is sometimes expressed as a plus and minus value, such as +0.005/-0.002. This would mean the maximum departure from the nominal size for that part would be +0.005 and the minimum would b......
Preload of rolling bearings
Rolling Bearings Preload
The preload of rolling bearings is the tension applied to the bearing to prevent the outer ring of the bearing from rising when the bearing is in operation.
Preload is applied to the bearing in order to obtain the specified operational characteristics. It makes it easier......
Mechanical Engineering Materials: Casting Performance Tests
Introduction
Mechanical engineering materials play a vital role in today’s manufacturing environments, enabling processes such as casting, machining and fabrication to be undertaken. Casting materials form the basis of all these processes, where molten material (metal or plastics) are poured in......
