Impact test
Impact Tests
An impact test is a type of accelerated stress test designed to determine a material’s toughness and its ability to absorb energy. It is a destructive test, meaning that it can cause permanent damage to the material being tested. Impact tests can be used to test elastomers, plastics......

Hardness conversion table and common sense
Brinnel Hardness Scale
Brinnel Hardness Scale is a widely used method for measuring the hardness of materials. It was named after an English inventor, Ernest Brinnel. This scale consists of a series of indentation tests that measure a material’s ability to resist deformation, or hardness. In the......
Use and Improvement of Imported Large Hydraulic Press
Introduction
The use and improvement of the large imported hydraulic machine can help improve production and save costs. Large imported hydraulic machinery can provide more powerful operation capability than domestic machines, and can work in a harsh environment to meet the needs of production a......
GB 10893-89 Specifications and tests for compressed air dryers
GB 10893-89 Air Compressor Dryers Specification and Test
Air compressor dryers are devices designed to remove moisture and other contaminants from air or gas. This standard applies to air compressor dryers with a nominal valve of 1 day. The maximum working pressure should not exceed 1.6 MPa and t......
GB4884.2-1995 pure helium
Hydrogen is a chemical element with the symbol H and atomic number 1. With an atomic weight of 1.008, it is the lightest element on the periodic table. Hydrogen is the most abundant chemical substance in the universe, making up 75% of normal matter by mass and almost all of the helium in the unive......
Feed Rate of Rough Boring of Carbide and Alloy High Speed Steel Boring Tool in Turning
Introduction
Cutting speed, feed rate and depth of cut (DOC) are the fundamentals of machining and play a crucial role in determining the production rate and cost of a machining process. In most cutting operations, when these factors are optimized, higher productivity and lower machining cost ca......
The relationship between feed rate and tool nose radius roughness in turning
Introduction
This study examines the relationship between the feed rate and the roughness of the tool tip in turning operations. Turning operations involve using a specially-designed cutting tool and a power-driven unit to move the tool along the surface of a rotating workpiece to shape it into a......
