What is the hardness?
a Japanese Corporation Mitutoyo offers a wide variety of tools for determining the hardness of any materials, from rubber to metals. Each mechanism is characterized by versatility, high quality and technical equipment, because the manufacturer in the manufacture used advanced CAD technology. And a long trouble-free operation and a long service life is achieved through the use of quality materials.
Hardness is a tool with which to determine the hardness of parts, without violating its integrity. These devices are widely used in research institutes, in the automotive industry, as well as during incoming inspection of spare parts.
How are the dimensions
these tools are of two types: stationary and portable. The choice of Durometer (this is the second name of hardness) depends on the structure of matter and its properties, as well as the size and configuration of the inspected product. The scale on which the hardness test, also vary. Typically the mechanical check is for scales:
- Shor - for soft products. During the measurement of hardness on this scale calculates the penetration depth in matter of a rod of steel.
- Rockwell - for products of average hardness. In this method, by means of the microscope calculate the depth and diameter of indention, which is embedded in matter.
- Vickers for superhard products. Under this method, the matter introducing the diamond tetrahedral pyramid. Hardness is the division of the load on the surface area.
in Addition to the mechanical method of determining hardness, there are others: dynamic and ultrasonic. During the dynamic test measures the speed of the indenter after contact with the tested product. Ultrasound this indicator is determined by the change in the oscillation frequency of the indenter, provided that it is implemented to check the matter.
what are the benefits of hardness testers Mitutoyo?
Sodeistvie in the production of advanced technologies allowed the company to create high-quality measuring tool. At its manufacture were used only high quality materials that provide adequate resistance to impact, moisture and dust.
it Should be noted that the device is complemented by components that enhance its performance: with video cameras, units for automatic positioning and focusing. The tool is also equipped with professional software. All this allows to measure the toughness of details in just 0.3 seconds.
