Application Of Rockwell, Vickers And Leeb Hardness Tester And How To Choose

- Jan 20, 2019-

The Rockwell hardness tester can be divided into electric and manual according to the operation mode, and can be divided into pointer type and digital display type according to the display. Its functions are similar. Only the digital Rockwell hardness tester shows high accuracy (0.1 degrees). Rockwell hardness tester is used in: hardware processing, mold manufacturing, machining, raw material hardness measurement, heat treatment, metal hardness measurement, etc.; determination of Rockwell hardness of ferrous, non-ferrous and non-metallic materials, widely used in quenching, quenching and tempering Rockwell hardness measurement of heat-treated materials is mainly for the measurement of the hardness of some small products or after surface treatment. Vickers hardness tester is used in: hardware electronics, heat treatment, carbonization, surface nitriding gradient measurement, quench hardened layer, surface coating, stainless steel, copper copper strip, aluminum, steel strip, surface plating treatment and micro and thin Vickers hardness measurement of parts screws, precision parts, mold parts, ceramics, etc. The Leeb hardness tester is a portable new-generation hardness tester that is easy to carry and easy to operate. The Leeb hardness tester is used for: workpieces with very narrow test space such as mold cavity, machine tool guide rail, hardness test of automobile chassis; production line of bearings and other parts; failure analysis of pressure vessels, steam turbine generator sets and their equipment; direct test Large and heavy-duty specimens; quality control of heat-treated workpieces; installed mechanical or permanent assembly components; required formal raw records for test results; material differentiation of metal material warehouses; multiple measurement locations for large workpieces over a wide range Quick test.
