The polishing value of aggregate is the key index to determine whether a certain aggregate can be used in the anti-sliding wear layer of asphalt pavement. Paving the road surface with stones with high polishing value can improve the anti-skid ability of the road surface and ensure the safe driving of vehicles.
Polishing machine is a manual electric tool used to polish metal surfaces. Polishing machine is specially designed for treating the surfaces and pipes of metal products such as steel, aluminum and copper. Dozens of original factory accessories meet different needs, easily making snow patterns, brushed patterns, wavy patterns, matte surfaces and mirrors with different accuracy, quickly repairing deep scratches and slight scratches, and quickly polishing and polishing.
Extended data
Die polishing machine Die polishing machine adopts imported high-power devices, and the power is 30% higher than that of similar products. Microcomputer control resonance frequency automatic search and locking function; Numerical control nine-segment vibration size and discharge gap tracking adaptation function.
Scope of application: plastic polishing of complex cavities, narrow grooves and blind holes of various molds (including cemented carbide molds) from rough surface to mirror surface. Can polish all kinds of metals, glass, jade, agate and so on.
The speed of the turntable can be appropriately increased during fine polishing, and the polishing time is appropriate to throw away the damaged layer after rough polishing. After fine polishing, the ground surface is as bright as a mirror, and no scratches can be seen under the bright field of vision of the microscope, but wear marks can still be seen under the condition of phase difference illumination.
The polishing quality of grinding machine seriously affects the microstructure of samples, which has gradually attracted the attention of relevant experts. A lot of research work has been done on the performance of grinding machines at home and abroad, from manual operation to various semi-automatic and full-automatic grinding machines, and many new models and new generations of surface grinding machines have been developed.
