How to choose the right segment of bush hammer roller ?
The surface of the stone polished by the bush hammer heads forms a rough surface such as lychee skin, which can make the stone as a floor tile play a non-slip role.
Bush hammer roller pins are divided into loose tissue and compact tissue. Loose tissue foreheads are suitable for flat surfaces, grinding processing with large contact surfaces and soft stone workpieces,for exemple 20S star type bush hammer roller. The tight tissue is suitable for fine grinding of workpieces with high surface finish requirements, such as grinding roller head with 99 segment.
The material of bush hammer heads is mainly cemented carbide as good. Its grain size determines the processing accuracy of the processed stone surface and the requirements for productivity, rough machining or semi-finishing with low hardness and ductility. High toughness of the material using coarse grit bush hammer head processing or medium grit bush hammer head processing, on the contrary finishing and superfinishing and high hardness, brittle performance of the material requires a fine grit grinding roller head.
