Annulus of hard alloy roller is in carbonization tungsten the applied carbonization tungsten of steely industry hard alloy is compound the applied range of roller annulus is very wide, small profile of etc of wire, great ability, canal material, the production that waits like square steel, 6 angle iron, flat steel, angle iron can use this one technology, to rolling mill function rise to get favorable result. Carbonization tungsten the 10-20 that the life of make friends chamfer of compound roller annulus makes an appointment with hard alloy is common and cast-iron roller times, repair the 1/2-1/3 that grinding a quantity is cast-iron roller only every time, accordingly, compare with photograph of traditional and cast-iron roller, the total rolling quantity of compound roller annulus is hard alloy the 20-40 of common roller times. Hard alloy roller is in process of rolling of high speed wire, its sheet chamfer crosses steel to measure outclass cold hard cast-iron or high-speed steel roller. Milling of chamfer of crescent moon of annulus of hard alloy roller machines carbonization tungsten chamfer of crescent moon of hard alloy roller engraves carbonization tungsten when costal region is machined, use commonly use milling cutter of stone carving of CDW025 King Kong (call flying knife again, milling cutter coming back) . Common and tie-in: Lever of a burin coming back + milling cutter of chamfer of 2 crescent moon matchs for mark. Among them, solder milling cutter of crescent moon chamfer does 4.0-9.0mm commonly; 4.0mm makes milling cutter of chamfer of integral crescent moon commonly below. The material of the razor blade of chamfer of crescent moon of mill of bit material qualitative roller of chamfer of crescent moon of mill of annulus of hard alloy roller chooses carbonization tungsten commonly character thick granuality the PCD material of 25 micron is qualitative, CDW025 brand, have very tall wearability and point quality, apply to higher to requirement of cutting tool wearability treatment case, can use at machining aluminium alloy, tall silicon aluminium alloy, copper alloy, hard alloy, aggrandizement the material such as plastic, composite material, black lead is qualitative.
