In this article we will discuss the differences between the drills are made of different material: HSS high-speed steel and drills from carbide material. Consider what materials can be processed these drills, what are the subtleties of sharpening, the cutting data and also compare the quality of the surface subjected to treatment.
the First samples of the composite materials appeared in the times of Ancient Egypt. Most often, they consisted of 2-3 components. Each component had properties that were different from the other. A well-known material which has the end result of adding the hair in resin. More similar to modern analogs is Bulat, which is the …. Read More
Wagon and locomotive depots for the grinding of the tread surface of wheel pairs and processing of the surfaces of the side frames and bolsters used carbide inserts RPAX 3010MO, 2710МО, RNX 1212MO, LMNX and BDMX. The volume of hard alloy used for these purposes, average 30 tons per year. The cost of the plates …. Read More
the processing of metals has shown that one effective way of increasing performance is the use of new tool materials. the Coating of the cutting tool must increase: hardness, in order for a long time to save cutting properties of the tool; — ability to maintain necessary hardness when cutting Mella; — tool. currently, approximately ….
