High Quality internal grinding wheels factory
High Quality internal grinding wheels processing HRC35-HRC70 degree steel parts (20 chromium steel, 40 chromium steel, tool steel, die steel, bearing steel, alloy steel, structural steel, high-speed steel, ductile iron, heat-resistant steel, titanium alloy, 38 chromium molybdenum aluminum, special Structural steel, etc.)
Customized vitrified bond CBN internal grinding wheels and grinding heads for grinding small holes.
CBN internal grinding wheel produced by our factory can achieve a small diameter of 1.5 mm, and the wear resistance is very good, and there is no need to frequently trim the outer circle. Batch processing of small holes of parts can ensure the consistency of roundness, perpendicularity and diameter tolerance accuracy, high temperature resistance during the grinding operation, and no burns on the workpiece and the grinding wheel. Grease grinding fluid must be added during the grinding process To cool down and remove chips (tap water can not be added directly, tap water will carbonize the high-temperature grinding CBN raw materials), to avoid the large amount of metal scrap generated during the grinding process from squeezing the hole wall of the workpiece and blocking the pores on the surface of the cubic boron nitride grinding head .
During the use of the internal grinding wheel, the feed amount should not be too large, generally controlled within 0.01 mm, and the feed speed can be adjusted according to its own process. The effective use length of the grinding wheel should be calculated according to the length of the grinding hole. It should not be too long. Too long the grinding wheel will cause excessive grinding pressure, but internal grinding wheels will feel unusable. The higher the speed of the grinding machine, the better the grinding efficiency will be, and the grinding efficiency of the grinding wheel with too low speed will not be guaranteed. Moresuperhard will design and customize this type of super-hard CBN grinding wheel according to the customer’s grinding process and actual requirements
