Grinding wheel improving grinding cooling and grinding quality

Abstract

The invention discloses a grinding wheel improving grinding cooling and grinding quality. The thickness of the grinding wheel is larger than or equal to 20 mm. The two end faces of the grinding wheelare each provided with an annular groove. When the diameter of the grinding wheel is larger than 200 mm and smaller than or equal to 500 mm, is larger than 500 mm and smaller than or equal to 600 mm,and is larger than 600 mm, the thickness of the annular grooves is 5-10 mm, 15-20 mm and 25-40 mm correspondingly, and the depth of the annular grooves is 1-2 mm, 2-3 mm and 2-3 mm correspondingly. The circumference between the annular groove in each end face of the grinding wheel and the outer circle surface is provided with a plurality of evenly distributed and eccentric straight grooves which achieving communication of the corresponding annular groove and the outer circle surface, the width of the straight grooves is 2-4 mm, and the depth of the straight grooves is the same as that of the annular grooves. On the end faces of the grinding wheel, the included angle alpha between the connection line of the intersection point of the center axis of the straight grooves and the outside grooveedges of the annular grooves and the center of the grinding wheel, and the center axis of the straight grooves is 10-20 degrees, when the diameter of the grinding wheel is larger than 200 mm and smaller than or equal to 500 mm, is larger than 500 mm and smaller than or equal to 600 mm, and is larger than 600 mm, the included angles of center lines of adjacent straight grooves are 18 degrees, 7.5degrees and 6 degrees correspondingly. According to the grinding wheel, grinding cooling is significantly improved, service life is significantly prolonged, and grinding quality is improved.

Description

technical field [0001] The invention relates to a precision grinding tool, in particular, the invention relates to a grinding wheel for grinding. Background technique [0002] The grinding wheel generates a lot of grinding heat during the grinding process. Now the grinding heat generated by the grinding wheel during the grinding process cannot be dissipated in time, resulting in the following defects: first, it is easy to produce grinding burns, and the service life is short; second, the grinding debris If the grinding wheel cannot be effectively brought out, it is easy to cause grinding scratches, resulting in poor grinding quality; the third is that the dressing interval of the grinding wheel is short, which reduces the grinding efficiency. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a grinding wheel which significantly improves the heat dissipation of grinding, prolongs the service life and improves the grinding...
