Abstract
The invention belongs to the technical field of machining, particularly relates to a heavy-load grinding wheel and further discloses a machining method of the heavy-load grinding wheel. The heavy-load grinding wheel comprises an inner-layer portion and an outer-layer portion made of different raw materials. The raw materials of the two portions and the ratio of the raw materials are screened elaborately, sand of two granularities is combined to form sand with the fine granularity within phi 450 for pressing, and the strength can be effectively enhanced. Meanwhile, the sand of the granularity being C No. 120 is adopted as the raw materials of the inner-layer portion preferentially, the rotation strength achieved after the sand of the fine granularity and a resin adhesive are combined is higher than that of sand of the crude granularity by 20% or above; and the portion with the phi 450 is a non-working face, the portion outside the phi 450 is a working face of the outer-layer portion, and the grinding wheel is used for grinding a steel plate or a round steel workblank. Accordingly, the heavy-load grinding wheel has the beneficial effects of being not likely to be broken and being high in grinding efficiency.
Description
technical field [0001] The invention belongs to the technical field of mechanical processing, specifically relates to a heavy-duty grinding wheel, and further discloses a processing method thereof. Background technique [0002] The grinding wheel is an important cutting tool mainly made of abrasives and applied on the grinding machine. It is generally a circular bonded abrasive with a through hole in the center made of abrasives and bonding agents. Grinding wheel is the most widely used type of grinding tool. It rotates at high speed during use and is suitable for processing various metal and non-metal materials. In the material processing process, the selection of the grinding wheel directly affects the grinding performance and machining accuracy of the grinding machine, so the grinding wheel is an important factor for the performance of the grinding machine. [0003] The slab grinding machine is the equipment used by metallurgical enterprises to process the surface of the...
