Grinding method for controlling surface roughness of different rolls

Abstract

The invention relates to a roller grinding processing method, in particular to a grinding method for controlling the roughness of the surfaces of different rollers through sand wheels of the same type used on a numerical control roller grinding machine. The method comprises the following steps of: trimming the sand wheels to guarantee the balance of the sand wheels and the flatness and fineness of the working surfaces of the sand wheels; and after the sand wheels are trimmed, performing roller precision grinding in three steps, namely rough grinding, mediate grinding and fine grinding, wherein the grinding precision and the cylindricity of the rollers are smaller than 0.005mm, and the coaxiality is smaller than 0.005mm; and setting required grinding parameters according to different roughness requirement values, and carrying out grinding according to the roughness requirement values in three passes in a non-spark state. The method is simple and is easy to operate; the working efficiency of a machine tool and the working efficiency of a rolling machine can be improved; the roller replacement frequency of the rollers is reduced; the on-line time of the rollers is prolonged; the plate shape and the surface quality are improved; and therefore, the cost is reduced and the benefit is improved.

Description

Technical field [0001] The invention relates to a roll grinding processing method, in particular to a grinding method in which the same type of grinding wheel is used on a numerically controlled roll grinder to control the surface roughness of different rolls. Background technique [0002] The production of high-surface-quality plates, strips and parks largely relies on rolls with high-surface grinding quality, and the surface roughness of the rolls is the most important factor affecting the grinding quality of the rolls. In the actual use of rolls, the roll roughness of each stand has different requirements. The roll surface roughness does not meet the requirements, which will cause defects in the shape and surface quality of the rolled product, and the surface roughness of the roll is uneven or The surface roughness of the upper and lower rolls is inconsistent, which will shorten the online time of the rolls and change rolls frequently, thereby increasing the amount of roll gri...
