Henan quality supervision and inspection results, the qualified rate of grinding wheel products is 86.1%
In the fourth quarter of 2011, Henan Provincial Technical Supervision Bureau organized regular supervision and inspection of the quality of grinding wheels in the province. A total of 194 batches of 130 grinding wheel manufacturers were selected, and 167 batches were qualified. The sampling rate of products was 86.1%. , a decrease of 7.9 percentage points over the same period last year. In this inspection, it was found that among the 27 batches of unqualified products, the rotation strength of 6 batches of products was unqualified, the pore size of 21 batches was too large, and the pore size of 2 batches was too small. Among them, Zhengzhou Xihu Abrasives Co., Ltd.'s "Eight Seven Towers" 100×6×16-A/F30 Q4 BF-7m/ s grinding grinding wheel (Oct-11), Boai Huaqing Abrasives Factory "Clarification" 100×6×16-A/F30 P4 BF-70m/s grinding wheel (2011-11-6), the unsatisfactory rotation strength and the large aperture are unqualified. The quality supervision department pointed out that the rotating strength of the grinding wheel is unqualified, and the turning and breaking occurs during use, which will directly threaten the user's life safety and property safety. If the diameter of the grinding wheel is too large, the grinding wheel may easily cause eccentricity of the grinding wheel, affecting the quality of the grinding process and even causing the rupture; if the hole diameter is too small, the grinding wheel cannot be installed and used. If the spindle is forcibly installed, the spindle is easily scratched, causing a dark injury to the grinding wheel, resulting in a rotary rupture. The main reasons for the decline in the quality of this grinding wheel product are as follows: First, the company’s compliance standards are not in place after the new standards are issued, and they are not strictly implemented according to the new standards. Second, the production molds and new plug gauges are not replaced in time according to the new standards. The standard requirements do not match.
