Problem 1: After the glass is ground by a double-sided machine, there are still undesirable phenomena such as edge chipping, corner drop, and grinding wheel marks.

Answer: The size of the diamond grinding wheel is not suitable or the performance is poor. The particle size should be adapted to the requirements of the glass thickness range and processing speed. For example, the No. 1 and 2 grinding wheel is equipped with a 80 mesh 140 mesh grinding wheel, which is good for grinding 8mm-25mm glass, and 5-6mm. The glass may collapse. Generally, a 100-mesh and 140-mesh grinding wheel should be selected to meet the requirements of 4-19mm glass. In addition, if the grinding amount of the No. 1 grinding wheel is too large, it will cause small chipping. The No. 2 should be able to simultaneously correct the chipping and completely cover the No. 1 wear scar. Often the No. 2 is ignored and the selected performance is poor. Although the appearance is the No. 1 problem, it should be Replace the high-performance No. 2 wheel and re-adjust to allocate the machining allowance reasonably.

Problem 2: The angle of the working end face of the diamond grinding wheel is more outwardly inclined than the factory angle.

Answer: The front and rear ring angles are inappropriate or the motor is loose, the outer side of the front ring has too much work, and the rear ring is not working, and the motor angle needs to be adjusted and fixed in time.

Problem 3: The working end face of the diamond grinding wheel is close to the level, even the outside is high and the inside is low, and the remaining 1/3 cannot be used.

Answer: The front and rear ring angles are inappropriate or the motor is loose, the outer side of the front end is not working, and the inner side of the rear ring has a large workload. The motor angle should be adjusted and fixed in time, and the machining allowance of the front and rear rings should be allocated reasonably.

Problem 4: There are impact marks on the outside of the grinding wheel, or there is a ring-shaped depression on the end surface, and the alloy is shiny, etc., and it cannot be used.

Answer: This phenomenon mostly occurs in chamfering wheels or grinding wheels with fine diamonds No. 2, 3, because when replacing new grinding wheels or processing thick and thin glass with a large span, the advance and retreat position of the grinding wheel is not adjusted in time, causing the glass to directly hit the outside of the grinding wheel. , Or the allocated processing volume is far beyond the bearing range of the grinding wheel, and it is caused by not stopping the machine in time to make corrections. Pay attention to retreating the grinding wheel first, and gradually follow up the grinding volume.

Problem 5: If the full gear has teeth with a depth of about 2mm, the edges will collapse.

Answer: The depth of the nozzle groove of the full gear = the working layer height 1.5mm inside the working ring of the grinding wheel. The remaining 1.5mm of the nozzle indicates that the working layer has been consumed. In order to prevent the grinding wheel from consuming the remaining 1/3, due to large machining allowance or thick grinding When glazing, the glass will impact the outer substrate of the grinding wheel. The outer side of the working side is designed with a 3mm high corner, so the outer side seems to have 4mm of consumption, and the actual working layer has been completely consumed.
