Common questions and answers in the process of using glass machine grinding wheel

Problem 1: The glass still has edge breakage, Angle loss, grinding wheel impression and other undesirable phenomena after grinding by double-sided machine.

Answer: The grinding wheel size selection is inappropriate or poor performance, the granularity should adapt to the thickness range of the processing glass and the processing speed requirements, such as 1,2 grinding wheel installed 80 mesh +140 mesh grinding 8mm-25mm glass is very good, grinding 5-6mm May break the edge, generally should choose 100 mesh +140 mesh match to meet the requirements of 4-19mm. In addition, No. 1 grinding wheel will cause small edge breakage if the distribution of grinding amount is too large. No. 2 should be able to synchronously correct the edge breakage and completely cover No. 1 grinding mark, which is often ignored and has poor performance selection.

Problem 2: The working end Angle of the grinding wheel is more outward than the factory Angle, obviously low outside and high inside inclination, and even appears inside and outside graded step shape.

A: The Angle of the front and rear rings is not appropriate or the motor is loose, the outside of the front ring is too much work, the back ring is not working, the motor Angle needs to be adjusted and fixed in time.

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

A: The front and rear ring Angle is not appropriate or the motor is loose, the outside of the front end is not working, the inside of the back ring is a large workload, should be timely adjusted and fixed motor Angle, reasonable distribution of front and rear ring processing allowance.

Problem 4: There are impact marks on the outside of the grinding wheel, or the end face of the ring sag, alloy shining and other phenomena, can not be used.

A: This phenomenon mostly occurs in chamfered wheel or No. 2 and 3 grinding wheel with finer diamond. The reason is that when changing the grinding wheel or processing thick and thin glass with a large span, the advance and advance position of the grinding wheel is not adjusted in time, resulting in the glass directly hitting the outside of the grinding wheel, or the processing amount allocated is greatly beyond the bearing range of the grinding wheel, and the grinding amount is not corrected in time.

Problem five: The teeth of the whole gear with a depth of about 2mm will break the edge, commonly known as grinding can not be used.

A: The water groove height of the whole gear is equal to the height of the working layer +1.5mm the inner water mouth of the working ring of the grinding wheel remains 1.5mm, indicating that the working layer has been consumed. In order to prevent the remaining 1/3 of the grinding wheel consumption, the glass will impact the matrix outside the grinding wheel due to the large processing allowance or grinding thick glass, the outer side of the working side is designed with 3mm high Angle protection, so the outer side looks like 4mm can not be consumed. The actual working layer is completely consumed.
