How To Carry Out Water Grinding For Quartz Stone Processing.

Due to the high hardness of the quartz stone plate, it has brought some difficulties to the processing. How to polish the quartz stone during the processing has posed great difficulties to the quartz stone manufacturers and processing personnel. The surface glossiness of quartz stone is made by high-speed grinding. It is easy to lose luster and whiten the surface during grinding, which greatly affects the beauty. Let's go on to look at how to mill in processing:
The water mill should maintain the inherent shape and edge shape of the table top. The water mill only plays a role of polishing, and cannot change its shape. It is not allowed to grind the plate into pits. The main tool of the water mill is the pneumatic water mill, and the common model is DK-215. The main consumables are various numbers of water grinding discs. There are six types from thick to thin: 50 #, 150 #, 500 #, 1000 #, 2000 #, and 3000 #. The water mill shall use different types of water mill discs in the order of coarse to fine. The principle of water mill is only to grind the connection position, and the position without residual glue generally does not need water mill.
First check whether the residual glue at the splice is scraped clean. If not, use an angle grinder to grind off the large residual glue. During the water mill, hold the water mill with both hands, make the grinding plate form an angle of 5 ° - 10 ° with the plane to be ground, and make the width of the water mill as narrow as possible. Gently grind the residual glue at the connection port with the edge of the grinding plate, until both sides of the connection are flat. Note: check the flatness of grinding by touching or leveling with aluminum alloy while grinding. After grinding, replace the water grinding disc in sequence, and directly grind the sand mark of the previous water grinding until it is invisible in the same way. Note: Use a rag to dry while grinding to check whether the sand mark is well ground. Until all types of water grinding discs are grinded. After grinding all the abrasive discs, dry them with a clean rag to check the smoothness and glossiness of the connecting port and whether there are obvious sand marks. Rework and regrind the parts that are not in place.
Place the water retaining edge on the water grinding table at the water retaining edge and fix it. Check whether the width of the whole water retaining edge is consistent. Do not use inconsistent ones. Then check whether the arc of the water retaining edge has gong misalignment. The arc is correct on the front side and misaligned on the reverse side. During the water mill, hold the water mill with both hands and walk along the arc of the water retaining edge to ensure that the arc of the water retaining edge is not deformed. After grinding one abrasive plate, replace the next abrasive plate. Grind it in the same way until the previous sand mark is removed. Repeat this process until all types of abrasive plates are finished. After grinding all the abrasive discs, dry them with a clean rag to check the smoothness and glossiness of the connecting port and whether there are obvious sand marks. Rework and regrind the parts that are not in place.
