The use of quartz stone for kitchen countertops has become a popular trend. Although quartz stone belongs to artificial stone products, its hardness has become the top of indoor decorative stones, with a maximum hardness of 7 Mohs (monochromatic particle board), second only to the hardness of diamond. So, the processing technology requirements for finished products are very strict.

The composition of the quartz stone countertop also includes front and rear water blocking and countertop, most of which are directly pasted, and better hanging ones will use 45 ° splicing. However, the most popular method recently is the production of back arcs. Choosing the back arc process will incur additional fees, but many craftsmen are unwilling to make it because the production of low back arcs is very troublesome and prone to errors. How to make a circular low arc? Let's take a look together.
     It is very difficult to make a round low arc with quartz stone, and the size measurement must be accurate. Once there is a mistake in the cutting process, it cannot be compensated. Moreover, after processing, the arc needs to face obvious problems such as discoloration and adhesive lines, which is impossible to handle like the original sheet metal. The production of circular low arc should first bond a stone strip of about 3cm, and cut it off before cutting; Then, after pasting, block the water and use both F-clip and A-clip to fix it simultaneously. The tighter the clip, the less obvious the adhesive line. Alternatively, you can choose the bottom cleaning process, which requires additional charges.
    After bonding, use a touch head for polishing. CNC grinding machines can be used for polishing, or edge grinding machines can be used to replace the grinding head. Finally, manual polishing is necessary, but manual polishing is time-consuming. Don't ask me which polishing number to use. Actually, all machines require manual operation, so the experience of a processing technician is the most important. After rough and fine grinding, polishing is required, which is also the most important step and a test of the master's skills. Using a water grinding plate to polish from the first plate to the sixth plate in sequence will restore the original luster, and the selection of a plate is also crucial.
