In the past 20 years in the stone industry, what breakthroughs have been made in countertop and line processing technology?

For example, the automatic line machine has completed the modeling, grinding and polishing of the line, which can completely replace the human to produce and process the line, and realize the mechanized processing of the line; the waterjet machine cutting the special-shaped plate has completely replaced the manual, and realized the mechanization of the special-shaped plate. Processing

　　 The most difficult stone product processing, the engraved products that rely purely on manual processing are also moving towards mechanized processing, partially replacing manual processing. The continuous development and progress of stone equipment at home and abroad is promoting the upgrading of equipment manufacturing in the stone industry, and the development of stone products in the direction of mechanization, automation, and even intelligence, which frees the stone industry from the shackles of traditional manufacturing technology and realizes Technological changes, changes, and progress towards modern manufacturing.

Countertop manufacturing equipment was produced in Italy as early as the 1990s. The author once introduced Italy in the paper "Application of CNC Technology in Stone Processing" published in the first issue of "Stone" in 2003. The technology of processing table tops with the best stone processing center and automatic continuous edging machine.

　　 At that time, due to the high value of these equipments and the fact that the domestic stone equipment has not yet been manufactured, the labor resources are very abundant. Almost no stone production enterprises use processing centers to process the countertops, and they all use manual labor to process the countertops.

　　 Even now, there are only a handful of stone manufacturers that use machining centers to process countertops with fully automatic continuous edging machines.

Fortunately, many domestic stone processing centers and edge grinding machines can be manufactured by many stone equipment manufacturers, and the quality of the products is also good, so that stone manufacturers have more room for independent choice and no longer need to be affected by Italian stone. Due to the high price of equipment, high-quality countertop products can be manufactured with domestically made low-cost equipment, which can realize the mechanization and automated processing of countertops.

Recently, we have seen some domestic and foreign machining center equipment and fully automatic continuous edging machine equipment used in the processing of countertops, and the processed countertops not only have high production efficiency, low labor intensity of employees, and good quality of processed products. Compared with the traditional manual processing of countertops, it has taken several major steps forward, and has promoted the progress of stone countertop processing technology. This technology of replacing manual processing countertops with equipment should be worthy of vigorous promotion in the stone industry. Promote the mechanized and automated manufacturing of the countertop production process.
