Stone processing equipment encompasses a variety of tools, including cutting and shaping machines, grinding and polishing systems, and specialized machinery for complex stone forms. The stone industry has grown alongside these technologies, but in China, it remains an emerging sector with certain limitations in both equipment performance and application. While there is still a gap compared to international standards—particularly those set by Italian manufacturers—there is also significant potential for future growth and development.
First, sawing equipment plays a crucial role in the stone industry. In China, many companies rely on imported Italian diamond frames and granite sand saws. Over the years, domestic manufacturers have attempted to replicate this technology, producing their own versions of frame structures and sand saws. However, due to a lack of mastery over key technical aspects, efficiency, cost-effectiveness, and reliability remain lower than those of Italian models. Major domestic producers such as Guangdong Lida, Fujian Shengda, and Jinan Hengyunda are active in this field. Meanwhile, Shanghai Feizhou imports high-quality Italian granite sand saws from BM, which enjoy strong market acceptance. Although marble gang saws are widely used in China and have a relatively mature domestic production base, issues like rail system malfunctions and hydraulic tensioning problems persist. Italian equipment typically uses a double-link system, while most domestic models use a single-link design. Additionally, the application of granite sand saws in many Chinese enterprises is limited, mainly due to a lack of operational expertise, especially in managing slurry supply and mortar mixtures.
Second, grinding and polishing equipment is another essential part of stone processing. Handheld grinders are commonly used for shaped stones, while multi-head continuous grinding and polishing machines are increasingly popular for large flat surfaces and architectural facades. Domestic manufacturers like Guangdong Keda and Fujian Shengda have developed advanced continuous grinding lines that are now widely adopted. Shandong Huaxing even exported its systems to countries like Vietnam and Kazakhstan. Technological advancements have led to more efficient and environmentally friendly solutions, such as resin-based abrasives replacing traditional diamond bits. As technology improves, the integration of electrical control systems with mechanical functions is becoming more common. The trend is toward thinner grinding and wider surface processing, with domestic equipment gradually catching up to Italian standards.
Third, special-shaped processing equipment is an area where China still lags behind. While some large enterprises have introduced CNC machines from Italy for complex stone shapes, domestic options remain limited in functionality. Most processes are still done manually, especially for irregular surfaces. However, there are notable exceptions, such as CNC diamond wire saws, waterjet cutting machines, and 3D milling machines, which have become more sophisticated and widely used. Arc and spherical stone processing techniques are well-developed, and various edging machines have been introduced to improve efficiency and quality.
Fourth, the development trends of domestic stone equipment are clear. The industry is moving toward higher efficiency, automation, and environmental sustainability. More blade numbers, the adoption of numerical control (NC) technology, and the use of eco-friendly tools like diamond wire saws and high-pressure water jets are all shaping the future. As technology continues to evolve, the stone processing industry will likely move toward greater factoryization, information management, and higher productivity with reduced costs. Automation and efficiency will remain central to the ongoing development of stone processing equipment.
