Welcome to the heart of STON CNC. Explore our expansive 20,000㎡ facility where precision engineering meets full-link independent manufacturing.
Unlike mere assembly plants, STON is a true manufacturer. Our expansive 20,000-square-meter self-owned facility is equipped with industry-leading heavy machinery, including advanced gantry processing centers and CNC floor-standing boring machines.
This robust infrastructure allows us to independently complete the entire manufacturing cycle of our sheet metal fabrication equipment—from the casting of the machine bed to the final precision assembly. By maintaining absolute control over every component, we guarantee an exceptional assembly accuracy within ±0.05mm. This full-link independent processing not only ensures superior machine rigidity and durability but also allows us to rapidly adapt to custom non-standard requirements and guarantee a lifetime supply of spare parts for our global clients.

From a dedicated local manufacturer to a globally recognized brand exported to over 80 countries, STON's history is a testament to our relentless pursuit of engineering excellence.
Independently completes the material cutting process, ensuring that the material specifications meet international standards.
Large floor-type boring and milling machines are used to complete the machining of the fuselages and components.
Pre-cutting process, quickly removes most of the excess metal material from the workpiece blank.
Ensure that the dimensional accuracy, geometric tolerances, and surface roughness of the workpiece fully meet the requirements of the design drawings.
Annealing and shot blasting are performed to eliminate internal stress in the components and fuselages.
By demonstrating the formation of a pressure layer during plastic deformation, the fatigue resistance of the workpiece can be improved.
All installations are measurement-based, and assembly is carried out strictly in accordance with standardized operating procedures.
Perform process inspections according to SIP to ensure cumulative tolerances are met.
Every CNC sheet metal machine bearing the STON name is the result of a meticulously controlled 9-step manufacturing process. This uncompromising approach is how we deliver industrial-grade reliability to factories worldwide.
