Patented technology drives a significant leap in production capacity! The rotary tool holder multi-wire cutting machine leads the optical glass processing industry.

Leveraging its patented rotary tool holder technology developed over many years, the multi-wire cutting machines produced by Yutian County Changtong Electronics Co., Ltd. (Changtong Electronics) have achieved widespread and mature application in optical glass processing. They have successfully overcome the challenges associated with cutting large-sized optical glass into precise shapes, offering four core advantages—high efficiency, high precision, energy savings, and space optimization—which comprehensively address industry-wide issues such as insufficient production capacity, elevated costs, and difficulty in maintaining precision, thereby providing strong momentum for upgrading the optical manufacturing sector.
It is understood that the rotating tool holder technology employed in this core application represents a key patented achievement developed by the company over seventeen years of dedicated research. The equipment is capable of performing roller winding processing on materials up to 65 mm thick, enabling batch production of four standard K9 optical glass pieces per operation. Its overall production capacity is equivalent to that of 15 conventional ring-winding machines, marking a significant leap in large-scale manufacturing capabilities. In terms of machining precision, the equipment excels notably: for 49 mm-sized products, the machining tolerance remains consistently within ±5 micrometers, with excellent surface roughness; finished products require no additional grinding or polishing steps and can proceed directly to subsequent production stages, greatly streamlining the manufacturing process.
Compared to traditional processing equipment, this model offers significant comprehensive advantages. In terms of space utilization, a single unit occupies an area equivalent to that of two internal circular slicers or one linear ring slicer but achieves the production capacity of 15 conventional units, significantly alleviating space constraints in factory facilities. Regarding energy consumption, the equipment consumes no more than 10 kWh per hour, saving approximately 30% electricity compared to traditional systems and effectively reducing production energy costs. Additionally, the streamlined processing procedures further shorten material turnover cycles and lower overall processing costs, helping customers achieve the triple objectives of cost reduction, efficiency improvement, and quality enhancement.
The demand for optical glass continues to grow, yet insufficient capacity for cutting large-sized sheets has become a major bottleneck for many manufacturers. Changtong Electronics' rotary tool holder multi-line cutting machine, leveraging mature patented technology, superior processing performance, and outstanding overall benefits, has been widely adopted in the optical industry. Moving forward, the company will continue to focus on advancing precision cutting technology research, continuously optimize product performance, and drive high-quality development in the optical processing sector through innovative solutions.
