Product Features
Release Date: 7 Jan 2019
The workbench features a double-station configuration capable of simultaneous cutting of two material plates.
The roller frame is cast in a double-wall structure, providing a high damping coefficient and excellent performance in vibration damping.
High-precision, high-rigidity cone positioning is employed for the roller and retractable reel to effectively control wire network jitter.
A roller-assisted disassembly bracket reduces labor intensity and disassembly time for roller maintenance.
The cutting chamber adopts an electric lifting structure and is accessible from three sides, facilitating easy operation and maintenance.
Equipped with arc compensation, disconnection, and continuous cutting functions.

Frequently Asked Questions
What are the advantages of the double-station configuration?
The double-station configuration allows for the simultaneous cutting of two material plates, significantly increasing production efficiency and throughput compared to single-station designs.
How does the machine ensure cutting precision during high-speed operation?
The machine utilizes high-precision cone positioning for both the roller and retractable reel. This, combined with a double-wall roller frame structure for damping, effectively minimizes wire network jitter.
What types of cutting fluids can be used with the CR680 series?
The system is versatile and compatible with both water-based and oil-based cutting fluids, allowing you to choose the best cooling medium for your specific material requirements.
Is the maintenance of the rollers difficult?
No, maintenance is streamlined via a roller-assisted disassembly bracket, which reduces the labor intensity and the time required for disassembly and routine roller upkeep.
What are the main differences between the CR680C and CR680S models?
The primary difference lies in the maximum processing billet size capacity. The CR680C supports up to 70×680×160mm, while the CR680S is designed for larger billets up to 130×680×160mm.
Does the machine support automated cutting recovery?
Yes, the machine is equipped with advanced functions including arc compensation, disconnection handling, and continuous cutting capabilities to ensure process stability and material safety.
