AI Technical Summary
Existing roller surface cutting technology suffers from problems such as high processing difficulty, insufficient precision, high cost, significant environmental risks, and poor equipment synergy, especially when processing high-hardness rollers or complex curved cutting lines.
By employing a laser wire feeding device and a fixing device working in tandem, material cladding is achieved through laser energy. Combined with a subtractive cutting device for precise trimming, high-strength cut lines are formed, avoiding the wear and environmental hazards of traditional methods and improving processing accuracy and efficiency.
It enables efficient and low-cost printing of high-strength blade lines on rollers, solving problems such as high processing difficulty, insufficient precision, and significant environmental hazards in traditional methods, and significantly improving the mechanical properties and production efficiency of the blade lines.
