1. Using double –pole alternate pat-arc institutions and patented alternative arc- extrusion structure, enable switching freely seamlessly docking no need adjust when change materials, enabling smaller minium arc curvature, dealing with complex font processing.

2. The planer is made with hard alloy finished, cutting stable & smooth, blade grain with a number of tips can be used separately ,maintenance –free,, and free, and free grinding, low cost, automatic adjust for plane blade, free adjust for sloting depth.

3. Based on the material hardness to achieve pat bending extrusion bending mechanism and switching agencies, processing,efficiency multiplied
