◆ for the processing of the glass bead. Using two sets of cutting and milling inserts, which can complete the two glass bead and the back of the 45 ° cut off the excess part of the presser foot milling ◆ with positioning feet for layering cutting position to ensure that the glazing bead cutting relative dimensional accuracy, eliminating the fan frame after processing and layering tightness after assembly procedures ◆ adopts horizontal installation form, so that clamping profiles simple and smooth cutting tool motion, thus ensuring high precision layering, so that doors and windows appearance.
