   Product details

Brief Introduction of CNC Aluminum Door-window Corner Connector Cutting Saw

The CNC Aluminum Door-window Corner Connector Cutting Saw is an automatic machine specially designed to cut aluminum door-window corner connector profiles. Equipped with servo control system and ball screw, the corner-connector profile feeding is full automatic. What you have to do is to place the profile and all the other operation is finished automatically. The machine can meet the requirement of corner-connector cutting when manufacturing thermal-break aluminum windows and doors, with the advantage of high-accuracy and high-efficiency, and is ideal equipment for mass production of aluminum windows and doors.

Aluminum profile cutting machine is major and essential equipment for manufacturing aluminum windows and doors. Cutting is the beginning of making aluminum windows, and one of most important manufacturing procedures in the whole window manufacturing process. The cutting accuracy (such as accuracy error of cutting length, accuracy error of cutting angle) will affect the corner crimping accuracy and corner crimping strength of aluminum windows, and then affect the size accuracy and angle accuracy of finished aluminum windows. STONE Window Machinery guarantees the cutting quality of the aluminum profile cutting machine through use of high quality hard-alloy saw blades, high accuracy liner bearing motional pairs and headstock, and other high quality machine components, and through our strict quality control system. Aluminum profile cutting machines mainly includes double-head cutting saw, single-head cutting saw, corner connector cutting saw, and so on.
