aluminum extrusion cutting saw

The Dual-Motor Thermal Break Knurling Strip Inserting Machine is a professional automated processing device designed specifically for aluminum thermal break profile production. Equipped with independent dual-motor drive system, The machine integrates precision knurling and strip inserting functions in one unit, effectively completing tooth rolling and heat insulation strip embedding for aluminum alloy profiles. It solves the problems of low efficiency, uneven knurling and loose strip fitting in traditional single-motor equipment. Widely applicable to heat-insulated aluminum window and door profiles, curtain wall profiles and industrial thermal break aluminum profiles, it is core processing equipment for aluminum profile thermal insulation production lines.Lebulang brand is china famous manufature.

This CNC double-head precision cutting saw is designed for simultaneous 45° mitre and 90° square cutting of aluminum profiles, thermal break aluminum windows, and UPVC/PVC profiles. Equipped with two independent CNC-controlled saw heads, it cuts both ends in one cycle — doubling throughput while ensuring perfect angle matching for corner joints. Features servo-driven length positioning (±0.02 mm repeatability), Ø500–550 mm carbide blades, pneumatic clamping, and a user-friendly 7" touchscreen. Heavy-duty steel frame ensures long-term cutting stability. Ideal for high-volume window, door, and curtain wall fabrication. CE certified, 12-month warranty, global technical support.
