 1. Used for combining the 90 corner of high quality aluminum window and door.2. Adopt new mechanical linkage device, realized complete synchronous corner combining. 3. Adjustable locating device suitable for various sections and sizes processing. 4. Left and right punching heads adopt hard synchronous feeding device, thus avoided useless deformation and made the connection more firmly. 5. Easy machine setting due to the synchronous feeding device. PROCESSING ACCURACY: Connection Seam Error: ¨Q 0.15mm |
