2. Punch press is used to punch holes in aluminum profiles, which can make square, rectangular and circular holes. Punch press is the equipment used by large aluminum alloy doors and windows manufacturers, and the small processing points are replaced by other equipment, which is far less accurate and efficient than punch press.
3. The copying milling machine is mainly used for milling the keyhole on the profile. The copying milling machine can mill holes according to the shape of the template, which can be square, round, oval, splayed, etc. It has the characteristics of intelligent hole milling, high precision and high speed. The cost of copying milling machine equipment is relatively high, and there are generally no small machining points, so manual opener is generally used instead.
4. This corner fitting machine is mainly used for corner fitting of aluminum alloy door and window profiles, which has the characteristics of high precision and beautiful corner fitting. Generally used in large aluminum alloy doors and windows factories, small processing points are generally used for manual corner assembly.
