The crossbeam of the CNC oscillating knife cutting machine is an important part of the CNC knife cutting machine. The verticality of the crossbeam and the column must be ensured, and the weight of the cutting head must be supported at the same time. Therefore, it is not only necessary to reduce the weight of the beam to meet the needs of high-speed operation, but also to ensure the good load-bearing performance of the beam.
At present, most CNC oscillating knife cutting machine production plants use cast aluminum beams and then use milling machines for fine processing. Compared with other metal beams, cast aluminum beams are lighter and can better meet the high-speed operation of the machine. However, ordinary cast aluminum beams have the problems of low density, poor rigidity, and rough casting, and long-term use accuracy cannot be guaranteed.
The Y-axis beam of AMOR CNC oscillating knife cutting machine adopts the extrusion process of aluminum alloy abrasive tools, which solves the problems of low load-bearing, rough casting and machine tool planing of ordinary cast aluminum beams. In addition, the weight of the aluminum alloy extrusion beam is lighter, which can guarantee the high-speed movement of the vibrating knife during processing, reduce the wear of the transmission components by the mechanical inertia during braking, and meet the high-precision and high-speed processing characteristics of the vibrating knife cutting machine.
In addition, aluminum alloy beams also have the following 3 advantages:
[1] After the aluminum alloy undergoes the extrusion molding process and the quenching heat aging process, the overall rigidity and surface quality of the beam are very good, and it has good toughness.
[2] Aluminum alloy has good metal properties-corrosion resistance, light weight, high rigidity, which guarantees the high-speed movement of CNC knife cutting machine processing. Because of its light weight, it can realize high-speed cutting of various complex graphics.
[3] The comparison between the aluminum alloy extruded beam and the cast aluminum beam allows the CNC knife cutting machine to have high-efficiency dynamic performance, greatly improve processing efficiency, and ensure processing quality.
