This series of products are large-scale multi-functional high-end CNC machine tools independently developed by RIFA. The main components are optimized in cooperation with foreign specialized agencies. The products are compact in structure, beautiful in appearance, rich in functions, complete in configuration, excellent in performance, reliable in quality, and have the characteristics of high efficiency and flexibility. Equipped with a series of functional components, a variety of machine tool functions for customers to choose, to meet customers' personalized needs. This series of machine tools has five coordinate axes: X axis (x1 axis and X2 axis), Y axis (Y1 axis and Y2 axis), Z axis and W axis (W1 axis and W2 axis). X, y and Z axes can realize three-axis linkage. W1 and W2 axes are synchronous axes respectively, with the ability of automatic tool change and accessory milling head change. The machine tool can automatically realize the multi-faceted processing of milling, drilling, reaming, tapping and boring of large and medium-sized box parts. It is suitable for petrochemical, refrigeration, metallurgy and other industries to realize pentahedral processing.
Structural features:
◆ the x-axis is equipped with a double tooth rod clearance elimination gear box and a large module rack imported from Germany. It has high transmission accuracy, strong bearing capacity and durable accuracy!
◆ pentahedral automatic head changing, realizing high-efficiency head changing and high-precision processing.
◆ the moving beam is adjusted and positioned with double gratings, and is hydraulically clamped with the column at multiple points. The rigidity of the overall double column frame is good!
◆ according to customers' needs, right angle head, universal head, extension head and angle head can be configured. The accessories have strong functions.
