WELE AA1890 VERTICAL MACHINING CENTER

Technical Description

The WELE AA1890 Vertical Machining Center is a high-performance, boxway-type CNC machine engineered for demanding industrial applications. Featuring a robust three-axis configuration (X: 70.87 inches, Y: 35.43 inches, Z: 35.43 inches), it delivers precise and reliable machining for complex workpieces. The machine is equipped with a generously sized table measuring 76.77 inches in length and 35.43 inches in width, providing ample workspace for large or multiple parts. Designed with heavy-duty sliding guides and a mechanical two-speed geared head, the AA1890 ensures high torque and flexibility for both roughing and finishing operations. The spindle, directly coupled to the precision head, supports a maximum speed of 6000 rpm (optionally up to 10,000 rpm) and is powered by a 22–26 kW motor, enabling efficient high-speed cutting. The machine utilizes a Fanuc 0iTF PLUS CNC control system for seamless operation and programming. With a rapid feed rate of 12,000 mm/min on the Z-axis and a cutting feed rate range of 1–10,000 mm/min, the AA1890 achieves excellent productivity and accuracy. The tool magazine capacity is 30 tools, with a maximum tool diameter of 110 mm (200 mm if adjacent pockets are empty), a maximum tool length of 300 mm, and a maximum tool weight of 15 kg. Positioning accuracy is rated at ≤0.020 mm and repeatability at ≤0.010 mm (VDI/DGQ 3441). The machine’s overall dimensions are 5300 mm (208.7 in) in length, 3300 mm (129.9 in) in width, and 3620 mm (142.5 in) in height, with a total weight of 20,000 kg (44,092 lb). This machining center is ideal for high-precision, high-efficiency production environments.
