WEISSER A 90 VERTICAL MACHINING CENTER

The WEISSER A 90 is a versatile vertical machining center engineered for precision turning and multi-axis machining operations. This modularly-designed, single-spindle machine features a main spindle with a maximum turning diameter of 15.700 inches and an 8.000-inch chuck diameter, capable of rotating at 4,000 RPM with 30 HP output. The machine accommodates a maximum swing of 15.700 inches, making it suitable for medium to large workpieces. With 12 tool positions and one simultaneous cutting tool capability, the A 90 delivers efficient tool management for complex machining sequences. A rotary tool spindle rated at 20 HP and 5,000 RPM enables additional machining methods such as drilling, milling, and grinding without requiring workpiece repositioning, reducing cycle times and enhancing productivity. The machine's 2-axis configuration provides X-axis travel of 44.480 inches and Z-axis travel of 11.000 inches, offering substantial working envelope for diverse component geometries. Rapid traverse rates and maximum feed rates both reach 2,358 IPM, ensuring swift non-cutting movements and optimized machining speeds. The vertical spindle-slide arrangement combined with modular design flexibility makes the A 90 ideal for cost-efficient complete machining of various batch sizes with high machining and quality requirements. The machine is controlled by Siemens 840D CNC technology, delivering advanced automation and precision control. Its comprehensive feature set and multi-function capability position it as an excellent solution for job shops and production facilities requiring flexible, high-precision turning and milling capabilities in a single machine platform.
