Emco Maier CONCEPT MILL 250 VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a robust table measuring 19.67 inches in length by 12.60 inches in width, capable of supporting workpieces up to 220 lbs. The spindle is equipped with an SK-30 taper, a European standard known for its steep 1:10 taper angle and excellent clamping stability, making it ideal for high-precision and high-speed machining applications. The spindle achieves a maximum speed of 10,000 RPM and delivers 9.33 HP (30-minute rating), ensuring reliable performance for a wide range of milling operations. Tooling is managed via an automatic tool changer (ATC) with a capacity of 20 tools and a rapid tool change time of 2.5 seconds, enhancing productivity in production environments. The machine offers three standard axes (X, Y, Z) with optional fourth-axis capability, providing flexibility for complex part geometries. Axis travels are 13.78 inches on X, 9.84 inches on Y, and 11.80 inches on Z, with maximum feed rates and rapid traverse speeds of 394 ipm and 589 ipm respectively across all axes, enabling efficient material removal and fast positioning. The SK-30 taper interface, standardized under DIN ISO 7388-1 (formerly DIN 69871), ensures secure tool retention and high concentricity, particularly beneficial for fine machining and heavy-duty roughing up to 12,000 RPM. This configuration is well-suited for precision CNC milling tasks in industries requiring accuracy, rigidity, and repeatability.
