Emco Maier CONCEPT MILL 450 VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features a rigid worktable measuring 27.56 inches in length and 20.40 inches in width, supporting workpieces up to 1,100 lbs. The spindle is vertically oriented with an SK-40 steep taper interface, providing excellent tool holding stability and rigidity suitable for high-speed precision machining up to 12,000 RPM. The spindle delivers 14.6 HP (30-minute rating), ensuring robust power for heavy-duty milling operations. Tooling is managed through an automatic tool changer (ATC) with capacity for 20 tools, enabling efficient tool swaps in 8.2 seconds, minimizing cycle times. The machine operates with 3 axes of movement (X, Y, and Z), with travel distances of 23.62", 19.68", and 19.68" respectively, and a maximum feed rate of 394 inches per minute across all axes, while rapid traverse speeds reach up to 945 inches per minute. The spindle’s SK40 taper, standardized by DIN ISO 7388-1, features an 8° 17'50" angle providing superior concentricity and clamping stability essential for accuracy and repeatability in machining. The SK40 taper supports larger tooling with strong rigidity, making it suitable for a wide range of applications from fine finishing to heavy roughing. The combination of a powerful spindle, high-capacity ATC, and precise axis travels equips this machine for versatile and efficient manufacturing tasks in demanding production environments.
