Kaast PORT-MILL 550 VERTICAL MACHINING CENTER

Technical Description

This vertical CNC machining center features a rigid 3-axis configuration with travels of 21.7" (X), 23.6" (Y), and 19.7" (Z), each with a maximum feed and rapid traverse rate of 394 inches per minute, ensuring efficient material removal and positioning. The worktable measures 28" x 24" and supports a maximum workpiece weight of 1,100 lbs, offering substantial capacity for medium to large components. The vertical spindle incorporates a BT40 taper with an optional HSK-A63 taper and reaches speeds up to 10,000 RPM standard, with an optional high-speed spindle achieving 24,000 RPM. Powered by a 25 HP motor (30-minute rating) with a 15 HP optional motor variant, it delivers strong cutting performance for a wide range of materials. The automatic tool changer (ATC) accommodates 16 tools, facilitating efficient tool changes for complex machining operations. The machine lacks support rotary tables, pallet changers, and U-axis capability, focusing on straightforward vertical milling operations. This design emphasizes precision and throughput, suitable for a range of industries requiring versatile vertical machining with moderate to high power spindle capabilities and robust workholding capacity. The machine’s specification balances speed, power, and automation to optimize productivity in general CNC milling tasks.
