Shibaura Machine Co. VMC-550 VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a 55.1" x 23.6" table capable of supporting workpieces up to 3,300 lbs, providing a robust platform for heavy-duty machining. The spindle is vertically oriented with a BT50 taper, delivering 10 HP at a 30-minute rating, with an optional upgrade to 15 HP and a top speed of 5,000 RPM, suitable for a wide range of milling, drilling, and tapping applications. The tool system includes an automatic tool changer (ATC) with a standard capacity of 24 tools, expandable up to 40 tools, enabling efficient tool management and reduced downtime. The machine operates on a standard 3-axis configuration (X, Y, Z) with optional 4-axis capability. Axis travels are 43.3" in X, 21.7" in Y, and 22" in Z, with maximum feed rates of 236 inches per minute for precise movement control. Rapid traverse rates reach 630 inches per minute across all three axes, enhancing cycle times. The table is designed with sufficient rigidity to handle the specified maximal workpiece weight, ensuring stability during machining. Additional features include a 360° B-axis rotation, facilitating complex part orientation and machining flexibility. This vertical machining center integrates high rigidity, precision ball screws, and linear guideways for smooth feed motion, providing excellent positional accuracy and repeatability suited for demanding industrial applications requiring robust construction and versatile tooling capacity.
