Makino V77 #40 VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a large worktable measuring 55.1" x 27.6", supporting a maximum workpiece weight of 5,500 lbs, making it suitable for heavy-duty machining tasks. The machine operates with a vertical spindle available in a standard #40 taper and optional HSK-A63 taper, capable of reaching a top speed of 20,000 RPM, with an optional increase to 30,000 RPM, powered by a 25 HP motor (30-minute rating) and an optional 23 HP version. It supports a 3-axis travel configuration with X-axis movement of 47.2", Y-axis of 27.6", and Z-axis of 25.6", all with rapid traverse and max feed rates of 787 inches per minute, enabling efficient and precise machining operations. Tool handling is managed by an automatic tool changer (ATC) with a standard capacity of 20 tools, upgradeable to 80 tools, with a tool change time of 5 seconds, but no pallet changer is included. The machine lacks a U-axis rotation feature. This configuration balances high spindle speed, heavy workpiece capacity, and flexible tooling options, making it ideal for a broad range of milling applications requiring precision, speed, and load handling in a 3-axis vertical machining center setup.
