AMERA SEIKI S-40 HORIZONTAL MACHINING CENTER

The AMERA SEIKI S-40 is a horizontal machining center designed for precision turning and milling operations on large cylindrical workpieces. The machine features a single main spindle with a 21-inch chuck diameter capable of handling workpieces up to 26.77 inches in turning diameter and 78 inches in length, with a maximum swing of 39.76 inches and bar capacity to 6.5 inches. Operating at 600 RPM with 50 HP output, the spindle delivers substantial torque for heavy-duty machining tasks. The machine utilizes a turret-based tool carrier system with capacity for 12 turning tools and 12 rotary tools, enabling one simultaneous cutting operation. The two-axis configuration (X and Z) provides 21.06 inches of X-axis travel and 78.7 inches of Z-axis travel, with rapid traverse rates of 590 ipm across all axes, ensuring efficient positioning and tool changes. This architecture makes the S-40 particularly suited for manufacturing operations requiring extended workpiece lengths with controlled diameter work, such as spindle production, valve bodies, and precision shaft machining in industrial applications.
