ACRA 4000SH HORIZONTAL MACHINING CENTER

Technical Description

The ACRA 4000SH is a heavy-duty horizontal machining center designed for large-scale turning and machining operations. This machine features a robust configuration with dual main spindles, each rated at 400 RPM with 25 HP output, enabling simultaneous or sequential processing of large workpieces. The system accommodates workpieces up to 40 inches in diameter with maximum turning lengths of 120 inches, making it suitable for industrial-scale components such as large shafts, flanges, and heavy casings. The primary tool carrier operates on a slide mechanism with one simultaneous cutting tool capacity, optimizing tool positioning and minimizing tool interference during complex machining sequences. With 2-axis control (X and Z), the machine provides 40 inches of X-axis travel and 120 inches of Z-axis travel, offering substantial working envelope flexibility. The 40-inch chuck diameter accommodates large workpieces securely while maintaining precision throughout extended cutting cycles. This configuration is particularly advantageous for industries requiring high material removal rates combined with dimensional accuracy on large, heavy components. The dual spindle arrangement increases production throughput by enabling concurrent operations or allowing sequential workpiece positioning without reclamping. The machine's design emphasizes rigidity and stability necessary for sustained heavy-duty cutting, making it ideal for aerospace, energy, heavy equipment manufacturing, and industrial machinery production environments where oversized workpiece machining is required.
