Technical Description

The DAINICHI W40R is a heavy-duty horizontal CNC turning center designed for high-precision machining of large workpieces. It features a maximum main spindle turning diameter of 90.550 inches and a maximum turning length of 433.070 inches, accommodating substantial part sizes. The main spindle chuck diameter is 44.000 inches, with a maximum swing of 118.110 inches, allowing for versatile workholding configurations. The machine is powered by a 100 HP main spindle motor, with an optional upgrade to 120 HP, and operates at a maximum spindle speed of 200 RPM, ensuring robust performance for demanding applications. The W40R is equipped with a turret-style primary tool carrier, supporting up to 12 turning tools and 12 rotary tools, enabling efficient multi-operation machining. It supports one simultaneous cutting tool and offers optional secondary milling and drilling functions, both on-center and off-center, with standard 'C' and 'Y' axis capabilities for enhanced versatility. The machine provides three-axis control as standard, with optional four-axis configurations for complex part geometries. Axis travels include 40.000 inches (up to 92.000 inches optional) on the X-axis and 120.000 inches (up to 435.000 inches optional) on the Z-axis, with rapid traverse rates of 157 inches per minute on all axes. The W40R is engineered for reliability, precision, and flexibility in heavy-duty production environments.
