Giddings & Lewis PC-50 CNC Horizontal Boring Mill

The Giddings & Lewis PC-50 Horizontal Boring Mill is a powerful, precision-engineered CNC machining platform designed for large-part manufacturing, heavy cutting, and high-accuracy boring and milling applications. All specifications are approximations and subject to verification. This machine is ideally suited for industries such as aerospace, energy, heavy equipment, defense, and large-scale industrial fabrication where rigidity, horsepower, and precision are critical.

Featuring a robust 5.12-inch spindle diameter with a #50 ANSI B5.50 taper, the PC-50 delivers exceptional cutting strength and tool holding capability. The spindle is capable of speeds up to 4,000 RPM and is powered by a 50 HP motor, providing the torque and performance required for heavy material removal as well as precision finishing. The W-axis spindle travel of 31.5 inches enhances deep boring capability, while coolant through spindle and flood coolant systems support improved chip evacuation and tool life.

This horizontal boring mill offers generous axis travels, including 98.4 inches of X-axis (horizontal table travel), 82.7 inches of Y-axis (vertical head travel), and 62 inches of Z-axis travel. The large 49.25-inch by 63-inch built-in rotary table supports workpieces up to 25,000 pounds, making it ideal for machining substantial castings, weldments, and large structural components. The table index rate of 5 RPM allows for precise positioning during multi-sided machining operations, and rapid traverse speeds of up to 590 IPM help reduce non-cutting time and improve overall productivity.

Equipped with the Siemens Sinumerik 840D CNC control, this machine offers advanced programming capability, high-speed processing, and excellent motion control. The 60-station automatic tool changer significantly enhances flexibility for complex part programs requiring multiple tools. A Renishaw OMP 60 probe is included for in-process inspection and setup verification, helping maintain tight tolerances and reduce manual setup time. Heidenhain linear scales further improve positional accuracy and repeatability across all axes.

Additional features include a power drawbar, paper filtration system, and chip conveyor for efficient chip management and coolant cleanliness. The machine operates on 460V, 3-phase power at 225 amps. With overall dimensions of approximately 240 inches by 300 inches by 197 inches high and a weight of approximately 70,000 pounds, the Giddings & Lewis PC-50 offers the mass and structural integrity required for demanding heavy-duty machining environments.

Offered at $87,500, this Giddings & Lewis PC-50 Horizontal Boring Mill represents an excellent value for manufacturers seeking a large-capacity CNC boring mill with high horsepower, extensive tooling capacity, and advanced control capabilities.
