Screw Machine Components & Complex Shafts

Since 1973, Cook-Leitch Inc. has specialized in custom (per blueprint specification) machined components and complex motor and transmission shafts. We possess a wide variety of machining centers including the traditional yet cost-effective Brown & Sharp, Euroturn, Acme’s, and those are complemented with our diverse single point and Multiple Spindle CNC’ technology (with bar feeders). In addition, we have dedicated machining cells with Rotary Transfer (Hydromat) turning centers. However, our true competitive edge in the machining marketplace is our dedicated personnel and our extensive secondary equipment and vertical integration.
