Description
The Churchill U/PH 3615 is a heavy-duty gear hobbing machine designed for the precise and efficient production of spur and helical gears. Built with a robust and rigid structure, this machine delivers excellent stability and high cutting performance, even under demanding industrial conditions.
This machine features a vertical gear hob spindle with infinitely variable spindle speed, allowing operators to optimize cutting speed for various gear sizes and materials. The solid construction minimizes vibration and ensures consistent gear quality throughout extended production runs.
The hobbing machine is capable of handling large workpieces up to 914 mm in diameter and supports a wide range of gear widths, making it suitable for both medium and heavy machining tasks. The machine’s substantial rotary table (762 mm diameter) and extended travel ranges offer flexibility for different gear configurations.
Powered by a 10 HP (≈7.5 kW) main drive motor, this unit provides reliable power for stable cutting. The horizontal travel of the worktable is 483 mm, while the vertical travel of the tool slide is 381 mm, allowing precise movement control in X and Y axes. The hob slide offers 127 mm travel in the Z axis, enabling effective depth control during gear cutting.
The hob spindle speed is continuously adjustable between 50 and 200 rpm, making it adaptable to different hobbing conditions. Vertical feed rates range from 0.38 to 5 mm per revolution, allowing smooth and controlled engagement of the hob with the workpiece.
Constructed in 1966 and designed for durability, the Churchill U/PH 3615 remains a reliable and fully functional machine capable of handling large industrial gear production. Its sturdy frame, accurate drives, and flexible feed options make it a preferred choice for workshops seeking dependable gear manufacturing performance.
