F11 Series Universal Dividing Head
Universal dividing heads are used for controlled angular division, indexing and milling operations such as gear, spline, slot and multi-face machining. They are selected when the machining process requires precise workpiece rotation and repeatable angular positioning.
Product Overview
This series includes F11100A, F11125A and F11160A universal dividing heads. It follows GB/T2554-2008 and is suitable for controlled angular indexing in milling operations that require repeatable division and stable workpiece rotation.
Typical Applications
- Gear, spline, slot and multi-face machining with controlled angular division.
- Milling-machine and machining-center setups that require repeatable indexing.
- Circular drilling or milling operations with dividing plate and tailstock support.
- Projects requiring precise workpiece rotation during multi-step machining.

FAQ
What is the F11 Series Universal Dividing Head used for?
It is used for controlled angular division and indexing in milling operations, including gear, spline, slot and polygon machining tasks.
How is it different from a rotary table or indexing plate?
A universal dividing head is selected for controlled workpiece division through its dividing mechanism. Rotary tables and indexing plates are generally selected for table-side rotary positioning or simpler fixed indexing work.
What machine or mounting interface should be confirmed?
Check the machine table size, center height, tailstock compatibility, accessory space and the required mounting orientation before selection.
What workpiece size or load should be checked?
Confirm the workpiece diameter, length, weight, overhang and the required center height so the selected dividing head can support the setup.
What indexing accuracy or division requirement should be confirmed?
The required angular division, gear tooth count, indexing method and process accuracy should be checked against the machining task.
Can it be used for gear or helical machining?
It can be selected for gear, spline and related dividing work when the required accessories, calculation method and machine setup are properly matched.
What should be checked before installation?
Check center height, tailstock alignment, fixture clearance, lubrication condition and the operating envelope before installation.
What information is needed for quotation?
Please provide the machine model, workpiece drawing, center height requirement, dividing process, accessory requirement and expected indexing accuracy.
