During CNC machining, particularly in the roughing stage of steel parts, cast iron components, and mould manufacturing, the face mill holder is typically responsible for heavy material removal. This type of operation is characterised by high cutting torque and heavy load, placing strict demands on the rigidity and stability of the tool holder. For this reason, face mill holders, with their robust structure and excellent torque transmission capability, have become an irreplaceable tool holder solution for rough machining operations.
What Is a Face Mill Holder?
A face mill holder is a type of tool holder designed for mounting shell mills. Its structure typically uses a central clamping screw together with matching drive keys to secure the shell mill against the holder’s flange face, providing reliable axial positioning and efficient torque transmission.
Unlike other tool holder types, a face mill holder transmits cutting torque directly through its mechanical structure. This gives it a clear advantage in applications involving large depths of cut and heavy cutting loads.
Application Scenarios of Face Mill Holders
Large-area face milling of steel and cast iron parts, rough machining operations on CNC machining centres, rough machining of mould cavities and base surfaces, and high-efficiency face milling in mass production. In these operating conditions, machining efficiency and stability are often prioritised over surface finish, allowing face mill holders to fully demonstrate their structural advantages.
Limitations of Face Mill Holders
Although face mill holders offer clear advantages in rough machining, they are not suitable for all machining scenarios. Due to the relatively large flange diameter and bulky overall structure, they are not well suited for deep cavity machining or operations close to workpiece side walls, where interference can be significant.
In addition, their dynamic balancing performance is inferior to that of shrink fit tool holders or hydraulic tool holders, making them generally unsuitable for high-precision machining conditions. For machining stages with higher requirements for surface quality and accuracy, shrink fit tool holders or hydraulic tool holders are more appropriate choices.
With their strong torque transmission capability and stable, reliable structure, face mill holders occupy an irreplaceable position in the field of CNC rough machining. Proper tool holder selection not only improves machining efficiency, but also ensures safety and stability throughout the machining process.
As a manufacturing factory, our products are always developed based on real machining scenarios. We are able to customise tool holders according to the customer’s actual production environment, helping customers improve machining efficiency while also supporting long-term, stable development.
