A face mill arbor, also known as a face mill holder, or a mill arbor, is one type of CNC milling tool holder that is especially used for holding face mill, the tool that creates shallow cuts on the surfaces of the workpieces. The face mill arbor ensures the stability of the cutter when it rotates with the spindle and performs the cuts. The CNC face milling tool holders in the precision machining fields are designed in similar forms but handle different cutting tools for conducting different works.
The face mill is the cutter for facing should be securely and firmly held by the face mill arbor, as the cutter would rotate rapidly during the processes. With a face mill arbor, it is able to prevent the cutter from slipping off and make sure the cutter cuts through the workpieces on the right track without deviation. Face mill arbor is used for holding face mill cutters and cutters with radial driving slots exceeding clamping diameter 40.
