The three-edge milling cutter is widely used in machining operations. It is typically installed on a horizontal milling machine arbor but can also be used on vertical machines (such as machining centers and vertical milling machines) for groove, step surface, and side face milling.  

 1. Plane and Step Surface Milling  

·Suitable for side, plane, and step surface milling.  

·Different diameters of three-edge milling cutters can be selected based on the product structure, combined with customized arbors to process multiple surfaces in one operation.  

·Multi-blade three-edge milling cutter combination processing:  

  ·This method enables simultaneous multi-surface machining, but several factors should be considered:  

    ·Arbor strength: Choose the appropriate arbor diameter and length (overhang) to prevent deformation or breakage due to excessive cutting force.  

    ·Cutting parameters: Optimize feed rate and cutting depth to minimize vibration and tool wear.  

    ·Workpiece stability: Ensure the fixture and workpiece are firmly secured to avoid movement or vibration that could lead to tool damage or part rejection.  

2. Slot Milling  

·Used for milling various slot widths and depths, including:  

  ·Keyway milling 

  ·Spring groove milling  

 3. Other Special Machining Applications  

·T-slot milling: Can be achieved with specialized T-slot cutters for high-precision machining.  

·Arc slot milling: Suitable for workpieces requiring a high surface finish.  

·Custom-shaped slot milling: Supports customized tool designs to meet specific workpiece requirements.  

Thanks to its efficient and versatile design, the three-edge milling cutter is widely used in various precision machining applications. When selecting a tool, it is essential to consider workpiece size, material hardness, and processing requirements to achieve the best machining results.
