Technical Information:

  • Milling is the most flexible machining method available, and it can process almost any shape.
  • Milling completes metal cutting by rotating a multi-cutting tool to perform a programmable feed motion in almost any direction along the workpiece. This cutting action makes milling an effective general-purpose machining method.
  • The choice of machining methods on multi-spindle machines is no longer easy to choose: in addition to all conventional applications, milling is undoubtedly competitive for machining holes, cavities and surfaces commonly used for turning or thread turning. .
  • The disadvantage of milling flexibility is that there are many variables in the process, the factors to be considered increase, the situation is more complicated, and the optimization brings more challenges.
  • Modern milling is a very common method of machining. With the continuous development of machine tools, milling has evolved into a versatile method for processing a large number of different structural products.
  • The development of modern tools also offers more possibilities, and through the indexable inserts and solid carbide technology, productivity, reliability and quality consistency can be improved.
  • With a certain way of cutting, each cutting edge of the tool can remove a certain amount of metal, so that chip formation and chip removal are no longer a top priority.
  • The most common milling applications are available for generating planes. However, with the increasing number of five-axis machining centers and multi-tasking machines, other processing methods and surface processing methods have also been greatly developed.
  • From the point of view of the part or from the point of view of the tool path, the main types of milling operations include:
  1. Face milling
  2. Shoulder milling
  3. Cavity milling
  4. Profile milling
  5. Groove milling
  6. Thread milling
  7. Slope milling
  8. High feed milling
  9. Plunge milling
  10. Parting
  11. Cycloidal milling
  12. Spiral interpolation milling
  13. Turning
  14. Circular interpolation milling


Milling Application Tips:

  • Use the correct tool pitch for cutting to minimize the number of inserts involved in the cut to avoid vibration, while on the other hand, for narrow workpieces or when milling exceeds space, make sure the inserts are adequate.
  • Check power capability and machine rigidity and ensure that the machine can make the most of the required tool diameter.
  • Cutting on the spindle with the shortest possible tool overhang.
  • Be sure to use the correct feed per blade to achieve the correct cutting action with the recommended maximum chip thickness.
  • In any case, the use of indexable inserts with positive rake grooves provides smooth cutting and lowest power consumption.
  • Climb milling is recommended whenever possible.
  • Select the correct tool diameter that corresponds to the width of the workpiece.
  • Choose the most appropriate lead angle.
  • Position and clamp the cutter correctly.
  • Follow blade maintenance recommendations and monitor tool wear.
  • If you need to consider the use of coolant, milling without coolant can generally be done very well.


Recommended Cutting Parameters:

  • The following cutting parameters are recommended range values ​​and should be adjusted as appropriate after considering the following factors:
    • The specific physical properties of the material being processed.
    • The actual condition of the part blank.
    • The power and rigidity of the machine tool.
    • Clamping rigidity of the tool and workpiece.
    • Balance between tool life and machining efficiency.
