Product Description

Carbide Milling Inserts R5 Positive Round for Stainless Steel Milling with Polished



  • Core Products, Perfect Replacement for Japanese & Korean Products
  • Special for Stainless Steel, Light Cutting and High Surface Quality
  • High Cost Performance



Feature Advantage:

  • Specialdesighed for the milling ofstainless steel and high-viscosity material processing design and production process, with special coating, excellent performance. Completely replace the mainstream products of Japan and South Korea.
  • The round insert tool means a continuously variable lead angle, ranging from 0 to 90 degrees, depending on the depth of cut.
  • The thin chipping effect is suitable for processing heat-resistant high-quality alloys and difficult-to-machine materials.
  • The round insert has a very strong cutting edge and is suitable for high table feed rates due to the thin chips that are produced along the long cutting edge.
  • During processing, the change in the direction of the cutting force along the radius of the insert and the resulting pressure are determined by the actual depth of cut. The development of modern insert geometries has made round insert milling cutters more versatile because of their smooth cutting action, low machine power and low stability requirements.
  • Round inserts are the first choice for roughing tools that are efficient and have high metal removal rates.
  • For the processing performance of stainless steel, the chip-breaker shape ensures edge strength and is more sharp. With special surface treatment, the cutting resistance is smaller and the cutting is lighter.

Technical Information:

  • 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.
  • Milling is the most flexible machining method available, and it can process almost any shape.
  • 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:
    • Face milling
    • Shoulder milling
    • Profile milling
    • Cavity milling
    • Slope milling
    • Thread milling
    • Groove milling
    • Turning
    • Large feed milling
    • Plunge milling
    • Parting
    • Circular interpolation milling
    • Spiral interpolation milling
    • Cycloidal milling


Milling Application Tips:

  • 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.
  • 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.
  • 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.
  • Choose the most appropriate lead angle.
  • Climb milling is recommended whenever possible.
  • Position and clamp the cutter correctly.
  • Select the correct tool diameter that corresponds to the width of the workpiece.
  • If you need to consider the use of coolant, milling without coolant can generally be done very well.
  • Follow blade maintenance recommendations and monitor tool wear.


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.
