Carbide Milling Inserts SEMT12T320 for Shoulder Milling with R2.0

Feature Advantage:

• Complete replacement for Sandvik 290.
• The main application range is shoulder milling.
• Radial forces are mainly generated in the feed direction.
• The machined surface will not be subjected to high axial pressures, which is advantageous for poorly ground or thin-walled workpieces and for unsteady clamping.
• Good versatility.
• Comprehensive consideration of various factors, a reasonable combination of a variety of ideal coatings, so that the insert in all kinds of steel, stainless steel, cast iron and other materials have excellent performance.

• Grade:

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.
• 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.
• Shoulder milling produces two faces at the same time, which requires peripheral milling and face milling.
• Getting a true 90 degree shoulder is one of the most important requirements.
• Shoulder milling can be done with conventional shoulder milling cutters or with end mills, long edge milling tools and three-sided milling cutters. Due to the many options, it is necessary to carefully consider the processing requirements in order to make the best choice.

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.
• 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.
