SEET12T3 Carbide Milling Inserts with 45 Degree Positive Square with Processing a Variety of Materials
- The first choice for face milling
- Completely replace Sandvik R245
- SEET12T3 is the first choice for most materials from roughing to finishing face milling.
- A 45 degree lead angle tool has both radial and axial cutting forces of similar magnitude, which results in a more sturdy pressure and a relatively low machine power requirement.
- This lead angle is suitable for general purpose face milling. It is also particularly suitable for milling workpieces with short chip materials, as excessive radial cutting forces are left at the ends of the cuts as the amount of material is reduced. This is also reflected in the fact that the cutting edge is lighter at the beginning of the cut, which reduces the tendency to vibrate when milling with large overhangs or small tool holders.
- Thinner chips in many applications achieve high productivity because the table feed range is greater while maintaining a medium cutting edge load. Often this compensates for small depths of cut that can leave small angles of cutting ability.
- High metal removal rates and good surface quality are achieved, often eliminating subsequent finishing operations.
- The insert has a 2mm wiper for high feed rates.
- Brighter surfaces can be obtained with high cutting speeds.
- For viscous materials (ISO M and S), use a coolant or oil mist.
- For optimum surface quality, a PVD coating can be used with a sharp cutting edge and a depth of cut of 0.5 to 0.8 mm.
- The vibration trend can be reduced because most of the cutting force is axial.
- 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.
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.
