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
Feature Advantage:
- 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.
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.
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.
