LMT-Fette is pleased to announce the expansion of our high-performance
aluminum machining tools with three
new product lines to solve tough machining problems.
- The AL-HPM-Line is a high-performance end
mill line with corner radii to efficiently machine
from solids. These tools can take heavy chip loads
while delivering ultra-smooth finishes.
- The AL-BALL-Line is a 3-flute ball nose
tool line designed for efficient high feed profile
aluminum die/mold making applications.
- The AL-O-Line is a single-flute end mill
line that cuts both hard and soft aluminum, with or
allowing very high chip-loads and deep cuts common
in nesting and stacking of sheet parts.
The AL-HPM-Line is designed for the extremes of high
speeds and feeds with low chatter, resulting in highly
smooth surface finishes. A common application is block
aluminum machining through either high speed
machining (HSM) methods or high feed machining where
the chip loads and depths of cut are higher. Corner
radii provide smooth bottom finishes. The special double-flute
face helps to eject the chips at high feed rates
eliminating chips from being re-cut or re-welded on to
the finished parts.
The AL-BALL-Line is designed for high production profiling.
The uniquely designed point has more flutes for
roughing in deeper cuts. Near the point, the tool is
effectively a single-flute, generating less heat, reducing
burning or melting when finishing. This makes the AL-BALL
a roughing and finishing tool in one, and can save
significant time in die/mold prototyping.
The AL-O-Line is designed for production roughing and
finishing of non-ferrous alloys such as aluminum,
magnesium, brass, etc. The unique “O”-shaped
flute geometry allows chips to flow through the center
tool, ejecting out the other side. The flutes are polished,
minimizing friction and build-up. The dead-sharp edge
is created with high rake and clearance combined with
a low helix, resulting in lower cutting forces. The lower
cutting forces allows for faster feeds and less deflection
during the cut. This is a perfect tool when the diameterto-
length ratio is over 1:2, in applications such as sheet,
stacked sheets, slab cutting, slotting, and nested.
The new LMT high-performance
aluminum lines are designed specifically for machining
aluminum alloys used
in aircraft industries such as 2024-O, 2024-T3, 6061-O,
6061-T6, 7075-O, 7075-T6.
Softer aluminums are one of the most challenging materials
to cut. The AL-O-Line will out perform all multifluted
tools cutting architectural aluminum alloys. While the
tools will cut soft aluminum without coolant, use
of coolant in softer materials will greatly extend tool
life in architectural materials such as 3003-H and 5052-H
The new LMT high-performance aluminum end mills also
excel in other non-ferrous materials such as brass,
magnesium, and copper alloys.
The primary advantage
of the new LMT high-performance aluminum tools is their
ability to take higher chip
loads and deeper cuts with smaller diameters. The tools
are very quiet in the cut, having a large sweet-spot
range. This means you get more work done with smaller
diameter tools in less time. For example, the singleedge
AL-O-Line tools allow faster feeds while taking deeper
cuts, resulting in less machine passes and faster
overall slotting operations.
A key feature of all of the new LMT high-performance
aluminum tools is the ability to get the heat out in
chip, allowing the tools to run at a cooler temperature.
Using a tool with the least number of flutes necessary
get the job done is normally the best solution. For example,
a single-flute tool cutting 180° per revolution
generates less heat. By design, a single-flute tool allows
larger chips to evacuate through the wide open flute
area. Most multi-fluted tools can take large chips but
there is no place for the chips to go with small flute
