Description OF arch End Mill
Imported high-quality tungsten steel bars are selected, which have
high hardness and strong wear resistance, improving tool life, and
are suitable for high hardness and high-speed cutting applications;
Adopting AlTiSiN coating, the coating has a multi-layer
nanostructure, heat insulation and wear resistance, protecting the
cutting edge of the milling cutter, and making cutting more stable;
Adopting imported machine tools, meticulously grinding, and
maximizing the size of the chip removal groove while ensuring the
rigidity of the cutting edge to ensure that the cutting tool does
not accumulate chips or stick to the tool, resulting in smoother
cutting; The design of upper and lower arc chamfers facilitates the
processing of deep workpiece edges and reverse chamfer arcs for
drilling.

Instructions OF arch Endmill
1. Before using the carbide HRC55 arch milling cutter , please measure the tool deflection. If the tool deflection
accuracy exceeds 0.01mm, please correct it before cutting.
2. The shorter the carbide extends out of the collet, the better.
If the tool extends out longer, reduce the speed, feed speed or
cutting amount.
3. In case of abnormal vibration or sound during cutting, please
reduce the speed and cutting amount until the situation is
improved.
4. Spray type and air jet type are preferred for steel cooling,
which can improve the use effect of carbide lollipop end mill.
5. Note: Not suitable for low speed machines such as rotary table
and electric hand drill.
Applications OF lollipop Endmill
The cutting edge of the HRC55 lollipop milling cutter is covered with a bronze colored nano coating, suitable for materials within HRC55, including iron, carbon steel,
cast iron, mold steel, alloy steel, tool steel, heat treated steel,
and welding repair steel
Q1. The tool breaks when cutting in or pulling out the workpiece
The feed rate and cutting depth can be reduced, and the cutting
edge length can be shortened to the minimum of the necessary
length.
Q2. Tool breaks during normal machining
Reduce the feed rate and cutting depth.
The tool shall be passivated.
Replace the clamp or spring collet.
The tool with high cutting edge number changes the tool with low
cutting edge number to improve chip removal and prevent chip
blockage.
Replace dry milling with wet milling (using cutting fluid), and use
it with vortex tube gun to reduce tool temperature and avoid tool
overheating.
If the wet milling fluid supply direction is changed from the front
to the oblique rear or transverse top, the coolant flow should be
sufficient.
Q3. The tool breaks when the feed direction changes
(1) Use arc interpolation (NC machine tool), or temporarily stop
(temporarily) feeding.
(2) Reduce (decrease) the feed before and after the direction
change.
(3) Replace the clamp or spring collet.
Q4. Problem: Part of the blade tip breaks
Chamfer the corners with manual grinding.
Change down milling to up milling.
