Description OF Micro Diameter Square End Mill
Adopting a suitable negative rake angle design that takes into
account the strength and sharpness of the cutting edge, while also
adopting a large core diameter to enhance the rigidity of the
cutting tool and make its cutting and chip removal more stable;
Large capacity chip removal has strong cutting characteristics and
timely discharge during cutting, which can achieve stable and fast
processing, and the workpiece accuracy is more glossy; Adopting a
circular arc blade with edge cleaning design, the milling cutter
has less wear during milling, and the blade is durable and sharp,
matched with a 35 ° spiral groove for smooth chip removal; The
universal chamfered round handle is easy to use, has good
compatibility, enhances the vibration resistance and cutting speed
of the milling cutter, and holds tightly without slipping.

Instructions OF Micro Diameter Square Endmill
1. Before using the carbide micro diameter flat 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 e 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 micro diameter square milling cutter.
5. Note: Not suitable for low speed machines such as rotary table
and electric hand drill.
Applications OF Micro Diameter Square Endmill
The cutting edge of the HRC55 micro diameter square 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.
