Description OF Micro Diameter Ball End Mill
The HRC65 micro diameter ball end milling cutter is made by
selecting materials and precision grinding. It is manufactured
using Anka machine tools and German processes to ensure the outer
diameter size and accuracy of the micro diameter milling cutter. At
the same time, it also has excellent characteristics such as high
hardness and good wear resistance. It can perform precision
machining and semi precision machining on heat treated materials
below 65 degrees Celsius; Adopting imported first-class precision
machine tools to grind unique spiral blade angles, sharp and
wear-resistant, high-speed cutting, less prone to tool breakage,
reduced tool replacement times, improved machine tool movement, and
improved milling efficiency; Imported passivation equipment. Fine
and blunt sanding enhances the corrosion resistance and wear
resistance of the cutting tool, ensuring smooth and burr free
cutting, and prolonging the service life of the milling cutter.

Instructions OF Micro Diameter Ball Endmill
1. Use high-precision and high opening equipment and fixtures.
2. When the installation rigidity of machine tools and workpieces
is poor, vibrations and abnormal sounds may occur,
At this point, the speed and feed speed in the table below should
be reduced year-on-year.
3. Use air oxygen cooling or MOL (minimum oil cooling).
4. The side is just pushed away and processed in a straight manner.
5. Try to keep the cutting tool as short as possible under non
drying images.
Applications OF Micro Diameter Ball 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.
