Quick Detail OF Micro Diameter Ball End Mill
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.
