Description OF inner-R Carbide End Mill
The HRC55 2-blade inner R milling cutter is made of brand new ultrafine particles of 0.5u m/m Co10% tungsten steel, paired with high-quality oxidation resistance and wear resistance, excellent wear resistance and efficient lubrication to ensure an ultra long service life of the cutter; The blade is covered with AITiSiN coating, which can perform high-speed rough processing to fine processing of heat treated materials, reduce the number of tool changes, and improve processing efficiency; The spiral chip removal groove and full edge seismic design prevent easy chipping, enhance the rigidity of the tool, and make the cutting and chip removal of the tool more stable; The tool body is passivated to reduce the small serrations generated during tool grinding and optimize the smoothness.

Instructions OF internal R Milling Cutter
1. Before using the carbide internal R 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 inner R milling cutter.
5. Note: Not suitable for low speed machines such as rotary table and electric hand drill.
Applications OF internal R End Mill
| Brand | BWIN |
| Flutes | 4 Flutes |
| Product Name | Internal R milling cutter for aluminum |
| Hardness | HRC55 ° |
| Applicable materials | Aluminum alloy, copper, aluminum parts, etc |
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.
