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 | 2 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.
