4-flute high-efficiency Carbide ball end mill for high-hardness steel

AE-BM-H

1. Thickness at the center
• Reduces cutting resistance and enables stable performance with extended tool life.

2. Center 2-flute specification
• Controls tear when milling flat areas to improve surface accuracy.
• Secures chip pockets with the center 2-flute specification to control the clogging of chips.

3. Superior ball R precision
• Suitable for a wide range of processes, from roughing to semi-roughing.

4. Unequal flute spacing
• Controls harmonic vibration commonly generated during milling with multiple flutes to enable high-efficiency milling.

Long Tool Life
Exhibits superior endurance in high-hardness steel milling.

Low Cutting Force
Effects of sharp spiral curve and unequal flute spacing enable stable milling with low resistance.

1. Use a rigid and precise machine and holder.
2. We suggest using air blow or MQL (mist).
3. These milling conditions are for an end mill where the tool extension length is 4 times the diameter of the end mill. When length of the tool extension from the machine is long,
reduce the speed and feed and milling depth.
4. The above condition shows an approximate standard for contouring operation (side milling) with a low machining load. If abnormal cutting sounds,
vibration or chattering occur depending on the machining shape, cutting amount, rigidity of the machine or work holding condition, etc., please adjust the speed, feed and the depth of cut.
5. When the radius of curvature is less than 1.5 times the tool diameter, please reduce the speed to 50-80%, the feed rate to 50-80%, and the pick feed to 20-60% of the above shown cutting conditions.
6. When the machining incline angle (β) is more than 15°, please reduce the speed to 40-60%, the feed 30-50%, and the axial cutting depth to 30-60% of the above shown cutting conditions.
7. If the cutting depth is small, it is possible to further increase the speed and feed.

The machining path is on condition of contouring line operation.
