Ball Nose End Mill, as we all know ball milling cutters or R cutters. It is a type of cutter that the flute is a spherically curved surface assembled on a milling machine and specifically used for milling curved surfaces or circular arc grooves.

The ball nose milling cutters use a special spherical shape to help extend tool life and increase cutting speeds and feed rates.

Ball end milling cutter features:

Ball Nose milling cutters are generally of integral structure, and the blade is not prone to collapse. They have excellent milling effects when processing 3D surfaces (curved surfaces)as well as machining narrow recessed areas. However, the biggest difference between the ball cutter and the round nose cutter is that no matter how high the rotational speed is, the center of the ball cutter is always stationary, and the center part and the workpiece are not milling but grinding, so the tip of the ball cutter is more prone to wear and tear. At the same time, due to the characteristics of the blade, in the machining of flat workpieces, the machining surface of the ball nose end mills will be relatively rough, so the ball cutter is not conducive to the machining of flat workpieces.

Ball end milling cutter application

The ball end milling cutter can mill mold steel, cast iron, carbon steel, alloy steel, tool steel, general iron, and can profile mill high hardness materials up to 70HR and alloy steel, nickel-based alloy, and titanium alloy. And it can operate normally under high-temperature environments. The maximum temperature to maintain cutting performance is 450-550/500-600 degrees Celsius.

The ball nose end mill cutters are widely used in a variety of curved surfaces, arc groove processing, for processing complex machining surfaces. They can also handle complex processing surfaces. mainly used in mold and turbine manufacturing, aircraft industry and other industries.

Milling Cutters characteristics

1. Suitable for dry and high-speed cutting

2. Processing Angle

3. Excellent surface finish and very high milling efficiency.

4. Supports high speed and high feed milling in backside milling mode.

Processing recommendations

It is recommended to tilt the tool by 15º when machining, to avoid cutting at nearly zero speed in the tool axis. This makes cutting more efficient and increases tool life considerably. Reduced cutting forces. Excellent surface roughness and brightness.

Different cutters have different functions in different fields. If you encounter problems during use or don’t know how to choose a carbide cutter, please contact Baiyang Tools and we will have professionals to answer your questions.
