1、 Structural characteristics
Three sided blade design
The circumferential surface and both end faces of the milling cutter are equipped with cutting edges, forming a "three sided edge" structure. This design allows the tool to participate in cutting simultaneously during machining, improving machining efficiency.
Wrong tooth arrangement
The cutting edge of the tool adopts a staggered tooth arrangement, that is, the cutting edges of adjacent teeth are offset by a certain angle in the circumferential direction. This design can reduce vibration and noise during cutting, improve the smoothness of the machined surface, and extend tool life.
Blade tooth shape
Knife teeth are usually made of hard alloy or high-speed steel, which have high hardness and wear resistance. The shape and angle of the cutting teeth have been optimized to meet different processing requirements.
2、 Application scenarios
Milling grooves
Misaligned three sided milling cutters are very suitable for milling grooves of various widths, especially those with larger depths. The three sided blade structure can efficiently remove materials while ensuring the dimensional accuracy of the groove.
Processing step surface
When machining step surfaces, the end cutting edge of the tool can participate in cutting simultaneously, improving machining efficiency and reducing the number of tool changes.
Milling keyway
Due to the good rigidity of the cutting tool and the uniform distribution of cutting edges, three sided milling cutters with staggered teeth are commonly used in precision machining applications such as milling keyways.
Other applications
It can also be used for milling special shaped grooves such as T-shaped grooves and dovetail grooves, as well as for side milling.
3、 Advantages
Efficient cutting
The three sided blade design and staggered tooth arrangement enable the tool to simultaneously participate in multiple cutting edges during cutting, significantly improving cutting efficiency.
High processing quality
The staggered arrangement reduces cutting vibration, resulting in better surface smoothness and dimensional accuracy.
Long tool life
Reasonable tooth arrangement and material selection make the wear of the tool more uniform, extending the service life of the tool.
Wide applicability
Suitable for processing various materials, including steel, cast iron, non-ferrous metals, etc.
4、 Precautions for use
Tool installation
Ensure that the tool is securely installed to avoid machining errors or tool damage caused by looseness.
Selection of cutting parameters
Reasonably select cutting speed, feed rate, and cutting depth based on processing materials and tool specifications to achieve the best machining effect.
Cooling lubrication
During the machining process, sufficient coolant should be used to reduce cutting temperature, minimize tool wear, and improve the quality of the machined surface.
regular inspection
Regularly check the wear of cutting tools and replace severely worn tools in a timely manner to ensure machining quality and efficiency.
5、 Comparison with other cutting tools
Compared with ordinary three sided milling cutters, the main advantage of staggered three sided milling cutters lies in their staggered tooth arrangement design. This design can significantly reduce cutting vibration and noise, improve the smoothness of the machined surface, and extend tool life. In addition, the three sided milling cutter with staggered teeth has more outstanding efficient cutting ability when machining deep or wide grooves.
