A four-edge coated milling cutter is a common type of milling cutter with four cutting edges, usually used for milling machining. The cutting edge of the coated milling cutter is coated with one or more layers of wear-resistant material to improve cutting efficiency and extend service life.

The four-edge coated milling cutter is suitable for machining various materials, such as steel, cast iron, non-ferrous metals, etc., especially for machining various complex parts and surfaces. Due to its fast cutting speed and large cutting depth, the processing efficiency can be greatly improved.

When using a four-edge coated milling cutter, it is necessary to pay attention to the installation and adjustment of the tool to ensure that the concentricity, perpendicularity and rigidity of the tool and the machine spindle meet the requirements. At the same time, it is also necessary to select the appropriate cutting parameters according to different processing materials and process requirements, such as cutting speed, cutting depth and feed speed.

In short, the four-edge coated milling cutter is an efficient, high-precision, high-reliability milling tool, which is widely used in the field of machining.

Grooving and cutting knives: working principle and selection.

16 1月 2024 | 没有评论 | posted by admin | in Article

Grooving and cutting knives both play an important role in industrial applications, but their design, application and the materials they handle vary. The grooving knife is mainly used to make notches or grooves on the surface of the workpiece, while the cutting knife is mainly used to cut materials such as metal bars or pipes. Understanding the working principles and selection criteria of these two tools is essential to improve cutting efficiency and safety. This paper will deeply discuss the difference and working principle of grooving knife and cutting knife, and provide practical selection suggestions.

I. Shape and structure:

1. The head of the cutting knife is long and the blade is narrow, which helps to reduce the material consumption of the workpiece and ensure that it can be cut to the center when cutting. Therefore, the length of the cutting tool head must be greater than the radius of the workpiece.
2. The grooving knife is similar to the cutting knife, but its shape should be consistent with the grooves. A slotting knife is a long type of tool that is mainly used to make notches or grooves on the surface of the workpiece. It usually includes a cutting edge, a manipulator handle and a fixed fixture, which can be adjusted to cut the required notch on the workpiece surface.
   Second, use:
3. The slotting knife is mainly used to cut the surface of the workpiece and make notches or grooves. It is cut in a one-time (non-continuous) way, by cutting the material on the surface of the workpiece to form the desired notch or groove.
4. The cutting knife is mainly used for cutting metal bars or pipes and other materials. Due to the need to deal with the high-strength material cutting in industry, the cutting knife needs a high hardness, and the commonly used hardness is more than HRC60. The cutting method of the cutting knife requires continuous force to cut the material, so it can make multiple cuts along the length direction of the material being cut.
   Third, hardness:
5. The hardness of the slotting knife is relatively low, because it is mainly cut by cutting the material on the surface of the workpiece.
6. The cutting knife requires a higher hardness to deal with the cutting of high-strength materials, and the commonly used hardness is more than HRC60.

In summary, the grooving knife and the cutting knife are different in shape and structure, use and hardness requirements. In actual operation, the appropriate tool type should be selected according to the needs, and the corresponding operating specifications should be followed to ensure the cutting effect and safety.

Double-edged straight groove combination knife.

Double-edged straight groove combination cutter is a commonly used machining tool, mainly used in milling, cutting and drilling operations. This combination knife consists of two identical or different blades combined through a straight groove to form a complete cutting edge. Double-edge straight groove combination tool is characterized by high cutting efficiency, large cutting force and high machining accuracy, so it has been widely used in the field of machining.

The double-edged straight groove combination knife has many uses. First of all, in milling operations, it can be used to mill surfaces such as planes, grooves, and contours, which can quickly remove materials and improve processing efficiency. Secondly, it can be used to cut metal sheets, pipes, profiles and other materials, with large cutting force, high precision characteristics, can meet various cutting needs. In addition, the double-edged straight groove combination knife can also be used to drill holes on the workpiece, which can drill out the required aperture quickly and accurately, improving the processing efficiency. In addition, it can also be used to cut other types of materials, such as wood, plastic, etc., with a wide range of applicability.

In the use of double-edge straight groove combination knife, it is necessary to choose the appropriate blade and groove type according to different processing needs. For example, in milling operations, it is necessary to select a blade with a larger cutting edge and a groove suitable for the axial force of the milling cutter to obtain better machining results. In addition, it is also necessary to pay attention to the hardness and wear resistance of the blade to ensure the accuracy and efficiency of the processing.

In short, the double-edged straight groove combination knife is an efficient and high-precision machining tool, which can be selected and used according to different processing needs. In use, it is necessary to pay attention to the selection of the appropriate blade and groove, and pay attention to the correct use method and maintenance measures to ensure the accuracy and efficiency of processing.
