In which industries are three sided milling cutters with embedded teeth applied
A three sided milling cutter with embedded teeth is a milling tool with high efficiency and versatility. Its cutting edge is distributed on the cylindrical surface and two end faces (i.e. "three sided blade"), and the blade adopts a replaceable embedded tooth structure (usually a hard alloy blade), which has the characteristics of strong durability, sharp cutting edge, repeatable grinding or blade replacement. This type of tool is widely used in industries that require groove machining, step milling, side milling, and other scenarios for workpieces. The specific application areas are as follows:Sources：www.hafc.net.cn | PublishDate：2025.07.08
1. Mechanical manufacturing and processing industry
This is the core application area of the three sided milling cutter with embedded teeth, mainly used for milling various mechanical parts:
Groove processing: milling right angle grooves, step grooves, key slots, etc. on shaft, disc, and plate parts, such as gear shaft key slot processing, flange positioning groove processing, etc.
Step surface milling: Milling the stepped surface of parts to ensure the verticality and flatness of the steps, such as the step surface of machine tool guides and the parting surface of molds.
Side milling: precision milling of the vertical side of the workpiece to ensure its perpendicularity to the reference plane, suitable for processing box and frame parts.
2. Mold manufacturing industry
The structure of mold parts is complex and requires high dimensional accuracy and surface quality. Three sided milling cutters with embedded teeth play an important role in this field
Groove processing of mold cavities or cores: For example, grooves used for exhaust and positioning in plastic molds and stamping molds need to be correctly milled with a three sided milling cutter.
The step and side processing of the mold template: The splicing surface, guide groove and other parts of the template need to ensure high parallelism and perpendicularity, and the rigidity and accuracy of the toothed three sided milling cutter can meet the requirements.
3. Automotive manufacturing and parts processing industry
In the processing of automotive components such as gearboxes, engine blocks, chassis components, etc., a large number of grooves and step structures are involved:
Milling the keyway of the gearbox gear shaft: Ensure the correct fit between the gear and the shaft to transmit torque.
Machining of oil and water channels in the engine cylinder block: ensuring the dimensional accuracy of fluid channels and avoiding leaks.
Step surface processing of chassis bracket: The installation surface of the bracket needs to be in contact with other components, and the flatness is ensured through milling.
4. Rail Transit and Aerospace Industry
This type of industry has high requirements for the strength and accuracy of parts, and three sided milling cutters with embedded teeth are commonly used for:
The frame processing of railway vehicle components, such as the connecting steps and positioning grooves of the carriage frame, requires high-strength cutting tools to ensure processing stability.
Precision milling of aerospace parts, such as the side of aircraft fuselage frames and grooves in engine components, requires cutting tools with high wear resistance and machining accuracy. The toothed structure can maintain the quality of the cutting edge by replacing the blade.
5. General equipment and hardware products industry
Processing of general mechanical equipment racks and bases: The support surface of the rack and the positioning groove of the base are milled with a three sided milling cutter to ensure installation accuracy.
The groove processing of hardware tools and standard parts, such as adjustment grooves on wrenches and fixtures, requires uniform size specifications and is suitable for batch processing with standardized toothed three sided milling cutters.
6. Application advantages of three sided milling cutters with embedded teeth
High efficiency: With a multi blade design (both cylindrical and end faces have blades), multiple surfaces can be milled simultaneously, improving machining efficiency.
Economy: The toothed structure allows for individual replacement of worn blades without the need to scrap the entire tool, reducing usage costs.
Strong adaptability: By selecting blades of different materials (such as high-speed steel, hard alloy), it can process various materials such as steel, cast iron, and non-ferrous metals.
