I. 6 Introduction to End Mills
6 End mills are primarily used for high-speed finishing of high-hardness materials. With six cutting edges and relatively limited chip evacuation space, they are not well suited for roughing operations or for machining soft materials like aluminum that tend to adhere to the tool; instead, they are ideally employed for side milling and finish face milling of hard metals such as stainless steel and quenched steel.
II. 6 Core Advantages and Features of End Mills
① Excellent surface finish
A greater number of cutting edges means that, at the same feed rate, the chip load per tooth is reduced, resulting in a mirror‑like finish.
② Higher feed rate
Under the same feed per tooth, 6 The overall feed rate of the cutting tool can be higher than 4 Blade or 2 Blade tools are much faster.
③ Greater tool rigidity
Because the center core is thicker, the tool is less prone to elastic deformation during high-speed cutting, resulting in higher machining accuracy.
④ Longer lifespan
The cutting load is evenly distributed across six inserts, thereby reducing the wear rate of each individual cutting edge.
III. 6 Material and Coating of End Mills
AITiN Coating: Suitable for machining stainless steel, alloy steel, HRC45-55 Steel components on both sides exhibit extremely high heat resistance.
NACo Coating (blue nano-coating): Suitable for machining HRC60-65 The aforementioned ultra-high-hardness quenched steels exhibit excellent hardness and red hardness.
Solid carbide body: All of Lizhou’s end mills are crafted from a solid carbide body, ensuring high rigidity while enabling high-speed cutting.
IV. Classification of Cemented Carbide Geometric Structures
① Unequal‑step cutting: Effectively suppresses cutting vibrations and is recommended for continuous machining under vibratory conditions, thereby further enhancing surface finish.
② Plain‑shank end mills: Used for right‑angle side milling, slotting, and finish machining of flat surfaces.
③ Ball head \ Corner-radius end mill: with R of the angle 6 Blade milling cutters are widely used in contouring and abrasive‑tool machining, and rounded corners help prevent chipping at sharp edges.
V. 6 Precautions for Using End Mills
You can pay attention from three aspects:
① Avoid deep groove machining
6 The chip flutes of the end mill are very narrow; deep machining can lead to chip clogging and tool breakage, and it also makes tool changes easier. Therefore, when using… 6 When using end mills, avoid machining deep grooves.
② Avoid machining aluminum alloys.
Aluminum alloys are highly machinable but tend to stick to the cutting tool; when machining aluminum alloys, use… 6 End mills can become clogged; aluminum alloys must be machined using… 2 Blade or 3 The cutting edge features a large chip evacuation groove; therefore, avoid using it when machining aluminum alloys. 6 End mill.
③ Avoid using tool holders with high stiffness.
It is recommended to use a heat‑shrink or hydraulic tool holder, as these minimize radial runout and thereby reduce the frequency of tool changes; therefore, avoid using high‑rigidity tool holders.
