Фреза из быстрорежущей стали

The core function of the HSS milling cutter is milling metallic materials, and its core role is to achieve efficient and precise cutting-off, grooving or surface machining.
Core Function and Role of Фреза из быстрорежущей стали: The core function of HSS milling cutter is the milling processing of metallic materials. Their primary role is to achieve efficient and precise cutting-off, slotting, or surface machining.
Core Functions:
The fundamental function of an HSS milling cutter is to utilize the cutting edges on its periphery to perform rotary cutting, enabling the machining of narrow slots or cutting-off operations on a workpiece. This can be specifically categorized as follows:
1. Slotting: This is its most classic function. It involves milling straight slots of specific width and depth on a workpiece surface, such as keyways, relief grooves, or sealing grooves.
2. Cutting-Off/Parting: Used to separate elongated materials (e.g., bar stock, tubes) or finished components from the raw material.
3. Side Milling: Utilizes the sides of the peripheral cutting edges for small-area surface or shoulder milling.
4. Step Milling: Offers advantages over end mills when machining narrow and deep steps.
Product Characteristics:
These tools exhibit excellent wear resistance and high working efficiency. The machined slots exhibit precise widths and smooth walls. Their superiority is particularly evident when processing narrow slots. After heat treatment, they possess high red-hardness, maintaining stable hardness even in high-temperature environments exceeding 600°C.
1. Efficient Machining of Narrow Slots:
For narrow slots requiring precise widths (e.g., standard keyways), using a slitting saw matching the exact slot width allows for completion in a single pass. This efficiency is significantly higher than using small-diameter end mills for repeated milling. It ensures tolerance on slot width, parallelism, and surface finish of the side walls.
2. Excellent Economical Efficiency and Cost-Effectiveness:
The base cost of HSS material is lower than cemented carbide. Furthermore, HSS offers excellent regrindability. When the cutting edges wear, they can be easily resharpened multiple times on a tool grinder, restoring their sharpness. This significantly extends the tool’s total service life and reduces long-term machining costs.
3. Low Cutting Forces, Suitable for Standard Machine Tools:
Due to their thin-blade structure and the superior toughness of HSS compared to carbide, they generate relatively less vibration during cutting. This makes them less demanding on machine tool rigidity and power, rendering them highly suitable for use on older or conventional milling machines.
4. Good Toughness and Impact Resistance:
Under conditions involving intermittent cutting or minor impacts (e.g., milling shafts with existing keyways), HSS tools are less prone to chipping, offering an advantage over the more brittle cemented carbide.
5. Applicability to a Wide Range of Materials:
Although named “High-Speed Steel,” it is not limited to cutting steel. It is also widely used for machining narrow-deep slots or cutting-off in medium to low-strength metals like iron, aluminum, and copper, as well as for milling non-metallic materials such as plastics and wood.
Applications:
The product finds extensive application in industries including light industry, machinery, electronics, telecommunications, medical, hardware, automotive, and defense. It is highly regarded by users due to its well-balanced performance in efficiency, wear resistance, heat resistance, and toughness, coupled with its high cost-effectiveness. Conventional and complex non-standard custom products are available according to customer requirements.
