Lizhou Carbide End Mill Product Introduction
Carbide end milling cutter are a core product of Lizhou Carbide, precision-manufactured from carbide. Carbide is a powder metallurgy product, using micron-sized tungsten carbide, titanium carbide, and other high-hardness carbides as raw materials, combined with cobalt, nickel, and molybdenum binders, and sintered at high temperatures. They exhibit high hardness and outstanding wear resistance.
Lizhou offers a complete range of end mills, including solid carbide, straight shank, helical, end mills, and ball end mills. These are widely used in CNC machining centers and engraving machines, and are also suitable for conventional milling machines for machining hardened heat-treated workpieces.
The products feature two main improvements: balancing high wear resistance with high toughness to prevent tooth chipping and tool breakage when cutting hardened materials. The coated models use a high-toughness K-type carbide substrate, with the Impact Miracle coating series featuring grains finer than 1μm, offering both wear resistance and vibration reduction, suitable for high-intensity continuous machining, and superior durability and machining efficiency.
Carbide end mil use
Face Milling
End mills can be used for face milling. However, due to their 90° principal inclination angle, the tool is primarily subjected to radial forces, in addition to the main cutting force. This can easily lead to tool holder deformation and vibration, affecting machining efficiency. Therefore, except for workpieces with thin bottom surfaces, end mills are not recommended for machining flat surfaces without steps, unless there are special reasons requiring smaller axial forces or for subsurface milling to reduce tool inventory.
Side Wall Milling
Most workpieces suitable for end mill machining have one or more side wall surfaces perpendicular to the bottom surface (parallel to the milling machine spindle). This introduces problems not present in end milling: side wall shape and accuracy issues.
Solid carbide end mills
Solid carbide end mills are end mills made from a single piece of carbide bar. They are characterized by high hardness, wear resistance, heat resistance, good rigidity, and high machining accuracy. They are mainly used for grooving, cavitation, and finishing of molds, hardware, and precision parts, and are suitable for machining various materials such as steel, stainless steel, and aluminum alloys.
Flat-end milling cutter
A flat-end milling cutter is a type of end mill with a flat bottom and no rounded corners. It is mainly used for milling planes, slotting, creating steps, and clearing right angles. The bottom and side wall corners of the machined slots are 90° right angles. It is one of the most commonly used and basic cutting tools in CNC machining.
Round Nose End Mills
Round nose end mills (also called ball nose end mills) are end mills with a fixed rounded corner at the bottom. They are more wear-resistant and less prone to chipping than flat end mills, and are commonly used for milling grooves, cavities, and sidewalls, effectively removing imperfections and extending tool life. Lizhou round nose end mills are widely applicable, capable of machining most common metal materials such as steel, stainless steel, cast iron, aluminum alloys, copper, mold steel, and titanium alloys. As long as the correct coating and number of teeth are selected, they can be used for everything from general hardware to precision molds.
Ball End Mills
Ball end mills are end mills with a semi-circular (spherical) tip. They are mainly used for machining curved surfaces, arcs, mold cavities, and 3D shapes, producing smooth, curved contours. They are the most commonly used cutting tools for machining curved surfaces. Lizhou's ball end mills can machine different materials according to different coatings.
End mills with chip breakers
End mills with chip breakers are end mills with specially designed grooves on their helical cutting edges. During cutting, they automatically break long chips into short fragments, preventing them from getting tangled in the cutter or scratching the workpiece. Chip removal is also smoother, making them particularly suitable for machining materials that easily produce long chips, such as stainless steel, mild steel, and aluminum alloys.
