Flat Bottom Corn Milling Cutter

Zhongyeda high quality Flat Bottom Corn Milling Cutter is a common type of corn milling cutter. The following is a detailed introduction:

Structural features

Shape of the cutter body: The overall shape is cylindrical, and the end is a flat-bottom design, which enables it to flatten the bottom surface of the workpiece during milling, ensuring the flatness and accuracy after processing.

Blade arrangement: The blades are arranged in a spiral shape on the cutter body, like corn kernels on a corn cob. The carbide blades on the adjacent rows of spiral teeth are both offset and overlapped4. This arrangement enables the tool to form a continuous cutting edge during the cutting process, with good chip separation performance, large chip space, and chips are not easy to clog4.

Chip groove: Usually equipped with a larger spiral chip groove, the number varies depending on the tool specifications, usually 4 to 824. The chip groove cooperates with the spiral arrangement of the blade to allow the chips to quickly discharge the cutting area, avoiding chip accumulation that affects the processing quality and tool life.

Material characteristics

Carbide material: Most flat-bottom corn milling cutters are made of carbide, which has extremely high hardness, good wear resistance and heat resistance. It can keep the cutting edge sharp under high-speed cutting and large cutting volume conditions, reduce tool wear, improve processing efficiency and quality, and is suitable for processing various materials with higher hardness.

Coating treatment: Some tools will be coated, such as TiN (titanium nitride), TiAlN (titanium aluminum nitride) and other coatings. The coating can further improve the hardness, lubricity and oxidation resistance of the tool, reduce cutting force, improve the surface quality of the processing, and extend the service life of the tool.

Performance advantages

Efficient cutting: The unique blade arrangement and large chip space enable it to achieve high-efficiency processing with large cutting depth, high metal removal rate, and can remove a large amount of material in a short time, improving processing efficiency.

Smooth cutting: The spiral blade arrangement makes the tool evenly stressed during cutting, with small vibration and smooth cutting process, which is conducive to improving processing accuracy and surface quality, reducing processing errors and surface roughness.

Good chip division and chip removal: The staggered arrangement of the blade and the spiral chip removal groove can effectively divide the chips into small segments and quickly discharge them, avoiding scratches on the processed surface and wear of the tool by the chips, ensuring smooth processing.

Application fields

Aerospace field: It is often used to process large parts such as aircraft engine blades and wing structural parts. It can perform efficient rough processing on difficult-to-process materials such as titanium alloys and aluminum alloys, and quickly remove the excess.

Mold manufacturing field: It is widely used in the rough processing of mold cavities. It can quickly mill out the approximate shape of the mold, leaving a margin for subsequent fine processing, and improving the efficiency of mold manufacturing.

Mechanical processing field: It can be used for rough processing of various mechanical parts, such as gear blanks, shaft parts, boxes, etc., and perform efficient milling processing on steel parts, cast iron and other materials, providing a good foundation for subsequent fine processing.

Composite material processing field: For composite materials such as carbon fiber and glass fiber, flat-bottomed corn milling cutters can also play a good processing performance, and can perform cutting, grooving and other processing operations on composite materials.
