The surface roughness and processing speed of CNC milled parts are determined by the machine. There are many types of milling cutters to choose from, but what do we mean by flying cutters? What is it for? Below we will lead everyone to the relevant knowledge of flying knife.
What is a CNC milling fly cutter?
Flying knife is a kind of metal cutting mainly used for milling machines. It is a single-point rotary tool, which is mainly used to cut large-area flat surface machining parts. The ordinary flying knife can be adjusted to cut aluminum with a diameter of up to 2 inches, and cut aluminum with a depth of 0.01 inches under this diameter. Rotating tools are very suitable for cutting, engraving, sanding, drilling and grinding.
What types of CNC milling flying cutters are there?
The design and manufacture of flying knives can meet the specifications of most industries. There are many types of flying knives, such as large-diameter flying knives, double-head flying knives that can realize rough and fine milling, and rotary cutting tools.
1. Large-diameter flying cutter: Use this cutter to mill large planes on the milling machine, and the effect is better. The disc is fixed on the shank with hexagon socket screws. The disc can improve the rigidity of the fly knife shank, prevent the vibration of the fly knife shank, and improve the quality of the processed surface.
2. Double cutter head flying cutter that can realize rough and fine milling: For the processing of parts with large allowance and high surface quality requirements after processing, especially for the processing of various types of cast iron parts, double cutter heads can be used Throwing knife.
3. Rotary cutting tool: used to quickly and easily cut all fabric types up to eight layers without changing the pattern.
What is the function of CNC milling flying cutter?
1. It can be used in CNC machining centers and manual milling machines. Flying cutters are usually used to remove a large amount of metal and level it.
2. The ordinary flying knife can be adjusted to cut aluminum with a diameter of up to 2 inches, and cut aluminum with a depth of 0.01 inches under this diameter.

Summarize
CNC milling flying cutter is a kind of tool used for milling. They have different types. When the cutter is set appropriately, it will produce a very flat surface. The cutting edge can cover a large surface in one pass. The maximum speed is the maximum value that the speed can reach under certain conditions. Normal speed, the highest speed should not exceed 1800 speed.
