Use of end mills

Face milling
End mills can be used for face milling. However, because its entering angle is 90°, the tool force is mainly radial force in addition to the main cutting force, which is easy to cause flexure and deformation of the tool bar, and also easy to cause vibration, which affects the processing efficiency. Therefore, except for the thin-bottomed workpiece Except for special reasons such as the need for small axial force or occasional reduction of tool inventory for face milling, it is not recommended to use end mills to machine flat surfaces without steps.

Side wall face milling
Most of the workpieces suitable for end milling have one or more sidewall surfaces perpendicular to the bottom surface (this surface is parallel to the milling machine spindle), which brings about a problem that is not in face milling: sidewall shape and accuracy problems .

Tungsten steel blade

Tungsten steel blades are made of tungsten steel. Tungsten steel is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy.

Tungsten steel has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500°C. It still has a high hardness at 1000°C.

Welded tungsten steel drill bit

The welded tungsten steel drill bit is made by smoothly welding a tungsten steel tooth crown on the steel drill body. This kind of drill bit adopts self-centering geometric edge type, with small cutting force, can achieve excellent chip control for most workpiece materials, and the processed hole has good surface finish, high dimensional accuracy and positioning accuracy. Perform subsequent finishing. The drill adopts an internal cooling system, which can be used in machining centers, CNC lathes or other high-rigidity, high-speed machine tools.
