Then rotate the cutter at high speed in the specified direction. in order to get the workpiece as desired

How many types of cut flowers are there and what are they?

End mills can be of various types depending on the milling characteristics. Which can be divided according to the shape of the end mill will get the job as follows

Ball End Mills

curved end mill Or Ball End Mills: The end of the end mill is rounded without a flat bottom. with a full radius equal to half the tool diameter

Radius End Mills

Radius End Mills : Used to add a specific radius to the work piece. or in finishing to remove sharp edges or burrs

Taper End Mills

Taper End Mills : Pencil End Mills And conical end mills are commonly used for producing slots, holes or side milling with a slope angle.

Aluminum End Mills

Aluminum End Mills : Aluminum alloy is one of the newer materials that is not easy to machine. Because the wood chips can stick to the groove and pack.

Chamfer Milling Cutter

Choosing a milling cutter, end mill (End Mill) ?

Before using the milling cutter must understand the number of biting teeth well In order to be able to choose the end mill that meets the needs of use. which can classify teeth bite as follows

  • 1 flute type : designed for use in drilling hard materials that use high-speed rotation to break loose chips.
  • 2 flute type : designed to have a wide chipbreaker area. To help release the material that has been bitten well. therefore suitable for milling soft materials
  • 3-flute type : has a wider cross-section, making it suitable for milling hard materials, including ferrous metals and general metal
  • Type with 4 teeth or more : Designed for milling work with a higher rpm. But there is a problem that chip discharge is not good. But the advantage of having more teeth helps to keep the skin details well.
