What is an End Mill or End Mill?
Milling cutters, also known as milling cutters or end mills, are tools that help in machining. There is a sharp tooth tip at the end of the tool. for forming each workpiece to have the desired shape both in terms of use or make it beautiful In the industry, there are many ways to create workpieces. Whether drilling holes using drill bits Threading by using taps or even slotting by milling cutters to form complex workpieces. But the forming of the workpiece depends on the shape. and the number of bits The way the end mill works is attached to the milling machine. 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
Square End Mills
Square End Mills : Square end mills are also called square end mills. "Flat end mills", with sharp-edged flutes cut at a 90° angle, are the most popular general purpose milling cutters.
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
Chamfer Milling Cutter : Used for chamfering such as 45°, 60°, 90°, 120° or top and bottom corners.
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.
