Carbide Milling Cutter Uses:
Carbide cutter is generally used for CNC machining centers, cnc engraving machine. Can also be installed on the ordinary milling machine processing some of the more difficult and not complex heat treatment materials.
1. Carbide cylindrical milling cutter: for horizontal milling machine processing plane. Knife teeth distributed in the circumference of the cutter, according to the tooth is divided into straight and spiral teeth two. According to the number of teeth and coarse teeth two teeth. Spiral teeth coarse teeth milling teeth less teeth, high strength teeth, chip space, suitable for rough processing; fine tooth cutter for finishing.
2. Carbide Milling Cutter: for vertical milling machine, face milling machine or gantry milling machine on the plane, the end and circumference are knife teeth, but also coarse and fine teeth of the points. Its structure has a monolithic, insert type and indexable type.
3. Carbide end mills: for processing trench and step surface, etc., the teeth in the circumference and the end of the face, the work can not be along the axial feed. When the end mill through the center of the end teeth, the axial feed.
4. Carbide three-edge cutter: for the processing of various trenches and stepped surface, its both sides and circumference are knife teeth.
5. Carbide angle cutter: for milling into a certain angle of the groove, a single angle and double angle cutter two.
6. Carbide saw blade cutter: for processing deep groove and cut off the workpiece, the circle has more teeth. In order to reduce the friction at the time of milling, the teeth on both sides of the 15 '~ 1 ° of the sub-deflection. In addition, there are keyway cutter, dovetail slot cutter, T-slot cutter and a variety of milling cutter and so on.
As the side milling (also known as milling), the radial depth of cut should be less than 10% of the cutter diameter, that ar <0.1D
As the face milling (also known as end milling), the radial depth of cut should be less than or equal to 90% of the cutter diameter, that ar ≤ 0.9D
The radial depth of groove is equal to the diameter of the cutter, ie ar = D
Slot milling is a traditional composite milling method (radial feed after radial feed) or ramp milling (axial radial feed at the same time).
If an axial cutting similar to "drilling" is required, the end teeth of the milling cutter must be centered.
If the hole is reused with interpolation, the depth of the hole is at most 75% of the length of the cutting edge. And if used as a solid material on the hole, the value should not exceed 0.5 ~ 1D.
When milling, the direction of rotation of the cutter is the same as the feed direction of the table. The tool is cut from the surface of the workpiece, where the chip thickness is greatest. Horizontal cutting force will produce a clamping force, its direction is toward the table.
It is important to confirm that there is no gap in the machine's lead screw. Often, the surface finish is smooth and the tool life is improved.
In reverse milling, the direction of rotation of the cutter is opposite to that of the table. So the cutting tool from the cutting layer thickness of zero cut, gradually increased to the maximum thickness of the cut. This method will, under certain conditions, cause the tool wear to be accelerated. Reverse milling is done when milling hot-rolled surface hardened steel and steel with surface oxide.
