Carbide Arc Tooth Cutter
Arc tooth cutter is a kind of milling cutter,so how to
choose milling cutter ?
The price of imported milling cutters is relatively expensive. The
price of a face milling cutter body with a diameter of 100mm may
exceed 600 US dollars, so it should be selected carefully to meet
the specific processing needs.
1. First, when choosing a milling cutter, consider its number of
teeth. For example, a coarse-tooth milling cutter with a diameter
of 100mm has only 6 teeth, while a fine-tooth milling cutter with a
diameter of 100mm can have 8 teeth. The size of the tooth pitch
will determine the number of teeth that participate in cutting at
the same time during milling, which affects the smoothness of
cutting and the requirements for the cutting rate of the machine
tool. Each milling cutter manufacturer has its own line of coarse
and fine face milling cutters.
2. Coarse-tooth milling cutters are mostly used for roughing because they have larger chip pockets. If the chip flute is not large enough, it will cause difficulty in chip rolling or increase the friction between the chip and the cutter body and the workpiece. At the same feed speed, the cutting load per tooth of the coarse-tooth milling cutter is larger than that of the dense-tooth milling cutter.
3. The depth of cut during fine milling is shallow, generally 0.25-0.64mm, the cutting load of each tooth is small (about 0.05-0.15mm), and the required power is not large. You can choose a dense-tooth milling cutter, and you can choose a smaller cutter. large feed. Since the metal removal rate is always limited in fine milling, it is okay to have a smaller chip flute for a fine-pitch milling cutter.
