A corn cutter is a tool used to mill a groove or a high sidewall surface, typically with multiple flutes, named for its resemblance to a corn cob because of the multiple cutting edges (inserts) on each flute, as shown in Figure 4-3.
The cutter tooth structure of the corn milling cutter is divided into two types: the wrong tooth corn milling cutter and the full tooth corn milling cutter. Each of these is described below.
Wrong tooth structure hammering key knife
In a corn milling cutter with a staggered structure (see Fig. 4-4), there is a gap between two adjacent inserts on one flute, and this gap is completed by an insert on the other flute. There is a special reminder to the user of the corn milling cutter with the wrong tooth structure, that is, the two chip grooves of the corn milling cutter with the wrong tooth structure can only be used as one cutter tooth.
Full-tooth structure corn key knife
In the corn milling cutter with full tooth structure (see Figure 4-5), two adjacent cutter teeth on a chip groove overlap in the axial direction through the arrangement of spatial positions, so that the cutter teeth on such a chip groove can complete the task of one cutter tooth, and the axial position of the cutter teeth of the wrong tooth corn milling cutter and the full tooth corn milling cutter is shown in Figure 4-6.
Fig. 4-6a is a misaligned structure with a gap between two inserts (see the middle of the two red dotted lines in the diagram) that leaves a cutting task that needs to be performed by the inserts on the next flute:Similarly, there is a gap between the two inserts in this flute (see the middle of the two yellow dotted lines in the diagram), which leaves a cutting task that needs to be undertaken by the inserts on the next flute.Figure 4-6b shows a full-tooth structure with an axial overlap between the previous blade and the next blade (see the thick dotted green and purple lines on the figure). As a result, each flute of the full-tooth corn milling cutter can be used as a single tooth and is twice as efficient as the misalignment structure.
Switch the head to hit the meter milling cutter
Indexable corn milling cutters are available in a variety of forms, such as straight shanks (including flattened straight shanks), Morse taper shanks, sleeve types, modular shanks, 7:24 taper shanks, etc.The cutting force on the head of the corn milling cutter is very large, and it is relatively easy to be damaged. The head of the interchangeable corn cutter can be separated from the rear as a separate unit, and the cost of replacing it separately will be reduced if damaged.
Another benefit of the interchangeable head is that there are more forms of the head: basic right angles, large rounded corners and even ball heads are all possible options, so that the processing is more flexible.
