Three-sided cutter, can be divided into straight-tooth three-sided blade and wrong tooth three-sided blade. It is mainly used in the horizontal milling machine step surface and one or both ends through the shallow groove. In addition to the three-sided edge cutter with the main cutting edge, the two sides also have deputy cutting edge, thereby improving the cutting conditions, improve the cutting efficiency and reduce the surface roughness value. However, after resharpening the width of the larger changes, three-sided inserts cutter can solve this problem.
Integral thread cutter with chamfer function

The overall thread milling cutter with chamfer function is similar in structure to the general one-piece thread milling cutter but has a special chamfering edge at the root of the cutting edge for machining the thread end chamfer while machining the thread. Machining chamfering in 3 ways, when the tool diameter is large enough, chamfer edge can be used directly out of chamfering, the method is limited to the processing of female thread chamfering. When the tool diameter is small, chamfering can be used to machine the chamfer by circular motion. However, the use of chamfer cutting edge chamfer cutting edge, pay attention to the thread cutting tool and the thread should have a certain gap, in order to avoid interference phenomenon. If the machined thread depth is less than the effective cutting length of the tool, the tool will not be able to achieve the chamfer function, so choose the tool should ensure that the effective cutting length and thread depth match each other.
CNC milling machine end processing

In full-function CNC machine tools, the CNC system has the tool compensation function, which can be programmed according to the workpiece contour size. After the tool compensation is established and the tool compensation is executed, the CNC system automatically calculates the tool position and automatically adjusts the tool path to the tool path. Directly use the workpiece size preparation of processing procedures, tool wear, change the processing procedures unchanged, so the use of simple and convenient.
Economical CNC machine tools are simple in structure and low in price, and have a certain amount of possession in manufacturing enterprises. In economical CNC machine tool system, if there is no tool compensation function, the machining program can only be programmed according to the locus of the locus of the tool. This requires that the locus size of the tool locus should be calculated according to the workpiece contour size and tool diameter. Therefore, the calculation is large and complex, and the tool wear and tear, replace the need to recalculate the tool path locus size, re-programmed processing.
