What CNC milling cutters are commonly used in machining centers? CNC machining center adopts a CNC insert which consists of two parts: cutter and collet. The cutting edge has all kinds of turning tools for production and processing, twist drill, reamer, boring cutter, milling cutter, and tap, etc. the automatic loosening and tightening of lathe spindle should be considered for the collet, which can accurately install all kinds of CNC tools and clamp integrated into the tool changing manipulator Wait.
1. Endmill
This end mill is the most common turning tool in the CNC machining center. There are drilling edges on the cylinder surface and end surface of the end milling cutter in the CNC machining center. The drilling ball on the surface of the cylinder dominates the drilling edge, the drilling edge on the end surface is the auxiliary drilling edge, and the main drilling edge is generally spiral teeth. In this way, it can improve the unit root inspection of CNC machine tools and enhance the production and processing of CNC machining center Precision. Because there is no cutting edge at the inner hole management center of the end mill, the end mill can not be used for radial cutting. The key of the inner hole edge is to produce and process the bottom plan which is vertical to the side.
2. Keyway milling cutter
The keyway milling cutter has two side edges, and there are often drilling edges on the circle and the inner hole. The inner hole edge is added to the management center, which has the functions of the end mill and twist drill. During the production and processing of the gantry machining center, the radial cutting tool exceeds the groove depth-first, and then the total length of the healthy groove is milled along the healthy groove direction. The round cutting edge of the keyway milling cutter is damaged only in a short distance close to the inner hole. When regrinding, only the inner hole drilling edge needs to be cut off, so the diameter of the turning tool will not change after regrinding.
3. Abrasive turning tool
The turning tools for grinding tools of CNC machine tools are formed by the development trend of the end milling cutter. It is suitable for the production and processing of a three-dimensional grinding tool concave die or punches die forming a surface hole in the CNC machining center. Sometimes, it is also used for connecting production and processing with a large connecting concave arc on plane drawing parts. The turning tool can be divided into conical end milling cutter (cone half-angle A / 2 = 3,5,7, 10) There are three kinds of cylindrical ball end mill and conical ball head end mill. There are straight shank, flattened straight shank, and Morse taper shank. The structural characteristics of the CNC machine tool are that the ball head or end surface is covered with drilling edge, and the round upper edge is connected with the ball head edge in a circular arc, which can make axial and radial cutting tools.
