The CNC blade used in the CNC machining center is composed of two sets of cutters and collets. The cutting edge has a variety of turning tools for surface production and processing and twist drills, reamers, boring cutters, milling cutters and taps for hole production and processing. The collets should consider the full-automatic loosening and tightening of the lathe spindle and accurate positioning, It can accurately install all kinds of CNC tools and integrate the clamping of tool changing manipulator. In this article, we present some commonly used milling cutters for CNC machining. Available in many shapes and sizes, these milling cutters used in several milling machines, play a vital role in the process.
1. Slab Milling
Slab milling cutter is the most common turning tool in CNC machining center. It is widely used to produce and process plan parts. In addition to cutting with its end edge, the slab milling cutter also commonly cuts with its side edge. Sometimes, the end edge and side edge carry out cutting separately. The slab milling cutter can also be called cylinder turning tool.
2. End Milling Cutter
End milling cutter is the most common turning tool in CNC machining center. There are often drilling edges on the cylinder surface and end surface of the end milling cutter in NC machining center, the drilling shot on the cylinder surface 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, which can improve the unit root inspection of NC machine tool drilling, Improve the production and processing precision of CNC machining. Because there is no drilling edge at the inner hole management center of the general end milling cutter, the end milling cutter can not be used for radial cutting. The inner hole edge is mainly used to produce and process the bottom plan perpendicular to the side.
3. Keyway Milling Cutter
The keyway milling cutter has two side edges. The circular and inner holes often have drilling edges. The inner hole edge is added to the management center, which plays the role of end milling cutter and twist drill. During the production and processing of the gantry machining center, the radial cutting exceeds the groove depth, and then the total length of the groove is milled along the direction of the groove. The drilling edge on the circle of the keyway milling cutter is damaged only within a short distance close to the inner hole. During regrinding, only the drilling edge of the inner hole needs to be cut off, so the turning tool diameter will not change after regrinding.
4. Face Mill Cutter
It is formed by the development trend of end mill cutter. It is suitable for the production and processing of three-dimensional grinding tool concave die or convex concave die forming surface hole in CNC machining center. Sometimes it is also used for the connection production and processing with large connecting concave circle on plan parts. The tool 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 cutter and conical ball end mill cutter. The handle has straight handle, flattened straight handle and Morse taper handle. The structural characteristic of CNC machine tool is that the ball head or end surface is covered with drilling edges, and the round upper edge is connected with the ball head edge in a circular solitary way, which can do axial and radial cutting.
