Do you know the most commonly used milling cutters in machining?
Tungsten steel milling cutter is a kind of tool made of tungsten steel (tungsten carbide)，which is made through various processing procedures through carbide rods provided by Zhuzhou Our Precision Carbide Co., Ltd.
For this multi-tooth rotary tool, each tool is equivalent to a turning tool fixed on the rotating surface of the milling cutter. There are many types of milling cutters, with different structures, and a wide range of applications. According to their uses, they can be divided into three categories: plane milling cutters, groove milling cutters, and surface milling cutters.
The general specifications of milling cutters have been standardized, and several commonly used milling cutters are introduced below.
1.End mill
This type is the most commonly used milling cutter in CNC milling. The cutting edge on the cylindrical surface of the end milling is the main cutting edge, and the secondary cutting edge is distributed on the end surface. The main cutting edge is generally helical teeth, which can increase the cutting stability and improve the machining accuracy.
Since there is no cutting edge at the center of the end face of ordinary end milling cutters, the end mill cannot be used for axial feed when working. The end face blade is mainly used to process the bottom plane perpendicular to the side surface.
Application: used for processing grooves, stepped surfaces and forming surfaces using master molds.
2. Side milling cutter
Three-edge milling cutter can be divided into straight-tooth three-face and staggered-tooth three-face.
In addition to the main cutting edge on the circumference of the tri-face milling cutter, there are also secondary cutting edges on both sides, thereby improving the cutting conditions, increasing the cutting efficiency, and reducing the surface roughness value. However, the width dimension changes greatly after regrinding, and the toothed face milling cutter can solve this problem.
Application: machining of step surfaces and shallow grooves through one or two ends on a horizontal milling machine.
3.Face milling cutter
The main cutting edge is distributed on the cylindrical or conical surface, the end cutting edge is the secondary cutting edge, and the axis of the face mill is perpendicular to the processed surface. The face milling with an entering angle of 90° can mill a stepped surface with a wider bottom.
The face-milling cutter is used to process the plane, and at the same time, there are more teeth participating in the cutting, and the trimming effect of the secondary cutting edge, so that the surface roughness value of the machined surface is small, so a larger cutting amount can be used, the productivity is higher, and the application is wide.
Application : used in vertical milling machine or horizontal milling machine processing step surface and plane, especially suitable for processing larger plane.
4. Thread milling cutter
Compared with traditional thread processing methods, Carbide thread milling has great advantages in processing accuracy and processing efficiency, it's not restricted by thread structure and thread rotation during processing, and it's extremely convenient to adjust the size of thread diameter.
Thread milling uses the three-axis linkage function of the CNC machining center and the G02 or G03 spiral interpolation command to complete the thread milling work.
Thread milling cutter, as an advanced tool that has been developing rapidly in recent years, is becoming more and more widely accepted by enterprises and exhibits excellent and extraordinary processing performance. It has become a powerful tool for enterprises to reduce thread processing costs and improve efficiency.
Application: used in mold manufacturing; non-rotating or asymmetric parts; large boring diameter and interrupted cutting.
