*Overall pre-harden first then fine processing ,avoid transformation when proceed twice
*Inspect the gap between insert and milling body with feeler gauge less than 0.02 .reduce the surface roughness and prolong tool's life
*Sub-zero treament to enhance tool's hardness ,toughness ,durability and reduce the residual internal stress

Selection of face milling cutters
The tools for machining flat workpieces are mainly face milling cutters, whose cutting edges are all over the circumference and end face. Among them, the cutting edge of the end face is a minor cutting edge. The diameter of the face milling cutter is relatively large, so the cutter teeth and the cutter body are usually separated when the cutter is selected to achieve the purpose of long-term use.
Choice of diameter
The choice of face milling cutter diameter is mainly divided into three situations:
(1) The surface area is not large. When selecting a tool, pay attention to selecting a tool or milling cutter with a larger diameter than the plane width, so that a single plane milling can be realized. When the width of the face milling cutter reaches 1.3 to 1.6 times the width of the processing surface, it can effectively ensure the better formation and discharge of chips.
(2) When the processing plane area is large, it is necessary to select a milling cutter with a suitable diameter to mill the plane multiple times. Among them, the diameter of the milling cutter will be limited due to the limitations of the machine tool, the depth and width of the cut, and the size of the insert and tool;
(3) When the machining plane is small and the workpieces are scattered, an end mill with a smaller diameter needs to be used for milling. In order to maximize the processing efficiency, 2/3 of the diameter of the milling cutter should be in contact with the workpiece, that is, the diameter of the milling cutter is equal to 1.5 times the milling width. When down milling, the rational use of the ratio of the tool diameter to the cutting width will ensure that the milling cutter has a very suitable angle when cutting the workpiece. If you are not sure if the machine has enough power to keep the cutter cutting at this ratio, you can divide the axial thickness of the cut in two or more times to keep the ratio of cutter diameter to cutting width as much as possible.
Choice of milling cutter teeth
When choosing a milling cutter for processing, the number of teeth of the milling cutter needs to be considered. For example, a coarse-tooth milling cutter with a diameter of 100mm has only 6 teeth, while a dense-tooth milling cutter with a diameter of 100mm can have 8 teeth. Whether the cutter teeth are dense or not will affect the production efficiency and product quality. If the cutter teeth are dense, the production efficiency will be improved, and the quality of the machined workpiece will be better, but the dense cutter teeth will also lead to inconvenient chip discharge. According to the diameter of the teeth, they can be divided into sparse teeth, fine teeth, and dense teeth.
The sparse tooth is used in the rough machining of the workpiece. It uses 1 to 1.5 blades per 25.4mm diameter, and has a large chip space. This tool is used for cutting soft materials that can generate continuous chips. Long blades and large widths are used for cutting. The dense tooth is good for machining under stable conditions. It is generally used for rough machining of cast iron, and is also suitable for shallow cutting, narrow cutting and cutting of high temperature alloys when no chip space is required. The dense tooth is used for fine milling, and its axial depth of cut is 0.25-0.64mm, the cutting load of each tooth is small, and the required power is not large, such as for the processing of thin-walled materials. The size of the tooth pitch will determine the number of teeth involved in cutting at the same time during milling. During cutting, at least one blade should be cutting to avoid milling impact, resulting in tool damage and overloading of the machine tool.
In addition, the number of teeth on the insert must be chosen so that the chips are properly curled and can easily leave the cutting zone. Improper chip space will lead to chip hold-up, damage to the cutting edge and possible damage to the workpiece. At the same time, the inserts should be dense enough to ensure that no less than one insert is cutting at any time during the cutting process. Failure to do so will cause severe impact, which will lead to cracking of the cutting edge, damage to the tool and the machine tool of overload.
