The choice of tool is the most important part of CNC machining. The choice of tool determines the machining efficiency of CNC lathe and determines the quality of CNC machining parts. How to choose CNC machining tools? The choice of tool depends on the geometry of the part being machined, the material state, the rigidity of the tool and the tool selected for the machine. Jiexiang CNC machining center tells you the following points.
1. Select the tool according to the cutting performance of the part material. For cars or milled high-strength steels, titanium alloys, and stainless steel parts, it is recommended to select indexable carbide tools with good wear resistance.
2. Select the tool according to the machining stage of the part. That is, the roughing stage is mainly to remove the margin. The tool with better rigidity and lower precision should be selected. The semi-finishing and finishing stages should be used to ensure the machining accuracy and product quality of the parts. The durability should be high and the precision should be selected. For high tools, the tools used in the roughing phase have the lowest precision and the tools used in the finishing phase have the highest precision.
If the same tool is selected for roughing and finishing, it is recommended to use the finishing tool to eliminate the roughing tool, because the tool wear condition of the finishing process is mostly the slight wear of the blade, the coating wears and repairs the light, and the continuous use will affect the CNC machining. The quality of the processing, but the impact on roughing is small.
3. Select the tool and geometry parameters according to the characteristics of the machining area. Tools with large diameter and long diameter ratio should be used when the structure of the part is allowed; the end mill edge of the thin-walled and ultra-thin wall parts should have sufficient centripetal angle to reduce the cutting of the tool and the cutting part. force. When processing parts of soft materials such as aluminum and copper, you should select an end mill with a slightly larger front corner, and the number of teeth should not exceed 4 teeth.
In order to have high processing efficiency and good quality of processed parts, we must first select the tools used in CNC machining centers. Dongguan Jiexiang Industrial Co., Ltd. mainly produces (processing custom to map custom) all kinds of precision metal parts, such as precision CNC machining, CNC metal processing, CNC lathe processing, metal stamping, plastic injection molding, mold processing.
