The selection of cutting tools is a very important step in processing metal automotive parts, which directly affects the quality, efficiency, and tool life of Dalian automotive parts processing. Below will introduce some specifications for selecting cutting tools.

Firstly, the selection of cutting tools should be based on the characteristics and process requirements of the processed material. The hardness, heat resistance, cutting ability, and other properties of different materials are different, so it is necessary to choose suitable cutting tools. For example, for processing materials with high hardness, hard alloy cutting tools or evaporated plating cutting tools can be selected; For materials with good heat resistance during processing, high-speed steel tools or coated tools can be chosen.

Secondly, the selection of cutting tools should take into account the shape and size of the material being processed. If the shape of the processed material is complex or the size is small, it is necessary to choose suitable special shaped tools, such as ball head tools, chamfering tools, etc., to ensure the processing quality. Meanwhile, for the processing of large-sized parts, tools with larger diameters should be selected, which can improve processing efficiency and reduce tool wear.

Thirdly, the selection of cutting tools should be considered in conjunction with the processing method and equipment conditions. The main processing methods include turning, milling, drilling, etc. Different processing methods have different cutting principles and requirements. In terms of equipment conditions, including tool clamping form, spindle speed, feed rate, etc. Only by combining processing methods and equipment conditions can suitable cutting tools be selected.

Fourthly, the selection of cutting tools should take into account the accuracy requirements of the processing. For workpieces with high requirements, it is necessary to choose high-precision cutting tools to ensure that the parts meet the requirements and reduce the time and process of secondary processing.

Fifth, when selecting cutting tools, one should consider the batch size and cost of processing. For workpieces processed in large quantities, tools with good wear resistance and longer lifespan should be selected as much as possible to reduce the frequency and cost of tool replacement. At the same time, the price of the cutting tool should also be considered and products with higher cost-effectiveness should be selected.

Sixth, when selecting cutting tools, consideration should be given to the processing environment and safety requirements. In some machining processes with special environments, such as high temperature, high speed, heavy cutting, etc., it is necessary to choose tools that can adapt to these special conditions. In addition, attention should be paid to the safety performance of the cutting tools, selecting tools with protective devices, and complying with relevant safety operating procedures.

In summary, the specifications for selecting cutting tools include selecting based on the characteristics and process requirements of the processed material, considering the shape and size of the processed material, considering the processing method and equipment conditions, considering the accuracy requirements of processing, considering the batch size and cost of processing, and considering the environmental and safety requirements of processing. Only by selecting appropriate cutting tools according to specifications can machining quality, efficiency, and tool life be guaranteed.
