    Because the tools used in mechanical manufacturing are basically used for cutting metal materials, the term "cutting tool" is generally understood as metal cutting tools. The structure of various knives is made up of clamping part and working part. The clamping part and working part of the overall structure are all on the cutter body, and the working part of the inserted tooth structure cutter (knife tooth or blade) is mounted on the cutter body. The geometric parameters of the cutting part have great influence on the cutting efficiency and the machining quality. Increasing the rake angle can reduce the plastic deformation of the rake face when extruding the cutting layer, reduce the friction resistance of the chip flowing through the front, thereby reducing the cutting force and cutting heat. But increasing the rake angle will also reduce the strength of the cutting edge and reduce the heat dissipation volume of the cutter head.

    2、Measuring Element

    Front corner, back corner, width of cutting edge, edge defect, etc.


    To a certain extent, the accuracy of the tool determines the accuracy of the processed product. As machining requirements are getting higher and higher, the requirement and wear of cutting tools are more and more precise. Usually when the flank wear reaches 0.7 millimeters, the blade edge should be replaced; the maximum wear amount for finishing is 0.04 mm. With the development of industry, this demand is getting lower and lower. The corresponding measurement industry also needs to improve the accuracy and efficiency of testing instruments to meet the needs of the development of the machinery industry.


    With the development of the market, we have developed the VME series and the VMQ100 series to deal with the precision and efficiency of the tool set size measurement, and make up for the market defects of the size and damage of two machines. VME series, equipped with optical magnifying lens, high precision surface damage. Large field VMQ100 measuring instrument, equipped with liftable surface light, perfectly meets the detection clarity and detection efficiency brought by the wide range of tool edge angles.
