Cemented carbide tool


Cemented carbide cutting tool is one of the widely used in metal cutting processing cutting tool. Will commonly used type of cemented carbide indexable insert, using laser processing, turning experiment was carried out in laboratories and processing surface roughness decreased, quality improvement, especially when turning stainless steel. A commonly used YT15, choice of test, YG6, YW1 three grades as the research object, each brand take four slices of the blade, using four types of different parameters for laser processing. Blade is quadrilateral, half edge laser processing, the other half edge to retain the original state, in order to compare the cutting test.

Cemented carbide tool

Turning tool rod materials generally using 45 steel, but for cutting knife, cutting knife, such as some of the tool rod, 40 cr is adopted, the heat treatment hardness of 35 ~ 45 HRC.
Tool rod cross section shapes are rectangle, square, and round three, most applications of rectangular cross section. When the cutter bar height is restricted, the square tool rod has a larger cross-sectional area, commonly used in automatic machine and CNC machine tool. Less round cutter bar used. Usually the section size of tool holder and the length can according to the center of cemented carbide toolselection high, see table. In general, tool rod hanging out cutter holder is approximately equal to the length of the tool rod 1-1.5 times as high as appropriate.
