ZXMT030203OO-E ZXMT030203GM-I GM-E GH-E SM-E GM-I : 1st Recommendation : 2nd Recommendation Chipbreaker Advantages Chipbreaker GM GH SM Insert D c Advantages 1st. recommendation for carbon steel and alloy steel, 1st. recommendation for cast iron. 1st. recommendation for interrupted machining and hard materials. Cutting edge strength oriented design. Suitable for sticky materials such as stainless steel and low carbon steel. Good balance of sharp cutting and cutting edge strength. Middle to high feed rates of steel machining, GM Chipbreaker alternative. Sharp cutting, prevents chattering. For low to medium feed rates of steel.

(Therefore, the cutting diameter is slightly bigger during cutting). Once cutting is finished, the holder will return back to normal size. No tool marks will appear on the finished surface. (Although this depends on workpiece and cutting condition: during external machining slight tool mark might appear.) Insert Wear When an insert is at the end of its tool life, Gradually the external corner part gets worn out, the holder does not bend slightly outwards - it starts to bend inwards. After the cutting is finished, the holder returns to the normal position. When taking off a holder under this condition the cutting edge of the insert creates external tool marks on the finished surface of the workpiece. Checking Cutting Diameter When cutting diameter is measured, suddenly it shows small diameter. In this case, a worn out insert can be the cause. Checking the Surface on the Exit Side If insert wear progresses, the burrs of penetrated hole entrance become bigger. This is a clear indication that the tool must be exchanged. Variation of Cutting Noise Light cutting noise at the beginning turns to vibration noise. Variation of Vibration As the end of tool life is getting closer, there is more vibration and the cutting noise changes. However, when machining smaller diameters these factors are difficult to detect.
