Alloy tool - Alloy tool installation: When the alloy tool is installed, the firm bolts should be tightened successively and evenly. However, the bolt should not be screwed too tight, otherwise it will lead to the lathe tool placement prohibition. The length of the tool head extending out of the tool holder should only be small, extending out of the permanent period (L) 2H), it will cause the alloy tool vibration, thereby destroying the alloy sheet, in addition, it will also reduce the cutting amount. When the outer circle is turned, the placement of the tool and the tool tip should be the center line, at least not higher than the diameter of the workpiece 0. 01 mm, and when boring, should be accurate to the center. When placing the turning tool, it is better to use a thick pad than several thin pads, because the pad is not dense between the pads, vibration will occur during the processing, resulting in the collapse of the carbide sheet. When turning cast iron and bronze, the tip of the tool should be the median line, at least not higher than the diameter of the workpiece 0. 01 houm, and when boring, should be accurate to the center. When placing the turning tool, it is better to use a thick pad than several thin pads, because the pad is not dense between the pads, vibration will occur during the processing, resulting in the collapse of the carbide sheet. When turning cast iron, bronze and brass, the tip should be the Central Line, and when turning steel, it can be slightly higher than the Central Line 1 to 2 mm. The deflection of the spindle of the machine tool should not exceed 0 when processing steel parts. 05 mm, and when processing cast iron and other materials, should not exceed 0.10 mm.
