What requirements are required when loading a knife
The blade of a lathe should be as high as the center of the workpiece. 2. The tool clamping in the out section of the tool carrier should be short, as far as possible out of length is generally not more than 1.5 times the thickness of the tool rod, otherwise easy to make the tool rod stiffness decreases, cutting vibration can be created.
The gasket below the tool pole is required to be flat, and the number of the blades should be as small as possible (usually no more than 3) and aligned with the edge of the knife. The car knife should be on the left when it is mounted on the tool holder.
The tool tip points at the center of the workpiece. The cutter should be in the right Angle of work. 3, the knife must be secured with the tool holder. 4, the blade of a knife can't go too long. One, the blade should not be warmed up
According to experience, the outer circle of the fine car often holds the tool slightly higher than the center of the work. When the inside of the car is inside, it is often slightly lower than the center of the work. It is generally not more than 1% of the diameter of the workpiece, whether it is high or low. For the tool tip to be pointed at the center of the workpiece, the following method is used: The knife is made according to the top height of the stern seat. The tip of the blade is close to the center of the center, adjusting the height of the blade according to the height difference between the tip and center. When it is important to note that the tool let point slightly higher than the top centers 0.2 ~ 0.3 mm, then tighten screw, turning tool will be a little lower, so the height of the blade are basic consistent with the height of the top center.
Visual inspection before turning tool clamping tool rod and the work piece is vertical axis, position adjustment right after, tighten the rest screws by hand, and then use a special tool post wrench will before and after at least two alternate tighten the screw. When using the tool holder, do not allow the casing to be added in case the screw is damaged. After the tool is installed, it should also be inspected for the possibility of interference or collision on the lathe when the tool is in the working limit
