How do you know the type of car knife
Pointed tool. A car knife characterized by a straight-line cutting knife is commonly referred to as a pointed car knife. This kind of lathe tool tip is composed of rectilinear Lord, vice cutting edges, machining parts, the part contour shape is mainly composed of a separate point or a straight line shape, resulting from the displacement of the main cutting edge and the other two kinds of cutting tool machining by the principle of parts contour shape is very different. Such as 90. Inside and outside the circular turning tool, the left and right side of the vehicle knife, cut off (car slot) the car knife and the blade of the tip of the knife the various outer circles and the inner hole tool.
A circular turning tool. It is a special numerical control machine tool. It is characterized by the shape of the edge of the blade of the main cutting edge, which is a small circular arc of error or line outline error; The edge of the arc blade is the tip of the blade of a circular turning tool, so it is not in the arc, but in the center of the arc. The circular radius of the lathe is not related to the shape of the parts, and can be determined according to the need for flexibility. This kind of tool can also be used as a kind of car knife when some sharp cutting tool or forming tool, such as a threading tool, has a certain circular arc shape. The circular curved tool can be used for turning the inside and outside of the car. It is especially suitable for turning all kinds of smooth connections (concave) forming surfaces
Forming tool. The shape and size of the shape and size of the cutting edge of the machine tool are the shape and size of the tool blade. In CNC turning, the common forming tool has small radius circular arc tool, non-rectangular slot machine tool and threading tool. In nc machining, it should be used as little or no forming tool. The choice of the turning tool of the machine clip Machine clip indexable nc tool common varieties, more than 2000 kinds of specifications, and requirements in a variety of indexable carbide insert, ceramic knives and other material of the blade to match. There are various kinds of milling cutter, hole cutting tool, lathe tool and compound cutter (drilling, expanding, boring, spot). In order to reduce the time and convenience of changing the knife, to facilitate the standardization of machine processing, the CNC turning process should be used as the machine clamp knife and blade. CNC lathe is used in the form of rotary tool.
