Diamond PCD/PCBN milling insert APMT1604/APMT1135 CNC insert
Specifications
CNC inserts are the general name for indexable turning inserts and are the mainstream products in modern metal cutting applications. Mainly used in metal turning, milling, cutting and grooving, thread turning and other fields.
CNC inserts are mainly used in metal turning, milling, cutting and grooving, thread turning and other fields. According to the material can be divided into coated blades, cermet blades, non-metallic ceramic blades, carbide blades, super hard blades and so on. It is characterized by high efficiency and high wear resistance, which is more than 4 times more efficient than traditional welding inserts and alloy inserts. With the continuous advancement of coating technology, breakthroughs in key technologies of wear resistance and high temperature resistance will further improve efficiency and reduce processing costs.
Numerical control machining (NC) refers to a process method for machining parts on NC machine tools. The process rules of NC machine tool machining and traditional machine tool machining are generally consistent, but there are also obvious changes. Machining method using digital information to control the displacement of parts and tools. It is an effective way to solve the problems of variable parts, small batch, complex shape, high precision and realize high efficiency and automatic processing.
Numerical control machining refers to, by the control system issued instructions to make the tool to meet the requirements of various movements, in the form of numbers and letters to express the shape and size of the workpiece and other technical requirements and processing technology requirements for processing. It generally refers to the process of parts processing on CNC machine tools.
Seriation, standardization tool used mostly on numerical control machine tool, clamp machine for indexable turning tool, such as facing tool shank and have national standards and series model of the cutting tools for machining center and automatic tool change device of machine tool, cutting tool shank for serialization and standardization of rules, such as taper shank tool system standard code for TSG - JT, The standard code of straight handle tool system is DSG-JZ. In addition, for the selected tool, before the use of the tool size is strictly measured to obtain accurate data, and the operator will input these data into the data system, through the program call and complete the processing process, so as to process qualified workpiece.
CNC turning tools commonly used generally divided into type turning tools, pointed turning tools, arc turning tools and three types. Forming turning tool is also called sample turning tool, the contour shape of its processing parts is completely determined by the shape and size of the turning tool blade. Numerical control turning processing, the common forming tool has small radius arc turning tool, non-rectangular slot tool and thread tool. In numerical control machining, should be used as little as possible or without forming turning tool. Pointed turning tool is characterized by straight cutting edge. This kind of tool tip is composed of straight main and auxiliary cutting edges, such as 900 inner and outer circle turning tool, left and right end face turning tool, grooving (cutting) turning tool and all kinds of outer circle and inner hole turning tool with very small chamfering tip. The selection method of geometric parameters (mainly geometric Angle) of sharp turning tool is basically the same as that of ordinary turning, but the characteristics of NC machining (such as machining route, machining interference, etc.) should be considered comprehensively, and the strength of the tool tip itself should be taken into account.
The second is the circular arc turning tool. The circular arc turning tool is characterized by a circular cutting edge with small roundness or line profile error. Each point of the arc edge of the turning tool is the tip of the circular arc turning tool, so the tool point is not on the arc, but on the center of the circle. Circular turning tool can be used for turning internal and external surface, especially suitable for turning various smooth connection (concave) forming surface. The radius of the arc should be less than or equal to the minimum radius of curvature on the concave contour of the parts, so as to avoid the occurrence of shallow processing. The radius should not be selected too small, otherwise it is not only difficult to manufacture, but also due to the weak strength of the tool tip or poor heat dissipation ability of the tool body and lead to tool damage.
