CNC cutting tool can be divided into two major categories. They are conventional cutting tools and modular cutting tool, and the modular cutting tool is the main development direction. The main advantage of the development of modular tool: reducing tool change downtime, improve production and processing time; accelerate tool change and installation time, improve the economy of small batch production; improve the degree of standardization and rationalization of the tool; improve management and flexible processing tool level; expand the utilization of the tool, give full play to the performance of the tool; effectively eliminate work interruptions tool measuring and presetting can be used outside the line. In fact, due to the modules of the development of the cutting tool, the CNC cutting tool has formed three systems, namely turning cutting tool system, the system of drilling cutting tools and boring and milling cutter system.
Features CNC Cutting Tools
In order to achieve the purpose of high efficiency, more able, quick-change and economic, and compared with ordinary metal cutting tools, the CNC cutting tools have the following characteristics: highly universal and standardized serialization of CNC blade and CNC tool holders; blade or tool durability and reasonable indicators of economic life; standardization of the geometric parameters of the tool or blade and cutting parameters typifying; blade or tool material and cutting parameters processing materials should match; tool should have a high accuracy, including the accuracy of the shape of the tool, the accuracy of the relative position of the blade and shank of the machine tool spindle, blade and hilt translocation and disassembly repeat accuracy; shank strength, rigidity and wear resistance is better; shank or tool installed weight limit; position and direction of the blade and shank cut requirements; basis of positioning of the blade, hilt and automatic tool changing system optimization. CNC cutting tools with the tool should meet and easy to install, good rigidity, high precision, and durability requirements.
Factors to Choose CNC Cutting Tool
The choice of the cutting tool is an important thing in the CNC machining process. Since it will not only affect the processing efficiency of the machine, but also it will directly affect the cutting quality. CNC cutting tool spindle speed and range far higher than the ordinary machine tool and spindle output power, compared with the traditional method of processing, CNC machining tool put forward higher requirements, including high-precision, high strength, rigidity good, high durability, and dimensionally stable and easy to install. This tool structure is reasonable, the geometric parameters of standardization, serialization requirements. CNC cutting tool is one of the prerequisites for improving the processing efficiency, and its selection depends on the geometry of the machined parts, material status, fixtures and machine tool sselection tool rigidity.
