CNC Router tool selection and cutting the amount of determination is completed in the human-computer interaction state, requiring programmers must grasp the tool selection and cutting the amount of the basic principles of determining, in the programming to fully consider the characteristics of CNC Router, the correct choice of cutting tools and cutting The CNC processing technology involves a wide range of applications, the characteristics and difficulties of its processing technology is still how high-speed, high efficiency and correct selection of CNC machine tools to produce a technical requirements in line with the technical requirements of CNC Router processes and procedures. CNC Router can greatly shorten the product manufacturing cycle, an effective solution to the mechanical products in the complex, sophisticated, single small batch, the shape of the variable parts processing.
In order to adapt to the high speed, high efficiency and high degree of automation of CNC machine tools, the tool is moving in the direction of standardization, generalization and modularization. It is divided into two categories: milling tool and hole cutting tool. In order to meet the high efficiency and special milling requirements, but also the development of a variety of special purpose special tool.
CNC Router tool holder structure is divided into modular and integral two. The modular tool system is a more advanced tooling system, and each tool holder can be assembled from a variety of serialized modules. For different processing parts and machine tools, take a different assembly program, access to a variety of knife handle series, thereby improving the adaptability and utilization of the handle.
The same time as the above-
The working part of the overall tool holder tool is integrated with the handle on the machine. This tool holder is less adaptable to the transformation of machine tools and parts. In order to adapt to the transformation of parts and machine tools, the user must reserve a variety of tool holders, so the lower utilization of the handle.
The same time as the above-
CNC Router tool holder and spindle hole with the cone with a 7:24 conical handle, and the use of the corresponding type of pull nails, combined with the machine tool spindle. Taper shank with no self-locking, tool change and so on. Knife handle commonly used specifications are 40, 45 and 50. At present, China is widely used in IS07388-1983.MAS403-1982. ANSI / ASME 135.50-1985, etc., should choose the choice of toolholder specifications and machine tool spindle, the robot to adapt. JT: said the use of international standards IS07388 processing center machine with a taper handle; followed by the corresponding number of ISO taper. BT: indicates the use of the Japanese standard MAS403 processing center machine with a taper handle; then the number of the corresponding ISO taper number. For high-speed cutting commonly used HSK series handle.
In order to improve the processing efficiency, as far as possible the use of high efficiency tool and handle. Selection of strong milling chuck handle, high clamping accuracy, can be used to hold the straight handle tool, because the retainer itself is a small self-locking lock, clamping force, can be used for strong milling; In the high-precision milling reaming work, but also through the rod clamping hole with the tool.
The same time as the above-
Selection of spring chuck handle, buckle elastic deformation of 1mm, the main clamping small size milling cutter, such as drill, cutter, reamer, taps and so on. Selection of modular tool system because of its high positioning accuracy, easy loading and unloading, connection rigidity, with good resistance to vibration, is currently used in a more type, it consists of the handle, the middle pole and the working head. Selection of rough boring can choose double-edged boring tool handle, can improve the processing efficiency, but also help reduce the cutting vibration; for large quantities, processing complex typical parts, should be used as far as possible composite tool. Although the composite tool and the handle price is more expensive, but in the CNC machine tools using composite tool processing, can focus on the process, the multi-channel process into a process, by a tool to complete, help to reduce the processing time and tooling times, Significantly improve production efficiency.
CNC Router CNC Router in various forms, different types of CNC Router in the composition of the differences, but there are many similarities. Numerical control vertical lift milling machine as an example to introduce its composition. Ⅺ saw 040A CNC vertical lift milling machine equipped with Ⅳ four 3MA CNC system, using all-digital AC servo drive. The machine consists of six main parts: the bed part, the milling part, the table part, the horizontal feed part, the elevator part, the cooling and lubrication part. Bed inside the layout is reasonable, with good rigidity, the base is equipped with four adjustment bolts, easy to adjust the level of the machine, cutting fluid tanker set in the machine seat inside.
