How to choose a tool for aluminum alloy CNC machining?
A long time ago,processing a metal object was only possible by quenching and forging.With the development of technology,with lathe processing,and today's CNC lathe processing,metal processing has become easier.In the CNC machining process,the tool is the most important.The Jiexiang CNC machining center will introduce you to how to choose aluminum machining tools today.
1.For the machining of the peripheral contour of flat parts,end mills are often used.
2.When milling the plane,the carbide insert milling cutter should be selected.
3.When machining the bosses and grooves,select the high-speed steel end mill.
4.When machining the surface of the blank or roughing the hole,a corn milling cutter with a carbide insert can be selected.
5.For the machining of some three-dimensional and variable-angle contours,ball-end milling cutters,ring milling cutters,conical milling cutters and disc milling cutters are often used.
6.When performing free-form surface machining,since the cutting speed of the end of the ball-end tool is zero,in order to ensure the machining accuracy,the cutting line spacing is generally very dense,so the ball head is often used for surface finishing.
7.Flat-headed cutters are superior to ball-end knives in terms of surface quality and cutting efficiency.Therefore,as long as the roughing or finishing of the curved surface is ensured,the flat-blade knives should be preferred.
8.In the machining center,various tools are installed on the tool magazine,and the tool selection and tool change operations are performed at any time according to the program.Therefore,a standard tool holder must be used to quickly and accurately load the standard tool for drilling,boring,expanding,milling,etc.onto the machine tool spindle or tool magazine.The number of tools should be reduced as much as possible;after machining a tool,all the machining positions that can be carried out should be completed;the rough-finished tools should be used separately for even the same size specifications;first milling and then drilling;first surface finishing Perform 2D contour finishing;when possible,use the automatic tool change function of CNC machine tools to improve production efficiency.
The choice of tool is carried out in the human-computer interaction state of NC programming.The tool and tool holder should be selected correctly according to the machining capacity of the machine tool,the performance of the workpiece material,the machining process,the amount of cutting and other relevant factors.
The selection of aluminum alloy CNC machining tools needs to follow the general principle of tool selection:easy to install and adjust,good rigidity,high durability and high precision.Under the premise of meeting the processing requirements,try to choose a shorter tool holder to improve the rigidity of the tool processing.When selecting a tool,make the size of the tool match the surface size of the workpiece being machined.
