The difference between machining center and CNC lathe
CNC machine tools:
Car,milling,planing,grinding,boring,drilling,electric sparking,shearing,bending,laser cutting,etc.are all mechanical processing methods.The so-called machining is to process metal blank parts into the required shape,including dimensional accuracy.And geometric precision in two ways.The equipment that can complete the above functions is called the machine tool,and the CNC machine tool is developed on the ordinary machine tool.The numerical control means digital control.
After the CNC system is installed on the machine tool,the machine tool becomes a CNC machine tool.Of course,the development of ordinary machine tools to CNC machine tools is not just a simple installation system.For example,from the development of milling machines to machining centers,the structure of machine tools has changed.The most important thing is to add a tool magazine,which greatly improves the accuracy.The main functions of the machining center are the functions of milling,boring and drilling.
The CNC equipment we generally refer to is mainly index-controlled machine tools and machining centers.
The machining center is a CNC machine tool that has a tool magazine and an automatic tool change function to perform multi-step machining on the workpiece once.The machining center is a highly mechatronic product.After the workpiece is clamped,the CNC system can control the machine tool to automatically select and replace tools according to different processes,automatically set the tool,automatically change the spindle speed,feed amount,etc.,and can continuously complete drilling,boring,Milling,reaming,tapping and other processes.Therefore,the workpiece clamping time,the auxiliary process time such as measurement and machine tool adjustment are greatly reduced,and the parts with complicated processing shape,high precision requirement,and frequent replacement of parts have good economic effects.
Machining centers are usually classified into horizontal,vertical and universal machining centers based on the relative positions of the main shaft and the table.
(1)Horizontal machining center:It refers to the machining center where the spindle axis and the worktable are arranged in parallel,which is mainly suitable for processing box-type parts.
(2)Vertical Machining Center:It refers to the machining center that is perpendicular to the spindle axis and the worktable.It is mainly used for processing complex parts such as plates,discs,molds and small shells.
(3)Universal machining center(also known as multi-axis linkage type machining center):It refers to the machining center that can control the linkage change by processing the angle between the spindle axis and the rotary axis of the table to complete the complex space surface machining.It is suitable for the machining of workpieces such as impeller rotors,molds and cutting tools with complex space surfaces.
