Profile machining is a CNC machine tool with a tool library and the ability to actively replace tools, allowing for multiple processing operations on workpieces within a certain range. The characteristic of profile machining parts is that after being clamped once, the CNC system can control the machine tool to actively select and replace cutting tools according to different processes; Actively change the spindle speed, feed rate, and tool relative motion trajectory of the machine tool to the workpiece, as well as other auxiliary functions, and continuously carry out multi process processing such as drilling, spot faceting, reaming, boring, threading, and milling on each processing surface of the workpiece.
Due to the ability of the machining center to complete multiple processes in a centralized and proactive manner, it avoids human operational errors, reduces the time for workpiece clamping, measurement, and machine tool adjustment, as well as the time for workpiece turnover, transfer, and storage. This greatly improves the power and accuracy of precision turning, resulting in outstanding economic benefits. Profile machining can be divided into vertical machining centers and horizontal machining centers based on the position of the spindle in space.
Profile machining is a CNC boring and milling machine that combines the functions of CNC milling machines, CNC boring machines, and CNC drilling machines, and is equipped with a tool library and an active tool changing device. The spindle axis (z-axis) of the profile machining center is straight, suitable for processing cover plate parts and various molds; The spindle axis (z-axis) of a horizontal machining center is horizontal and generally equipped with a large capacity chain tool magazine. The machine tool is equipped with an active indexing workbench or a dual workbench for easy loading and unloading of workpieces. It is suitable for active completion of multi face and multi process machining of workpieces after one clamping, and is mainly used for machining box type parts.
Due to the above-mentioned functions of the profile machining machine tool, the programming of CNC machining is more complicated than other CNC machine tools, including the determination of machining processes, selection of cutting tools, organization of machining routes, and programming of CNC machining programs.
