What are the tool setting methods for Dongguan turning and milling composite processing

The purpose of Dongguan turning and milling composite machining tool alignment is to determine the position of the program origin in the machine coordinate system. Simply put, setting the tool is to control the tool tip points of all the machine tools at the same point. The essence of tool alignment is to preliminarily determine a relative position between the tool and the workpiece, and according to this position, determine the next cutting position based on the size to be processed.

1. Trial cutting method for knife alignment

The trial cutting method belongs to the machine tool alignment method, which is simple to operate, widely used, and suitable for the vast majority of situations in lathes.

2. Knife setting block, knife setting

The tool setting block belongs to the manual tool setting in the machine, which is low-cost and fast. Without considering the accuracy of tool setting, its tool setting efficiency can be said to be the first.

The tool block alignment method is similar to the trial cutting method, except that the spindle does not rotate during tool alignment. A tool block (which can also be a feeler gauge or a standard mandrel) is added between the tool and the workpiece to ensure that the tool block cannot be freely moved.

3. Knife setting instrument knife setting

Tool setting instrument is an accessory product of CNC machine tools in the rapid development of modern technology. It is commonly used in CNC lathes, milling machines, and machining centers, which can be divided into two types: internal and several positions. Generally speaking, external tool setting instruments have more potential for development than internal tool setting instruments. Because the external tool setting instrument has a large number of tool settings. High efficiency and wide applicability. It will have a wide range of application prospects in the future.

The working principle of CNC machine tools determines that when the machine tool returns to the mechanical reference points of its respective motion axes, the machine coordinate system is established. Once this reference point is established, compared to the zero point of Dongguan turning and milling composite machining machine tool, the various motion directions on each axis of the machine coordinate system have practical numerical significance.
