How to find the rotary center of horizontal machining center
Adjust the workbench to the mechanical zero point, insert a standard inspection bar into the spindle, press it to the zero line at the highest point on the side of the inspection bar with a dial indicator, the dial indicator and the mechanical zero point will not move, the workbench will rotate by 65438+X0(0, write down the mechanical coordinate value of the X axis (denoted as X2, 2 as subscript), then make the spindle inspection bar leave the dial indicator and calculate (X 1+X2)/2 as.

Similarly, we can infer the mechanical coordinate value Z0 in the Z-axis direction (0 is a suffix character), and record X0 and Z0 to provide input data for the subsequent mathematical calculation (this is another complicated process).

Extended data:

CNC milling machine is a kind of CNC machine tool with powerful machining function. At present, the rapid development of machining centers and flexible machining units are based on CNC milling machines and CNC boring machines, both of which are inseparable from milling methods. Because the process of NC milling is the most complicated and there are the most technical problems to be solved, people have always focused on milling when researching and developing NC system software and automatic programming language.

With the rapid development of social production and science and technology, mechanical products are becoming more and more precise, and the requirements are frequently revised, especially in aerospace, shipbuilding, military and other fields, which require high precision, complex shape and small batch. Processing such products requires frequent modification or adjustment of equipment, and ordinary machine tools or highly specialized automated machine tools can no longer meet these requirements. In order to solve the above problems, a new type of machine tool-CNC machine tool came into being.

This new machine tool has the advantages of strong adaptability, high machining accuracy, stable machining quality and high production efficiency. It comprehensively applies many technical achievements such as computer, automatic control, servo drive, precision measurement and new mechanical structure, and is the development direction of CNC machine tools in the future.
