Generally, how to find the central coordinates of the CNC machining center circle? How to find the coordinates in CNC processing is one of the problems faced by many new people who just contact with the CNC machining center processing. Today, we will introduce how to find the central coordinates of the circle in the processing center.
1. CNC machining center how to find the central coordinate of the circle
1) Put the percentage meter on the spindle and move to the center of the circle. Watch the table and manually turn around in the center of the axis, see the x,y pressure in the negative direction and then turn around slowly and know that the best three points are all in the same position. Of course, all the points of the bored hole are in one position! This slowly skilled after the fast.
2) Install a drill bit and point the tip of the knife at the center of the circle. Lift the Z axis, remove the knife, the table seat on the spindle (the blade position), the percentage table against the surface of the workpiece, and then you manually rotate the spindle, observe the percentage table, which direction pressure the meter more, you hand wheel to the negative direction, so slowly calibration.
3) now there is a coaxial deviation alignment device, as long as the instrument clip on the spindle, through the spindle rotation two circle lun circle, and a spindle movement, can show on the display spindle axis and workpiece axis deviation size between XY coordinates, according to the size of the spindle shake in the past, very convenient, two or three minutes, high accuracy, do not need technology. 2. Understand the machining center center coordinates
In order to describe the movement of the machine tool, simplify the programming method and ensure the interchangeability of the recorded data, the coordinate system and motion direction of the CNC machine tool have been standardized, and both ISO and China have formulated the naming standards. Machine Coordinate System is a right-angle coordinate system composed of X, Y, and Z axes that takes the machine tool origin O as the coordinate system origin and follows the right-handed Cartesian rectangular coordinate system. Machine tool coordinate system is the basic coordinate system used to determine the workpiece coordinate system. Is the inherent coordinate system on the machine tool, and is equipped with a fixed coordinate origin.
