Number of workpieces touched by CNC machining center2020-06-11
For the clamped work piece, the touch head can be used to set the reference number of the touch number. The touch head can be used in both photoelectric and mechanical types. There are two kinds of methods: mid-touch and unilateral touch. The steps of mid-touch are as follows:
Photoelectric static, mechanical speed 450~600rpm. Move the X-axis of the worktable manually in the middle of the touch, so that the touch head touches the side of the workpiece. When the touch head just touches the workpiece and the red light is on, the relative coordinate value of this point is set to zero; then move the work manually The X axis of the stage makes the counter head touch the other side of the workpiece. When the counter head just touches the workpiece, the relative coordinates at this time are recorded.
According to the relative value minus the diameter of the touch head (ie the length of the workpiece), check whether the length of the workpiece meets the requirements of the drawing.
Divide this relative coordinate number by 2 and the resulting value is the intermediate value of the X axis of the workpiece. Then move the table to the intermediate value of the X axis. Set the relative coordinate value of the X axis at this point to zero, which is the workpiece The zero position on the X axis.
Carefully record the machine coordinate value of the zero position on the X axis of the workpiece in one of G54~G59, and let the machine tool determine the zero position on the X axis of the workpiece. Once again, carefully check the correctness of the data. The procedure for setting the zero position of the Y axis of the workpiece is the same as the operation of the X axis.
