(1) using the dial indicator measuring device to locate this method, you must first use the dial indicator centering or positioning mandrel, the workpiece on the reference hole coordinates set out, and then according to the reference hole coordinates, The position of the spindle. It is characterized by high precision, more convenient operation.
(2) the use of test rods to locate the positioning of this method is characterized by good positioning accuracy is low, find time-consuming. But this positioning method can directly find the boring machine spindle and the starting hole of the coordinate position.
(3) the use of the hole of the boundary is positioning This method is characterized by separable box hole can be used for boring. The disadvantage is that the auxiliary time is longer.
(4) the use of model positioning positioning This method is characterized by simple model structure, without complex adjustments. But the template is easy to deform, and when the workpiece needs to be processed on several different faces of the hole system, the need for a few models, find and positioning accuracy is also low.
