How does the CNC lathe drill center to detail?
First use the center drill, the first smooth, the second pull, the Dutch, and the drill to the center of the workpiece drilling a small hole! The center drill is a CNC machining center tool used for drilling end faces, in the center, CNC drill hole clamping workpiece in NC lathe lathe, and then it will be used in drill hole slowly close to this method can be used to do, this method is much higher than the first kind of precision tool.
See the center of the workpiece directly with the naked eye. The spindle stays still and then lets the drill close
That is, there are other tools on the lathe, such as cylindrical lathe tool, on the basis of other round turning tools, the outer surface of the cylinder to maintain XThe direction is constant, Z direction retract, then take a look at this knife, X direction of the mechanical coordinates of X1 (must be mechanical coordinates),The X value of the excircle tool you use to measure the caliper is X2 (diameter value), and the mechanical sitting of the drill bit in the center of the workpiece is calculatedStandard calculation method: X=X1-X2/2, and then the mechanical knife drill bit moving coordinate value in the way of using the handwheel, tool cutting tool number in direct input bit 0, and then click on the soft keyboard "measurement", so as to better.
If the drill, on center is not very high, generally to come to the center point can drill bottom.If it is a center drill or hard alloy drill, the requirement is higher. At this point, the center height of the machine tool holder must be right, the center height is not right, and you are not to the center position
