The processing of stop holes in deep small-diameter holes and the burr issues of cross holes can be collectively resolved with fine hole discharge machining.
Many cutting tools now feature center holes for supplying cutting oil, as well as oil-through holes that run from the center hole toward the cutting edge. The center holes of increasingly miniaturized tools are becoming narrower and deeper. Fine hole electrical discharge machining excels at non-contact processing of small-diameter deep holes, allowing for the processing of center holes and the reduction of deburring processes at the cross sections of oil-through holes leading to the cutting edge through burr-free machining via discharge. Additionally, options specialized for processing the oil-through holes of miniaturized cutting tools, such as through detection and depth specification machining, are also being developed.
