Drill bit developments in bench drilling

摘要

No one in the drilling industry can dispute the facts that good hole quality faster penetration rates and longer tool life give higher productivity and more profitable rock excavation Sandvik's new CAPP Black Label generation of threaded button-hits for bench drilling is designed to make it easier to achieve these fundamentals. In the year 2000, Sandvik launched the industry's first generation of drill-hits ever to be guided all the way from the design engineer's imagination to the customer's worksite by a fully integrated computer-aided product processing (CAPP) system. Judging by sales volumes and a sharp rise in market share since that time, customers noticed the difference in CAPP drill-bits in no uncertain terms. Now, barely three years down the line, the company is set to demonstrate again how product development in Sandviken never stops. Having processed feedback from the field with the tenacity only a robot could sustain, the Sandvik CAPP system - itself now further developed - has fine-tuned the design of CAPP series drill-hits to give the customer more. "Together with new developments in Sandvik cemented-carbides and manufacturing technology," says marketing manager Anders von Post, "this has increased the performance of the latest generation of bits to the extent that a new label is warranted to distinguish the old from the new."
