Laser scanners and structured white light scanners for metrology are advancing at the same time that customer are demanding major improvements. As a result, scanning technologies are making rapid progress.
Holemaking in steel and cast iron up to one inch in diameter is one of the most widely used metalworking processes. What is driving drilling and tapping performance are advances in substrate, coatings, three-flute designs, and combination tools. Just as important are advances in coolant delivery, using different size holes and shapes to facilitate chip evacuation.
Today’s deep hole drilling systems control coolant much the same as they would a machine’s spindle or axes. Careful management of coolant pressure, filtration, temperature and flow rate is key to optimizing deep hole drilling.
Selecting the best type of cutting tool for holemaking jobs is not always clear. It is best to have a drill that caters to the workpiece material, produces the specs required, and provides the most profit for the job at hand. Considering the variety of jobs and parts manufactured in machine shops, there is no “one-drill-fits-all.”
