Kennametal’s (Pittsburgh, PA) eBore Fine Boring System is a line of digital-ready fine boring tools that make precision adjustment easy, enabling more productive, predictable, and accurate boring. Cutting units cover a diameter range from 6mm to 1020mm (0.236” to 40.157”), and an optional digital display makes precision adjustments as simple as turning a screw – no more costly mistakes.
“For many workpieces, the boring operation is often the final step, and a simple mistake can lead to scrapped parts,” said Global Product Manager Marcus Paul. “The Kennametal eBore fine boring system does away with the traditional ‘count the graduations’ approach to boring and reduces costly mistakes. We’ve found there’s tremendous operator acceptance due to its simplicity and ease- of-use. And because the same eBore digital device can be used across multiple types of tools and on various machines, it’s easy on the tooling budget as well.”
Offering no-mistake adjustments and accuracy to within 2 microns, Kennametal’s eBore digital device is an optional – though extremely useful – part of the Kennametal Digital Boring System
With Kennametal’s digital eBore digital device, dialing in a tight bore and losing count of how far the adjustment screw was turned is a thing of the past. With an adjustment accuracy of 0.002 mm (0.00008”), the chip and coolant-resistant device contains a glass-scale that keeps track of boring bar movement. Users snap it in place, turn the boring head’s adjustment screw by the desired amount, and the tool is ready for the next boring operation.
Users no long have to remove the boring head from the spindle for adjustment, count graduations, or take notes. eBore eliminates concerns over backlash and movement due to overtightening of the boring head’s locking screw –as well as endless test cuts and “sneaking up on the bore.” The result is less scrap, less downtime, and faster setups. The device shuts off automatically after 30 seconds and provides more than 5,000 adjustments between battery changes. And if an operator forgets to remove the boring head before turning on the spindle, a ball and spring clamping mechanism releases the display automatically at 500 RPM, preventing potential injuries.
