Kennametal introduced a new line of digital-ready fine boring tools that make precision adjustment effortless maximizing productivity, predictable and accurate boring. The eBore Fine Boring System consists of cutting units to cover a diameter range from 6 to 1020mm (0.236” to 40.157”) and an optional digital display that makes precision adjustments as simple as turning a screw and costly mistakes a thing of the past.
Marcus Paul, Global Product Manager, Kennametal said: “For many workpieces, the boring operation is often the final step, and a simple mistake can lead to scrapped parts. 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.”
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 contain a glass-scale that keeps track of boring bar movement. Simply snap it in place, turn the boring head’s adjustment screw by the desired amount.
With eBore, there is no need to remove the boring head from the spindle for adjustment nor to count graduations or take notes. The device shuts off automatically after 30 seconds and provides more than 5,000 adjustments between battery changes. In case the boring head is forgotten to removed before turning on the spindle, a ball and spring clamping mechanism releases the display automatically at 500 RPM, preventing potential injuries. Built on simplicity, the eBore system comes with Kennametal’s KM quick-change interface and can be easily adapted to HSK, PSC, KM4X, and steep taper spindles.
