Kennametal Boring System Simplifies Precision Adjustment

Kennametal eBore fine boring system.

Kennametal’s eBore fine boring system is designed to eliminate boring operation mistakes that can lead to scrapped parts. The tools consist of cutting units for diameters ranging from 6 to 1,020 mm (0.236" to 40.157") and include an optional digital display that makes precision adjustments as simple as turning a screw. According to the company, these digital-ready fine boring tools enable more productive, predictable and accurate boring.

The company says the system is easy to use with a digital device, making it suitable for multiple types of tools and on various machines. 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. Simply 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. The system comes with Kennametal’s KM quick-change interface and can be easily adapted to HSK, PSC, KM4X and steep taper spindles.

The system does away with the need to remove the boring head from the spindle for adjustment, count graduations or take notes. It also eliminates concerns over backlash and movement due to overtightening of the boring head’s locking screw as well as test cuts and sneaking up on the bore. The result is less scrap and machine downtime as well as faster setups. The eBore line includes the eBore Universal Tool 6-152 mm (0.236"-5.984"); eBore Fine Boring Tool 20-205 mm (0.787"-8.071"), eBore Bridge Finishing Tool 200-1,020 mm (7.874"-40.157"); and eBore Twin Cutter Roughing Tool 19.5-1020mm (7.677"-40.157").
