Reamers & Boring Tools

The CBN-tipped mini boring bars feature BX310 uncoated CBN grade that increases the grade's wear resistance when used at low to medium cutting speeds, making it perfect for machining small bores from as small as 2.8 millimeter (.110 inch) diameter of hardened steel parts.

These adaptable tools can effectively finish a variety of holes in a high-mix, low-volume environment.

The tool's CERATIZIT R84 fine boring indexable inserts feature a brand new reaming geometry specifically designed for exceptional hole finishing. The new positive geometry generates extremely low cutting forces and includes a new chip breaker that improves chip control. All of which allows for higher feed speeds while at the same time producing a better surface quality. Plus, the new inserts provide a much longer tool life as compared to their predecessors.

A video from ARCH Cutting Tools offers guidance for effective chip evacuation, the proper method of holding the boring bar, and how to select insert geometry based on the cutting conditions.

As the world's smallest digital fine boring tool with a peripheral cutting edge, the unbalanced 420 (410) series has a diameter range of 0.787 inches – 1.142 inches (20.00 millimeters – 29.00 millimeters). The 465 (464) boring heads offer automatic self-balancing and bore diameters from 1.142 inches – 8.071 inches (29.00 millimeters – 205.00 millimeters). These boring heads have a special design to minimize the residual imbalance produced by insert holder displacement.

Lessons in reaming are shared.

Rigibore's Zenith ActiveEdge adjusts automatically from your measurement data, ensuring perfect bores with zero downtime. ActiveEdge tools are micron accurate in diameter (0.001) (0.00004") so even the tightest of tolerances can be met effortlessly. Save money by increasing production and eliminating scrap, with ActiveEdge technology.

These new vibration-free tools provide finish machining of precise bores (IT6–IT8) up to 6 × D, with high surface quality and are up to three times more reliable and flexible than comparable models. Their flexibility is boosted by the fact that the new Walter boring tools employ modular components such as cartridge holders and extensions, which are matched to the system, utilize an extensive range of indexable inserts suited for precision boring, and can be used for all material groups.

The future of boring is automated.

Posted as a supplement to "The Zenith of Boring," a feature article appearing in the July 2022 issue of Cutting Tool Engineering magazine, this video demonstrates how Rigibore's Zenith system integrates ActiveEdge tools with in-process gauging to enable a machine controller to automatically compensate for insert wear, temperature changes and material inconsistency without manual intervention and without manufacturing interruptions.
