Boring Head Tool Extension Achieves More Precise Holemaking

Holemaking and finishing cutting tools manufacturer Allied Machine and Engineering continues to expand the Wohlhaupter boring tool product line with the launch of the 420 (410) series fine boring heads, as well as the expansion of the 465 (464) series. Both the 420 (410) and 465 (464) digital boring heads are equipped with a 3ETech docking port for easy digital diameter adjustments. Holemaking is the most commonly performed of all machining operations, suitable for plastic injection molds or any other application where a deep reach is required.

Offered as one of the world’s smallest digital fine boring tool with a peripheral cutting edge, the unbalanced 420 (410) series has a diameter range of 0.787-1.142" (20-29 mm). The 465 (464) boring heads feature automatic self-balancing and bore diameters from 1.142-8.071" (29-205 mm). Their design minimizes the residual imbalance produced by insert holder displacement, according to the company. As a result, the tools remain stable even with light interrupted cuts throughout the entire machining process and reportedly achieve the tightest tolerances and optimum surface quality. Additionally, the insert holder can be rotated for reverse machining jobs.

The tools are available in a non-digital version with vernier-scale adjustment or in the digital version for adaptation with the 3ETech digital display for μ-accurate adjustment. Wohlhaupter’s 3ETech digital display module can now be used with all types of precision boring tools including fine boring with the 420 (410) and 465 (464) series, versatile boring with VarioBore, large-diameter boring with the 538 (537) finish boring cassettes and custom boring tool solutions. The digital display module is docked to the tool, enabling maximum coolant pressure to be used and eliminating the risk of damaging the digital components during operation. Users now only need a single display module for all tools with integrated 3ETech technology, which reduces tooling costs.
