Unique Drill-to-Finish Bore Solution


Sunnen Products Company’s acquisition of BTA Heller Incorporated has created a unique solution for shops looking for complete bore drilling-to-finishing capabilities. Sunnen, the world's largest vertically integrated manufacturer of honing systems for precision bore sizing and finishing, adds BTA’s deep hole tooling and systems for primary hole generation as the companies build on natural synergies to offer single-source bore creation and finishing solutions. These new solutions will be on display at IMTS booths 237400 (Sunnen Products Company) and 432216 (BTA Heller).


Sunnen’s core technical competencies include automated and manual honing systems, custom system development and integration, abrasives, tooling, cutting fluids and gaging. The acquisition expands Sunnen’s industry leading honing expertise to include tooling for initial hole creation and other complementary bore sizing and finishing processes such as trepanning, counterboring and form boring. The BTA Heller product mix includes accessories for those processes including pressure heads, vibration dampeners and boring bars. Sunnen recently introduced the new SHD series skiving and roller burnishing system with tooling engineered and supplied by BTA Heller.  Sunnen will also be entering the market with a deep hole drilling and boring machine with tooling engineered and supplied by BTA Heller. 


As Sunnen enters the skiving/roller burnishing sector, it brings its unique approach of providing support to customers also using non-Sunnen equipment, a key advantage to shops using a variety of machine types and/or manufacturers for bore creation and finishing.
