The recent acquisition by Sunnen of BTA Heller has created an interesting solution for shops seeking complete bore drilling-to-finishing capabilities.

As a result of the purchase, Sunnen, which claims to be the world’s largest vertically integrated manufacturer of honing systems for precision bore sizing and finishing, now adds BTA’s deep-hole tooling and systems for primary hole generation.
“We have developed various tools and systems to facilitate intricate, internal, profiled deep-hole drilling from 12.7 to 914.4 mm (0.5 to 36”) diameter,” says Mark Sollich, director of Sunnen’s BTA Heller division. “To combine forces with Sunnen and its bore geometry expertise creates a unique resource. No other company can provide a total bore solution from the creation of the primary hole to the final bore finish specifications.”
In addition, as Sunnen enters the skiving/roller burnishing sector, the company brings its approach of providing support to customers using non-Sunnen equipment for bore creation and finishing, a key advantage for shops with a variety of machine types and/or manufacturers.
“Our companies complement each other very well,” says Chris Miltenberger, president and COO of Sunnen. “No other deep-hole/BTA company has Sunnen’s global presence for customer, technical and post-sales support. The transfer of knowledge between the two companies will create a unique value proposition, and Sunnen’s financial stability and strong sales and service network will deliver this expertise to our customers.”

Walter Ewag UK, a member of the United Grinding Group, reports that a number of machines from the Walter Helitronic tool grinding/erosion and Walter Helicheck tool measurement machine range, as well as Ewag’s Laser Line Precision insert production machine, will be on view at AMB (18-22 September, Stuttgart).

Visitors to AMB will, therefore, have the opportunity to see for themselves the build quality of these machines and, of course, investigate the numerous technology features available to help improve productivity and quality levels in terms of both
tool manufacturing and regrinding, as well as tool inspection and insert production using a laser.
From the Walter Helitronic range of multi-axis tool grinding/erosion and re-grinders, on show will be the two-in-one Power Diamond 400 grinding/erosion machine with robot loader – for the production of PCD as well as carbide tooling – and the Power 400 tool grinder/re-grinder with robot loader.
Both machines can accommodate tools of 3 to 315 mm diameter and up to 380 mm long, and in addition to having a grinding wheel/electrode changer (four-station as standard; eight-station optional) for increased automation and unmanned operation, both can utilise a range of robot loading solutions.
Walter’s Tool Studio 3 software will also be available, and this has integrated wizard technology for fast tool production simulation, parameter changes and machine operation – including an erosion function option for the fast and easy programming of ‘what you see you can grind and erode’.
Complementing these will be the Walter Helicheck Plus tool measurement machine with robot loader and the Helicheck 3D.
