Drilling & Boring

Allied Machine & Engineering announces its newest online tool: the Boring Insert Selector. This resource saves valuable time by simplifying the boring insert selection process and ensures machinists are provided the correct boring insert for each job's unique details.

Absolute Machine Tools Inc., Lorain, Ohio, is marking its 30th year as a machine tool importer and distributor in North America.

Learn how to achieve good chip control when drilling with indexable drills. Effective chip control is the most important factor in indexable insert drilling operations and is essential for quality hole making. Poor chip evacuation can result in poor surface finish and can lead to tool breakage and damaged components.

Sunnen Products Co., St. Louis, acquired BTA Heller Inc., a U.S.-based manufacturer of deep-hole tooling and systems for primary hole generation.

With a new re-engineered design, the Seco Perfomax indexable insert drill delivers higher drilling parameters and longer tool life as well as exceptional chip control and evacuation.

One of the challenges when boring workpiece materials susceptible to workhardening is recognizing whether the prebored hole is already workhardened.

J.M. Sales-USA, Troy, Mich., is the representative in North America for Swiss Tool Systems AG, Bürglen, Switzerland, a modular boring system provider.

The structural steel industry is bracing for – and counting on – a huge increase in demand for structural steel products. The anticipated surge in demand arises from a renewed focus on improving the country's infrastructure, as well as a high level of private sector construction.

For the 10th episode of The CNC Chef, Bob Warfield of the CNCCookbook discusses the challenges presented when drilling deep holes. Among them: clearing the chips, getting coolant down deep, and holding tolerances on position, diameter and surface finish.

There were a lot of deep discussions about holemaking at UNISIG's recent open house and seminar series for magazine editors. UNISIG engineers explained different methods of deep-hole drilling, including gundrilling and BTA drilling, and provided an overview of the machines and related systems the company builds to perform these operations.

Drilling has long been the cornerstone of the machining process, consuming roughly 50 percent of all tools and creating 75 percent of all chips. So it comes as no surprise that shops interested in reducing costs and increasing productivity should look first toward the full optimization of their holemaking processes with today's advanced solid-carbide and indexable-insert drill technologies.

In connection with my canvassing efforts to best focus the boring tools topic scheduled for the January issue of Cutting Tool Engineering, I spoke with Harvey Patterson, product development engineer at Scientific Cutting Tools Inc., Simi Valley, Calif.
