Drilling & Boring

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.

Chamfers and countersinks help control burr formation, improve thread starts, and protect hole quality. This guide explains where each operation fits and how tooling choices affect results.

Walter has unveiled the Walter Cut G1221-P, an innovative grooving boring bar with precision cooling, for recessing and internal grooving. This monoblock boring bar has two coolant holes.

At Mitsubishi Hitachi Power Systems Americas Inc., holemaking success is about timing—finding the best sequence in which to perform manufacturing operations.

How do you treat your a customer who received an order and has a problem with it? Maybe you shipped the wrong part or made a part according to an old revision. How do you handle the situation and appease the customer?

The new Spade Drills from YG-1 are intended for a wide range of applications and raw materials such as steels, stainless steel, cast irons and so on. The indexable drill offer a wide range of diameters: from 9.5mm to 114.3mm.

Just in time (JIT) manufacturing, by nature, increases setups and shrinks batch sizes. This puts shops in a bind, because more setups and smaller batches are typically less profitable; but saying "no" to work can be even more painful.

Drilling, reaming and boring are the basic holemaking operations of machining. In simple terms, drilling creates a hole in a workpiece where there was no existing hole. Reaming and boring accurately enlarge holes that already exist.

Techniks Industries, Indianapolis, in April announced it had acquired the tooling assets of Parlec Inc., a Rochester, N.Y., company. With the acquisition, Techniks expands its broad product offering of aftermarket machine tool accessories, and greatly enhances its manufacturing and distribution capabilities to distributors and OEMs located throughout North America, according to a company news release.

Parker Steel Company, Maumee, Ohio, a supplier of metric-sized metals in North America, in March moved its headquarters from Toledo to Maumee. The company still maintains its two Toledo-based warehouses in the same locations.

Seco Tools LLC, Troy, Mich., in March expanded its service and support team with the addition of Olivier Branget to its North American Applications Engineering group and the promotion of Aaron Eller to Product Manager, ISO Turning and Advanced Materials.
