Drilling & Boring

Three elements — cutting speed, stability and chip evacuation — can help shops achieve the lowest cost per hole.

The standard A2201 is an offset adaptor for reduced radial forces, greater stability and provides more space between the boring bar and the bore wall for improved chip removal with very deep bores. With the A3001 and the A2201 Walter has increased boring bar diameters to 2.5-4-in. and 60-100 mm.

Big Kaiser Precision Tooling Inc. plans to change its name to Big Daishowa Inc. effective Jan. 1.

Mitsui Seiki's J series combines the accuracy of a jig borer and the productivity of a machining center.n

At every stage of manufacturing, there is an opportunity for automation. Unfortunately, many manufactures often let perceived barriers keep them from implementing complete machine or process automation. With this mindset, they end up limiting their productivity by automating only one or two aspects of the process or not automating at all.

The 465 (464) fine boring heads have a full diameter range of 1.968" – 8.070" (50mm – 205mm) with the lightweight aluminum Alu-Line boring heads ranging from 2.559" – 8.070" (65.00mm – 205.00mm). Featuring the standard Wohlhaupter MVS connection, these boring heads provide the capability to adapt to any machine.

Effectively drilling austempered ductile iron requires a balanced approach.

Walter USA LLC has assumed governance of the round tool production unit in Greer, South Carolina, through an intra-company transfer within the Sandvik Group. Having a dedicated production facility in the U.S. will enable Walter to provide both better responsiveness to customer demand as well as improve supply chain security.

The CERATIZIT WTX-HFDS solid carbide drill with Dragonskin coating achieves new levels of quality, hole tolerance, and positioning accuracy, with low burr formation while entering and exiting the hole. The core stability of the drill is retained with optimum cooling via four internal spiral coolant holes making the drilling process safe and effective.

Sandvik Coromant offers a deep hole drilling strategy using its CoroDrill 861-GP and 861-GM drills in this brief video supplement to "A Happy Medium," a feature article in the October 2021 issue of Cutting Tool Engineering that delves into effectively drilling austempered ductile iron.
