How to Successfully Drill Deep Holes

Drilling deep holes, those with extreme diameter to length ratios, poses special issues for metalworking shops. These issues are exasperated as the hole’s diameter gets into the small and micro range.

Tools and Technologies for Deep Hole Drilling explains just that: some of the tools and techniques that are available to help shops accomplish successful execution of this sometimes tricky operation. Moreover, application of these tips can increase the quality of the workpiece feature and the number of holes that can be drilled per tool.

DMG MORI Hosts Cincinnati Grand Opening

DMG MORI Hosts Cincinnati Grand Opening

As a new assistant editor for Production Machining with only a month and a half under my belt, there’s no better way to learn about the industry than seeing it firsthand. I experienced this with a recent shop visit to Positrol Workholding, and continued the education with DMG MORI’s Cincinnati Grand Opening.

The event is being held at the company’s 14,500-square-foot Cincinnati Technology Center on August 15-17 and features a showroom for test cuts and demos by 18 individuals, including nine in service, three in applications, and six in sales. On display are exclusive technology cycles, a live high feed demo on a local production, the CMX 1100 V vertical machining center, and a demo on the DMU 50, a five-axis universal milling machine.

Successful Companies Make Accountability a Priority

Successful Companies Make Accountability a Priority

From Todd Palmer’s experience, there are five accountability pitfalls that business leaders should avoid if they want a high-performance organization.

The PM “About Your Business” contributor lists these as unclear responsibilities for managers and employers, resulting in misaligned goals, vague duties, and a lack of measurement processes to make sure things get done; executives that don’t follow up on goals, strategies and metrics; management misbehavior, such as missed deadlines, resulting in bad strategic decision-making and poor employee performance and execution; flawed corporate strategies that receive backlash, hurting management credibility; and territorialism and silos, with clients focusing on the needs of employees at the expense of the organization.

July Production Machining Business Index Holding Steady

July Production Machining Business Index Holding Steady

The Gardner Business Intelligence (GBI) Production Machining index registered 53.1 for July. This was down slightly from last month’s reading and below the year-to-date average. The index is still more than 20 percent above its July value from one year ago. The index readings for employment and backlog were stronger while readings for supplier deliveries, production, new orders and exports were lower. The GBI team closely monitors the backlog reading as it is considered a bellwether to capacity usage and ultimately machine tool sales. The July backlog reading of 53.2 is marginally above the year-to-date average reading. Compared with July a year ago, the backlog reading has increased by almost 40 percent. Backlog fluctuations often are a result of changes in new orders and exports.

Since the beginning of the year, the reading for new orders has decreased by 13 percent, ending July at 51.6, indicating that fewer respondents reported new order growth during July than June. In the trailing 12-month period, new orders have improved significantly with a July to July reading improvement of more than 20 percent. New order readings are in part driven by the dynamics of the export market, as exports constitute a portion of total new orders.

Additive Manufacturing is Not 3D Printing

According to our sister publication, Additive Manufacturing (AM), it’s time to recognize that AM is a stand-alone process that includes 3D printing. Pete Zelinski, editor-in-chief, in his August column, explains it this way, “3D printing is at the heart of AM just like turning might be the key operation in a subtractive machining process. As process facilitators, each core technology leads to a positive result—good parts.”

The interest in AM is more universal than any technology I can remember coming along in decades, and maybe of all time. This technology has captured the imagination of manufacturers and non-manufacturers. Our mass media seems to be enamored with AM’s potential, as is the discrete parts manufacturing industry.
