Rather than using taps to thread steel prior to hardening, a growing number of shops are opting to thread mill heat-treated steel.

Why are all your parts turning into toast? Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, offers insight into rotary diamond dressing.

Do you have the right grit for a smooth finish? Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, takes a look at a common problem shops have with getting the surface finish that they want in the 3rd episode of the video series.

Part of CTE's October cover story, this video sidebar follows tool grinder Jim Clark as he employs the ANCA CNC toolgrinding machine at Hamill Manufacturing to create custom geometry onan endmill for a military application.

As part of its occasional product focus video series, Cutting Tool Engineering Plus presents a closer look at the GrindSmart Nano6 from Rollomatic SA.

Produced as an online complement to the October 2009 Productive Times article in Cutting Tool Engineering, this brief video looks at Myles Tool's decision to use a wheel truing machine from Rush Machinery.

Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, fields a question from a shop that hasn't had any luck with ceramic abrasive. Watch the 2nd episode of the video series now.

Watch Sandvik Coromant Co.'s CoroMill 365 cutter mill an engine blockmade of compacted graphite iron in this online complement to our September CTE cover story.

The debut episode of Cutting Tool Engineering magazine's Grinding Doc Video Series fields a question from a shop wondering about the relationship between coolant velocity versus the flowrate. Dr. Jeffrey Badger, the host of the video series, takes a look at the coolant issue.

Check out this brief video from Kennamental Inc. showing a side-by-side comparison of an HSS tap vs. a solid-carbide tap. The video accompanies CTE's August cover story on selecting the right tap for different workpiece materials. The split-screen video demonstrates the significant productivity advantage of the first solid carbide tap specifically engineered for tapping steels.

CTE's July cover story examines drills with interchangeable carbidetips, while the accompanying video shows how interchangeable-tip drills permit quick inspection and replacement.

U.S. moldmaking has been hit hard by overseas competition. Makers of molds for glass products face added pressure because alternate materials—mostly plastics—are replacing many glass applications. Quality Mould Inc., one of a handful of independent glass mold shops remaining in the U.S., machines molds for pressed-glass products. The shop combines traditional craftsmanship with CNC machining and CAM technology that set its products apart from those of overseas competitors. Quality Mould is also leveraging its longtime skills to diversify its customer base.

Not all landing gear tests require facilities the size of small towns or the ability to land the 787 Dreamliner, which is discussed in the March 2009 cover story of Cutting Tool Engineering magazine. As impressive as Boeing's landing gear tests are (visit the Boeing Web site to view a brief overview of Boeing's landing gear technology), CTE Plus takes a look at the other end of the spectrum.

Presented here is avideo of a SideLok long-edge milling cutter from Valenite LLC, Madison Heights, Mich.,machining Ti6Al4V at a cutting speed of 150 sfm, a feed rate of 4.5 ipm, a WOCof 0.375" and a DOC of 1.5" on a 30-hp HaasV65 CNC mill. The key technology of the SideLok systemis the co-location of the fastening system in the normally unused chip gullet space.

Stef Wertheimer is the founder of Iscar Metalworking, which began operations in 1952 as a one-man tool shop in northern Israel. Today, Iscar is a multinational business, 80 percent of which was purchased in 2006 by Warren Buffett's Berkshire Hathaway Co. In a wide-ranging interview with Cutting Tool Engineering Editorial Director Alan Rooks, Wertheimer recounts the history of Iscar and his project of developing industrial parks throughout the Near East.

Editor's Note: This video report is presented as a supplement to Cutting Tool Engineering's January cover story, "Down-hole, High-tech." The animation from Phillips Engineering Technologies was created to clearly illustrate the operation of a twin-ram vertical turning lathe.

The practice of turning threads on a lathe is well known but oftennot well-understood. Toolmakers offer their recommendations on how todo it the right way. By Bill Kennedy There are nearly as many ways to produce threads as there are types of parts that require them. Threads can be cut with a die, rolled, ground, tapped or milled, using lathes, machining centers or specialized machines. In the video, Frank Battaglia, staff engineer for Kennametal Inc., Latrobe, Pa., provides a couple of pointers regarding the use of shims with laydown threading inserts to achieve optimal results.

Data Flute CNC's Cliff Flynn, director of research and new product development, gets rough with the company's AFDH finishing tool in this 5-minute report. Flynn noted that the demonstration provided at IMTS 2008 was purposely aggressive on the finishing tool to underscore its finishing ability.

Cutting Tool Engineering Editor Alan Richter sat down with Carlos Cardoso, the chairman, president and CEO of Kennametal Inc., at the recent IMTS 2008 show in Chicago. The 7-minute report addresses Kennametal's goals for diversification and expansion globally, and how that has impacted the company's worldwide sales. Cardoso also notes tht Kennametal will continue co-development tools with others because that's what's best for customers.

Cutting Tool Engineering Contributing Editor Bill Kennedy offers a video supplement to the October cover story, which looked at how small shops are taking advantage of big opportunities by making military parts.
