Reaming can be most cost-effective way to produce accurate holes
Technological advances in cutting tools, machine tools and toolholders have allowed machinists and manufacturing engineers to increase holemaking efficiency by eliminating the number of tools required to produce accurate holes. High-performance drills are the best example of these technological advances. In the past, it was common for a machinist to spot-drill, drill and then ream to achieve accurate hole geometry.
Component cleanliness requires effort throughout manufacturing process
Specifications for particulate and film-residue cleanliness are a matter of course for many machined components. In addition to the parts cleaning procedure, manufacturers must consider the entire process chain when seeking to efficiently achieve and maintain the required level of cleanliness.
Overcoming five common challenges when turning
While it's nearly impossible to quantify the most common challenges or most important considerations when turning, experts agree that the five aspects of turning discussed below should be considered. It's important to note that each factor has the potential to impact the others.
Horizontal machining centers’ enhanced capabilities shorten payback periods
At roughly twice the price of a vertical machining center, do horizontal machining centers make sound financial sense? Absolutely, according to Scott Baldus, product specialist at Okuma America Corp. The Charlotte, N.C., machine builder offers both VMCs and HMCs, yet, Baldus noted, HMCs provide, on average, more than three times the spindle utilization of VMCs.
Aluminum can be hard to drill, despite its easy rep
When drilling, perhaps no variable is as important as the workpiece material. It dictates drill geometry and substrate, tool coating, coolant application, and speeds and feeds. While known for its relative softness and ductility, misconceptions abound among those who regularly drill aluminum.
A machine for dry grinding gears
Italy-based Samputensili S.p.A. unveiled a machine that eliminates the need for cutting oils when manufacturing gears, thereby reducing grinding costs. During grinding, oil-based lubricants cool the workpiece, as well as reduce friction and help evacuate chips. On the downside, however, oil use accounts for a significant amount of a grinding operation's total cost.
Form of solid carbide harder than diamond
Researchers at North Carolina State University reported the discovery of a distinct form of solid carbon they estimate is about 10 percent harder than diamond and could play an important role in machining. They also claim to have developed a relatively inexpensive technique for producing the substance, called Q-carbon, at room temperature and ambient atmospheric pressure.
Ring in New Year with new site
We at Cutting Tool Engineering celebrated the New Year by unveiling a major overhaul to the design and functionality of our website, ctemag.com. Sporting a bright new design with larger text and images, ctemag.com is not only easier on the eyes, it's also easier on the fingers thanks to new navigation and search functionality.
Gripping threaded parts: Medical Manufacturing
Cutting external threads is one of the more difficult machining operations. Achieving the proper thread form can be challenging, and tool chipping and premature tool wear are often problematic because of insufficient surface speeds and high cutting pressures.
Avoiding machine crashes
Everyone crashes, I was once told. It's likely true. However, not all crashes are created equal. There are fender benders that just break small tools, and then there are head-on collisions that ruin much more—including your day. CNC machine crashes are relatively easy to avoid. They often occur during setup and debugging.
One machine, two processes
Additive and subtractive manufacturing may be conceptual opposites, but a new partnership aims to show that the two can make a good team. Two of the partners are New York organizations: the Rochester Institute of Technology (RIT) and Elmira-based Hardinge Inc. RIT researchers are incorporating additive-manufacturing capabilities into Hardinge's Bridgeport GX 250 5-axis vertical machining center.
Dressing with PCD: General Industry Coverage
Ask the Grinding Doc: When I ran out of single-point dressing diamonds and got desperate, I mounted a PCD insert to dress an Al2O3 wheel. Is there any danger in doing that?
