Hennig Inc. put together this video case study that shows how Advanced Machine and Engineering used the Hennig CDF (chip disc filtration) system to effectively remove chips when cutting tombstones and save floor space.
About 34 seconds into the video, Brad Patterson, director of operations and continuous improvement at Advanced Machine and Engineering, says AME purchased a Toyoda machine to improve on-time delivery of workholding products. Since the machine can run lights-out, it was important to make sure the total package—including the chip conveyor—was working as needed.
What’s special about this particular application is that floor space was a major constraint. Also, the machine is used to cut cast iron, steel and aluminum materials, producing anywhere from cast fines to long, stringy chips. According to Scott Cooley, business unit manager – chip conveyor and filtration systems at Hennig, AME needed a hinged belt conveyor system as opposed to the standard scraper design. By using the Hennig CDF, the company was able to save more than 2 feet of space from the standard design.
NineSigma, representing the General Electric Company, is accepting entries for its Inspection Technologies Challenge through February 24. This challenge is designed to find technologies, processes or approaches that can greatly increase the speed and accuracy of aviation parts inspection and greatly increase manufacturing efficiency.
Participants will compete for as many of three cash prizes of $15,000. Winning respondents who enter into a joint development agreement with GE will be awarded a $35,000 development grant to collaborate with GE to develop proposed solutions.
For this challenge, participants are asked to demonstrate their abilities by inspecting a Victorinox 4 inch paring knife instead of actual high-precision aircraft parts.
Visit this site for more information about the challenge and read the official rules. There is also a forum in which you can post questions about the challenge.
The digital edition of Modern Machine Shop's February 2015 issue is now avilable.
The digital February 2015 issue of Modern Machine Shop is now available. The cover story discusses the challenges that modern medical machine shops face and how they have helped shape one shop in particular. Other stories discuss how a castings supplier opened a fully equipped in-house machine shop, how a hydraulic system producer implemented an ERP solution and strategies in chip processing and coolant filtration.
Our Rapid Traverse section highlights EDM in three articles. The first is about a control that uses touchscreen navigation to help the basic user match the productivity and capability of an experienced operator. The second details how simultaneously rotating and tilting the workpiece enables the EDM wire to cut complex openings that may have different paths at the top and bottom of the opening. The third story discusses how the wire “spark erosion process” is used to dress a metal-bonded grinding wheel while still mounted in the grinder.
This month’s Better Production section includes case studies about how CAM software and new employees helped a job shop ramp up on a small budget, how a tool management system improved plant-wide communication, and how a vise-within-a-vise system enabled economic five-axis machining.
The Modern Equipment Review section highlights grinding equipment.
If you’re reading this blog post, you understand that Modern Machine Shop is more than just a print magazine. Our brand uses various media channels—social media, e-newsletters, print, a website and more—to help move the manufacturing industry forward.
One of the ways we do this is by organizing our content into various Zones on MMS Online. Zones are knowledge centers on key topics where information is aggregated and organized for you to find relevant information on that topic. Take, for example, our CAD/CAM Zone. If you poke around in it, you’ll discover a central hub for new products, videos, articles, columns, case studies and other editorial content we’ve collected on the subject. It’s also a great place to discover new suppliers of CAD, CAM and related software, if you’re in the market for it.
Mike Turner, operations manager at Derby Machine (Derby, Kansas) had a problem: Finding a vendor that could ID broach a blind hole in 304 stainless steel to proper size/accuracy specifications forced the company to ship its parts from Kansas to Chicago at $15 per part with a $100 setup fee, plus shipping both ways. Along with these costs, Mr. Turner says the parts were often damaged in the shipping process, so he began to ship them in ammo boxes for protection.
In search of a better solution, Mr. Turner decided to give an indexable-insert broaching tool from CNC Broach Tool (Marina Del Rey, California) a try. Though originally developed for lathes, Derby Machine would use the tool in a Haas mill. When the company received the tool and started setting up the machine, Mr. Turner says CNC Broach Tool’s John Gardner was very helpful in instructing the company on how to install the tool, as well as get the program, feeds and speeds correct.
According to Mr. Turner, the tool paid for itself several times over on the first run alone. From a single insert point, the company can broach more than 100 parts with a cycle time increase of only 2 minutes, 14 seconds. Today, the company has run more than 1,000 parts using very few inserts and has never lost the tool itself, he says.
“We never scrapped any parts because of the broach. It holds the depth and width through the whole run. I am extremely happy with the results and cost savings of this tool,” Mr. Turner says.
