Single Source Technologies Introduces Topas Plus H.E.A.T. wire

Pine Brook, NJ--August 2008--Single Source Technologies, Consumables Group is proud to introduce a unique new Gamma phase wire, optimized to ensure the fastest possible part production while maintaining accuracy, Topas plus H.E.A.T..

This wire technology breakthrough is the result of two years of collaboration and testing by Makino and Berkenhoff at Berkenhoff's development facility in

Germany

. Berkenhoff is highly regarded for wire EDM products such as Cobra Cut, MegaCut and Bronco Cut.

Topas Plus H.E.A.T. is manufactured specifically to compliment Makino's H.E.A.T. Technology, but can also provide significantly faster machining speeds on all high performance wire EDMs. Initial results of tests utilizing Topas plus H.E.A.T. wire have seen increases in machining speeds by as much as 40 percent compared to traditional single coated wires.

Topas plus H.E.A.T. offers a unique approach to Gamma phase wires, utilizing a dual coating that provides more zinc content in the cutting zone, aiding the spark erosion process and providing superior straightness and cleanliness for automatic wire threading. When combining these properties with the Makino EDM features such as BellyWIZARD, H.E.A.T. (High Energy Applied Technology) and the newly developed SurfaceWIZARD, Topas plus H.E.A.T. delivers the most significant performance improvement provided by a coated wire to the EDM industry thus far.

Topas plus H.E.A.T. is available in 0.010 and 0.012-inch diameter wires on European and Asian style spools from Single Source Technologies, Consumables Group in North America . Learn more about Single Source Technologies at www.singlesourcetech.com.

New version of ED-CAM to be released at IMTS!

Your DisplayName here! — Fri, 20 Jun 2008 12:58:01 GMT

Our work has paid off, and the ED-CAM Version 5 is on the way! The new ED-CAM software for sinker EDMs is currently projected for release on September 8^,2008, to coincide with IMTS in Chicago .

We’ve included many new features to improve on our widely accepted ED-CAM version 4, including expanded model data, machining conditions technology, and electrode material types. Further options include carbide machining and Z-axis stabilizer. It can now provision a wide selection of cavity types, including rib, open side, connector, pin gate, speaker grill, EDM after pre-cut, and more.

We’ve also simplified the user interface, making it more logical when entering data. Users will also be happy to know we’ve added spreadsheet data import for those of you that lay out their processes on spreadsheets. The new version is also Windows Vista compatible, for those of you who have made that jump.

If you’re currently using ED-CAM version 2, Makino is offering a free software upgrade should you desire to do so.

As always, feel free to leave questions and comments for me. Despite the busyness of day to day life here at Makino, I will make time to respond!

Success Stories from PICO Wire Guides

Your DisplayName here! — Thu, 15 May 2008 18:05:56 GMT

Hey everybody, forgive me for the lack of posts recently. We’ve been busy helping customers with a few challenging applications.

Today I wanted to share a couple of success stories I received from customers using the PICO wire guide system.

The customer was using a U32j with PICO to thread two series of holes in a die plate. The die plate contained a total of 836 holes, half of them were 0.012", and half were 0.015" in diameter. The wire this customer used was 0.006" brass. To the pleasant surprise of this customer, the machine correctly threaded 835 of the 836 holes.

Many customers have had great success with the PICO guides in several different applications, including holes smaller than 0.020" diameter, and/or with pitch locations of less than 0.060" center-to-center. Another customer is actually automatically threading through a series of holes in a stack of parts with separation between each part in the stack. The part stack, including the spaces, is about 1-1/2 inches tall.

Many of these success stories have come from applications used in medical and aerospace parts manufacturing. If you’re using Makino’s new PICO system and want to share your experience, email me at jeff.kiszonas@makino.com. We’d love to hear from you!

Wire EDM testing in progress...results soon to come.

I've mentioned this before here, but I want to remind everyone that Makino is doing some interesting materials testing related to EDM and aerospace manufacturing. We've already had a lot of Wire EDM testing done - 18 samples, 3 different alloys (17-4PH, AL6-4V, 6061-T6), 1, 2, and 3 pass machining. Tests performed were recast thickness, Heat Affected Zone thickness, micro cracks, and Vickers Micro Hardness. We've seen some very impressive results that you can see in our webinar archives at Makino.com . We are now in the process of testing the same 3 alloys, same tests, but with Sinker EDM burns. We'll be adding Inconel 713 in the very near future. I'll have results from these tests in the next couple of weeks, and I'll presenting this data at the Montreal Machine Technology Show on Tuesday, May 13. Anyone interested in these types of tests should stop by if you're attending the show. I'll also be supporting our Canadian distributor, SST-Canada, in their booth, number 332. If you're at the show, stop by either the technical presentation on Tuesday morning, or the SST booth to say hi. If you'd like a copy of the test results of what we've done so far, just send me an email and I'll send you a copy.

Witness lines virtually eliminated with SurfaceWIZARD

Your DisplayName here! — Thu, 17 Apr 2008 13:57:19 GMT

Hey guys, I thought I'd let you all take a look at a new test cut piece that the EDM Applications Department in Auburn Hills came up with. This part shows how well SurfaceWizard technology handles interrupted and variable thickness cuts without leaving lines at transition points. With older technology, cutting across these kinds of details would leave anything from fine witness lines, to gouges that could be several thousandths of an inch deep. The only visible line here is on the left side of the "K" in Makino. Not only did SurfaceWizard allow cutting of this part without leaving severe witness lines, the technology also helps produce a straight, flat cut along the surface being worked. This part came directly off of the machine, with no hand work or secondary operations to "polish up" the EDMed surface. For more details on SurfaceWizard technology, contact me via phone or email, or call EDM Applications at our Die Mold Technology Center in Auburn Hills, MI at 248-232-6200.
