Starting the New Year with New Thinking

Hi everyone, and Happy New Year! Back in October I posted some information here about Makino’s new Active Anti-Rust Unit for WEDM. We also showed this technology at our Expo in Auburn Hills in October with great reception from our guests. Most mold makers that saw this technology at the Expo were eager to get more information about it, saying that just a couple of jobs without rust issues would pay for the unit. On next Thursday, January 19th at 11:00 a.m. EST, I will be presenting a webinar at www.makino.com/events covering additional details of this new option. In the webinar I will be talking about how rust occurs, what has been available to date to combat rust in the work tank of a WEDM, and how Makino’s latest solution helps our customers save time and money. Register today and join me next Thursday to learn more!

Invest in Your Future with Full Tax Benefits

While we normally discuss topics that are specific to EDM technologies and processes, I found it important and beneficial to discuss the upcoming expiration of the 2011 tax benefits under the 2010 Tax Relief Act. I’ve seen and spoken with numerous manufacturers who have taken advantage of this policy, investing wisely in new technologies to grow their business and improve their competitive stance, while saving greatly on investment costs. Unfortunately, this policy is not permanent and full benefits only apply to manufacturers who have purchased AND installed equipment in 2011.

The previously passed 2010 Small Business Jobs Act allows companies to fully expense $500,000 in tangible property purchased in 2011 under section 179. In addition, businesses can also benefit from a 100 percent bonus depreciation deduction on qualified, new machinery and equipment.

These tax incentives provide businesses that invest in new machinery and equipment extensive savings and better cash flow in the year of acquisition. In some situations, tax savings on new investments have even exceeded monthly payments for the first year and more. Below is an example of this positive cash flow from tax savings.

If you would like more information on these current tax benefits, please check out our new webinar “Investing In Your Future,” hosted by Tom Scherpenberg.

For those still interested in taking advantage of this tax break, Makino has inventory available for many of our most popular machines, including the DUO43 wire EDM and EDAF2 sinker EDM – each ready for immediate delivery. Click here to learn more.

No More Rust on Your Steel WEDM Parts

The reason rust occurs on steel parts in deionized water is a simple chemical reaction. Positive iron ions from the steel workpiece dissolve in the water and react with oxygen molecules to form iron oxide, or rust, on the surface of the workpiece. This issue has plagued wire EDM shops since the beginning of commercial wire EDMs. Chemical rust inhibitors have been used as additives to the dielectric fluid, but these inhibitors require monitoring to maintain concentration and can shorten the life of the deionizing resin.

Makino has recently addressed this issue in water-based wire EDMs with a simple circuit added to the work tank that gives the workpiece a negative electrical potential. The circuit causes the workpiece to attract positive iron ions, preventing them from dissolving in the water and forming rust. Machines equipped with such a device have been shown to eliminate rusting of steel parts for up to 24 hours, even after machining has stopped. The pictures below illustrate steel parts that have been submerged in the deionized water of a DUO machine with and without the anti-rust unit. The part submerged in the machine without the anti-rust unit is fully covered with rust, whereas the other part is clean and rust-free.

This electric anti-rust unit was demonstrated at Makino’s Advanced Manufacturing and Technology Expo in Auburn Hills, Mich. It garnered a lot of interest from those looking at wire EDM technologies, and it should prove to be a tool that saves time and increases profit for Makino customers performing long run-time, submerged wire EDMing of steel workpieces. New machines can be ordered with the option, and the anti-rust unit can be retrofitted to currently installed machines.

For more information on this new technology, you can contact me at Jeff.Kiszonas@makino.com or by calling (248) 232-6208.

Both pieces were submerged in dielectric water for 24 hours. No machining was performed during this time.

Tech Tip

If you are having difficulty manufacturing or burning small/thin rib electrodes or tapping electrodes, give copper-impregnated graphite a try. You still need to use the standard graphite machining conditions, but the copper that is infused into the material makes it easier to machine the electrode to form and prevent chipping during the milling/turning process. The copper also gives added rigidity to the graphite, thus reducing flexure of the electrode during orbiting. This flexure can cause uneven surface finishes and inaccurate cavities or parts. Copper-impregnated graphite is available from several manufacturers, including Poco, Toyo Tanso, Ibiden and others. For information on copper-impregnated graphite materials and applications, contact Single Source Technologies (SST) at www.singlesourcetech.com.

The Expo is coming, October 12-13!

Makino in Auburn Hills, MI welcomes you to attend the Advanced Manufacturing and High-Precision Technology Expo. During this two day event on October 12 and 13, we will have seven EDM machines on display among a total of 17 machine tools. These EDMs will represent Makino’s diversity in the field, from the workhorse DUO-Series wire EDMs, to the ultra-precision UPJ2 horizontal WEDM. If its super fine finishes you require, especially in carbide and PCD materials, we will be demonstrating the new UPV-Series WEDMs that operate with oil instead of dielectric water.

Our newest sinker EDM, the EDAF-Series with ArcFree Technology, will be sporting the latest in on-board program generation, Makino Program Generator (MPG). The larger EDAF3 will be outfitted with our extremely precise Fine Hole option for drilling of holes as small as 11 micron, and L:D capabilities of over 100:1. At the pinnacle of accuracy for Makino sinker EDM technology are the EDAC1 and EDFH1. We will have an EDFH1 machine in our controlled environment room. This machine can be used as both a standard sinker and a precision EDM hole drill, just like our EDAF machines with Fine Hole option. The big difference is that the EDFH1 can achieve the finest of finishes and the smallest of details with ease.

It’s going to be one of the premier manufacturing technology events of 2011. If you’re in the Detroit area, stop in and see what Makino has to offer. Register now at www.makino.com/expo.

New Sinker Control Software

In our efforts toward continuous process improvement, Makino has released a new version of MGH5 sinker control software. This latest release provides enhancements to the Makino program generator (MPG) system. New burn strategies are now available, such as pin-gate and rib-machining functions. The MPG system replaces the old single-page screen, and it has been designed from the ground up by application engineers working closely with software development engineers. The MPG system enables anyone, from novice to experienced user, familiar with Makino or not, to quickly create an NC program using a conversational control interface. Once a program is created, it can also be viewed and edited using the model plan system quite familiar to long-time Makino users. All Makino sinkers ordered new will have the MGH5 control with MPG.

Q&A with Jeff Kiszonas: Swapping deionized with reverse osmosis

Q - Can Reverse Osmosis water be used in place of Deionized?

A – This would not be feasible. Reverse Osmosis (RO) removes particulates to a sub-micron level, but really does not control pH or conductivity levels.  The machine could be filled or “topped off” with RO water, but it would still need to go through the de-ionizing resin system for pH and conductivity control.  RO systems are also somewhat slow in filtering. The best practice is to fill or top off the water levels in the machine with whatever clean water supply is at hand, and use the resin system for operational control.
