Leading supplier of electro-chemical technologies introducing new machines for aero, auto, medical and nano markets
Farmington Hill, Michigan – EMAG L.L.C. here today announces the introduction of its ECM and PECM machines to the North American market. As a longtime European leader in these technologies, the company will sell and support these machines with application engineering, field commissioning and technical service from its Detroit-area location.
Electro-chemical machining takes many forms, but all involve the electrolytic dissolving of metal substrates. This technique is often utilized in applications involving hard-to-machine materials such as Inconel, high-nickel alloys, titanium etc.
Because ECM is a non-contact machining process with no heat input involved, the process is not subject to the variances inherent in conventional machining, such as tool wear, mechanical stress, microcracking caused by heat transfer, plus surface oxidation and recast layer present with EDM (electrical discharge machining), for example. By contrast, the ECM process is characterized by stress-free stock removal, smooth and precise transitions in machining contours with burr-free surfaces. End products from turbine blisks to dental implants and automotive industry products are ideal uses for this technology, according to Tobias Trautmann, product manager for ECM/PECM Products at EMAG ECM.
The many advantages of the EMAG ECM and PECM technologies for the end user include: low tool wear on the cathode, ideal for batch production; surface finishes to Ra 0.05, depending on the material, suitable for high precision pro
duction in nearly all machining areas; reproducible cutting depth to <20mm; extremely high-precision machining; no negative thermal or mechanical effects on the material, so no changes in microstructures; basic material properties are unaffected; hardness, magnetic and other performance properties are unchanged; nano and extremely thin-walled section contours are possible, critical in aero and medical applications, for example; high repeatability, owing to the consistency of the mechanical components and predictability of the machining conditions; minimal secondary operations; roughing, finishing and polishing in one machine. The process allows users to employ multiple fixtures and run the process simultaneously.
Standard features offered on the EMAG ECM Basic Series machines are a Siemens S7 controller with full graphics display, current relay and voltage monitor, pH control and conductance monitor, temperature control module, machining area of 1150mm x 950mm (45.27” x 37.40”) and two-handed operator safety controls. EMAG also provides ancillary equipment interfacing for work cell set-ups, including pre- and post-op cleaning stations and multiple machining units, as well as robotic workpiece handling.
Precise Electrochemical Machining (PECM) machines operate on the same basic principle of electrolytic dissolution, but include a mechanical oscillation mechanism for more intricate 2D and 3D microstructures. All standard machines include EMAG scalable generator technology up to 30,000 Amps, pulse frequencies to 100 kHz and a machine base of MINERALIT® or granite.
The Premium Series further offers precision imaging, surface finishes up to Ra 0.05 (relative to the material) and a high degree of precision in lowering speeds, essential for micromachining.
Complementing this new machine series is the EMAG test laboratory. Users can examine a variety of test cut scenarios to determine the optimum conditions for machining, fixturing, process performance and materials specification, matching the requirements to the most productive machines and systems available.

Leading supplier of machine tools partners with Oakland Community College; $200,000 agreement from Michigan New Jobs Training program to create 21 new jobs
Farmington Hills, Michigan – EMAG L.L.C. announces its receipt of a five-year, $200,000 agreement with Oakland Community College (OCC), through the Michigan New Jobs Training (MNJT) program, for the training of 21 new employees in manufacturing technology, CNC machine tools, mechanical maintenance, electrical and robotics disciplines.
Peter Loetzner, EMAG CEO, accepted the award from Dr. Timothy Meyer, chancellor of Oakland Community College, and J. Brooks Patterson, Oakland County Executive, during the Oakland County Economic Outlook Luncheon, held at the Troy Marriott on April 26, 2012.
Beginning the speeches at the event, OCC Chancellor, Dr. Timothy Meyer noted the critical importance of education and training in the creation and retention of manufacturing jobs in Southeastern Michigan, an area hard hit by the recent economic downturn in the auto industry and other manufacturing sectors of the economy. He then introduced Oakland County Executive J. Brooks Patterson, who continued this theme, citing the recent creation of 36,000 new jobs in Oakland County as well as other awards made to companies who’ve chosen to locate in the area.
Introducing Peter Loetzner, Meyer then detailed the collaboration between OCC and EMAG, noting how the study of mechatronics would raise the skill level of both engineers and the plant workforce to higher levels of technical competence and multi-functional abilities.
During his remarks, Loetzner recounted his own experience as a student in this now rapidly growing field of mechatronics, where mechanical engineering melds with electrical and electronic engineering to help students better understand the inter-relationship of components on a machine. Mechatronic engineers and field technicians are now highly valued individuals in many industries, Loetzner noted. He added that EMAG will have at least 20 openings in engineering throughout the next few years at his company, the result of increased sales and the EMAG commitment to serving the North American market from its expanding headquarters in the Detroit area. He further commented how such programs have the dual advantages of growing the manufacturing base in the area, as well as raising the skill level of the employees, which in turn attracts more businesses to Oakland County.
EMAG has engaged in training for its employees as well as its customers’ programming, operator and maintenance personnel throughout the company’s history, both in Germany and in America. The company sells its machines to job shops and original equipment manufacturers’ metalworking departments worldwide, with a heavy concentration in the automotive and off-highway machinery markets.
Loetzner thanked the OCC and Oakland County personnel who helped develop this program, especially Meyer, Patterson and Sharon Miller, the vice chancellor of external affairs at OCC. He concluded his remarks on a humorous note, “As we say in mechatronics, keep thinking INSIDE the box.”
Sharon Miller next spoke at the event, citing the creation of five new jobs programs in the last year, awarded to companies ranging from the start-up mode such as Oxus, a portable oxygen equipment distributor for the medical industry, to the multi-national truck parts supplier Meritor, who added 63 employees in Troy, Michigan as a result of the MNJT program.
Dr. Meyer concluded the speaking with several observations on the nature of education. He cited the need for institutions to be more proactive in redesigning their curriculum to better suit the needs of the local manufacturing base, plus the need to partner with more companies in the area, as well as community organizations. “After all,” he concluded, “community is our middle name!”
EMAG equipment covers the entire spectrum of machining processes in the metalworking industry, offering the latest technological advances in turning, drilling, milling, grinding, gear cutting, electrochemical machining and laser welding for the automotive, oil field, power generation and earth moving equipment industries. EMAG is a trendsetter in the field of vertical turning centers, multi-spindle machining centers and multi-functional production machines, and has become an important partner in the realization of complete process streams in the manufacture of automotive transmission, engine and chassis components.
Oakland Community College is the largest community college in Michigan, and the 21st largest in the nation. With five campuses throughout Oakland County, OCC offers degrees and certificates in more than 160 fields including university transfer degrees in business, science and the liberal arts, as well as workforce training and certificate programs. Approximately 750,000 students have enrolled at the college since it opened in 1965.
OCC also announced an award to Denso, one of the world’s largest suppliers of automotive components, totaling $2.6 million to support the creation of 169 jobs in e-learning, project management, leadership, quality and engineering at the company’s Southfield, Michigan facility.
