Electrical Discharge Machining (EDM)

We are the leading experts on sinking EDM technology in the world. Dr. Sc. Mark Otto, the founder of the company, is the most sought-after EDM technology expert. He's internationally known for his in-depth knowledge of the EDM process. Dr. Otto holds over 80 patents all over the world, most of them related to the EDM technologies and processes. His inventions in the area of EDM have become world-famous and highly successful. His first widely known invention was the EDM process control system, EDM-3AM. Over 2500 devices were sold all over the world, including USA, Germany, Italy, and France. The invention was awarded multiple gold medals at European High-Tech exhibitions.

When it comes to sinking EDM, we are the answer. And, our new EDM machine, OTTO Pro OP4030, is the only machine you may ever need, if you would like to have the highest return on each dollar you spend. However, you don't have to take our word. We will happily demonstrate the machine in action to any and all interested clients. Just let us know, and we will get in touch with you as soon as possible.


Mark Otto was born in July of 1940. He graduated from Kiev Institute of Technology with the Electromechanical Engineering and Industrial Automation major in 1961. He earned his first doctorate degree (Ph.D.) in 1968 from ENIMS (Experimental Scientific Research Institute of Metal-cutting Machines) – or, to put it in more simple language, “The Machine Tool Research University”. His thesis was titled uilding Generators Using Semiconductors and Optimization of Technology to Reduce Electrode Wear.” He earned his second doctorate degree (Ph.D. Dr. Sc.) in 1988 from The Institute of Electrodynamics- Academy of Science. His thesis for his second doctorate was: sign and Production Implementation of a Range Of Generators with Built-in Process Control Systems, and Development of EDM Technology for These Generators.”

In June, 1964 Dr. Otto started working in the area of EDM at ENIMS in the department of New EDM Methods. From 1970 to 1990 he had advanced to the position of Lead Scientist of “Power Sources and Process Control Systems for Generators” Laboratory at ENIMS. Dr. Otto emigrated from Russia in 1990. From 1991 through 1994 Dr. Otto worked as an EDM Technology consultant for leading EDM Tool manufacturers in Italy and Germany. From 1994 to the present, Dr. Otto has been engaged in the design, development, implementation, and sales of his EDM inventions and EDM Technology consulting through his companies in the USA and Europe.

Dr. Otto has made numerous ground breaking contributions to the science of EDM during his tenure in Russia and in later years:

While in the USSR:

  • Design and development of the first wide-range semiconductor pulse generators for EDM machines including organization and implementation of a long-lasting production of these generators.
  • Design and development of the Adaptive Programmed Process Control System for EDM and implementation of its production.
  • Design, development, and production implementation of the EDM Finishing and Polishing Module for relatively large surfaces.
  • The afore-mentioned inventions were licensed to major EDM manufacturers in Switzerland, Italy, and Hungary.

In the West:

  • Design, development, production implementation, and sales of the World-First Complete Electrode Arcing Protection System, which also drastically improved metal removal rate and significantly reduced the electrode-tool wear. Over 2,800 such devices were sold since 1994 bearing the name of Anti-Arc Automatic (also known as: EDM-3A, EDM-3AM). The invention/device received many awards and Gold Medals at different high-technology exhibitions in Belgium, Germany, USA, and Slovenia.
  • Designed and developed the world-leading high-technology generator, process control system, and EDM technology of the highest level known in the industry for the largest and renowned manufacturer in Germany.
  • Designed and developed a new, economical, high-technology generator with a highly advanced process control system combined with the PC-based CNC software whose level of performance matches, and in some cases exceeds, that of the most expensive EDM machines of today. A new machine incorporating this exclusive technology, the OTTO Pro launched by Belmont Equipment & Technologies at IMTS 2010, provides performance comparable to the highest end machines at a very affordable price.

Dr. Mark Otto presently plays a key role in two companies. Both companies are deeply involved in the design, development, implementation, and sales of special performance-improving electronic devices for EDM machines, and EDM machines themselves under the brand of OTTO Pro.

Otto Tehnologija d.o.o. This company is owned by Dr. Mark Otto and is located in Slovenia.

Otto Electronics, LLC Dr. Mark Otto is a General Partner and founder of this company which is located in the United States.

Belmont Equipment and Technologies is partner in development of the Otto Pro machines and their exclusive distributor in the US and Canada.
