ELKA Precision has been recognized for its advancement, innovation and development of hydrostatic grinding products by the United States Department of Defense and by Connecticut Business Support Organizations. In 2007 ELKA received a Phase I grant to develop its ultra-high-speed precision hydrostatic grinding spindle with axial oscillations of rotating shaft from the Defense Logistics Agency (DLA). This was followed by a prestigious Phase II grant in 2009 to develop and manufacture a prototype of this new hydrostatic spindle and prove its advantages compared to existing technology. The prototype development is expected to be completed by late 2010, and all testing thus far has indicated success.

During his successful career, Dr. Kashchenevsky has been at the forefront of hydrostatic product development. His work includes having:
- published more than 25 papers in professional journals (see list)
- been awarded more than 20 inventions (see list)

Spindles developed by Dr. Kashchenevsky include (see more):

• Ultra-high accuracy hydrostatic grinding spindles with maximum speed of up to 6,000 RPM and with rotational accuracy of 0.02 μm. More than 60 spindles of this type have been installed on high precision grinding machines in Germany.
• A custom hydrostatic spindle for jig grinding machines that allows for significant improvement of geometrical accuracy in the grinding of holes.
• A set of ultra-high precision hydrostatic spindles for internal grinding and micro milling applications. The spindles performed with three maximum speeds: up to 120,000 RPM; up to 140,000 RPM; and up to 250,000 RPM.

ELKA Precision was founded in 2007 by Dr. Leonid Kashchenevsky, a leader in the theory, design and manufacturing of hydrostatic spindles, hydrostatic tables and hydrostatic slides. Our line of hydrostatic products significantly improve grinding accuracy and reduce grinding times, improving overall efficiency and providing ultra-precise results.

ELKA Precision’s hydrostatic products are easily fitted to existing machinery, allowing the machinery to operate with higher precision and faster grinding cycles than brand new equipment - at a fraction of the cost. Every spindle developed by ELKA Precision is designed using detailed theoretical analysis and extensive practical experience in hydrostatic spindle assembly (including match lapping), testing and accuracy measurements.

Under Dr. Kashchenevsky’s leadership, ELKA Precision became the first company in the world to develop ultra-high-speed, precision hydrostatic grinding spindles with high-frequency axial oscillations of the rotating shaft. These spindles can achieve rotational speeds of up to 150,000 revolutions per minute (RPM) with radial error motion less than 40 nanometers.

ELKA Precision consistently designs and manufactures spindles, slides and spin-tables which provide better grinding quality, higher geometrical accuracy and less grinding times than our competitors.

ELKA Precision’s hydrostatic spindles have been proven accurate and reliable in grinding situations which require extreme precision. Hydrostatic grinding spindles developed by Dr. Kashchenevsky have been installed on optics grinding machines around the world, including United States, Germany and the United Kingdom. His hydrostatic devices are also utilized in high precision milling, turning and grinding machines across the globe, including the United States, Switzerland, Germany, the United Kingdom, Japan, Canada, Australia and Taiwan. With a detailed scientific understanding and over three decades of practical experience, Dr. Kashchenevsky’s products range from small grinding spindles with maximum speeds of 250,000 RPMs, to a hydrostatic spindle used to turn turbine shafts weighing up to 200 tons.

With more than 35 years of experience, Dr. Kashchenevsky offers a unique in-depth understanding of the theory, design, development and manufacturing of ultra-high precision hydrostatic spindles and grinding products. He earned a Masters Degree in theoretical physics and PhD in Mechanical Engineering from Moscow Experimental Research Institute of Machine Tools, and has developed analytical methods to calculate main characteristics for multi-recess journal bearings and a theoretical approach to predict rotational accuracy for hydrostatic spindles.
