ELKA Precision was founded by Dr. Leonid Kashchenevsky, who has more than 35 years of experience (since 1973) in the development, design and manufacturing of ultra-high precision hydrostatic spindles, hydrostatic tables and hydrostatic slides.  Dr. Kashchenevsky's effective and innovative implementation of hydrostatic spindle technology makes ELKA Precision the first company in the world to develop ultra-high speed, ultra-high precision, hydrostatic grinding spindles with high frequency axial oscillations (up to 5 kHz) that can achieve rotational speeds of up to 120,000 revolutions per minute (RPM) .  These spindles are especially beneficial for precision internal grinding of small components made of difficult to grind materials like titanium, aluminum and stainless steel alloys.   In addition to reduced grinding time, they are also able to generate better surface quality up to mirror finish and higher geometrical accuracy.

Hydrostatic devices developed and manufactured under the leadership of Dr. Kashchenevsky are used in a number of high precision milling, turning and grinding machines all over the world, including the United States, Switzerland, Germany, United Kingdom, Japan, Canada, Australia and Taiwan.  ELKA Precision's extensive industrial and practical experience, combined with strong theoretical and scientific background produce highly efficient, robust and reliable hydrostatic spindles with a wide range of characteristics: from small ones with speeds up to 250,000 RPM, to large ones with low rotational speed and load capacity of up to 200 tons. 

ELKA Precision develops, designs and manufacturers a wide range of ultra-high precision customized hydrostatic spindles, which are tailored to optimally meet each customer's requirements.  Standard range includes ultra-high speed spindles with maximum speeds of up to 120,000 RPM, up to 140,000 RPM and up to 250,000 RPM, which can be effectively used for high precision internal grinding as well as micro-milling applications.

Work head grinding spindles developed by Dr. Kashchenevsky combine very high stiffness and load capacity with ultra-high rotational accuracy. In the speed range from 0 to 4,000 RPM radial error motion does not exceed 20 nanometers.

Unique combination of ultra-high precision work head grinding spindle and high precision ultra-high speed internal grinding spindle essentially improves the internal grinding performance for the manufacture of small size high precision components such as fuel injectors, hard disk drives, fiber-optic connectors, small bearing rings and numerous others.  The benefits are especially significant in mass production applications because both grinding accuracy and grinding productivity will be improved simultaneously.

Since 2007, Elka Precision has received two prestigious Small Business Innovation Research (SBIR) grants totaling almost $1,000,000 from the Defense Logistics Agency.  The first, a Phase I grant awarded in December 2007, provided resources to prove the feasibility of Elka Precision’s new hydrostatic spindle technology.  The second, a Phase II grant, was awarded in February 2009 to develop and manufacture a prototype of this new hydrostatic spindle and test it to prove its advantages compared to existing technology.  Strategic assistance in support of these grants came from the Connecticut SBIR Office, an initiative of Connecticut Innovations in Rocky Hill.
