Ruemlang, Switzerland - September 2, 2014 - KAISER Precision Tooling, a leader in premium high-precision tooling systems and solutions for the automotive, mil/aero, energy, medical and watch-making industries, today announced its EWH precision boring head. The EWH has been developed specifically for effective use with exotic materials such as titanium, making it ideal for the aviation industry.

Built for use with coolant pressures of up to 70 bar, the EWH is designed to the highest standards, with an ultra-rigid monoblock construction. This means it can meet the requirements of rigid tools and high coolant pressure that are needed for the efficient machining of difficult work piece materials.

The new boring head is available with a length of 95mm or 155mm and includes HSK/SK/PSC interfaces. The EWH hydraulic clamping delivers a form- and force-locked connection that clamps the tool holder perfectly, with high pressure around the entire circumference. This is a superior solution to clamp over side lock screws, which have a point and line contact on the circumference.

High coolant pressure of over 50 bar is important to ensure effective cooling, especially when cutting HRSA and titanium work pieces with low heat conductivity. If coolant was supplied with insufficient pressure, it would vaporize, and temperatures would therefore rise - reducing the hardness of the cutting material, and decreasing the lifetime of the cutting edge. The high coolant pressure supports chip breaking and helps achieve enhanced chip forming.
