Hi-Tek Manufacturing’s Precision Grinding is Unmatched!

There are numerous types of grinding techniques used to produce specific shapes and finishes on a variety of both metallic and non-metallic components.  Specializing in the manufacture of hot gas path turbine engine parts, Hi-Tek Manufacturing has developed unparalleled grinding technologies in the areas of continuous dress creep feed and plated wheel CBN profile grinding.

The company’s grinding equipment includes a continuous dress creep feed that operates up to a staggering100 HP with a 20″ wheel, 4-axis continuous dress creep feed, 5-axis CBN, 1 & 2 spindle cylindrical verticals, and CNC surface grinders.

Creep feed grinding is similar to a milling operation where large stock removal is possible to exacting shapes and profiles.  Various types of abrasive wheels are used from aluminum oxide to ceramic composite.  By employing diamond dress rolls to continuously dress the wheel surface, precise shapes are achieved by the clean cutting abrasive wheel.

With CBN (cubic boron nitride) plated wheels, radial shapes and features can be easily produced on intricate turbine engine nozzles, blades, and other components.  Sometimes referred to as “superabrasive” grinding, Hi-Tek Manufacturing utilizes a number of these CNC 5-axis grinding machines on a variety of parts.

A key to the successful grinding by Hi-Tek Manufacturing is the use of central fluid filtration systems.  These filters provide water soluble coolant for creep feed grinders and grinding oil to the CBN or superabrasive grinding operations.  Each machine receives fluid to the grinding or cutting zone at the same concentration, temperature, pressure, and cleanliness to ensure uniformity in grinding operations across all machines.
