Hi-Tek Manufacturing, Inc., leader in the production of aviation and power generation hot gas path turbine engine components, have just completed the purchase and installation of a new 6-Axis CNC CBN grinder. The grinding machine, Model 930E100, built by the Campbell Grinder Company of Spring Lake, Michigan, joins the growing list of grinders, both CBN profile and Creep Feed Continuous Dress, as Hi-Tek expands its overall grinding capability.
This latest acquisition boasts a thirty-six inch “X”, “Y”, and “Z” axis travel with rapid traverse speed of up to 300 inches per minute and a positional accuracy of 5-microns. In addition the machine is built with an automatic tool changer with a capacity up to 10 grinding wheels, as well as up to 12 inch milling and drilling tools. The “C” axis (rotary table) is 40” in diameter with a bearing capacity up to 2,000 lbs. and run out both radially and axially of 2.5 microns. The grinding spindle is 60 HP with a driven speed up to 7,200 rpm. Options include wheel dresser capable of utilizing roll or disk dressing tools, part probing, automatic tool and nozzle changer, CO2 fire suppression, and large, epoxy coated enclosure with interior lighting.
The new grinding machine has been installed in the newest area of the plant expansion completed in 2012. Hi-Tek recently installed a 22,000 gallon central oil filtration system that will provide temperature controlled grinding oil at 150 psi at the grinding wheel nozzles, filtered to 5-microns or less.
“This sophisticated grinding machine is just the latest in capital expenditures required to support recent sales growth,” said Barry Nehls, Hi-Tek Manufacturing, Inc. Sales and Marketing Manager. “Over the next three to five years we anticipate doubling our current grinding capacity in both CBN profile and creep feed grinding. This grinding machine is well suited for the large nozzles and blades required for the newer generation gas turbine engines,” he added.
Hi-Tek Manufacturing, Inc. has been serving the aviation and land based power generation OEM marketplace for over 36 years and is located in Mason, Ohio.
