By combining Glebar's movable work rest assembly with its intuitive CNC work wheel dresser
with custom radius compensation programming, Glebar was able to significantly reduce scrap rates, as well as eliminate an extra step from the previous manufacturing method which had left unacceptable tool marks on the tip surfaces.
A CNC-driven table-mounted wheel dresser
accommodates wheel shape changes without any templates for faster part setup and changeover.
The wheel dresser
shown has tough, hardened teeth that clean and shape the wheel quickly.
A wheel dresser
can also be used to flatten the grinding face or "true up" a lopsided grinding wheel.
In addition, a wide range of structural and mechanical improvements have been incorporated, including a stiff, thermally stable cast iron bed, a programmable CNC wheel dresser
that eliminates templates for improved reliability and reduced setup time, a state-of-the-art negative pressure mist and coolant containment enclosure, and a single fluid system for both the hydrostatic and fluid power requirements.
Hydraulic dressers incorporated the wheel dresser
into the automatic cycle of the machine, but still heavily depend on precision cams.
Clamped on a Maegerle with a continuous wheel dresser
for the surface forms, consecutive CF passes on each of the six surfaces yielded a completed part without any refixturing.
In fact, on some full blown machines, add-ons such as a continuous wheel dresser
with wheel wear compensation can carry a price tag in the $150,00 range.
