Being a high depth of cut, form generating grinding process, Flute grinding operations are at high speeds and remove material at rates comparable to machining process rather than grinding. A combination of peripheral and surface grinding actions, the depth of cut, width of cut, form retention and surface finish are crucial parameters.
CUMI Flute grinding wheels are specially engineered high density (near zero porosity), resin bonded wheels which ensure that the form is generated with utmost precision and finesse. These wheels truly are a testament to the expertise that CUMI has built over the years.
