A major question for a tool engineer is” What are the limitations of reaming? The conditions under which CT Brazed reamers are used and the results vary considerably. Some type of reamers that will affect cutting action of the reamers are feeds or speeds, material, guided bushing and their use. But there are a host of principles that you need to keep in mind.
Materials and amount to ream
If a material is free cutting, a light constructed material would suffice. Conversely if CT Brazed reamers are hard, careful consideration is required for the choice of a solid reamer. No form of deflection is allowed and rake angles are necessary to comply with the work being done.
Work hardening is often expressed in certain forms of stainless steel that can be avoided by helical fluting or omitting a usual concentric margin. Is there a need for a concrete margin to be demanded, it has to be kept in width with a hair follicle. Floating holders are almost must on steel as they work hard. CT brazed reamers of Vega tools tend to last longer in stainless steel than high speed.
An usual practice is to ream from 0.004 to 0.012 diameter in finishing operations. Hardly it reams over 0.012.. If the size is smaller it is suggested that you ream between 0.006 to 0.0008 hardly in diameter.
