PCD Micro Reamers

PCD Micro reamers

With a head tipped PCD reamers from Preziss that can be manufactured up to 8 flutes where the demand of accuracy is required and at the same time the machining speed is a key factor. The tool body is designed of solid carbide allowing the maximum rigidity and reaching coolant supply individually for each flute with the variation for blind holes or through holes. The solid diamond head enables different complex geometries that can be shaped depending off the task to be done.

This kind of reamers are commonly used in applications such as valve guide machining in a cylinder head or bearing bore. In order to compensate euros due to run-out from machine spindle or tool holder, we recommend to be mounted over an A.R.C. compensation holder or floating chuck that can be easily compensated axial and radial to get a zero run-out.
The Preziss micro reamer tools are manufactured very accurately. Run-out measuring/adjustment can be done easily through the outside diameter of the body air check areas.
