Information/Parameters We Need To Quote For Honing

  • The material specification – this is essential to ensure accurate quoting as material properties differ, as do the speeds, feeds and products required to hone them efficiently.
  • Outside diameter – we need this to assess which machine the component can be held on.
  • Inside diameter – this is required to ensure we have tooling as honing tool sizes are available relative to the length of the bore diameter requiring honing.
  • Overall length – as with the first two, these are required for tooling and machine capacity judgements.
  • The type of bore required i.e., through, blind – if blind, is there a relief as honing tooling will never achieve full depth due to the design of the tools themselves. Alternatively, is it a tandem, keyway or serrated bore? All of these add complexity to the process, often requiring specialised tooling.
  • The bore tolerance – bore tolerance is a major factor when quoting the honing process as the tighter the tolerance, the harder it is to achieve, depending on the bore diameter.
  • The surface finish requirement – this is needed to ensure we are quoting the correct finish for the appropriate application. Unbelievably, you can supply a finish which is TOO good for certain applications.
  • Roundness, straightness or cylindricity specifications – these are required to ensure we can meet all required parameters.
  • Stock removal – this is essential to guarantee we are quoting you the best possible price as the more stock, the more time the process takes. If there is excessive stock, we also have to factor time for the material to “cool” as the bores can shrink back after they have heated during the honing process.
  • Whether any bespoke gauging is available from you as highly specialised gauging can be extremely costly and can sometimes render the job not financially viable if only a small volume is required.
