Reply To: Honing vs reaming

[JohnFParticipant @johnf59703]

Hi Ken K, I have used both Delapena and Sunnen hones, mostly Delapena who are in Gloucestershire I think. Personally I have found little to choose between them and most of the tooling is interchangeable.

You can get permanent or disposable mandrels, small sizes are always disposable because there is no possibility to fit wear shoes.

If you PM me with your email I can send you a PDF of both companies brochures.

Stock removal is relatively slow compared to other methods of machining but it depends on size, material and length of the hole as to haw fast you can remove metal.

I feel sure the machines Gray is talking about are modern and more sophisticated than my old Sunnen honing machine which is about 60 years old I think but the principal is the same except there is nothing to preset or control the finished size other than experience.

Hope this helps John.
