its glaze busting / Honing and as nial has done you can do it yourself just dont go mad 
You need to hone a cylinder to create a "rough" surface so the new ring will wear in and seat in the cylinder. Without honing the new ring will not seat and you will have power loss, greater oil consumtion, low compression and a poor running engine.
