In recent years Ceramics, Chrome and Carbide have provided a challenge for the Honing process due to the increased surface hardness properties of the newer grade materials. To address these harder materials Delapena invested in a state of the art sintering manufacturing process to develop a new range of super abrasive bonds with great success.
Proof positive of this success came when a customer asked us to help trouble shoot their process for honing of hard chrome cylinder liners. The customer was using a Delapena Powerhone to resize the Chrome plating in a cylinder using a conventional Silicon Carbide abrasive. The downside to using conventional abrasives is that the abrasives wear quickly and the Honing machine needs constant adjustment to maintain size. The customers Honing process averaged 60 minutes depending on the depth of the Chrome layer. A New Chrome bond developed by Delapena was then introduced and reduced this Honing process to 10 minutes.
Another advantage that the customer gained was that traditionally the worn Chrome plating was stripped overnight in Chemical tanks. Using a rougher Chrome bond abrasive allowed the Cylinder to be Honed prior to the plating process in a little under 20 minutes negating the need to chemically strip the cylinder.
|Process||Abrasive||Cycle time||Advantages / Disadvantages|
|Honing (Powerhone)||Standard Silicon Carbide||60 minutes||Higher production costs|
|Honing (Powerhone)||Chrome bond||10 minutes||Environmental – No Chemical stripping required|
