"We were not sure about downtime for a new machine, but it has proven extremely reliable and we've used it to hone cylinders from 2.5 to 17 inches diameter, and six inches length to over 21 feet," Carter added. "We simply created a table with an adjustable-height V-block to support parts that overhang the machine. We have used up to a 21-foot drive-shaft length on the machine, and we can hone from both ends of the part if need be. Our cycle time for most barrels is about 30 minutes, which includes setup, honing and washing the part."
Whayne uses both roughing and finishing abrasives, removing scratches and rust, and imparting a specific crosshatch surface finish on the barrel bore. "We can increase the cylinder bore diameter up to 0.254 mm in relatively short time, removing rust and all but the worst scratches, and remain within Cat machine specifications," Carter said. "Our old hone simply could not do this. The HTA hone is easy to setup also. The control calculates the correct crosshatch angle. It's been a very reliable system, too, with no appreciable downtime.
"We scrapped a lot of hydraulic barrels or sent them out to other shops prior to acquiring this machine," Carter added. "Now we can salvage a cylinder with honing, and the cost and time for the customer is a fraction of replacement. In the current economy, customers appreciate this."
