Company test results show that up to four spring passes can be taken with specific tools without any negative effects.Normally, we do not recommend doing that, and we have tools and geometry to eliminate that, Mac Arthur said. It normally reduces tool life and lengthens cycle time. However, when the tool is sticking out and contacting the entire wall at a 5-1 length-to-diameter ratio, the tool has more flex. So a spring pass is necessary to get rid of flexing and taper in the wall.A Lubricious LayerTo help prevent BUE and extend tool life, Matsumoto said OSG USA can deposit a diamondlike carbon coating on tools for aluminum ap-plications.We are trying to reduce the fric-tion so we can avoid chip weldingwww.guhring.com(800) 776-6170on the tools, he said.ctemag.com/cteguide.com35Aluminum.indd 35 6/15/20 6:07 PM'
