Type IV rockers are forged and the outer surface is quite hard but the core is more ductile. A carbide drill is required to drill holes. I made fixturing to support the rockers with the web flat for drilling in a drill press.
Thinning out the web is done with carbide burrs. EDM might save some time. The last step that should be done is to shot peen them after all material removal to increase their strength. |
