Product & Process Overview © ECOROLL AG/ECOROLL Corp. 11-2006 Subject to revision ECOROLL Tooling Technology Based in Celle, Germany, ECOROLL AG Werkzeugtechnik is a mid-size company that designs, manufactures and sells tools and machines for improving the qualities of metal surfaces. These tools are used for roller burnishing, deep rolling and combined skive-burnishing applications (the latter developed especially for cylinder tubes). ECOROLL AG’s presence is world-wide, including a subsidiary in the U.S. (ECOROLL Corporation in Milford, Ohio) and representatives in Korea, Japan, South...

How does roller burnishing differ from deep rolling? Some use the term “roller burnishing” to refer to both processes. To clarify for our customers the unique advantages of both processes, ECOROLL prefers to dierentiate deep rolling from roller burnishing. Although the technological means are similar, the goals and results as well as the tools used for each process dier. When the application goal is to improve surface nish and/or increase bearing contact area, ECOROLL recommends roller burnishing. Deep rolling, on the other hand, oers a reliable process for increasing fatigue strength. That...

© ECOROLL AG/ECOROLL Corp. 11-2006 Subject to revision Mechanical Multiple Roller Tools ECOROLL’s multiple roller tools (Types G, R, RD, RAD, RA) are specially designed to machine cylindrical bores (both through and blind holes), stepped bores and internal and external cylinder surfaces. Multiple Roller Tools The RP, RDP, RK and RKA tools process similar non-cylindrical surfaces. Type G roller burnishing tool on a CNC-controlled lathe. These versatile tools feature convenient diameter adjustment and reliable, high-precision performance. Type G roller burnishing tool with internal coolant.

Machining a connecting rod with a Type G tool. The tools can be applied with CNC-controlled lathes, drills, milling machines and machining centers as well as with manually controlled machines. Mechanical Multiple Roller Tools © ECOROLL AG/ECOROLL Corp. 11-2006 Subject to revision Machining a three-section stepped bore with a Type RD tool. In addition, the tools require minimal lubrication and the wear parts are easy to change. Simple maintenance together with the short work cycle add up to considerable time-savings. Machining a universal joint shaft with a Type RA tool.
