New techniques are opening up to those in our industry thanks to a new approach to the single-pass finishing process as it relates to the manufacturing of gears. An article in Gear Solutions magazine discusses some of the changes that have been implemented, and the potential advantages of this recently discovered technology. Diamond tooling can be expensive - the cost of materials and the upkeep of your equipment can seem taxing. The key to the single-pass process, as reported by Gear Solutions, involves following the existing centerline of the bore to be finished with as little pressure as possible. This ‘path of least resistance’ may seem like an obvious avenue of approach for many gear manufacturers- but there are many in our industry who have lost time and money on something so simple. The article relates the information in this way:
“The key to the single-pass process is to allow the diamond tooling to follow the existing centerline of the bore to be finished with as little pressure as possible. This is normally done by allowing the tool, part, or both to float. Depending on many other variables, bore geometry to better than 0.2µm (.000008”) is possible. Sine all of the diamond tools are set to specifice sizes and do not require expansion during each cyle, the single-pass process is able to achieve unsurpassed size control in production (1 µm with near perfect repeatability). These results are very predictable and repeatable, thus lend perfectly to Statistical Process Control.”
It seems like a no-brainer that this process would be successful, but by constantly trying to augment tools, assembly fixtures and machine augmentations, gear manufacturers have been able to steadily increase their production rates while improving the precision with which they bore. According to the article- fuel pumps, power-steering pumps, hydraulic timing components, connecting rods, cylindrical bores, diesel rollers and most importantly, gears can all benefit from these newly developed approaches to the single bore process.
