The tooling’s innovative design overcomes issues caused by lack of height within many machining centres and has also removed the need for floating tool holders and adaptors - enabling the bore finishing tools to be held directly in the machining centre tool holders - while still providing the required high accuracy geometry demanded of bore finishing operations, e.g. roundness to within 1 micron, and surface finish up to 0.2Ra.
Using Engis’ flexible tooling system, the first tool passes through the bore with a single in-and-out stroke and its place is then taken by the following pre-set, single-pass tool.The number of tools used in any given application will vary depending on the amount of stock to be removed, the surface finish and geometry required and the material being machined.
Each of the new Engis pre-set single-pass bore finishing tools is coated in a single layer of diamond, which is permanently plated onto the tool, creating faster cutting/stock removal rates and meaning that tool sizes can be held for long periods without adjustment.
