Engis offers honing tool for machining centre use

Superabrasives specialist Engis UK has launched a tooling solution which effectively replaces the expensive and highly skilled 'black art' of honing and puts the process firmly into the range of standard, repeatable and cost-effective machining centre tasks, on standard vertical and horizontal CNC equipment.

The new tooling's design overcomes the issues caused by lack of height within many machining centres and has also removed the need for floating toolholders and adaptors, thus enabling the bore finishing tools to be held directly in the machining centre toolholders 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 0.2 Ra. Using the new 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 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.
