Advanced Grinding Solutions Ltd is the sole UK distributors for the Magnetfinish range of machines that have been designed to finish all types of cutting tools and to vastly improve tool lifetime and performance.

Magnetfinish has supplied many machines to specialist tool manufacturers and regrinding companies who are using this new technology to offer end users within the aerospace and mould and die industries premium solutions whereby the finest and most highly precise cutters are required for arduous machining tasks.

After being produced by a grinding process; cutting tools of all types can suffer from having jagged cutting edges and micro sized burrs. These impact heavily upon the lifetime of cutting tools and can affect their performance during heavy cutting. When milling, drilling or tapping at extreme speeds the resulting high temperatures that develop at the cutting edges are the main source for such problems because the tool becomes highly susceptible to wear. The patented Magnetfinish technology addresses this problem.

The Magnetfinish process polishes the flutes on all types of HSS and Carbide rotary tools such as endmills, form cutters and drills, provides the perfect conditioning or “edge honing” of the cutting edges (micron rounding of the edge) and is also used to polish profiles on taps and coated cutters. The Magnetfinish polishing process of the tools flutes results in a superior chip flow leading to the increased productivity of the tool. The tools primary cutting edges are machined to allow a defined and reproducible radius of between 3µm and 50µm to be created. This edge preparation process can increase the lifetime of tools such as ball nosed end mills by a factor of 4 and also allows more consistent machining results to be achieved as from using the tools for the very first time. The processing times for cutting tools are extremely fast with the average machining time for smaller tools being in the region of 5 to 10 seconds.

Advanced Grinding Solutions can arrange for sample cutters to be Magnetfinished and returned to customers for their inspection in order that improvements in tool lifetime and performance can be established and any tool manufacturers, regrinding shops or end users can contact Advanced Grinding Solutions Ltd on +44 (0) 2476 22 66 11 or via their website www.advancedgrindingsolutions.co.uk accordingly.
