Advancements in component material technology means that cutting tool suppliers have an ever increasing responsibility of being able to supply tools that can efficiently cut new materials. This responsibility is even more apparent when supplying tools for turning stainless steels.
Stainless Steel Challenge
The new 7000 series, MC7015, MC7025 and MP7035 have been designed to be an easy-to- choose selection of grades and chip breakers. Such is the variance in the properties and machinability of stainless steels, different tool grades matched with a suitable chipbreaker is essential to achieve reliable high volume, unmanned production. A "one grade and breaker suits all" solution is no longer the best way to realise the high rates of efficiency needed for todays demanding production environment.
MC7015 is a multi layer CVD coated grade with a smooth cutting edge to prevent chip welding during higher speed, lighter cutting applications. MC7025 also has a mutli layer CVD coating, together with an optimised substrate that displays excellent plastic deformation properties. This combination of coating and substrate makes it ideal for a wide range of medium cutting applications. MP7035 is manufactured with a PVD coating for prevention of chip welding and a substrate specialised in thermal shock and fracture resistance. These properties make it the first choice for interrupted cutting and rough machining.
