Sandvik Coromant Controlling crystals in inserts improves steel turning process
The company noted that the technology provides inserts with exceptional wear resistance and tool life.
Sandvik Coromant has announced the introduction of new insert grades for steel turning with Inveio uni-directional crystal orientation.
Sandvik said the crystal orientation in the inserts’ CVD alumina coating is normally random but that its technological breakthrough has been the development of a means to control the crystals’ alignment, which it directs towards the top surface. The particles then create a strong barrier towards the cutting zone and chip and provide very high levels of wear resistance as well as edges that retain their shape in use.
The range includes GC4325, which was introduced in October 2013 and is designed for steel turning. When it reaches its limit in metal removal rate due to high speed and long time in cut, GC4315 is used to withstand the high cutting temperatures, the company noted.
