Steel milling materials to expand the scope of application, for more users to improve tool life

Following the GC4330 and GC4340 steel milling materials of 2018, sandvik colman is working to extend these advanced blade materials to other milling cutters to expand their range of applications.

For example, CoroMill 300 circular cutter side milling and copying mills, CoroMill 245 multi-purpose face mills and CoroMill QD mills specifically for deep, narrow grooves and cuttings are available in the above materials.

GC4330 and GC4340 are made of Inveio?Coating and reinforced type post-treatment technology, users can greatly extend the life of the tool and improve processing safety.Now, extending these materials to other sandvik cormac milling cutters will bring their advantages to more workshops looking for ways to optimize steel milling.

Karl Emil Holmstr, global product application manager, sandvik colman?"The GC4330 and GC4340 materials were developed specifically to overcome some of the difficulties encountered in processing steel," said m.For example, the machining of hard, wear-resistant steel can cause a lot of wear and tear on the back surface of the blade, especially in the case of high-speed, continuous cutting for a long time.In addition, due to the instability of the fixture or the use of long overhang and processing under unstable conditions, will increase the risk of blade collapse.Another risk is that thermal fluctuations during processing, particularly in wet cutting conditions, can lead to cracks and sudden breaks in the blades."

Among the many design properties of GC4330 and GC4340, the most notable is the Inveio coating, which is optimized.Inveio?It is a technological breakthrough in the orientation of single crystal of alumina coating, which gives the blade higher wear resistance and longer service life.In addition, the particle size control of the matrix material of these two materials is just right, making the performance of the blade more reliable and more predictable.

GC4330 belongs to medium hardness material, suitable for rough machining to semi-finished machining surface milling;The stronger GC4340 is the preferred material for roughing the square shoulder and slot milling.Both of these materials have now been extended to the above CoroMill 245 and CoroMill 300 milling cutters, as well as the CoroMill 360 heavy duty face milling cutters, CoroMill 419 high feed milling cutters, and lpmh-pm insert cutters.

In addition, the CoroMill 365 high safety face milling cutter now provides GC4330 material, while the CoroMill 216 ball end milling cutter and CoroMill 415 small diameter high feed face milling cutter and the CoroMill QD milling cutter provide GC4340 material.

This greatly extends the existing range of two materials: CoroMill 390 and CoroMill 490 square shoulder milling cutters, CoroMill 345 face milling cutters, CoroMill 210 high feed milling cutters, CoroMill 200 copying milling cutters, and CoroMill 331 milling cutters for slotting and cutting.
