New grades to meet exotic
material demands
Ceratizit unveiled a number of cutting tool innovations during the recent EMO manufacturing
technology exhibition to solve difficult-to-machine material issues.
Cases in point are the CTP5620 and CTP5630 grades, developed for bar peeling nickel-based
alloys – the types of heat resistant materials mostly associated with the aero engine and turbine
power generation industries. The search for ever higher performance means that these once
exotic materials are becoming more common, placing greater demands upon the metal supply
industry.
By combining innovative cutting materials with geometries specifically designed for the
heavy machining of high performance materials, Ceratizit has developed these two new grades.
CTP5620 is a fine grain grade characterised by high abrasion resistance in both the substrate
and the coating layers. CTP5630 is a heat resistant tough grade and is said to be proving
extremely reliable, even when used in less stable machining applications.
Initially, these new grades are available in the universally recognised YNUF 201220 insert
style, and can be used as a single insert for smaller diameters, and as a finishing insert for
tandem systems for larger bar diameters.

Fast frequency feedback
PCB retainers offer
high clamping force
Available from electronics packaging specialist Schroff, a new
series of PCB retainers provide a clamping force of more than
4000N, making them ideal for use in the most challenging
environments, especially those associated with aerospace and
defence systems.
