MOST die and mould machining is initially made in non-hardened steel with hardening only being done prior to finish machining. Sandvik Coromant has now introduced the possibility of machining in pre-hardened steel, thus eliminating many of the traditional production steps and reducing expensive tool changes and set-ups.
The new H10P grade from Sandvik Coromant ensures a very safe and easy to control cutting process. It provides long tool life, predictable and visible wear behaviour features. Produced from extremely fine-graded carbide with PVD coating, grade H10P can be produced with very sharp edges.
H10P grade is a semi-to-finishing grade for machining of dies and moulds in pre-hardened steel (harder than 54 HRC) enabling all machining steps to be done in one and the same set-up.
The technology to create this new grade quality is called Pluratech and is the result of extensive R&D efforts and market investigations around the world.
Pluratech quality can also eliminate the need for expensive EDM. The resulting benefits are shorter lead-times and better product quality.
The new H10P grade is available for CoroMill Plura ballnose cutters in diameters from 1-16 mm.
Adding CoroGrip to this -- the high precision power chuck individually balanced for HSM -- provides rigid toolholding with minimum run-out for even greater precision and tool life.
