Swedish tooling programs producer Sandvik Coromant has launched a brand new milling cutter with a steel 3D printed head. A primary for the corporate, the part marks a transfer towards the corporate’s involvement in 3D printing for end-use manufacturing.
An overarching pattern for the 3D printing trade,finish use manufacturing has turn into a key intention for a lot of stakeholders. Not solely does its profitable completion exhibit 3D printing’s transformation from a prototyping know-how to an actual competitor with conventional manufacturing, it additionally speaks to the scalability of the method.
On the finish of April this yr HP introduced the mixing of its personal 3D printed components into new system . As seen in initiatives just like the NextGenAM venture from EOS, Daimler and Premium AEROTEC, automation can also be a key a part of this. Just a few months earlier Carbon, the Silicon Valley-based firm behind Digital Mild Synthesis(DLS) 3D printing know-how, partnered with Ford to to ship 3D printed end-use automotive components with comparable and even superior properties to injection molded components.
As a part of the broader Sandvik engineering group, Sandvik Coromant’s new 3D printed instrument is only one a part of a variety of undertakings made to strengthen its place in additive manufacturing.

Investing in AM innovation
Based in 1862, the Sandvik AB group works inside mining and rock excavation, metal-cutting and supplies know-how. Its AM associated merchandise & companies embrace a consultancy for patrons experimenting with, or hoping to develop, additive manufactured components. In addition to a fast prototyping and serial manufacturing service, which it offers utilizing its in home powder mattress fusion (PBF) and binder jetting know-how. It additionally presents testing and high quality assurance, which incorporates entry to northern Europe’s largest R&D Middle for superior stainless steels, powder-based alloys and particular alloys, with subtle testing services and gear.
Investing closely in materials improvement, in 2018 the corporate allotted $25 million to determine a specialist additive steel powder manufacturing plant in Sweden, which is formally set to open in 2020. The funding will speed up the manufacturing of wonderful steel powders constituted of titanium and nickel, contributing to Sandvik’s current Osprey model of powders.

Extra lately Sandvik introduced an extra collaboration with Renishaw, a UK-based engineering agency and 3D printer supplier, to extend its capability for steel additive manufacturing. As a part of the partnership, Sandvik invested in a number of RenAM 500Q programs, supposed for set up in its specialist additive manufacturing plant.
Inside the industrial Sandvik AB group, Sandvik Coromant is the corporate’s tooling provider which was based in 1942 and at present operates in 130 nations and employs over eight,000 individuals.
The Light-weight CoroMill 390
The brand new Light-weight CoroMill 390 produced by Sandvik Cormorant, is a steel milling head primarily based on the CoroMill 390 design.
Thomas Wikgren, Supervisor Product Software Administration at Sandvik Coromant, explains, “When designing our new light-weight CoroMill 390, materials has been tactically eliminated to create the optimum cutter design for minimizing mass. That is referred to as topological optimization and it makes the cutter extra compact and considerably lighter than a traditional model, thus serving to machine retailers to spice up the productiveness of their long-overhang milling operations.”
The instrument, produced utilizing Sandvik’s trademark titanium alloy Osprey powder, has been particularly developed to beat vibration points throughout steel milling with lengthy overhangs. Such options are a standard requirement of parts used within the aerospace and oil & fuel sectors. Deep cavities in a CNC milled half may be compromised by vibration, resulting in slower manufacturing, shorter instrument life and poor floor end. When utilized in mixture with the corporate’s Silent Instruments milling adaptors the corporate reviews that the instrument can improve productiveness by 50%.
Wikgren provides, “a shorter distance between the damper within the adaptor and the leading edge improves efficiency and course of safety.”
The Light-weight CoroMill 390 can carry out long-reach face milling, deep shoulder and aspect milling, cavity milling, and slot milling. The instrument is accessible in 40 mm and 50 mm diameter variants.
