Super-fast circular groove milling - milling insert

Babcock International Group (Babcock), the defence company, has been awarded a two-year contract extension by the UK Ministry of Defence (MOD) to continue to provide technical support services across the UK armed forces.

The Boeing X-37B spaceplane is to begin executing a series of novel manoeuvres, called aerobraking, to change its orbit around Earth, the US Space Force has announced.

Sandvik Coromant releases products in two stages throughout the year. Andrew Allcock reviews some of the highlights from the Coropak 2 unveiling last year. Composites machining, medical, wind power plus specific product developments are covered. (This is an extended version of a feature first published in Machinery magazine, February 2010).

Dimensional accuracy, stability and process reliability are assured, as the torque generated during machining is dissipated into the body. Horn offers two body types, the first having a cutting edge diameter of 100mm. It is equipped with 14 type 406 indexable inserts, which produce seven effective cuts ranging from 9.6mm to a maximum of 12.9mm wide. Milling depth is up to 20mm. The second body type is equipped with 12 cutting inserts of type 409 and has a cutting edge diameter of 125mm. On this tool, the cutting width with six effective cuts can be adjusted between 12.9mm and 18.8mm. Maximum milling depth is 32.5mm. The successful 406 and 409 type indexable inserts have been chosen for the application. They are precision ground and achieve outstanding surface quality at the base of the groove and on the flanks. Double positive axial and radial rake angles ensure a soft cut. The tangentially screwed cutting insert's trailing chamfer produces a secondary cutting edge, resulting in outstanding machined surfaces. An additional free-form surface chamfer provides a stable wedge angle and very smooth milling. www.phorn.co.uk

In celebration of World Space Week, Space-Comm Expo has announced visitor registration is now officially live and open for the London ExCeL, event, running 11-12 March 2025.

A new side milling cutter for stepless adjustment of groove width has been introduced by Paul Horn, and is available through the firm's UK subsidiary, Horn Cutting Tools, Ringwood. The milling body features a central sleeve that enables the required groove width to be adjusted easily on a pre-setter.

Tooling manufacturer, Horn has introduced a new carbide insert grade, SG66, for turning components from steel that has been case hardened to 58 HRC.

The NeoMill-Alu-QBig indexable insert milling cutter from Mapal stands for top performance in high-volume milling of aluminium. The tool manufacturer thus offers a very economical solution for use on high-performance machines, such as those found primarily in the aerospace industry.

Walter has now launched its new X·treme Evo Plus drill from the DC180 Supreme product family that is now available up to 8XD for the first time.
