The new ranges of insert tooling are suited to machining aluminium, sintered carbide, ceramics and plastics. The tools are also designed for tackling non-ferrous materials that are either very abrasive due to their high silicon content or have a tendency to exhibit chipping problems and form built-up edges.
Supermini tools with CVD-D or PCD cutting edges are available in diameters from 1.5 mm and with three different geometries to suit the application. H0 geometry with a rake angle of zero degrees is for machining hard, brittle materials such as carbides, pre-sintered ceramic materials, graphite and short-chipping brass.
H5 geometry with a rake angle of 5 degrees is used to machine abrasive and soft materials, including aluminium alloys with a high silicon content, fibre-reinforced plastics and other plastics with abrasive content. Diamond is also used successfully as a cutting material without chipping problems when working with precious metals and non-ferrous heavy metals such as platinum, iridium, gold, tantalum and titanium, as well as sintered metals like tungsten copper.
The specially developed, active HF chip breaker geometry solves virtually all machining problems caused by uncontrolled, stringy swarf. It is intended for use on long-chipping, non-ferrous metals such as all wrought aluminium alloys, and also copper and its alloys such as bronze and both lead-free and low-lead (long-chipping) brass.
