Most aluminium is low in silicone content and has extremely low wear resistance. Turning aluminium with an uncoated insert such as a CCGT-AK, DCGT-AK or VCGT-AK is normally relatively easy. High silicone aluminium however is extremely abrasive and wear resistant and can cause fast tool wear in a normal uncoated carbide insert designed for aluminium. Korloy PCD turning inserts (poly-crystalline diamond) are first choice for high speed turning of high silicon aluminium, abrasive plastics, graphite, copper or wood.
A piece of PCD is brazed onto a solid carbide blank to create a PCD turning insert. The diamond DP150 grade is suitable for turning aluminium at speeds up to 3,000m/min with outstanding tool life. PCD is also ideal for machining any other abrasive non-metal material such as carbon fibre, glass filled plastics or abrasive plastic materials. The diamond PCD is always first choice for highly abrasive matierials.
PCD inserts from Korloy will fit into your existing turning tool holder or boring bar. For longer chipping aluminium we recommend a positive PCD turning inserts such as a CCMT or DCMT PCD insert Order online or call our technical team today for the best advice.
