When savings are a requirement in parting-off and grooving operations due to the machining of costly materials, large-batch production or both, it is essential that the thinnest-possible insert width is used.

CoroCut QD dedicated parting-off and deep-grooving tools from Halesowen-based Sandvik Coromant (www.sandvik.coromant.com) are now available in smallerinsert widths, along with internal high-pressure coolant for improved production efficiency.

Staffan Lundström, parting-off and grooving product specialist at Sandvik Coromant, says: “As the only product currently on the market that offers over- and under-coolant in a tool this thin, the CoroCut QD inserts in 1, 1.2 and 1.5mm widths work well for deeper cuts and larger diameters across all workpiece materials.”

Considered a ‘hidden’ machining cost, component material waste is an often overlooked expense. Wider insert blades cut away more material than necessary during each parting-off operation, with the excess material ending up in the chip bin.

Using a thinner insert blade for parting off not only wastes less material but also allows for more parts per bar when using a bar feeder. Achieving material saving is especially important for manufacturers machining components from materials such as Inconel, titanium or cobalt chrome.
