Gühring has expanded its grooving and parting-off to include a new grade with a blade width of 3 mm for parting-off stainless steel materials. The System 222 expansion adds to the company’s existing indexable inserts for steel materials. With two cutting edges and a length of 22 mm, the new indexable insert is suited to parting off all common bar diameters.
The enhanced series also offers an extensive range of clamping holders with and without an internal coolant facility.

Many production facilities are seeing an increase in demand for stainless steel in particular, notably in sectors that include medical, automotive and general mechanical engineering. With this rise in demand – and following the successful launch of its 3 mm indexable insert for steel machining – Gühring has therefore developed the new indexable insert for stainless steel materials. In series production, this insert is suitable for parting-off operations on turning centres with a bar-feed system. As parting-off is frequently the last application in a machining cycle, process reliability is critical. If the tool breaks, the finished component could be subject to damage at its point of highest value (after significant machining time). For this reason, it is important to use an insert with application-optimised geometry, material composition and coating.

In one customer machining example, a feed-rate increase from 0.06 to 0.08 mm resulted in a reduction in machining time using the same cutting speed. With a series run of 15,000 components, the customer made a time saving of more than five hours. Despite the higher feed rate, the Gühring solution created 40% more parts per insert edge with a 25% productivity gain.
