Parting and Grooving
Basically parting and grooving operations are defined by being 3-sided cut operations, right+left flank side and front side. Typically used to produce grooves and to cut-off (parting) pieces in a turning machine.

• Available –GCTX 3003 ( Width = 3 mm ) –GCTX 2002( Width = 2 mm )
• Application – Multi-MAT – Parting off and Grooving – 1st choice for Hard and short chipping materials
• Available –Only for GCTX 3003 ( Width = 3 mm )
• Application – Multi-MAT – 1st choice for soft and sticky materials – Parting off and Grooving – Turning with small d.o.c. up to 0.5mm PARTING & GROOVING fixing options (tool holder)
Tool holders have a fixed overhang and it doesn´t allow any adjustment on it. Best option for parting pieces diameter = 30mm.
PARTING & GROOVING fixing options (blade system)
Best option for parting pieces diameter <= 30mm. The shallow grooves are better performed when the overhang is minimized in order to avoid blade deflections and vibration risks. Economically is also better due to the 2 pockets/blade.

In summary, for successful parting and grooving machining, it is very important to select the chip breaker based on the type of chips ( long chips = PP and short chips = NN ) as well as the total length to be machined, in case of it is necessary less than 15mm, the blade-system allows to have a stronger set-up because it is possible to adjust the total cut length, positioning the blade shorter than the tool holder, offering less deflection risks and increasing the cutting parameters.
