30% longer tool life
With this parting off plate you achieve maximum performance in high-grade steel
Gühring is expanding its successful grooving programme “System 222 ” with a parting off plate with a grooving width of 2 mm. Thanks to its special chip former for ISO-M materials, this indexable insert ensures high process reliability, outstanding tool lives and improved surface qualities when parting off high-grade steels.
Solution for outstanding surfaces when parting off
High process reliability is crucial when parting off, as parting off is often one of the last process steps in the production of turning parts. The requirements are often very high, especially for smaller turning parts that are manufactured from bar stock up to Ø 32 mm on sliding headstock lathes or multi-spindle machines. However, this is where difficulties often arise: “We always encounter the same challenges when parting off: Long winding chips, chattering component surfaces and broken tools,” explains Marc Wiesner, Product Manager for grooving and turning tools at Gühring. To ensure that the surface finishes on the plane faces still meet the high requirements in the end, reworking with a separate turning tool is often the only solution.
Marc Wiesner is certain: “Only with a tool that reliably breaks and constricts chips can we fulfil our customers’ requirements for component quality.” It is precisely these properties that characterise the parting off plate from Gühring’s System 222. The cutting insert has a specially developed chip former for materials in ISO group M. This ensures reliable chip breaking and constant chip constriction in the most important high-grade steels. At the same time, the high-precision insert seat with maximum accuracy ensures excellent process reliability.
With this special chip former and a customised cutting edge geometry, the grooving insert enables excellent surface finishes – constant values of Rz < 4 µm were achieved in internal benchmarks. For you as a user, this means that you no longer have to rework with separate turning tools, saving you time and tooling costs.
High system stability enables material savings
But these are not the only savings that are possible with the parting off plate. Normally, the grooving width of a cutting insert is based on the required grooving depth. However, the high system stability of the 2 mm grooving plate makes it possible to use it in applications where a slightly wider grooving plate is usually used. This enables considerable material savings to be made.
Special coating reduces tool wear
The cutting insert also stands out from comparable tools in terms of tool life: Gühring’s own NanoA coating offers excellent protection against wear and ensures consistently high machining quality.
Parting off in high-grade steel
Indexable inserts in a practical test
A field test in which we tested our product against a comparable product from a competitor also shows that the Gühring parting off plate leads to significantly longer tool lives. The customer used the grooving plate for parting off a turning part with a bar diameter of Ø26 made of high-grade steel. The tool life was increased from 700 to 1000 parting cuts and at the same time, higher cutting parameters resulted in a shorter component runtime.

Maximum tool lives in aluminium
How real progress emerges from challenges is demonstrated by Dörr together with Gühring: By using the PKD Diver from Gühring, the company from Sankt Augustin quadruples tool life, reduces tooling costs, and elevates the surface quality of its components to a new level.
System 208 enhances stability
Unattended night shifts without risk: Veile Feindrehteile significantly increases process reliability and tool life in stainless steel machining with System 208. The result: stable processes, less scrap, and more cost-efficient production.
Mastering VA threads with ease
Decommissioning nuclear power plants demands maximum precision—especially for stainless steel threads. Weisser Bärwinkel relies on Gühring’s Pionex to master even tough materials. The result: more stable processes, longer tool life, and higher productivity.
