"A dream come true"


The more time required to machine components and the more tools needed, the greater the wish to save on work steps and thus tools. At Knorr-Bremse,  KOMET®  has made a dream come true with the new indexable insert technology of the  KOMET® PreciKom,  saving on tools and machining time in the machining of calliper frames.

Knorr-Bremse is a leading global manufacturer of brake systems for rail and commercial vehicles. The diversity of the components the company produces is accordingly wide. For example, the company produces calliper frames from cast iron (GGG-60), which can take between 1.5 and 2 hours to machine depending on the variant. The large variety of tools required for this gives rise to a wish to improve machining processes and find possible ways of saving on tools. The technical field service of the  KOMET GROUP  has made this dream come true with the new indexable insert tool  KOMET®  PreciKom.

With one bore diameter - the most frequently required - (60mm), the new 
KOMET® PreciKom  removes the need for the rough turning step required to date. Following the continuous drilling step, the fit is now finished straight away. This is made possible by specially developed cutting element geometry with support chamfers. This means that there is no need for the usual guide strips on the base body and ensures the required roundness and concentricity. The high-performance  KOMET® PreciKom  indexable insert drills enable a significantly greater allowance. According to  KOMET®,  drilling qualities of up to IT8 can be achieved at cutting depths (ap) of 3 to 4 millimetres (allowance of 8 millimetres).

A further advantage appreciated by Knorr-Bremse arises from the indexable insert technology itself. In comparison with the tools traditionally used for reaming - with brazed flutes - these tools are significantly more flexible. In addition, indexable inserts are more quickly available and enable better adaptation in line with the machining task at hand thanks to the cutting material and coating variants. With the 
KOMET® PreciKom  , the innovative indexable insert fine adjustment process allows each individual indexable insert to be adjusted with µm precision.
