Special purpose cutting tools
      for producing specimen


So that the demands made on accuracy, shape and service life of the cutting edges are achieved, VHM saw and profiled cutting blades for QC and specimen applications are costly to produce and grind. For this reason this category of tools is more expensive than comparable standard types.

To achieve to a great extent freedom from burr, the ideal settings for speed and feed have to be found by experiment. These values depend on many factors, so it is not possible to give any standard values here. Normally, a few trial cuts are sufficient.

If plastics with a filling, such as glass or carbon fibres have to be processed, we recommend that you first contact our laboratory.

If required we make test cuts for you in order then to develop particular cutting geometries with which you can achieve the best cutting qualities.
