The abrasive cutter for metallurgical cutting offers a cost effective high quality high powered motor, manual cutting action in the Z and Y axis. The large aluminium T slot table is able to accommodate very large samples for metallurgical cutting such as crank shafts for automotive applications . The large abrasive cutting wheel which is used for metallurgical cutting of upto 350mm offers 110 mm diameter cool cutting of the most difficult samples and long lengths with cuts of 100mm thick sections.
Manufactured of aluminium cast base with integrated recirculation coolant system offer robust and powerful construction to minimises vibration when used for metallurgical cutting. The FRP hood with large safety viewing window offer the operator full visual of the metallurgical cutting process and allows for operator control of the cutting speed and pressure.
Maintenance of cutting chamber with a cleaning hose is used for up keep of the machine. When the cutting is ongoing and safety lock secures the cutting chamber when cutting.

This is the most important part of the preparation of a micro sample as this is where the area of interest is removed from the main sample (replication may be required if the specimen is too big or it cannot be removed).
It is very important that the sample must not have its structure changed in any way by either Hot or Cold working or Mechanical manipulation, so care must be taken at this point of the sample preparation route.
The common types of sectioning are as follows:
The correct method must be employed for the material type, hardness, section and the requirement.
The most common type of sectioning by Metallurgists/Materiallographers is done by an Abrasive wheel (i.e. the Metcut range of machines) and the wheels are graded depending on the hardness of section to be cut (ie ‘A’ graded wheels for materials to 50 HRC, ‘AA’ graded wheels from 50 HRC to 60 HRC and ‘AAA’ graded wheels for materials over 60 HRC).
The size of the grain used is also an important factor, as this depends on the quality of the finish – some people use high precision wheels. The thickness of the wheel is also important. This can be reduced from the standard 1.6 mm of a 250 mm Ø to 1.0 mm. This promotes a good standard of finish and enables ‘difficult’ non-ferrous materials with a different bond to be used (i.e. for Titanium alloys). Another important factor is Cooling – i.e. a high flow jet or submerged sectioning.
The sectioning method commonly used for Composites, Varying Hardness, Brittle, Porous, Ductile and both Complex and Simple shapes is on Precision or Low Deformation saw using either resin bonded or diamond wheels. The resultant finish is of high quality and there is hardly any deformation, cracking on laminated sections or ‘plucking’ on brittle samples.
The use of a band saw and a hacksaw is now only used if the sample requires it and consideration must be made on the samples hardness, section and the finish required.
Once the sample has been correctly sectioned, then either the mounting or grinding operations can be started.
