  1. Ways for Machining Graphite Successfully It can be a challenging task to machine graphite. This problem becomes bigger if you are not ready to work with the messy and unique properties of this element mineral. The following lines will throw light on the concept of machining graphite correctly and successfully and provide answers to some of the important questions related to this process. • Take Care of Contamination- First of all you should always ensure that synthetic graphite is machined dry instead of using liquid coolants. If you use coolants while working with this material it will produce an ‘abrasive slurry’ at time of coolant combination with the finer bits of the material’s dust and chips. It is also possible that the coolant fluid will permeate within the material through its open pores. Such a contamination can lead to problems when this material is used in any application requiring the use of the inert properties of the material. • Remove Excess Moisture- Next, make sure that the material is dry before you start the machining process. In case the stock of raw material has been exposed to water or stored outside you have to bake it to remove all excess moisture. The dust and water can cause‘abrasive slurry’ that will reduce the life of your tool dramatically. Such an issue can be clearly observed while cutting any wet graphite material on band-saw. • Maintain Tool Sharpness- Also, make sure that the machining is done using very sharp tools so as to prevent the edge-chipping or particle pull-out. As soon as the cutting tool loses its sharp edge the

This happens because the tool is dull and is not cutting but pushing the material. The above-mentioned concepts will help in machining the material properly and ensure that the entire process takes place safely and successfully.
