Line 594:
**** Depths of cut and feed rates should be low, ideally <0.1mm
**** Surface speeds around 75-150 m/min, the harder the material the slower the cut but go as fast as possible for any given job
*** Diamond tooling exists for use in hard non-ferrous materials and highly abrasive materials
**** Diamond tooling comes in PolyCrystaline Diamond (PCD) which is very expensive - more so than CBN, and MonoCrystaline Diamond (MCD) which is eye-wateringly expensive.
**** PCD is very, very hard, MCD is the hardest tooling material known to exist.
**** Diamond tooling cannot be used on ferrous metals as the carbon from the diamond will dissolve into the iron
**** Diamond can be used to turn exotic materials such as aluminium superalloys, nickle superalloys, precious metals, tungsten carbide and carbon fiber
**** Maximum work hardness for diamond tools can go as high as 70HRC although wear increases above 60HRC
**** Cutting speeds can range up as high as 1000m/min or as low as 10m/min depending on the hardness of the work
**** Depths of cut and feed rates should be low, ideally <0.1mm, however the very high surface speeds used with PCD tooling will still result in rapid material removal rates
* Workholding using all chuck types and recovering concentricity
* Using reamers
