Tooling Technology Comparison
Here as an example, are some key points regarding machining of an aluminium part using  Poly crystalline Diamond (PCD), Chemical Vapour Deposition (CVD) and Single Crystal Diamond (SCD).
A PCD turning tool could achieve a surface finish of between 1.30µm to 0.38µm. A CVD turning tool could achieve a surface finish of 1.30µm to 0.20µm. A SCD turning tool could achieve a surface finish of better than 0.1µm. With the PCD tool the part would require polishing to achieve a bright finish. With the CVD tool the part would require a lot less polishing time to achieve a bright finish. With the SCD tool the part would have a mirror finish without the need for polishing. A PCD tool could rough cut the part. A CVD tool could rough cut the part. A SCD tool is only suitable for finishing cut of less than 0.5mm. A PCD grooving tool would require the part to be de-burred after machining. A CVD grooving tool would require the part to be de-burred after machining (but less compared with PCD). A SCD grooving tool would require no de-burring of the part. A PCD tool is relatively cheaper to purchase than a CVD or SCD tool. A CVD tool is 2-3 times the cost of a PCD tool but came be run at higher cutting feed rates and in some cases with no lubrication. A SCD tool is 4 times the price of PCD but can reduce operating costs by removing de-burring or polishing processes.
Therefore each different diamond material has its place in machining materials.  Materials that diamond can machine . NON FERROUS MATERIALS For more independent information on diamond materials and their properties why not visit the DeBeers web site at   Element Six.com
