High Quality Flat PDC Cutter
Publish time 2020-08-29 19:03
High wear resistance and strong impact performance for your premium PDC drill bits.
Flat PDC cutters are traditional type. It have stable ability and if the quality is good, it can drill any formations based on our recommendation.
The PDC cutter is composed of two parts. One is polycrystalline diamond layer and cemented carbide matrix. It is made by sintering fine diamond powder and cemented carbide substrate under ultra-high pressure and high temperature (50-70,000 atmospheres, 1400-1600 ℃).
Diamond composite discs are mainly suitable for drilling diamond composite disc drill bits (PDC bits) in soft to medium hardness and complex formations, and are mainly used for the extraction of oil and natural gas. The polycrystalline diamond grains have a complete D-D bond bonding microscopic feature, which makes the diamond layer have high strength, high hardness and high wear resistance, and at the same time has a good self-sharpness, a new cutting surface during wear. It will be exposed continuously to maintain the effective cutting effect on the rock.
As an international grade 1 PDC cutter, we do different test only only limited as below.
Abrasion (wear) resistance
Turning of a stone bar, typically granite.
Parameters - depth of cut approximately 0.5 mm, feed rate approximately 0.1 mm/rev and test time about 3 minutes; both dry and with coolant. PDC flank wear depth is measured.
Impact resistance (drop test)
Parameters - initial impact energy approximately 20J, repeated impacts are carried out to see if any spalling occurs. If there is no spalling then the impact energy is increased and the test sequence repeated. The result are typically reported as impact energy, number of impacts and spall area. It should be noted that the hardness of the impact anvil is crucial and it should be controlled.
We have different grade of PDC cutters. They can satisfy all PDC drilling bit design demand and any complex drilling condition.

Non-destructive testing
The total stress state of a PDC cutter is a combination of:
- residual stress caused by mismatch in thermal and elastic properties and
- operation stress caused by forces acting on the bit.
Residual stresses can be optimised by using FE analysis using a linear elastic model with thermal and elastic properties. An applied load analysis can be used to model spalling, chipping and heat generated cracking.

Turning of a stone bar, typically granite.
Parameters - depth of cut approximately 0.5 mm, feed rate approximately 0.1 mm/rev and test time about 3 minutes; both dry and with coolant. PDC flank wear depth is measured.
