Impact Resistance Test
The initial impact energy is 40J for 10 impacts. If there is no damage, the energy is increased by 10J for another 10 impacts. The impact energy and frequency increase incrementally until the PDC cutters fail.
Wear Resistance Test
The depth of penetration into the granite for the tested item is 1.25 mm. The rotation speed is a constant linear velocity of 107 m/min, and cutting continues at a constant speed until PDC cutters fail.
Thermal Resistance Test
PDC cutters placed in tubular furnace, heated for 15 mins under air, then cooled for 15 mins. Cyclic thermal shock testing repeated 5 times/temp level without damage. Temp increased by 25 degrees each time until product failure.

We focus on the development, production, processing and sales of PDC(polycrystalline diamond composite) tools.
PDC tools are widely used in oil drilling, geological exploration, mechanical processing, wood processing and other fields.
It is recommended to consult a professional drilling engineer or PDC composite manufacturer to select a PDC composite shape suitable for a specific formation, considering formation hardness, rock type, drilling depth and other factors.
PDC composite sheet should be kept clean during use to avoid impurities such as metal falling objects affecting its performance. At the same time, the wear of the composite sheet should be checked regularly, and the composite sheet with serious wear should be replaced in time.
The lead time of PDC composite sheet products is affected by many factors such as production scale, order volume and production process. Generally speaking, manufacturers will provide specific delivery times according to customer needs.
We have high-precision machining equipment and professional technicians to ensure that the machining accuracy of PDC tools can meet customer requirements.
Yes, we accept samples from customers for testing or trial in order to better understand customer needs and product performance.
We use professional packaging materials and methods to ensure that products are not damaged during transportation. Transportation mode can be selected according to customer needs.
We have a professional research and development team, committed to the development and innovation of PDC tools and diamond grinding wheels.
