Product Description

PDC Cutters Introduction:
Wuhan Reetec Diamond Co.,Ltd is a leading manufacturer specialized in diamond composite materials R&D , design and production . Our TD cutter is the most advanced PDC cutter at present

Material : PDC-Polycrystalline diamond compact is composed of Polycrystalline
Diamond layer and tungsten carbide substrate.
 
The Polycrystalline diamond layer possessed extremely high hardness and
abrasion resistance whereas the tungsten carbide substrate would greatly improve
the malleability and ability of whole composite.
 
Diamond thickness is increased to 1.8mm -2.3mm

1. The impact strength and Wear resistance is improved
2. Heat resistance is improved to 750 centigrade degrees while previous ZM is 700
3. Long lifespan and stable performance

Features:

1. The diamond powder is selected in a higher degree.
2. Use a new type of tungsten carbide, which improved the strength character of bonding. 
3. The claws of the interface are changed to be net-grooves-shaped which formed by 20 straight vertical grooves, and the depth of the grooves are shallower. 
4. Improved the interior structure of the sintering cell that makes the pressure and temperature to be more uniform.
5. Use new super heat-resistant metal, to avoid being contaminative during sintering. 
6. Amended the sintering processing, and improved the bonding strength of the diamond-diamond key among the diamond layer. 
7. Increase the content of diamond, and increase the thickness of diamond layer up to 2.0mm

Applications: As gauge protector and drilling cutters inserting for rock cutter machines and coal mining core drill bits for geotechnical (mining, water well drilling) tunneling, quarrying, construction and machinery aspect.)
Quality ISO 9001:2008
Packaging: plastic box

Quality Control
Reetec achieved ISO certification in 2010. REETEC'S certified quality program ensures the best possible product consistency and uniformity for each of our product, and guarantees the delivery of defect free products and 100% customer satisfaction.
REETEC has set up a new performance test laboratory, and uses world-class testing and inspection equipments both for product development and for quality control. We subject our cutters to rigorous testing, to ensure REETEC cutters meet the highest quality standards.


Vertical Turret Lathe (VTL) Heavy Wear Test
REETEC's premier test apparatus is the large VTL used for performance and high-energy testing of PDC cutters.
The VTL machine is equipped to perform both wet and dry PDC tests, in granite and composite cement samples. As the PDC cutter cuts through miles of granite, we monitor temperature and cutting forces, and measure cutter wear volume periodically and at the end of the test. This allows us to evaluate cutters' aggressiveness, efficiency, abrasion resistance and thermal stability.

Impact Resistance Test
The drop impact test evaluates the impact strength of our PDC cutters. This test emulates the type of loading that might be encountered when the bit transitions from one formation to another or experiences lateral and axial vibrations.
Drop impact testing is part of PDC development. It screens cutters to make sure they are not too "fragile". While this is an industry-standard test, it should be noted that the drop impact test does not duplicate all impact-related downhole conditions. Other test development efforts for impact resistance testing are underway.




Simulated Brazing Test
Simulating the actual brazing environment, we run three simulated brazing cycles for thermal proof testing. After each brazing cycle we check for cracks and delamination using dye-penetrant testing and ultrasonic C-Scan. Brazing tests insures that the customer will not experience problems in brazing PDC cutters into bits, and in repairing PDC bits.
