Polycrystalline Diamond Cutter Bearings and Long PDC by Diffusion Bonding

1. AMTmetalTech Quality PDC Brazed Precision Diamond Bearings

1.1. AMTmetalTech Quality Polycrystalline Diamond Cutter PDC Diamond Bearing Description

AMTmetalTech Quality Polycrystalline Diamond Cutter PDC bearings are made by precision brazing the PDC cutters on steel bases and then make the precision machining to the whole workpiece containing the PDC cutters.

1.2. AMTmetalTech Quality Polycrystalline Diamond Cutter PDC Diamond Bearing Advantages

AMTmetalTech strictly controls the temperature on the diamond during brazing to avoid the decomposition of the diamond.

AMTmetalTech’s high precision brazing makes the Polycrystalline Diamond Cutter PDC on the bearing has the precise location and all the Polycrystalline Diamond Cutter PDCs are on the same level.

AMTmetalTech Quality Polycrystalline Diamond Cutter PDC has excellent abrasion resistance, impact resistance, superior hardness, good thermal conductivity and thermal stability. It’s also suitable for highly corrosive environments and greatly improve the service life of the bearings.

1.3. AMTmetalTech Quality Polycrystalline Diamond Cutter PDC Diamond Bearing Applications

AMTmetalTech Quality Polycrystalline Diamond Cutter PDC bearings can adapt to severe working environment and bear the grinding of drilling fluid, high load, high speed, strong impact force in drilling process. AMTmetalTech Quality Polycrystalline Diamond Cutter PDC bearings have high abrasion resistance, high corrosion resistance etc. and are very suitable for the oil field. 

2. AMTmetalTech Quality PDC Diamond Long Cutter by Diffusion Bonding

2.1. AMTmetalTech Polycrystalline Diamond Cutter PDC Diamond Long Cutter Description

AMTmetalTech Quality long special-shaped Polycrystalline Diamond Cutter PDC cutter is connected by diffusion bonding betweent PDC and Hardmetal. The temperature of diffusion bonding is below 700℃. Through the long time of high pressure contact, the hardmetal joint has been formed by atomic diffusion. We can connect PDC Polycrystalline Diamond Cutter on drill bits, tool shanks and other hardmetal substrate.

2.2. AMTmetalTech Polycrystalline Diamond Cutter PDC Diamond Long Cutter Advantages

Low diffusion temperature under 700℃ has little harm to PCD diamond layer.

High precision Polycrystalline Diamond Cutter PDC to substrate can guarantee the dimensional tolerances.

The Polycrystalline Diamond Cutter PDC to substrate shear strength can be in excess of 400MPa.

High performance Polycrystalline Diamond Cutter PDC bit design has high penetration rate in mining.

The Joint Strength between Polycrystalline Diamond Cutter PDC and hardmetal is stronger than the hardmetal. The broken will be occurred in the hardmetal rather than at the joint.

The Polycrystalline Diamond Cutter PDC to substrate has no stress concentration, which prolongs bit’s lifetime.

2.3. AMTmetalTech Polycrystalline Diamond Cutter PDC Diamond Long Cutter Applications

AMTmetalTech Quality Long Special-shaped PDC Polycrystalline Diamond Cutter is mainly used for high performance drills with high strength requirements which brazing is not satisfied. The Polycrystalline Diamond Cutter PDC bit made by diffusion bonding is widely used in oil mining for the excellent performance. Also we provide diffusion bonding service for customers.
