Domed type PDC bits front teeth are non-planar cutters, the back teeth are conical teeth, the front row tooth composite plate adopts convex ridge structure design, which can effectively improve the impact resistance and wear resistance of the bit. Rear row compound conical teeth are conical cutting elements, which can effectively share the drilling load of the front row main cutters by participating in formation fragmentation, which is conducive to protecting the front row cutters and greatly improving the service life of the bit.
When the PDC bit works, first the raised edges of the front non-planar composite touch the formation and pre-break the rock. Then the composite plane is partially ploughed to compound break the formation rock. This design increases the resistance ability of the diamond composite and transforms the main cutting force from a curved plane to a large angle cutting, which requires a lower cutting force.
Due to thicker diamond layer and proprietary diamond particle distribution and mixing technology, it also obtains better frontal impact resistance, compared with conventional PDC composite, it has stronger rock breaking ability and better wear resistance. At the same time, the rear-row conical teeth exert higher point load on the formation than the conventional flat PDC composite plates, so the formation with high compressive strength can be broken more effectively by the combined mechanism of plough scraping and shearing. As the force fed into the formation passes through its axis, it has a more balanced lateral force, which effectively reduces the lateral and longitudinal vibration of the bit and prolongs the bit life.
In addition, MoreSuperHard also provide Cylindrical Diamond Grinding Wheel for PDC cutters
High efficiency, Good self-sharpening, Excellent surface finish, Long service life
? "Good news the third trial wheel performed successfully we completed four blocks with 2.5mm removal of Diamond cutters, eight grinding passes in total, the operator was more than happy with the quality of the finish”. -----from UK client of MoreSuperHard
? " It was very similar to 3M's grinding wheel but our price is a little better so it makes better sense". -----from UK client of MoreSuperHard

In modern manufacturing, tungsten steel (hard alloy) is widely used due to its high hardness and wear resistance. However, the requirements for tools when processing tungsten steel are extremely high, especially the selection of suitable grinding wheels is crucial in the grinding process. This article will share the case of us providing customers with high-quality grinding wheels and successfully solving their processing problems.
SG grinding wheels are suitable for grinding carburized steel. Their high hardness and self-sharpening properties enable them to effectively grind the high hardness surface of carburized steel, while low heat generation and good heat dissipation reduce thermal damage during the grinding process. In addition, the wear resistance of SG grinding wheels also helps to extend the service life of the grinding wheels and reduce grinding costs.
