Worldia owns world advanced high precision grinding, lapping and polishing technology, laser cutting technology, testing technology and equipments. Over the years, we have been engaged in offering various services for famous manufacturers of PCD blanks, PCBN blanks, PDC cutters and cutting tools in Europe, America and Southeast Asia. Our services include grinding, lapping and polishing, laser cutting, finishing, rework and OEM/ODM service of super hard cutting tools.

Features of PCD/PCBN Blank Lapping and Polishing Service
1. The PCD/PCBN blanks are of flat surface and high quality.
2. Roughness: Ra≤10--15nm.
3. Common difference. Thickness of the PCD/CBN layer: ±0.1mm, overall thickness: ±0.05mm, diameter: ±0.05mm.
4. The C-scanner uses a high precision nondestructive test. It is used to test the combination firmness of the PCD/PCBN layer and the tungsten carbide layer, the internal structure of the PCD/PCBN and the thickness of the PCD/PCBN layer.

Features of the PDC Cutter Processing Service
1. Thanks to the unique laser cutting and grinding technology, the PCD layer will not be damaged by stress during processing.
2. Common difference. Thickness of the PCD/CBN layer: ±0.01mm, overall thickness: ±0.1mm, diameter: ±0.01mm, chamfer of the PCD layer: ±0.01degree.
3. The C-scanner uses a high precision nondestructive test. It is used to test the combination firmness of the PCD/PCBN layer and the tungsten carbide layer, the internal structure of the PCD/PCBN and the thickness of the PCD/PCBN layer.

Features of Laser Cutting and Drilling Service
1. Laser cutting features high precision of positioning.
2. The width of the kerf is only 0.02mm to 0.15mm.
3. Laser cutting features a smooth cutting edge and flat cutting surface. You cannot spot any breach from the cut diamond even if the diamond is put under a 100 times microscope.
4. Laser cutting has the advantages of high cutting efficiency and fast cutting speed.
5. The laser can realize curve cutting.
6. The laser can be used to precisely cut the edge of PCD/PCBN cutting tools. It can reduce the stress damage to the cutting tools during processing, prolonging the service life of the cutting tools.
7. Laser cutting and drilling machines can realize laser micropore processing.
8. The service of cleaning the tool bit and chamfering can save customers' preparation work before welding.

Features of PDC Cutter Rework Service
1. The rework service of PDC cutters can save energy, reduce emission and turn waste into wealth. Waste PDC oil drills occupy capital and pollute the environment. Supower rework service of PDC cutter can turn the waste into wealth. It not only saves raw material cost for the PDC blanks manufacturer, it reduces the consumption of valuable metal, water and power.
2. The rework service of PDC cutters features nondestructive testing, so it can avoid the blindness of rework. The C-scanner uses a high precision nondestructive test to test the combination firmness of the PDC layer and the tungsten carbide layer, the internal structure and stress amboss of the PDC, to scientifically judge the recycle value of the PDC blanks. We will arrange the rework technology according to the damaged condition of the PDC blanks. In this way, the blindness of rework can be avoided.
3. The rework service of PDC cutters can maximize the use ratio. With the comprehensive utilization of various technology, including laser cutting, grinding and polishing and special machine processing technology, we can further increase the use ratio of old PDC oil drills.
4. The rework service will not be affected by the electrical conductivity of PCD material.
