What Is PCD Reamer

With consumer plenarily communication, Deepens know consumer requirement, According to consumer requirements, including accuracy, roughness, working life. We will fabricate qualified PCD reamers for different applications.

В основном она включает в себя изготовление корпуса инструмента и стружечных канавок. Производственная обработка включает в себя токарную и фрезерную обработку с ЧПУ, цилиндрическую шлифовку, 5-осевую обработку с ЧПУ, изготовление канавок и термообработку.

By software calculation and layout, the laser machine can cut the PCD disk into related small blades, the laser cutting can make sure each size is consistent, which is convenient for the next step.

Before brazing, we will stick the PCD blades to the brazing grooves with silver solder, then put them into a vacuum brazing furnace and bake for 20minutes at a temperature of 800 degrees. The process can ensure the silver solder is fully melted and stuck closely. Therefore, the tipped PCD couldn’t fall off even if working in high-speed turning or strong hitting.

5-axis Vollmer Wire Cutting is one of the best ways to produce PCD forming cutting tools. Its excellent performance, handleability, and stability help us finish all kinds of complicated PCD reamers works. The cold-oil processing environment significantly improves the cutting blade finish, and the surface finish can reach Ra0.4. We have three sets of Vollmers to offer service for all projects.

Иногда при обработке алюминиевых отверстий требуется гладкость. Поэтому необходимо отшлифовать режущую кромку. С одной стороны, этот процесс может значительно улучшить качество обработки PCD, но с другой стороны, менее острая режущая кромка уменьшает вибрацию стенок отверстия, что наиболее важно для обеспечения точности в пределах 0,002 мм после цилиндрической шлифовки.

Once we have finished the Wire Cutting or grinding process, we will do a complete test on the tool Zoller, including every diameter, angle, and arc. All of them need to be checked by the program before passing to our QC. Some cutting tools with HSK and BT shank need to do a dynamic balance test to ensure the concentricity of the PCD reamer is within 0.002mm when rotating.

It is the final step. According to the special needs of customers, we will provide surface sand-blasting or oxidation treatment for the PCD reamers, The purpose of this process is mainly to ensure the surface looks good and rust prevention. Meanwhile, the laser marking for model information is available for different demands.
