Purification process of the ultra-fine diamond powder grading

Particle size and distribution width of two key technical indicators are in line with international advanced standards diamond powder classification technology. The paper also explores the purification process of the ultrafine diamond powder grading, purification and grading will combine. The reagent-treated fine powder was washed by , adding a certain proportion of the surface active agent, and observed under the microscope. By a large number of experiments, we developed a new purification method for fine diamond powder: the dedicated reagent strong  synthetic diamond , prepared open diamond agglomerates formed during impurities, which is due to high temperature and pressure such that the resultant diamond single crystal particles and the reaction raw materials, additives, catalysts and other  abrasive grinding  together and form, thus increasing the contact area of ​​the reagent, the effect to improve the decomposition of impurities, finally obtained purified to more than 99.95% ultra-fine diamond powder.

Processing of heavy large diameter thin-walled workpieces CNC machining aspects of our strengths

Processing of heavy large diameter thin-walled workpieces CNC machining aspects of our strengths, including large pitch trapezoidal thread processing is particularly prominent. We use imported carbide coated tools, make full use of CNC lathes lateral approach and alternate feed function to complete processing of thin-walled workpieces  synthetic diamond  thread. Have introduced a large number of world advanced CNC machine tools, high-speed five-axis machining centers, CNC machine tools in the introduction of these advanced and promoted, in the design, manufacture of  cutting tools  the original two-dimensional to three-dimensional design changes, product development from the ground to space products , diversified products. Thin, contoured, complex, difficult materials and other parts, is often encountered in routine work. In the CNC production process of many factors affecting the quality of products: machine tool performance and accuracy, processing steps, processing parameters, and trajectory of the tool, a reasonable method of clamping, cutting fluids, tool selection.

Conductor roundness measuring mainly by workers and frequent stops rolling wheels by adjusting the position of the right or the distance to complete

The advantages and disadvantages of ordinary carbide dies circular compacted stranded conductor production, was first layered twisted after rolling through multiple sets of  abrasive wheels  forming. Conductor  abrasive grinding  measuring mainly by workers and frequent stops rolling wheels by adjusting the position of the right or the distance to complete, require production workers have a higher technology and rich experience.  Diamond blade , this makes the control of the artificial stranded conductors are still generated when angular, round surface is poor, affecting the electrical properties of the cable, increasing the likelihood of breakdown of the cable. Later, as people used a circular carbide drawing die constant awareness will be applied on the conductor strands pressed molding process.

Surface smoothness directly affects the quality of the conductor shield layer

Rated voltage XLPE insulated power cable conductors usually circular compacted stranded conductor, the surface smoothness will directly affect the quality of the conductor and the cable shield using life.  synthetic diamond  pressed in two ways: one is  abrasive wheels  pressed; Another is pressed mold pull pullout. Pressed by the cable conductor molding pressed after drawing, bright surface, precise size. Based on the nano-diamond composite coating die and pressed analysis and comparison of ordinary carbide dies that nano-diamond coating pressed mold has long service life, high production efficiency, low manufacturing cost and quality advantages.

Tool and mold applications is extremely frequent

In the process of manufacturing machinery and equipment , tool and mold applications is extremely frequent , improve the working life of the tool and die , it can effectively reduce costs and improve labor productivity and reduce labor intensity . So, in what way to improve the performance of the tool and die is the easiest and most effective of synthetic diamond  and engineers first thought was coating technology , that is, to the original tool or mold as the substrate , coated with a hard wearing , low friction coating , you can have a multiplier effects. In a variety of coatings , is naturally the most desirable diamond ( diamond ) coating it. If you can put the magic diamond coat , the tool and mold can be more functional layers on the building. Diamond : Fascinating not only due to the beautiful synthetic diamond powder  diamond ( diamond ) is extremely precious stones , in people 's eyes flashing light it is often a symbol of status and wealth . However, there are many excellent  abrasive wheels  and chemical properties known : it is the highest hardness , thermal conductivity, preferably , also has excellent optical performance , not only with ultraviolet light, visible light, infrared light , but also by X-ray microwave ; diamond excellent chemical stability , capability at room temperature almost all chemical reagents ;

Diamond cutter running direction (direction scribing)

Grating ruling machine known as " precision machinery of the King" , its main working principle is to use the diamond cutter in a raster scored on an aluminum substrate having a certain shape groove array. It includes two orthogonal directions of motion , the direction of the grating substrate ( indexing direction) and the running direction of the diamond cutter ( scribing direction ) . Movement in both  synthetic diamond  precise fit , forming a periodic groove , grating ruling machine working process diagram depicts the process of the grating , the grating with the movement of the substrate , diamond tool within the specified time  cutting tools  and fall, lift off the knife process takes as much as possible to keep running stability , otherwise, it will cause the grating substrate and scored rail vibration , resulting in deterioration of the quality grating ruling lines . Lift off the knife speed and height should be adjusted according to the technical  grinding wheel  of real-time , off the knife position should reach micron level precision . In addition, the characterization before , according to the grating ruling process requirements , the need for preparation of diamond tool to adjust the adjusting work completed by the craftsmen , which requires lift off knife mechanism can be controlled manually . Traditional grating ruling machine uses a mechanical lift off knife mechanism , there is poor stability, mechanical structure complicated maneuver, precision and low defects , which directly affect ruled grating quality and production efficiency .
