Packaging and Shipping for Diamond Drill Bits

Inner packing: a diamond drill bit is covered by antirust paint and plastic, then packed in a paper box; outside packaging is according to the transport way, if by air, we recommend carton package which will reduce the weight; if by sea, we recommend crate which is seaworthy. Other packaging is also available upon your request.
Urgent order with less weight or samples, courier service is recommended;
Normal (regular) order which weight over 45kgs, delivering by air is recommended;
Big diameter saw blades or heavy weight products, shipping by sea is recommended.
Edgestone will offer advices according to the actual order requirements.

3. Assembly Figure 7-66 shows the assembly of the die for pressureless impregnation. According to the design of the carcass height, thickness calculated skeleton powder into the mold, edge edge vibration, in order to achieve a given loading density; then put the steel body into the mold, and to ensure that the carcass and steel body have a higher Concentricity: Then load the appropriate amount of dip  The stained metal and shed sand are finally covered with graphite caps. In order to prevent corrosion of the steel body, a layer of Al 203 glue can be applied to the mold wall. 4. Sintering Sintered drill bits typically use a silicon-carbon rod high-temperature box type electric furnace. To prevent oxidation of diamond and carcass components, it is necessary to put carbon in the graphite mold Chips or protective atmosphere. The sintering temperature must be soaked in the molten metal    Figure 7-66 Full Drill Die Assembly Diagram 1. Graphite cover: 2. Shed sand; 3. Stone impregnated cover; 4. Impregnation metal: 5. Heart mold; 6. Steel body; 7. Fetal skeleton powder; 8. Diamond; 9. Graphite bottom mold    Into the matrix powder, the impregnated metal is infiltrated into the matrix powder to densify the matrix. The sintering temperature depends on the impregnation metal melting point, which is generally 152°C higher than the melting point of the impregnated metal. Keep warm for 30 50min. 5. Machining Care should be taken in the processing of the steel body thread to ensure the perpendicularity of the thread to the end of the carcass and the concentricity of the outer diameter of the carcass.  Second, pressureless impregnation method manufacturing reamer  Synthetic diamond sintered body reamer is an essential tool for diamond small-caliber geological prospecting. It is a diamond-assisted drilling tool made of a small-diameter synthetic diamond sintered body as a cutting material and a pressureless impregnation method. The pressureless impregnation method for manufacturing a reamer is a form of powder metallurgy in which a given amount of skeleton powder is charged into a reamer mold adhered with a sintered body, and the skeleton powder reaches a prescribed charge after proper vibration. Density, put into the steel body, and then install a quantitative amount of the bundling metal in its upper part. In sintering  During the process, when the sintering temperature is reached, the nodule metal is melted, and the heat of the metal and the steel body is exchanged by capillary action to make the carcass welded to the steel body. After the furnace is cooled, the carcass can achieve the required performance, including mechanical strength, hardness, and firmness of diamonds. 1. Requirements for skeleton powder According to the working condition of the reamer, the following requirements are imposed on the skeleton powder. (1) Skeleton powders that make up the hard matrix of the carcass are required to be composed of different particle sizes and uniformly distributed in various particle sizes so as to obtain a fetal rest with good mechanical strength, wear resistance and appropriate hardness. The Price Of The Diamond Drill Bit . (2) Strive to have a certain shape of the powder particles, so that the density of the powder particles can be controlled within a narrow range, and each time the amount of loading is reproducible, in order to ensure good impregnation performance and ensure the quality of the carcass And dimensional accuracy. (3) Skeleton powder particles must be dense and void-free, so that the density of the carcass after sintering reaches or close to the theoretical density, ensuring excellent mechanical properties of the carcass. (4) It is required that the skeleton powder does not produce a certain powder melting at the sintering temperature to make the skeleton volume significantly contract, so as to ensure that the performance of the various parts of the carcass reaches the established requirements. (5) It is required to have good wettability between the skeleton powder and the known metal. Based on the above requirements,
