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.

and then determine the heating mode and the holding time after reaching the sintering temperature. 1 Sintering temperature: For a certain product, since the binder has been determined, there is a certain range of sintering temperature. This range is generally within plus or minus 100 °C of the optimal temperature sintering point, and the sintering temperature is usually around 2/3 of the primary bonding point of the bonding agent, ie T'W ratio is 2/3.  Where. The actual sintering temperature is determined by the test burning block. The first group of blocks is determined according to the above temperature. After the test, the color, surface condition, and final product of the test block are observed. It is judged whether the burned or under burned, and the second is determined. The sintering temperature of the test block. Perform the third and fourth groups of blocks in the same way  The test burns until a suitable temperature is obtained. 2 Sintering time: Sintering temperature and sintering time are a pair of related parameters. Appropriately increasing the sintering temperature can relatively shorten the holding time of the sintering point, but if the control is improper, the product will be deformed, grain growth, and even segregation, affecting product quality. When the sintering temperature is low, it must be extended  The soaking time of the sintering, but the production efficiency is low, if the control is improper, it will cause the product to burn out. Sintering temperature is high and low, the temperature difference can not be too large, generally about 20 °C. In addition, the sintering time is also related to the weight, thickness, and diameter of the product, as well as the total surface area of ​​the product. Time T can be expressed as (7-62).  In general, when the binder type and sintering furnace structure are determined, the product size is small and the total surface area is large, when sintering       Can be shorter. 3 Cold-pressing-sintering curve: Although there are many types of binders and products, the composition of the cold-pressing-sintering curve is basically the same. As shown in Fig. 7-62, the temperature, insulation, and cooling are divided into three major parts. This is due to the nature of liquid phase sintering. Before 500°C, it is sintered  The first stage of the process. That is, there is no fundamental change in the properties of the saw blade body. For the bronze binder products, the temporary activators added during the forming process are volatile substances. The metal powders used are all reduced. The liquid phase formed at low temperature is very low. Therefore, the temperature increase will affect the performance of the blanks. The impact is not significant, so this phase is adopted     Diamond Tip Core Drill Bit Segments.  The Figure 7-62 cold pressure sintering curve   Freedom from heat will not affect product quality. Insulation at 500°C has certain advantages for large-size products: a. Let the oxides of the powder particles in the blank be fully reduced under the reducing atmosphere, so that more active atoms are generated on the surface of the powder particles for the sintering of the next step. Good preparation:  b. The uneven temperature in each part of the mountain due to rapid temperature rise is balanced, so that the stress in the billet is eliminated. c. As the holding time continues to increase, the amount of liquid phase also increases, and begins to dissolve the phase material. For small size products, it can be directly up to the sintering temperature (dotted line in the figure  Shown >. In the section from 500°C to the sintering point temperature, the main change in the green body is the significant increase in the liquid phase. The powder moves under the surface tension of the liquid phase and the rearrangement tends to complete, while the high-energy part of the powder body (such as the sharp corners) , edge, etc. > Largely dissolved in the liquid phase, so that the solubility tends to saturate  State, when the body has a significant contraction. It is very important to keep the temperature at the sintering temperature, which can make the changes in the parts of the blank to balance,
