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 at the same time the saturation begins to precipitate to the low-energy parts of the surface of the powder particles. At the end of the insulation, the surface of the powder particles is dissolved on the one hand and crystallized on the other hand.  Dynamic equilibrium, and this dynamic equilibrium process continuously extends into the interior of the particles as the holding time increases. At this time, the liquid phase of the blank has increased, so excessively prolonging the holding time will increase the amount of liquid phase, easily causing segregation of low-melting components and affecting the sintering quality. The cooling process is a liquid-phase crystallization process and therefore an integral part of the sintering curve. The cooling speed has a certain influence on the hardness and strength of the product, mainly related to the type and size of the product. When the cooling rate is fast, the crystal grains are too late to grow, and the crystals are smaller and the green body is stronger.  The degree of increase accordingly. At the same time, rapid cooling and balanced cooling are also different. For bronze alloys, the α solid solution has a tin content of 15% when cooled in an equilibrium state, while the α solid solution has many green bodies with low strength and good plasticity; when cooled in an unbalanced state, the α solid solution area is greatly reduced.  , β phase and more than 5 phase p makes the body brittle, and this property is not necessarily beneficial to the saw blade. Rapid cooling will cause large stress in the blank. When the Sn content in the binder is high, special attention should be paid, because the binder itself is brittle and under large stress.  , prone to cracks. Although the tapping temperature is not included in the sintering curve, it is more important than cooling speed in a certain sense. For the cutting blade, due to its large area, thin thickness, and high temperature at the time of oven temperature, it will cause serious warpage, so it needs to be cooled to near room temperature before it can be released.     Section 6 No-pressure Impregnation Method for Making Diamond Drill Bits and Reamers  The basic process for making diamond tools without pressure is as follows: Firstly, the quantitative skeleton powder (usually sintered carbonized pigeons) is put into the sticky  Diamond Drill Bits For Drilling Stones  In a diamond mold with good diamond, put the drill steel into rest, and after proper vibration, the skeleton powder will reach the required density: Then, the appropriate amount of nodule metal (mostly bronze and bronze cast alloys) will be installed in the box type electric furnace. Sintering: When a certain temperature is reached, the metal of the nodule melts and penetrates by capillary action  In the skeleton powder, it is formed into a pseudo-alloy, which can firmly enclose the diamond and form tightly with the drill body. This method is more used for oil bit production. First, the pressureless impregnation method to make diamond drill bit  The pressureless impregnation method is a method for manufacturing a diamond drill in the late 1960s. It is characterized by the fact that no pressure is applied when the drill bit is powder-sintered, thereby facilitating the production of complex-shaped drills such as Christensen of the United States. Diamond Products mainly uses this method to produce oil and gas  Well drill. Since the 1970s, many diamond drill bit manufacturers in the world have introduced the company's patent for impregnating impregnated table bits. The process flow for the pressure-free impregnated surface insert drill is shown in Figure 7-63.       Fig. 7-63 Process Flow Chart of Pressureless Impregnated Table Bit  Now taking the manufacture of a comprehensive drill bit as an example, a brief description of the manufacturing process of a pressureless impregnated bit is given. Graphite mold After the graphite mold has been made by car, it is firstly struck on the bottom mold (including diamond position and waterway position), as shown in Figure 7 - 64. After the bottom mold is scribed, the bottom mold is turned on, see Figure 7 - 65.
