This artical tell you how to retip/weld diamond segments on core barrel. Worn out diamond core drill bit segment or damaged core drill bit do not always need throw away. Although ChinShine can't provide a re-tipping service at your side, we make diamond core drill bits, diamond segments and provide the silver solder, magnet holder, flux, and welding machine, so you can do the welding yourself.  We can make various diamond segments for fast, free drilling in concrete and stone, all kinds of bond and formula for your choice, such as arix diamond segments, dimple diamond segments, roof diamond segments, turbo segment..... The high quality polycrystalline diamonds ensure excellent drill speeds and footage. Before re-tipping, check the following: • Check the core bit thread to see if it is damaged • Check the barrel body to see if it is too thin or bend • Check the outside diameter of the barrel for roundness or damage If all these are serviceable, retipping is possible. Your core body can be brazed by your local saw doctor or sharpening outlet, or any engineering workshop that offers brazing services. If you want to re-tip diamond segments on core barrel by yourself, you will need these tools: Heat source, gas or high frequency welding machine Silver  welding Solder Flux Diamond Segments Magnetic welding holder Silver Solder: Use the right brazing rod or silver solder. You need silver solder rods, cadmium free, with 40% to 45% silver. One silver welding stick will usually do 10-20 segments, depending on your skill. Flux: A fluxing agent is required for all brazing jobs. The flux removes oxides from the base material and prevents oxidation during the heating process, thus enablng the free flow of the solder, you can find the cheap flux at your local market. Diamond Segments: Obviously, we make all kinds of premium quality diamond segments for your choice, such as arix , roof, turbo, dimple... . Here are the diamond segments quantity per core bit: When replacing segments, just count how many you need. For crown segments, we just need an accurate diameter of the crown. You will then need to pick the style of segment you want: 1. Remove remaining diamond segments if replacing all segments (use heat and pliers to melt the solder), otherwise check existing segments if replacing lost segments only. 2. Carefully clean the barrel welding surface with an angle grinder. 3. Gently clean the bottom and end surfaces of the segments a little with a 100/120 grit grinding wheel. Try not to expose any diamonds  as this will reduce the strength of the brazing, possibly with the risk of segment loss. 4. Add flux to the brazing surfaces of the diamond segments and the barrel and let dry. 5. Check the thickness of the segments and put your brazing magnet tools on the inside of the core. Choose the magnet setting so that the segment clearance on the outside will be about twice the clearance on the inside. This normally means using a 0.5mm magnet clearance wh...

Diamond wire saw rope is available in a variety of types, each with specific advantages and ideal usage scenarios depending on the nature of the project, the variables affecting the formation of diamond wire segment, and its individual features. Diamond wire saw cutters differ from others, such as the bandsaw, by using abrasion instead of saw diamond teeth. Thanks to the hardness of diamonds, the abrasion technique can be used to cut through almost any material that is softer than the diamond abrasive. The process also produces less kerf and wasted materials when compared with conventional solid blades. The wire cutter also allows circular cutting on all sides, preventing the wire from getting pinched and is therefore an effective method of resisting compressive forces while cutting a wide range of materials. Vacuum Brazed Beads To improve the quality of the braze bond, vacuum brazed beads are produced in a brazing oven. The braze, often known as "paste" is a combination of various metal alloys. Some titanium alloys are used in active brazing, that when cured produces carbides. Vacuum brazed diamond beads is a brazing method that fixes the diamond powder on the bead matrix. This method is more environment friendly compared to electroplated wires which causes pollution. Vac...

In the 1990’s, in order to solve the processing problem of large size silicon wafer, jigsaw machining technology are widely used to cut large size silicon wafer into blocks and pieces in the international marketing. Early jigsaw machining technology applied bare wire and free abrasive. In the process of machining, the free abrasive are added into wire and mechanical parts as the third party to cut. This technique is successfully used in processing of silicon and silicon carbide. In order to further shorten processing time, as well as on other hard material and ceramic, diamond abrasive will be fixed to a metal wire in a certain way, which compose a fixed diamond wires saw. As shown in figure, cutting lines with high-speed reciprocating motion drive the slurry to the cutting area, which makes the abrasive particles (SiC particles) in the mortar and the surface of silicon rod make high speed grinding. Because the abrasive particles have very sharp edges and its hardness is greater than the hardness of silicon rods, the contact area of silicon rod and diamond wires saw are grinded out gradually by mortar. Thus the effect of cutting will be achieved, and meanwhile the mortar also can take away a lot of hot produced in the grinding. In the process of cognition of diamond wire saw cutting mechanism, many researchers believe that the micro cutting movement of diamond grits is a scroll and embedded process. They put forward the "scroll - embedded" model. ChinShine reachers put forward diamond wire sawing force drives on the abrasive grits rolling along the cutting surface, squeezing and embedded abrasive cutting surface at the same time. Consequently there is a flake piece of chip and surface crack, forming the big cutting function. ChinShine researchers pointed out that in "scroll - embedded" model, the particle movement also includes scratches, in addition to the rolling and embedded. All three work together for cutting. Bhagavat and some researchers considered the effect of pulping in this model and believe that the diamond saw wire leads free abrasive cutting silicon ingot of small area, and the movement of diamond wires saw and grinding pulping form a elastic fluid dynamic environment. They can use the finite element method (fem) to analysis the elastic fluid dynamics model of diamond wires saw and silicon ingot to get the function of diamond wire walking speed, viscosity of grinder and cutting conditions. Then they draw the conclusion: pulping film thickness is greater than the average particle size, is the flow of the abrasive cutting.
