    The Tips of Re-tipping Core Drill Bits

    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...

Test each batch of powder provided by the famous manufacturer, and use them only after meeting the strict requirements. 2. Mix powders of different proportions (iron powder, cobalt powder, nickel powder, copper powder...) evenly, granulate them into small particles. 3. Put the powder and diamonds into the automatic cold press machine. Cold press the powder into different diamond segment shapes according to the mold. 4. Fully automatic sintering machine hot-press sintered segments. 5. We weld our diamond segments to the steel core to make complete saw blades, laser weld diamond blades from diameter 115 mm to 2000 mm. Pay attention to the following items during laser welding. Select the focal length to ensure that the laser energy is focused on welding. Adjust welding power and speed, both must match each other. 6. The diamond saw blade is edged, and the sides and edges of the saw blade need to be edged. 7. The post-processing of the saw blade steel core is mainly to polish and paint the steel core to prevent future rust. 8. According to customer requirements, mark the use direction according to the cutting edge direction, printing customer or ChinShine logo, printing waring information on blade. 9.

    The tips of diamond wire saw types and application - how to choose the right diamond wire for your concrete

    ChinShine offers a large selection of diamond wire saw rope developed for cutting a wide range of materials such as concrete, stone, reinforced concrete, underwater steel/pipe cutting in a variety of industries. There is basically no limit towards the depth or shape of a wire saw application. Our diamond wire saw rope function well with all wire saw types on the market. We offer various types of diamond wires that has different diamond densities and diamond bead diameters including vacuum brazed, double bead vacuum brazed and sintered options. Ideal to use vacuum brazed diamond wire saw rope; ChinShine professional-grade diamond wires with vacuum-brazed beads are engineered to cut through steel, alloy and heavily reinforced concrete. Vacuum brazed diamond wires have been developed for intense professional use in specialist applications such as heavy reinforced concrete cutting, underwater steel and pipe cutting, offshore/nuclear cuttings etc. It can be very aggressive cutting with high wire tension and it provides maximum cutting speed and improved wear resistance in heavy cutting. Vacuum brazed diamond wire Ideal to use sintered diamond wire saw rope; ChinShine premium sintered diamond wire saw rope is designed to provide a good balance of lifetime and cutting speed. General purpose sintered diamond wire is made for handling all types of concrete/reinforced concrete cutting applications such as demanding demolition, building, and renovation work, among others. It performs best with medium- to high-powered wire saws. ChinShine  sintered wires feature at least 40 beads per meter for the longest wire lifespan possible. It is ideal diamond wire for cutting concrete and stone. 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...
