    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...

    Laser welding diamond saw blade manufacturing process

    Laser welded diamond saw blades are the main type of diamond saw blades for cutting reinforced concrete in the professional market, and people comes from large engineering construction field. ChinShine laser welded diamond saw blades have the advantages of good welding quality, small weld seam, narrow laser beam focus area, and precise effect on the interface between the steel core and the diamond segment. That is why the advantage of ChinShine laser welding diamond saw blade no deformation of the steel core after laser welding. ChinShine laser welded diamond saw blade production process: 1. 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. After all the diamond saw blades pass the inspection, they are put into boxes and wooden boxes. ChinShine – a professional manufacturer of diamond saw blades, if you want to know more about diamond saw blades, please feel free to tell us!

    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...

  • Hit by COVID wave, companies in China strain to keep operations running normally

    Hit by COVID wave, companies in China strain to keep operations running normally

    From e-commerce giant JD.com to cosmetics brand Sephora, companies in China are rushing to minimise the impact of surging COVID infections - doling out test kits, encouraging more work from home and, in some cases, procuring truckloads of medicine. After unprecedented protests against oft-draconian COVID curbs, the world's second-largest economy abruptly dropped its zero-tolerance COVID stance last week. The ensuing fierce spread of the virus has even forced certain businesses to shut their doors for the time being.  "More than half of our staff in the mall and the hotel are positive," said a senior executive at a firm that manages one of Beijing's largest retail complexes.  The executive, who declined to be identified, said the mall was still open with remaining staff splitting into two teams and only one team working a particular shift.  JD.com which is headquartered in Beijing and employs more than 540,000 people, has sent antigen test kits to its staff and is asking those who are sick to stay home, sources at the company told Reuters. At Sephora China, which has 321 stores across 89 cities on the mainland, each store is handling their staffing issues in accordance with their situation, said a spokesperson for the LVMH brand, adding that all staff testing positive will be given paid leave and can work from home if possible. 'DEEPLY FRUSTRATING' At another Beijing shopping centre, a gym belonging to the U.S. Powerhouse chain said on Tuesday it would be closed until Dec. 25 to disinfect the premises and to protect the safety of staff and members. "The spread of the virus is severe and there is a big risk of infection," said the gym. It had just reopened five days ago after having had to shut for more than two weeks due to district-wide COVID curbs. "It's deeply frustrating. Businesses are having to close due to staff being sick, even though they can legally be open," said Noah Fraser, Beijing-based managing director at the Canada-China Business Council. "Blame is starting to flow from companies' (foreign) headquarters to the team on the ground in China, with HQ asking ‘why can’t the China operations navigate these restrictions?’ All other markets have had to adjust and did so successfully," he said. Some factories and eateries are retaining COVID-19 curbs, including so-called closed-loop systems that isolate staff from the wider world, until they get a clearer picture of just how workplaces will be affected. At Volkswagen, which has seen its plants in China heavily disrupted by lockdowns this year, production is currently stable but the automaker has reduced office attendance and is asking staff to stay 1.5 metres apart whenever possible, a spokesperson said. Chinese electric vehicle maker Nio also said its production was normal, although it is bracing for infections. "We have sent trucks of medicines and equipment to the factory to be well prepared," Nio's president Qin Lihong told a media roundtable on Monday. National health of...
