Tungsten carbide tips automatic brazing machine for 280-500 saw blade
This machine is automatic brazing machine for brazing tungsten carbide tips with saw blades by high frequency brazing, it mainly suitable for welding TCT saw blades of dia 280-500mm in paper, wood and aluminum processing industry.
Features
- Automatic feed carbide segments, rotate saw blades, flushing flux and centering on the saw blade in the brazing process.
- Centering accuracy is about plus or minus 0.03mm, brazing firmly and quality is stable.
- New design feeding system of rotating disk with vibration.
- Control the brazing by setting time and temperature, automatic adjust tempering function on high accuracy to apply various demand of brazing.
Process
The process of electric induction brazing is shown and explained while watching the machine in action that automates parts of this process, with the aid of manually pushing buttons at the right time and manually adding necessary materials for the brazing of the diamond blade to be completed. Diamond blades are used for cutting materials that are especially tough to cut through, such as stone, concrete or asphalt. Segments eventually wear out with heavy use and then need to be replaced to make the blade effective again for cutting through tough materials. This video shows the process of soldering new diamond segments around the outside edge of a large blade.
After stripping it, will clean it with an air sander, it is important that the surface is clean when soldering so all will bond to it, now it will go through the heat cycle, 24 seconds, segment gets red, not it is going through the cooling cycle, the indexer, clamp the blade, then it will go through the cycle again, add flux, solder won’t stick without the flux, placing segment, heating both sides at the same time, put less heat on the blade, good consistency for the segment, minimal segment loss.
