The role of cutting blades for angle grinders is self-evident, just like the role of teeth for humans, once the cutting blades break during operation, it is easy to cause serious injuries to people, so it is very important to manufacture high-quality and qualified cutting pieces.
One: batching link
Resin, abrasives (such as brown corundum), cryolite, binder and other raw materials, according to the formula requirements, a certain proportion of raw materials through the funnel into the raw material barrel.
The mixed raw materials are fully mixed and stirred, and the mixed raw materials must be repeatedly filtered and screened to remove impurities and ensure that the raw material particles are the same size.
Two: Forming link
In order to solidify the raw materials, the quality of the matrix is also extremely critical, first of all, the grid-like bakelite board is used as the matrix to support the abrasive, so the bakelite board matrix needs to be placed at the bottom of the mold when manufacturing the cutting piece.
Then the abrasive is filled on the top and covered on the glass fiber mesh plate matrix, and after the filler process is completed, the abrasive mixed with various raw materials is pressed and formed by the machine cold pressing method.
The pressed and formed cutting blade is pressed up by a machine.
Three: hardening link
The pressed cutting blade is put into a kiln and dried and hardened at high temperature, or by drying it in a natural environment, or by continuous drying method that combines natural and high temperature.
Four: test packaging
Sampling of cutting discs for strict inspection of appearance, size, hardness, etc.
The maximum speed of the cutting blade will also be sampled in batches, which is very important (if the maximum speed of the machine exceeds the maximum speed of the cutting blade, then it is very likely that the cutting blade will burst during use, and the consequences are serious). ）
Through the manipulator, each piece of the cutting blade is put on the rotating disk, and the glue is dripped on it so that the front and back sides are pasted with the packaging trademark, and the cutting blade can be sold at the factory.
