How To Produce The Abrasive cut-off Wheel

The manufacturing process of abrasive cut-off wheel can be roughly divided into 7 parts: batching and mixing, pressing molding, loading after drying, sintering, unloading processing, inspection and packaging. It can be said that it is a product with a long production cycle, and because the abrasive is easily consumed in the air, its performance will be weakened at any time. Generally, the consumption speed is faster in the finished product out of the warehouse within a week, and then it will be slightly slowed down. Therefore, most manufacturers in the customer order after the production of good products, it is best to send as soon as possible to the customer, so as not to meet the original cutting performance requirements.

     

The abrasive wheel forming process is to mix the abrasive and binder into the mold to distribute evenly, and then run the equipment to press down. When the pressure reaches a predetermined value, the pressure is kept for a period of time, and then the pressure is relieved and returned, and the finished product is pushed out of the cylinder. Next, the pressed abrasive cutting disc needs to be dried, which can be divided into natural drying in natural environment, artificial drying in artificial heating mode, and continuous drying with both of them, and then it is loaded in series to be sintered in drawer furnace or tunnel furnace. The time of different sintering furnaces is different, and the strength of cut-off wheel will be different. In this process, ceramic is called sintering; Resin abrasive cut-off wheel is called hardening; Rubber    is called vulcanization. The whole process is completed by the temperature change of temperature, constant temperature and cooling. After that, it is necessary to unload the string, and then it is necessary to process and check. The purpose of this process is to check some abrasive cut-off wheels that are not successfully pressed or not completely sintered, and carry out backfiring or discarding. Of course, there will also be some tests, such as the weight, speed and cutting performance of the them, called the rotary test. There will be corresponding equipment and allowable error range for data reference, so as to verify whether the product is qualified. Some manufacturers, may also be more than a seal process, in the appearance of the product, size, hardness, balance, strength to carry out strict inspection, so that it meets the requirements of the standard, and qualified products stamped with the standard requirements of the seal, and according to the batch printing product certificate.

 

Finally, it is the packaging of the abrasive cut-off wheel. The appearance shape and color of it are also inspected during the packaging of the finished product. Especially for that with blister packaging, air and breakage shall not be left in the blister, and it must be completely fitted. The color and size of the trademark shall be checked again. If there are no problems, the final production will be over. And, of course, the abrasive cutting disc production process working procedure will be different in different market, with different size, different abrasive industry and application different abrasive cut-off wheel production machines, and each production process name will be different, referred to in the above general production process is the common size of resin abrasive cut-off wheel, different sizes should be analyzed according to the actual situation and abrasive production process.
