In my opinion, under the condition that the spindle speed remains the same, the diameter of the grinding wheel is large, which is equivalent to the linear speed of the grinding wheel, and the roughness of the grinding workpiece is small for the grinding wheel of the same specification, that is, the finish will be high. In this way, the abrasive grains of the grinding wheel will appear to be passivated and have not fallen off.

So, if you feel that the diameter of the grinding wheel increases, it will produce wavy chatter.

In the same way, if the diameter of the grinding wheel is small, the grinding wheel will feel soft, and the grinding wheel abrasive particles will fall off quickly, and they will fall off before passivation, and new abrasive grains will appear for cutting, and at this time, there will be no wavy chatter.

1. Forging: If overburning, overheating, internal cracking into network carbide and so on are generated during the forging process, the toughness and strength of the ferrule will be reduced. Therefore, it is necessary to strictly control the processing temperature, circulating heating and post-forging heat dissipation conditions (such as spray cooling), especially after the final forging of the larger varieties of ferrules, the temperature is above 700, and it is not allowed to be stacked.

2. Heat treatment: close monitoring of heat treatment equipment is an important task in the workshop. Monitor the reliability of your equipment. Important temperature control instruments such as instruments and thermocouples must be closely monitored to ensure that the measurement data is accurate and reliable; If the error exceeds the standard, it should be replaced in time, and it is strictly forbidden to run with illness.

3. Monitoring of grinding process. The imported bearing ring of the finished product is not allowed to have grinding burns and grinding cracks, especially on the mating surface of the inner ring to change the taper. If the ferrule is pickled, it should be fully inspected, and the burned product should be removed, and the severe burns that cannot be repaired or repaired unqualified should be scrapped, and the ferrule with grinding burns is not allowed to enter the assembly process.

4. Identification management, after the steel is stored and before the ferrule grinding, each process must be strictly managed, and the two different materials and products of GCR15 and GCR15SIMN must be strictly distinguished.

1. Raw material selection, tetrafluoropolyetheretherketone and other materials can be used 2, and the mixture is carried out after formula proportioning.

3. The mixed material is molded into a tube or bar.

4. High temperature sintering.

5. Cooling and forming.

6. Then processed by CNC machining center.

7. Damanson sealing experts can provide technical information.
