Molding and Hardening of Resin Grinding Wheel

resin grinding wheel is one of the very common. Resin grinding wheel high strength, has a certain degree of elasticity, widely used in aluminum alloy doors and windows processing, construction industry, shipbuilding, mechanical processing, automobile maintenance, electronic medical industry, metallurgy, DIY & woodworking and other industries. The molded resin grinding wheel body has a certain hardness, strength and heat resistance after heating treatment. This process is called hardening. Hardening is one of the key processes that determine the performance and quality of the resin grinding wheel.
resin grinding wheel body hardening generally using hot air as the heat transfer medium, commonly used as a heating energy, by the electric heating element to heat the air after transfer to the body to heat hardening, often use the electric heating air hardening equipment for chamber type hardening furnace.
The original chamber-type hardening temperature control system uses a relay control system. This system uses hard-wired mode, although the flexibility is poor, the mechanical contact working frequency is low, easy to damage in the case of continuous operation and other shortcomings, but the system load on the voltage waveform is not distorted, still a complete sine wave.
At present, most of the hardened temperature control systems use thyristors or power electronic solid-state relay control systems. These systems have the advantages of high sensitivity, fast switching speed and long life, but the voltage waveform on the system load will change more or less, and there are harmonic components.
From the perspective of engineering practice, it is necessary to design and develop a new type of control system specifically for hardening, to minimize the impact of power electronic devices on the voltage waveform, while retaining its convenient control characteristics.
