Choose cutting wheels, everyone seems to like explosive models. However, in industrial processing, the construction situation you encounter is different, the material of the workpiece is different, and the material type of the super thin double mesh cutting disc used is also different.
A good super thin double mesh cutting disc will allow you to get twice the result with half the effort when processing workpieces. A good super thin double mesh cutting disc must not lack these three things.
The grinding rate of the first product, what is the grinding rate of the product?
The grinding ratio refers to the cutting efficiency of the grinding wheel. The less the loss of the grinding wheel (including the reconditioning amount), the more the workpiece is cut, the higher the grinding ratio, and the better the performance of the grinding wheel. The calculation method is: grinding wheel loss volume/workpiece removal volume. As for the standard data of grinding ratio, the loss rate is also different due to the different types of grinding wheel binders (ceramic, resin, rubber, bitter diamond, etc.). A more accurate grinding ratio can be obtained by adding parameters such as abrasive grade, grain size, bonding degree, softness and hardness, tissue density, and various bonding agents.
Basic Concept:
The ratio of the material removal amount of the workpiece to the wear amount of the grinding wheel is called the grinding ratio.
Grinding Specific Energy:
Grinding specific energy Es refers to the energy consumed per unit time to remove a unit volume of workpiece material. It can usually be expressed as: Es=Pmvwapb where: Pm is energy consumption
Grinding Ratio:
Grinding ratio G=Vwc/Vsc
In the formula: Vwc - the volume of the workpiece to be ground;
Vsc – loss volume of the grinding wheel.
Grinding ratio is an important and commonly used indicator of the economical use of grinding wheels. The grinding ratio is greater than that of Yu, which means that the grinding wheel of the wear unit physical examination or quality can grind more metal, and the use of the grinding wheel is more economical.
Since the grinding wheel is composed of three volumes such as abrasive bond and pores, the volume Vsc of the worn grinding wheel also includes these three volumes. Sometimes the concept of wear ratio Φ is also used to express the economy of the grinding wheel in use.
Wear ratio Φ=Vsc/Vwc
It can be seen from the above formula that the wear ratio is actually the reciprocal of the grinding ratio. The grinding ratio can indicate the grindability of the material, while the wear ratio mainly indicates the wear resistance of the grinding wheel.
The second point is to look at product characteristics. It is also very important to choose products with such characteristics in what kind of environment.
The dressing of superabrasive grinding wheels is different from that of ordinary grinding wheels. The dressing process is divided into two stages: shaping and sharpening. The shaping stage refers to making the working surface of the grinding wheel have the required geometric accuracy of the shape and surface. The sharpening stage refers to the removal of excess bonding agent around the superhard abrasive grains on the working surface of the grinding wheel by means of sharpening, so that the abrasive grains are exposed to an ideal height, so that the working surface of the grinding wheel has good grinding performance. For a long time, many scholars have done a lot of research work on the dressing of superabrasive grinding wheels, and developed many effective dressing methods, mainly including mechanical dressing, electric machining dressing and other dressing methods. Mechanical methods mainly include turning method, grinding method, rolling trimming method, diamond roller trimming method; electrical processing methods mainly include electrolytic trimming method and electric spark trimming method; other trimming methods include laser trimming method, ultrasonic trimming method, etc.
