Choosing the suitable grinding disc for your needs needs to consider a number of factors, the following are detailed for you:
** First, consider processing materials **
1.If the processing is high hardness materials, such as stone, metal, etc., should choose diamond grinding disc or high hardness grinding wheel. For example, when polishing marble, diamond water grinding is usually a better choice because of its excellent grinding force and wear resistance.
2. For softer materials, such as wood, plastic, etc., you can choose emery cloth grinding or fiber reinforced resin grinding, which can ensure the processing effect while reducing excessive wear on the material.
Two, clear processing purpose **
1. If it is coarse grinding, it is necessary to select a grinding disc with large particle size and high grinding efficiency. For example, when removing rust and thicker oxide layers on the metal surface, coarse-grained Angle grinding pieces can be selected.
2. If it is fine grinding or polishing, it is necessary to choose a smaller particle size and a more delicate surface. For example, for the surface polishing of metal parts, grinding pieces with a particle size of more than 1000 mesh may be selected.
** Three, pay attention to the size and shape of the grinding disc **
1. According to the space size of the tool used and the processing part, choose the appropriate size of the grinding disc. For example, working in narrow Spaces may require the selection of a smaller grinding disc.
2. Different shapes of grinding plates are suitable for different processing scenarios. For example, surface processing is suitable for using round grinding, while for corner and edge processing, triangular or shaped grinding may be required.
** Four, understand the type of binder for the grinding plate **
1. The resin binder grinding disc has high elasticity and self-sharpness, which is suitable for the situation that good surface quality and accuracy need to be maintained in the grinding process.
2. Ceramic binder grinding plate has high hardness and wear resistance, suitable for efficient grinding and heavy duty processing.
** Five, consider the working conditions **
1. If the working environment temperature is high, the high temperature resistant grinding disc should be selected to prevent the performance decline or damage of the grinding disc at high temperature.
2. When working in a humid environment, it is necessary to choose a grinding disc with waterproof performance to avoid affecting the grinding effect and service life of the grinding disc due to water absorption.
** Six, brand and quality **
1. Choosing a well-known brand of grinding disc can usually guarantee a certain quality and performance. These brands tend to be more stringent in terms of production processes, raw material selection and quality control.
2. You can view the evaluation of other users and professional product evaluation to understand the actual performance of different brands.
In short, the choice of suitable for their needs needs to consider the above factors, and according to the specific processing tasks and working conditions to weigh and choose. For example, in a machine processing plant, workers need to rough grind and polish a batch of metal parts. For the rough grinding process, they chose a ceramic binder Angle grinding plate with larger particle size and higher hardness to quickly remove surface defects and residual; In the polishing process, the round grinding plate with fine particle size and resin binder is selected to obtain a smooth and bright surface effect.
