The Selection Guides of Cutting and Grinding Wheels

1. A high-quality cutting and grinding wheel basically features uniform internal structure, no crack and edge-dropping, and low noise.

2. The rotational speed, static imbalance value and the limit deviation of geometric size are important guarantee for China grind wheel operation safety.

3. In the process of material cutting and burr grinding, only to maximize the use characteristics of China grinding disc you can improve work efficiency, reduce consumption, and save production costs. How to maximize the use of China grinding disc? Only according to the workpiece to select the grinding wheel of corresponding material.

4. The choice of grind wheel grain size directly affects the workpiece surface finish and grinding efficiency, in general, grinding efficiency is high using coarse-grained wheel grinding, but the workpiece surface is roughness; with a fine-grained grinding wheel, the workpiece surface finish is better, but the grinding efficiency is correspondingly low, in short, with the premise of meeting the requirements of surface roughness, the operator should try to use coarse-grained wheel grinding to ensure a higher grinding efficiency.

5. Under normal circumstances, the higher the hardness of the workpiece, the softer the hardness of grind wheel should be. When the contact surface or grinding pressure between cutting and grinding wheel and workpiece is too large, it should soften the hardness of the grinding wheel; when grinding the workpiece of poor thermal conductivity, in order to avoid burns, annealing, the hardness of grinding wheel should be soft; When adjusting the grinding, to choose the grind wheel having low hardness.
