Wheel Dresser

(1) Diamond pen dressing grinding wheel: According to the size of diamond particles and their distribution in the pen, diamond pens can be divided into several types, such as chain and powder. The alloy with strong bonding force is used as the bonding agent, so the diamond grinding wheel particles are not easy to fall off during use, so there is no need to repair the grinding process.

(2) Grinding wheel dressing by rolling method: Diamond grinding wheel dressing by rolling method. Grinding wheel drives the rolling wheel at the speed of 1~2m/s by reducing the speed

Made of, carbide or abrasive) rotary. The pressure of rolling wheel applied to grinding wheel is about 3~5MPa, grinding the surface of diamond grinding wheel

Make the abrasive particles fall off. The grinding wheel dressing by rolling method has better cutting performance and lower cost, but the surface roughness of the grinding part is rougher and rolling

Damage, short life, easy loss of precision. Therefore, this dressing method is mainly used for forming grinding with small batch size and low precision.

Green silicon carbide or ceramic white corundum is used for dressing. Dressing ring is the first choice for dressing diamond grinding wheel or CBN grinding wheel. It is sharp in dressing, not easy to remove sand and has high dressing efficiency.
