Dressing with rotating diamond tools has been found to be a reliable technique in series and performance grinding processes, especially those applications using vitrified bonded grinding wheels.

The precision machining process of grinding machines is often required to achieve very precise dimensional tolerances, geometric tolerances and extremely high surface quality. Most companies usually use their experience to meet these requirements. However, in the process of processing, people have an extremely urgent need for the measurement in the process, especially for the measurement and correction of errors in the process. Laser controlled measurement can significantly improve the stability and yield of the grinding process, which is a perfect, extensive and flexible solution for all kinds of parts.

There are two main combinations of diamond belts, one is electroplated bond diamond belt with monolayer diamond abrasive and very high sharpness, abrasive control force is better.

Another one is resin bond diamond belt, multi-layer diamond abrasive, with good self-sharpening, abrasive holding force is relatively weak, similar to a flexible grinding wheel.

The methodology of measurement and what is measured when calculating Ra and Rz are quite different. This is critical to understand if you will not be paid for your parts because the Ra you measured is not in fact the Rz surface profile that customer specified.

Super hard abrasive coatings are most commonly used on resin-bonded grinding wheels, while nickel and copper are the preferred coating materials. Coating thickness depends on coating material. Copper coating usually accounts for 50 % of the total weight of coated abrasive particles. Nickel coatings accounted for 30, 56 or 60 percent of the total weight of the coated grains. The 56 nickel coating has a stronger grain holding force (longer holding time), but it also generates more heat. Silver can also be used as a grainy coating for resin-bonded grinding wheels, which, despite its high cost, has the desired lubrication properties. The silver-coated super hard grinding wheel is mainly used to grind the spiral groove of the cemented carbide drill bit.

In recent years, everyone must be familiar with carbon fiber composite materials. Carbon fiber composite material is ubiquitous in all kinds of science fiction, racing movies. Such as the 350Z body in the Tokyo Drift “The Fast and the Furious Ⅲ”, the wings of the falcon in “Avengers”, the torso of the Baymax in “Big Hero 6” are all made of carbon fiber materials.

The dressing wheels are used for dressing diamond and CBN wheels. According to the different particle size, accuracy of the diamond and CBN grinding disc to choose the dressing wheel, making dressing easier and more time saving.

In addition to the standard, according to the American standard, the grit size ranges from 60 to 325, and the fine powder grade ranges from 400 to 14000. Please refer to the following table.

The camshaft on the automobile engine has multiple cams, and the rough grinding and fine grinding of the cam after quenching are the key processes that affect the quality of the cam. In general, imitative grinding is used, and the speed of the workpiece is limited, and the workpiece is prone to grinding burn cracks.
