The rotation direction of the roller is divided into two types: forward dressing and reverse dressing. Most of them use the forward dressing method (the direction of the linear velocity of the contact point of the grinding wheel is the same); the reverse dressing will be affects the life of the diamond roller.

Flame spraying is one of the oldest forms of thermal spray. Typically using oxygen and acetylene, these thermal spray systems melt wire or powder in the combustion stream and apply it to the part. These coatings are great for restoration of old parts. Flame spraying systems can spray I.D. and O.D. components and can be readily brought to a customer site for repairs if needed.

The surface roughness Ra< 0.01µm and the flatness plane is< 3µm/1000mm after the workpiece grinding.

Gear machining is an extremely complicated process. The gear machining cycle includes turning → hobbing → gear shaping → shaving → hard turning → grinding → honing → drilling → inner grinding → Welding → Measurement, it is particularly important to configure a suitable clamping system for this process. Next, we will introduce the gear clamping system in various processes.

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.
