Two enabling technologies — superabrasive wheels and high precision servo control — come together to provide a contour grinding process that resembles an OD turning operation. For many medium volume OD grinding applications, this method may be a means to consolidate several manufacturing steps into a single setup.

At present, sintering method is the main method in China. Compared with electroplating method, it has a longer life and more stable performance. On the contrary, electroplating method is more widely used than sintering method in foreign countries. The following figure shows the manufacturing methods and characteristics of sintered diamond rollers and electroplated diamond rollers.

Solution

1.  Adjust front and rear guides

2.  Replace coolant

3.  Round the edge of the grinding wheel so that the 20mm at the exit of the part will not be used for grinding

4.  Advance the center height of the parts properly

5.  Dressing the grinding wheel

6.  Properly reduce the amount of grinding and slow down the rate of modification

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.
