There are several specialized types of grinding used today. Each is designed to provide specific shaping and forming of the workpiece through different systems and methods.
Cylindrical grinding can be used for both inside and outside grinding requirements. This is a machine which has been in use since the Industrial Revolution and is based on the same functioning and operation as the very ancient lathe. Of course, today’s OD grinding is very precise with both manual and CNC (computer numerical control) equipment.
The Method
Each workpiece is held in place by two centers, which are at the ends of the workpiece. The centers are designed to hold the workpiece and creating a rotation for the workpiece.
At the same time, there is a grinding wheel positioned along the workpiece anywhere between the two centers or endpoints. The grinding wheel is rotated in the opposite direction to the workpiece by the equipment.
The grinding wheel for OD grinding follows a very precise path up and down the workpiece, with both turning at the same speed but in opposite directions. The result is a smooth, even grinding process which can be very effectively controlled by the operator or the CNC system.
The use of this type of grinding can produce uniform shapes, such as shafts and rollers, or it can also be used to create cylinders and cores. It is also an effective way to make more complex shapes such as taper grinds, mandrels, and contoured exterior shapes.
Different Considerations
Hiring a service for any type of outside diameter grinding means understanding specifically what is required with regards to tolerances. Additionally, the length and diameter of the workpiece will also be a factor as this equipment will have a maximum size for both.
Always consider other grinding services required when choosing a service. This will allow one shop to handle all the grinding requirements, streamlining the process for the OEM.
