Cylindrical Grinding is a metalworking process that uses a rotary grinder to form a finished surface on the inside or outside of a cylindrical workpiece. Cylindrical grinding is often used on workpieces that are too long and/or heavy to be turned, but it can also be used for accurate and precise surface finishes on cylindrical components, such as shafts, axles, and gears.
The cylindrical grinding process begins with the grinding wheel being fed into the workpiece, and then rotating at high speeds. As it rotates, the wheel cuts off portions of material from the workpiece’s surface, creating a profile on its surface. The cylindrical grinding process can be performed wet or dry, depending on the type of material being ground and desired results.
What are three types of cylindrical grinders?
A cylindrical grinder is a machine tool that is used to grind, cut, shape or finish metal. They are classified in three types: center type cylindrical grinding; chuck type cylindrical grinding; internal cylindrical grinding.
1. Center type cylindrical grinding: is a process for grinding the end faces of a cylindrical workpiece. Center type cylindrical grinding is one of the most common operations in precision machining. It is used to grind and polish the ends of cylinders, tubes, and other round parts to a desired diameter or surface finish.
2. Chuck type cylindrical grinding: is a type of cylindrical grinding that is done by using a chuck. The chuck type cylindrical grinding process is used to grind the external surface of the workpiece. The workpiece is clamped in a chuck and rotated with the spindle. The abrasive wheel turns at an angle to the axis of rotation for this process. There are mainly two types of cylindrical grinding. They are side chucking and end chucking. Side chucking: It is the most common type of cylindrical grinding, which can be used for roughing, finishing and semi-finishing operations. End chucking: It is a less common type of cylindrical grinding and it is mainly used for finishing operations.
3. Internal cylindrical grinding: is a surface grinding process that produces a cylindrical surface with a uniform cross-section. Internal cylindrical grinding is used for the production of parts with a cylindrical shape, such as pipes and tubes. This process produces an axial plane of contact between the workpiece and the grinding wheel, which offers advantages in some applications, such as when producing pipes for high-pressure fluid transport systems.
What type of work can be done in cylindrical grinding?
There are many different types of work that can be done in cylindrical grinding. The most common works can be done in two ways: internal cylindrical grinding and external cylindrical grinding.
1. Internal Cylindrical Grinding: Internal cylindrical grinding is used to produce a smooth surface on a workpiece. It can also be used to reduce the diameter, taper or chamfer an internal thread, or for general deburring and finishing.
2. External Cylindrical Grinding: External cylindrical grinding is used to produce a flat surface on a cylinder. It can also be used to reduce the diameter and taper an external thread, or for general deburring and finishing.
Internal cylindrical grinding is used to machine the inside of a cylindrical object and machining internal surfaces on cylinders . External cylindrical grinding is used to machine the outside of a cylindrical object and machining external surfaces on cylinders.
