CYLINDRICAL WHEELS Cylindrical wheels are used most often when the part is held between centers and in chucks. There are two methods of cylindrical grinding, traverse and plunge: • Traverse grinding – wheel moves across the part. • Plunge grinding – wheel is thrust or plunged into the part. TYPICAL INDUSTRIES • Automotive • Aerospace
Cylindrical grinding. JUNKER cylindrical grinding machines enable extremely efficient grinding processes with a high degree of process reliability, the ultimate in workpiece quality and a optimum costtoperformance ratio across a wide range of industries.
Conventional External Cylindrical Plunge Grinding. The conventional external cylindrical plunge grinding process is still stateoftheart in many production environments. The fundamental advantage of process experience is, at the same time, a considerable drawback when it comes to innovation.
Cylindrical grinding can be carried out by traversing the length of the surface, or plunge cutting can be used for narrower features. For centre grinding the work piece is either held between 2 centres and driven by a drive dog, or one end is driven by a chuck and the other end is located by the centre.
Kinds Of Centerless Grinding. Like centertype cylindrical grinding, which can use plunge or traverse motions to grind a workpiece, centerless grinding too has different ways to get the job done. The two most common centerless grinding techniques arie infeed and thrufeed. Setting up for infeed is the less complicated of the two.
The plunge grinding method is used when components have a headed section that does not require grinding. The shaft can be ground without the need to touch the head. Multiple diameters can also be ground simultaneously. Plunge grinding is often used as an alternative to the more expensive cylindrical grinding method.
