Centerless Grinding: Breakthrough in Automotive Applications

automotive applications

Centerless grinding made such a breakthrough in the automotive industry since it can bring up all desired precision and tight tolerance to components.

As we all know centerless grinding really makes a big breakthrough in the machining industry. Being recognized as highly rated machining operation that gains almost perfect surface polish, tight diametrical tolerance, and high precision, centerless grinding is edging itself to get highest ranging demands from metal workers and manufacturers.

Purpose-built centreless grinding machines are used upon the operation. Such machines are composed of a grinding wheel, regulating wheel, and some supporting tools for holding workpiece. With the implementation of proper positioning with these tools, the required finish is a sure catch at each end phase of the operation.

Centerless Grinding for camshafts and crankshafts

Centerless grinding is used mainly in the manufacturing of automobile parts and engines and components such as camshafts, crankshafts, needle rollers, input shafts, and injector plungers.Such components have dire need of precision and tight tolerance to function perfectly in each of its designated applications.

The highly increasing demand for precision components gives the operation itself a big role in keeping the wheels turning in the machining industry.

But centerless grinding is not just be applied in automotive applications. It is also highly sought among the large areas that require high precision among raw materials to be used such as the aerospace structure for turbine engines, tubes for both industrial and medical purposes, etc.

Accuracy Achieved

Accurate polish and finish is achieved through the abrasive material removal done by the grinding operation. This operation has no “centers” to be exact. In other words, centreless grinding does not include spindles or fixtures to hold the workpiece while being ground. It’s just a matter of the positioning placed between the grinding wheel, regulating wheel, and the workblade.

Centerless grinding has been eminently used in achieving custom sizes. To achieve ranging sizes, form, and finish demands, centreless grinding is categorized into two primary forms:

Through-feed/ Thrufeed grinding

If the challenge is to grind long round bars, then through feed is best applied in the process. This course done through letting workpiece be fed to the machine and is pulled past by the regulating wheel and flown out of the opposite side. Through-feed/ thrufeed is highly efficient for separate feed mechanism is not required; but, it can only be applied in workpieces with simple cylindrical shape such as pistons, tubes, pistons pins, and bars.

In-feed/ Plunge grinding

If the requirement is for the relatively complex parts and shapes to be ground to their highly precise finish, in-feed/ plunge grinding is used. Gear shafts, crankshafts, and camshafts are really complex automotive components that need the implementation of in-feed grinding to achieve the desired ground and finish. The workpiece is loaded into the machine, allowing the regulating wheel to move into place. The complexity of the component shape requires grinding them accurately to prevent the workpiece to be fed axially through the machine.
