Need machining solutions for your round bars? This can all be summed up in one operation called precision centerless grinding.
If your operation requires the challenge of machining and grinding round parts and components with long length and complex shapes and sizes, precision centerless grinding at Advance Grinding must be the first thing on the list. The reason behind this is that centerless grinding covers multiple tasks such as polishing, roughing, cleaning, and finishing – which are all significant to the greater process.
Centerless Grinding Advantages
Centerless grinding is a type of OD (outside diameter) grinding that enhances the materials’ all-around surface polish, straightness and diameter tolerance. Unlike other traditional grinding operations, the process doesn’t require much in the way of supporting tools but the work blade itself, which is held between the grinding wheel and the regulating wheel, must be properly adjusted for a proper hold.
Centerless grinding for long round bars
Centerless grinding is consistently used for grinding long round bars that are prepared in a single pass. Long round bars, tubes, and even pistons are ground using this process to achieve the required diameter tolerance, roundness, and surface polish. Through-feed centerless grinding is best suited for this process.
Centerless grinding for complex parts
Having complex parts is never a problem when it comes to precision centerless grinding operation. The abrasive grains on the wheel and the controlled support enable it to grind the smallest part diameter and even out-of-round materials.
This kind of cylindrical surface grinding is a very thorough process that makes it possible to achieve accurate diameter tolerance, perfect straightness, and precision roundness. In the production of camshafts, crankshafts, and gear shafts, the in-feed centerless grinding is preferred.
Making round bars rounder
Precision centerless grinding removes metal and grinds the surface of a round bar in a rounding action. The application of thousands of abrasive grains on the grinding wheel allows for the perfect grinding process. These grains take a bite to the workpiece to remove the unnecessary parts.
The continuous rounding motion achieves precise roundness and diameter tolerance. The process wears and loses some of the abrasive grains from the wheel, so the operator must constantly keep the wheel dressed with new abrasive grains in order to keep consistent shape and surface conditions for precision centerless grinding.
The three-part position
It takes a proper three-part positioning of the grinding wheel, regulating wheel, and the work blade that supports the bar(workpiece) to perform thorough and accurate grinding. The method to achieving perfect results and production of centerless grinding lies in ensuring the consistency of the gap between the wheels and the placement of the work blade on the centerline to determine the desired surface finish and diameter perfection of the bar.
One good thing about this grinding method is that the setup is much less daunting and complicated than other machining operations. In addition, the application of automated centerless grinding products, like that in CNC and servo motor technology makes the work even easier and requires less time-consuming exercises – which leads to the production of bars and parts in fast lead times!
