Get Introduced to Centerless Grinding and its Various Benefits

Posted On: April 15, 2019

In the manufacturing industry, various machining processes are employed to produce perfect workpiece. Some of these processes have been around for a while, and are still popular due to continuous advancements. Centerless grinding is one such process, which has gained immense popularity in recent years. It is one of those grinding techniques, which is being increasingly employed for short-term manufacturing. What this process is all about, and its various types? Why is this process popular among manufacturers? Are you intrigued to know? Well, you have to read this post to find answers. It also helps you understand the process better.

A Peek into the Centerless Grinding Process

In this grinding, the workpiece is placed between two wheels, and a work holding platform. Though the wheels are rotating in the same direction, they have different speeds. Among the two wheels, one is the grinding wheel, and the other is the regulating wheel. The grinding wheel rotates on its own axis and produces a force, which is directed against the platform holding the workpiece. This wheel performs grinding at higher tangential speed. However, the regulating wheel features a rubber-bonded abrasive which holds the workpiece. This wheel applies lateral pressure to the workpiece. The rate of material removal depends on the relative speed of these two wheels.

4 Top Reasons That Make Centerless Grinding a Preferred Choice among Manufacturers

• Saves Time:

  Today, manufacturers are keen to improve their time-to-market capabilities. Adopting time-saving processes is a big step towards it. This is where centerless grinding can make a difference. The centerless grinders are fully-automated, which means work pieces are loaded and machined automatically. This is a great advantage in comparison to traditional OD grinders. Smaller work pieces can be loaded in bulk quantities, and they will ground by means of hopper feeder attachments, gravity chute, and magazine. Minimized manual efforts, and maximized productivity makes it one of the most beneficial processes, for all manufacturers aiming high ROI.

• Enables Tighter Tolerances:

  As discussed before, the workpiece is tightly held in its place by the regulating wheel, grinding wheel, as well as the work blade. This helps achieve tighter tolerances. Additionally, the work piece is supported under the cut, as well during the entire length of the grinding cut. This means, there is no end pressure or axial thrust imposed on the work piece, which enables easy grinding of longer, as well as brittle work pieces.

• Immense Cost Savings:

  Centerless grinders require fewer or almost no maintenance, once set up. As the grinding process is mature, thus there is no need for adjustments, which helps save maintenance costs. In addition to this, the process enables a long wheel life by eliminating the centering related errors.

• A Choice between In-feed and Through-feed:

  This technique is ideal for symmetrical and asymmetrical work pieces. A manufacturer can easily select from either of the two methods – through-feed and in-feed grinding. The through-feed technique is ideal for parts with consistent thickness and roundness across its length, whereas in-feed method is suited for grinding complex shaped, cylindrical parts.

All the above-mentioned reasons have contributed to the popularity of centerless grinding. Do you want to know the other benefits of this technique? If yes, you can contact a reliable industry expert like BDE Manufacturing Technologies.
