Centerless Grinding – Aerospace Centerless Grinding Wheel

Name: Centerless Grinding - Feed/Regulating Wheels
Brand: CUMI Abrasives
SKU: CGW-FRW-001
Author: CUMI Abrasive Team

An application which presents the most daunting challenges to any abrasive manufacturer. The range of requirements and priorities of this application varies from product to product which calls for an equally wide range of offerings to suit the same. Since in most of the Centerless applications, more than one wheel is mounted on the spindle, extremely tight tolerances need to be maintained in the geometry and densities of the wheels to ensure uniform wear patterns even if each wheel in the set is different. CUMI has the expertise, when it comes to Centerless applications thanks to the advanced manufacturing process, premium Abrasive grains and specially designed Vitrified, Resin and Rubber bond systems to suit the application needs. Customized solutions are provided for every application and specific requirement. Be it through-feed, end-feed or in-feed, CUMI wheels ensure that components are finished to stringent quality requirements.

Product Description

Centerless grinding wheels – Description

Centerless grinding wheels are precision-engineered abrasive tools designed for high-accuracy cylindrical grinding on centreless machines, particularly in demanding aerospace manufacturing environments. Unlike conventional grinding, centerless grinding supports the workpiece between a grinding wheel and a regulating wheel, eliminating the need for centers or chucks and enabling continuous, high-throughput operations with exceptional dimensional control.

In aerospace applications, a centerless grinding wheel plays a critical role in producing components that require tight tolerances, consistent roundness, and superior surface finish. These wheels are commonly used for grinding shafts, pins, rods, and other cylindrical parts manufactured from high-strength alloys, titanium, and other aerospace-grade materials. The controlled abrasive action ensures stable grinding performance while minimizing thermal damage and maintaining component integrity.

Designed to operate across through-feed, end-feed, and in-feed processes, centreless wheels for aerospace are built to deliver uniform wear, predictable performance, and long service life on Centreless Machines. Their optimized grain and bond systems support reduced dressing frequency and improved process stability, making them suitable for both high-volume production and precision batch grinding. For aerospace manufacturers focused on repeatability, quality compliance, and productivity, centerless grinding wheels provide a reliable and proven solution.
