Both round bar and precision ground bar have their place in manufacturing, and the choice between these two types of bar depends on the requisite level of precision required by the manufacturer. For applications that require higher levels of precision, it is important to team up with an experienced grinding partner, like Boston Centerless. We are an integrated product service provider that not only delivers outstanding precision ground bar via our AccuRod® and GrindAll grinding services, but also offers a wide range of value-added services such as heat treating, straightening, laser marking, and material testing and validation. When combined with our precision grinding operations, these steps can reduce costs, decrease time to market, increase productivity, enhance quality, and improve responsiveness for our customers.
What is Precision Centerless Grinding?
At Boston Centerless, we utilize centerless grinding to supply a variety of industries with precision bar materials. These industries rely on our high precision bar materials to optimize the performance of their products. Companies looking for the best quality bar depend on Boston Centerless.
Centerless grinding is an efficient machining process that is suitable for stock removal for bar materials. The workpiece is situated between two wheels that rotate to remove stock material via abrasive cutting. There are 3 primary methods for centerless grinding: thru-feed, in-feed, and end-feed. The main distinction between these techniques is the method used to feed the workpiece through the grinder. Boston Centerless primarily uses the thru-feed method but can also do in-feed grinding. In addition to unparalleled precision, centerless grinding delivers faster turnaround times compared to other grinding techniques.
As a recognized industry leader in Lean Manufacturing, our approach to precision grinding often distinguishes us from other providers. At Boston Centerless, our operators are experts in their craft, leveraging the know-how they have developed over many years. Our approach permeates our culture, including our operator training programs, and enables our team to deliver an unparalleled level of precision and quality that our customers rely on. At Boston Centerless, we set the standard and are a role model for U.S. manufacturing.
