Differences Between Thru-Feed And In-Feed Grinding

Depending on the industry you’re in, there are different types of grinding involved to ensure that your machinery works optimally. Most times, through-feed grinding is the ideal option for machines in the aerospace, automotive, defense and medical industries, but in-feed grinding is another method. At Sturdy Grinding in New Haven, MI, we use through-feed grinding techniques to provide high-quality products and increased productivity for your company. 

Thru-feed vs. In-Feed Grinding

Thru-feed grinding is a type of centerless grinding. During this process, the workpiece passes through the machine itself. It proves to be an effective option for single-size diameter parts anywhere from a small dowel pin to a 16” shaft. We’re able to automate our thru-feed operations via vibratory bowls, which allow for continuous feeding. This is perfect for our customers that have a high volume of output, and we can provide competitive pricing options.  

In-feed grinding is also a form of centerless grinding. This process, however, is optimized for workpieces with complex or abnormal shapes. The workpieces must be manually loaded into the grinding machine and then the regulator wheel is manually moved, as well. This process is optimal for complicated parts and wheel shapes. 

In short, thru-feed grinding is a simpler approach to your business’s grinding operations. It’s more affordable and more automatic, too!
