What is Centerless Grinding?

At Amerascrew, our centerless grinding services in Mansfield, Ohio include an abrasive cutting process to remove material from a workpiece. But what is centerless grinding? Centerless Grinding is the cylindrical workpiece (to be ground) that need not have centers drilled on its face. The centerless grinding machine eliminates the need for center holes, drivers, and other holding devices or fixtures to hold the workpiece.

Centerless Grinding is commonly used for:

  • Precision Size
  • Fine Finishes
  • Resizing
  • Truing Up After Heat Treating

The most common types of materials used are:

  • Steel
  • Aluminum
  • Brass
  • Bronze

Amerascew has two Cincinnati centerless grinders with a 4” capacity and an Automatic cycle Royal Master centerless grinder. This gives us a wide-ranging capacity. Amerascrew has the resources to take more material off fast with the large machines and the capability and repeatability of holding fine finishes on small parts.

Ameracrew also provides some diversity through different grit-wheels:

  • Through Feeding
  • Plunge Grinding.

In through-feed grinding, you have to position the regulating wheel at a nominal inclination to the grinding wheel axis and the workpiece rotates and moves forward during grinding.

The plunge grinding process uses a three-point positioning method. This allows us to grind even the smallest diameters with the grind length entirely supported.

Unfortunately, high volume, high-quality grinding is quickly becoming a lost art., but at Amerascrew in Mansfield, Ohio, we have the skills and knowledgeable employee base capable of getting the job done right for you! We are happy to chat with you about your next centerless-gridning need!
