Melling Industries offers in-house thrufeed grinding services ranging in capacity from ¼” to 3” O.D. and up to 12” in length. Our thrufeed grind equipment has the ability to produce a surface finish of 8 micro inches (Ra) and maintain a tolerance of .0002. 

Thrufeed grinding is an application that can be used on many shafts and other parts with single diameter grind requirements. However, thrufeed grinding can be combined with other grinding processes to efficiently complete jobs with multiple surface grind requirements. 

At Melling Industries we can ensure our grind diameters to a roundness of +/- .0002 with our in-line control gaging that is capable of compensating for normal machine variations.
