CNC Grinding of Stainless Steel Piston Rod Sleeve for the Air & Gas Compressor Industry

When Groundim XI Precision Grinding was contacted by a client to manufacture this featured piston rod sleeve for use within a compressor application, we rose to the challenge. Adhering to our client's standards as laid out in a customer-supplied print and a 2D CAD drawing, we began CNC inside and outside diameter grinding with a carbide grinding wheel. We used 416 stainless steel as our primary material, and held tight tolerances, down to +/- .0002 of an inch, with a parallelism tolerance of +/ .0005 of an inch, cylindricity tolerance of +/- .0002 of an inch, and a true position of +/- .0005 of an inch.

Each final piston rod sleeve measured 2.700 inches in outside diameter, 1.25 inches in inside diameter, 8.06 inches long, and featured a .360 of an inch wall thickness with a .030 of an inch by 45 degrees chamfer at both ends. We achieved a Brinell BHN Hardness of 375-400 and a 12-16 RMS surface finish. When we were certain we had surpassed our client's expectations for quality and precision, we delivered the order of 25 piston rod sleeves to our client in Oakland, California, where they were put to use within a high-pressure air and gas compressor application.
