In-House Inspection
In keeping with SRP’s commitment to maintaining the highest quality standards in the industry, each machined part is thoroughly inspected prior to shipment to ensure that it meets required tolerances.
Size and Tolerance Capabilities
SRP is equipped to machine parts with up to a 32 inch diameter. We are able to maintain close tolerences of 0.001” can be held on parts under a 15 inch diameter.
Ring roundness can typically be held to less than 0.0015” depending upon the ring wall thickness.
