Hard Chrome Grinding
The application of hard chrome (or industrial chrome) has proven itself to be one of the most reliable metal plating solutions available. Chromium coatings provide extreme hardness and resistance to wear and corrosion. This is a major factor in why it is so widely used in industries such as Aerospace, Nuclear, Heavy Machinery and the production of Molding Dies.
But the benefit of increased hardness, also creates another issue of uniformity and meeting project thickness requirements once applied. Which is why you need a certified and proven leader in Outer Diameter (OD) Grinding and Inner Diameter (ID) Grinding like Techmetals. We ensure your hard chrome parts meet precise thicknesses externally, as well as grinding the inside diameter of a part’s cylindrical opening to the exact size and surface finish required.
Our grinding services are in compliance with the industry’s most stringent testing facilities such as Nadcap Chemical Processing, Nadcap Coatings, ISO 9001:2015, ISO 13485:2016, AS9100D, ITAR, FAA Repair Station, 10 CFR App B to name just a few.
The Nature of Hard Chrome Plating
While being electro-deposited onto a substrate, the amounts of hard chrome that covers a part may vary greatly depending upon it’s geometric shape.
The higher areas, elevations and peaks, receive more of a build up of chromium — as well as areas facing the anodes in the plating tanks.
Lower areas, recesses and depressions usually are less thick. Such is the nature of applying industrial chrome.
Hard Chrome Finishes are NOT "Finished" Until Grinding Occurs
Offering both OD and ID Chrome Grinding in-house, Techmetals can obtain almost any required coating thickness.
Typical chrome plating thickness ranges of 0.001″ to 0.002″ as-plated will be only slightly rougher than the base metal.
Our grinding experience allows us to produce surface finishes as low as 1 RMS — which are common in industries such as plastic film and paper converting.
Trust in the company that has over 50 years experience in both Inner and Outer Diameter Grinding. From cylinders used in nuclear energy plants to machine parts and hydraulic equipment, Techmetals is the industry’s proven leader in hard chrome grinding services.
