Carr Lane Mfg. Co. offers a new LIFE-EX™ PVD coating as an option on its round and diamond pins. So hard it cannot be measured on the Rockwell C scale, LIFE-EX is a thin film of vaporized solid metal that has been deposited onto Carr Lane’s round and diamond pins as a pure metal or alloy coating.
“We are very excited to introduce this industry exclusive coating in a standard stocked product. For our customers working with very abrasive or hard materials like exotic alloys and carbon fiber, the LIFE-EX coating will help their locators have a longer service life due to its very high hardness,” said Colin Frost, COO. “Customers running large quantities of items through a tool will also extend the service life of the locators with LIFE-EX because it is not only very hard but also provides extra lubricity when compared to hardened steel.”
LIFE-EX provides a uniform deposit, and is available on three sizes of inch or metric pins. These precision locating pins have a chamfered tip for easy part loading, and a shoulder to resist downward forces, making them more efficient than dowel pins. One round pin and one diamond pin are often used together to locate from two machined holes in a workpiece, or to align two pieces of a fixture, without binding.

- abrasive
abrasive
Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.
- alloys
alloys
Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
- fixture
fixture
Device, often made in-house, that holds a specific workpiece. See jig; modular fixturing.
- hardness
hardness
Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.
- lubricity
lubricity
Measure of the relative efficiency with which a cutting fluid or lubricant reduces friction between surfaces.
- physical vapor deposition ( PVD)
physical vapor deposition ( PVD)
Tool-coating process performed at low temperature (500° C), compared to chemical vapor deposition (1,000° C). Employs electric field to generate necessary heat for depositing coating on a tool’s surface. See CVD, chemical vapor deposition.
