Description:
The Brass Centering Pin with Water Hole is a precision component designed for use in faceting and lapidary equipment, particularly on flat lapping machines and diamond pad systems. This pin is constructed from brass, a non-ferrous metal chosen for its durability, corrosion resistance, and ability to thread securely without damaging precision equipment. The pin features a 5/8 inch-11 thread specification that allows it to thread directly into the center of the shaft on your lapping equipment. A central hole runs through the entire length of the pin, creating a water passage that allows coolant or water to feed through the shaft and disperse from the center of the diamond pad plate. This water distribution system is essential for maintaining proper cooling and lubrication during extended faceting and polishing operations, helping to prevent heat buildup and extend the life of your diamond pads.
How it is used:
The Brass Centering Pin with Water Hole threads into the center of your lapping machine shaft, where it serves dual purposes. First, it centers your diamond pads on the working surface, ensuring even contact and consistent cutting action across the entire pad. Second, the water hole allows you to run a water line through the shaft, with water dispersing from the center of the pad to cool the work piece and the diamond surface during operation. This is particularly important in faceting work where precision and consistent results depend on maintaining stable temperatures and proper lubrication. The pin should be threaded firmly into place but not over-tightened, as the brass material is designed to provide secure holding without risk of stripping the threads.
