Dressing and Truing 341

Dressing and Truing provides a guide to performing necessary grinding wheel preparations. Prior to using a grinding wheel, operators must visually inspect the wheel and perform a ring test to check for cracks, and then safely mount, true, balance, and dress the wheel. Each process has specific guidelines or goals, and each step is vital to the success of a grinding operation. To perform dressing and truing properly, operators must first understand the wheel preparation process and its overall purpose. Mounting, truing, balancing, and dressing are crucial to the performance of the grinding wheel and to part quality. Improper dressing or truing can lead to poor surface finish, improper tolerances, scrapped parts, and wheel failure.
