Pump Covers
C & B Grinding Applications
Machine Model: CBH-30-SA/B
Part Name:
Pump Cover
Grinding Operation: We developed a process for these parts on a swing arm machine. A single part is loaded into a blade which advances to the grind position and oscillates between the grinding wheels. The wheels are in a retracted position as the component first enters, then plunge grinds both sides of the part until size is reached. Grinding in this manner provides optimum flatness and parallel and eliminates the possibility of swipes or dubs appearing on the part.
