Another common and overlooked area on stamping presses: is the air supply and exhaust system for the clutch & brake system. In most cases the air supply and clutch brake units are up high and protected with guarding, reason for being overlooked.
As shown in the photo below, Supply tank on right feeds, In-Line oil lubricator to DSV clutch valve to rotary joint inlet to clutch. The tank has a low pressure monitor to prevent clutch wear. The culprit to unneeded brake lining wear can be a dirty exhaust muffler on the DSV valve. If you air system is full of moisture this will contaminate the muffler. When restricted air flow is present, this will cause brake lining wear and longer stopping times. SUGGESTION: DRAIN YOUR AIR TANKS EVERY WEEK AND BE SURE THE MUFFLER IS CLEAN.
