- | __Start With A Risk Assessment To Ensure A Safe Work Area:__ | + | TODO: FINISH THIS |
- | - A two foot perimeter around the drill press should be kept clear of people, debris and sawdust that impair traction or footing to avoid slips and falls. | + | |
- | - Safety glasses with side shields or a face shield must be worn. Hearing protection should be worn. | + | |
- | - Remove loose fitting clothing, jewelry, and tie back long hair. | + | |
- | - Give the work your undivided attention. | + | |
- | - Do not wear gloves or anything that would allow a hand, fingers or clothing to be wrapped around the revolving bit. | + | |
- | __Operational Safety Rules:__ | + | ======= Shut down ========== |
- | | + | |
- | | + | |
- | | + | |
- | - Make sure the size of the bit is equal to or less than the capacity of the drill press. | + | |
- | | + | |
- | - Center punch the drill-hole location into the stock. | + | |
- | - Insert bit into drill chuck and tighten with the chuck key. REMOVE CHUCK KEY FROM THE DRILL CHUCK BEFORE STARTING THE DRILL PRESS | + | |
- | - Use a clamp or vise to securely fasten the stock to the drill press table. Never attempt to handhold stock less than 3’ long while drilling. | + | |
- | | + | |
- | | + | |
- | - Support the underside of the stock to be drilled with a backer board secured to the drill press table. DO NOT DRILL INTO THE DRILL PRESS’ TABLE, except for the existing hole in the centre of the drill press table! | + | ====== PCB Milling ====== |
- | | + | |
- | - Keep hands and fingers at least 3” from rotating drill bits. | + | See [[PCB Milling With Sherline]]. |
- | - When drilling deep holes, frequently raise the drill bit from the hole and use a chip brush to remove cuttings and allow the cool bit to cool down. | + | |
- | | + | |
- | - If a drill bit binds, turn off the drill press and carefully turn drill chuck backwards by hand to free the drill bit. | + | |
- | - Never reach around or under a rotating drill bit or grab the chuck to stop a drill press. This can result in hand puncture or other serious injury. | + | |
- | - Turn the drill press off before looking up or walking away from the machine. | + | |
- | - Never stop the rotation of the drill chuck, spindle, or uncontrolled stock rotation when jammed on the bit with your hands or fingers. | + | |
- | - Don’t touch the drill bit and shavings since they are hot immediately after drilling. | + | |
- | - Always clean the work area in the machine upon completion of the milling task. Do not use your hands or blow the shavings, use a chip brush. | + | |
- | - When milling into metal use a coolant oil (WD-40 often works well) and use the appropriate speeds and feeds. Rags or chip brushes saturated with cutting oil should be disposed of in a fire can or outside in the dumpster. Never place oil saturated material in the interior garbage cans within the space! | + | |
