REQUIREMENTS FOR THE SAFE OPERATION OF DRILL
PRESSES
A) SAFETY GLASSES MUST BE WORN AT ALL TIMES WHEN IN THE AREA OF THE DRILL PRESS! Failure to comply may result in revocation of shop privileges.
B) Know how to stop the drill under all conditions before you attempt to start the machine.
C) WARNING!! Loose clothing, long hair, personal stereo wires and jewelry may become entangled in rotating equipment leading to serious injury or death! Make certain that such articles are removed or securely fastened to avoid entanglement.
D) WARNING!! Drill bits, center drills, spot facers, deburring tools, counterbores, and reamers can be extremely sharp. Be aware of the location of the tool when changing workpieces. If you come into contact with the tool, you may get cut severely! Report all injuries immediately!
E) The chips produced through drilling can also be razor sharp and if not properly formed, can be excessively long. Use extreme caution when removing chips! Always use a brush to clean a machine. Do not use compressed air to blow the chips off of the machine or your clothes.
F) Excessively long chips can bunch up, eventually whipping off of the machine. A person in the path of these chips will likely be cut. If you think your chips may be dangerous, stop cutting and get assistance from your supervisor! To avoid dangerous chips, do not force the drill through the workpiece. Occasionally stop drilling and lift the bit out of the drill hole. Stop the spindle and use a brush to remove the accumulated chips if necessary.
G) Never attempt to measure parts or clean the machine while the drill bit is rotating.
H) Before changing tools or drill chucks, make certain that the power to the drive motor is shut down. If you are not sure of the procedure for changing tools or chucks, ask you supervisor for detailed instructions.
I) The spindle must be completely stopped before attempting to change drive belt position on the motor and spindle pulleys. The belt should always be level and not cross from one pulley level to another.
J) WARNING!! Make certain that the workpiece is securely clamped to the table of the drill press. Failure to check may result in items being caught up on the tool bit. These items will spin violently on the tool bit, causing bodily injury! If you are not sure if your setup is safe, have your shop supervisor check it out before you begin cutting.
K) If the workpiece is not clamped to the table, make certain that the workpiece is positioned so that it will swing away from you. Also plan ahead of time how you are going to shut off the drill in an emergency situation.
L) Before powering spindle up, make certain all loose hand tools, drifts, chuck keys, and measuring tools have been removed from the machine and put in the proper location, especially chuck wrenches!
M) Calculate the proper spindle speed before beginning to remove stock. Make certain to use a proper safety factor for the rigidity of the set up and the condition of the tooling. If you are not sure about your calculations, ask your shop supervisor! DO NOT overfeed the tool bit. Tool breakage can occur, sending shards of metal flying at high velocity!
N) If a hole must be drilled over a solid part of the table, place the work on parallels or wood blocks so that the drill does not damage the table when it breaks through the workpiece.
O) Check that locks are off before attempting to change the head height or location. Remember to engage the lock when done!
P) Know how the physical properties of the material being cut affect the way that cut should be done.
Q) Apply all coolants to the tool bit in a safe manner. The use of spray bottles is highly recommended.
R) Watch for oil or grease spilled on the floor. This is an extreme slip hazard and needs to be reported immediately!
S) If the workpiece begins to vibrate, or the cutter makes excessive noise, stop cutting immediately.
If you do not know how to operate a machine or do not fully understand the instructions you have been given, ask a supervisor until you are certain about what is required. IF YOU DON’T KNOW, ASK!
In signing this statement, I acknowledge that I have carefully read and fully understand the serious nature of working with machine tools. I also realize that other, undefined hazards will always exist in the machine shop environment therefore, MY OWN SAFETY IS ULTIMATELY MY OWN RESPONSIBILITY.
