General Safety PrecautionsPropertyD ofoN Keot ntR Inep duro sdu triace l U1)SASAFETY PRECAUTIONSWhen operation the machine, think about what you are going to do before you do itGo over a safety checklist.1.2.3.4.5.6.Do I know how to operate this machine?What are the potential hazards involved?Are all guards in place?Are my procedures safe?Am I doing something that I probably should not do?Have I made all the proper adjustments and tightenedall locking bolts and clamps?7. Is the workpiece secured properly?8. Do I have proper safety equipment?9. Do I know where the stop switch is?1O.Do I think about safety in everything I do?Clothing, Hair and JewelryWear a short sleeve shirt or roll up long sleeves above the elbow. Keep your shirttucked in and remove your necktie. It is recommended that you wear a shop apron.A shop coat may be worn as long as you roll up long sleeves. Do not wear fuzzy sweaters.If you have long hair, keep it secured properly to avoid your hair being entangledin a moving machine.Remove your wristwatch and rings before operating the machine. These can causeserious injury if they should be caught in a moving part.Hand ProtectionUse a brush to remove chips. Do not use your hands. Resist the temptation to grabchips as they come from a cut. Chips should not be removed with a rag. The metalparticles become imbedded in the cloth and they may cut you.Gloves must not be worn.If a glove should be caught in a moving part, it will be pulled in along with the handinside it.Various cutting oils, coolants, and solvents may affect your skin. The result maybe a rash or possible infection. Avoid direct contact with these products as muchas possible and wash your hand as soon as possible after contact.You may be tempted to blow chips from the machine by using compressed air.This is not good practice. The air will propel metal particles at high velocity.They can injure you or someone on the other side of the machine. Do not blowcompressed air on your clothing or skin. The air can be dirty and the force canimplant dirt and germs into your skin.

PropertyD ofoN Keot ntR Inep duro sdu triace l UIf you are adjusting the machine or accomplishing maintenance, you shouldunplug it from the electrical service. If it is permanently wired, the circuit breakermay be switched off and tagged with an appropriate warning.SAElectrical2)Turning Machine SafetyThe machine can be a safe machine only if the machinist is aware of the hazardsinvolved in its operation. Develop safe work habits in the use of setups,chip breakers, guards and other protective devices. Standards for safety have beenestablished as guidelines to help you eliminate unsafe practice. Some of the hazardsare as follows:1. Pinch points due to movement: Keep your hands away from dangerouspositions, such as gears, chuck or rotating cutters.2. Hazards associated with falling components: Heavy chucks workpieces vises,etc. can be dangerous when accidentally dropped. Care must be used whenhandling them. A chuck wrench left in the chuck can become a missile whenthe machine is turned on. Always remove the chuck wrench immediately afterusing it.3. Hazards resulting from contact with high temperature components:Burns usually result from handling hot chips or a hot workpiece. Gloves maybe worn when handling hot workpiece, but never worn when the machine is running.4. Hazards resulting from contact with sharp edges, corners, and projections:Shields should be used for protection from flying chips and coolant. These shieldsare usually made of clear plastic. Stringy chips must not be removed with barehands, wear heavy gloves and use hook tools or pliers but always turn-off themachine before attempting to remove chips. Chips should be broken rather in astringy mass or long wire. Chip breakers on tools and correct feeds will help toproduce safe, easily handled chips. Burred edges must be removed before theworkpiece is removed from the machine. Always remove the tool bit whensetting up or removing workpieces to avoid culling yourself.5. Hazards of workholding devices: When workpieces are clamped, their componentsoften extend beyond the outside diameter of the holding device. Guards, barriers,and warnings such as signs or verbal instructions are all used to make you awareof the hazards. Never run a geared scroll chuck without having something beinggripped in the jaws. Centrifugal force on the jaws can cause the scroll to unwindand the jaws to come out of the chuck. Keep tool, files and micrometers off themachine. They may vibrate off into the revolving chuck or workpiece, or cutter.6. Spindle breaking: The spindle or workpiece should never be slowed or stoppedby hand gripping or any other means. Always use the machine controls to stopor slow it.

SAPropertyD ofoN Keot ntR Inep duro sdu triace l U7. Workpieces extending out of the lathe should be supported by a stock tube:If a slender workpiece is allowed to extend beyond the headstock spindle a footor so without support, it can fly outward from centrifugal force. The piece will notonly be bent, but it will present a very great danger to anyone standing near.8. Other safety considerations: Hold one end of abrasive cloth strips in each handwhen polishing rotating work. Don’t let either hand get closer than a few inchesfrom the work. Keep rags, brushes, and fingers away from rotation work, especiallywhen knurling. Roughing cuts tend to quickly drag in and wrap up rags, clothing,neckties, emery clothes and hair. Move the carriage back out of the way and coverthe tool with a cloth when checking boring work. When removing or installing chucksor heavy workpieces, use a board on the ways. To lift a heavy chuck or workpiece(larger than an 8-inch diameter chuck) get help or use a crane. Remove the tool orturn it out of the way during this operation. Do not shift gears or try to takemeasurements while the lathe is running and the workpiece is in motion. Never usea file without a handle as the file tang can quickly cut your hand or wrist if the file isstruck by a spinning chuck jaw or lathe dog. Left-hand filing is considered safest inthe lathe, that is, the left hand grips the handle while the right hand holds the tip endof the file.
