3. AIMS Of STUDY 1.Describe kinds of hands power tools correctly 2.Describe function of hands tools correctly 3.Describe how to use the hands power tools 4.Use kinds of hands tool correctly After finished this study, students must be able to

4. DRIILLING MACHINE Drilling Machine Bench type drilling machine is a kind of the smallest drilling machine.

5. SAFETY WORKS IN USING DRILLING MACHINE 1.Chuck the work piece correctly 2.Use goggles 3.Use overall and keep the hair neatly 4.Check barrier before turning on the switch 5.Pull chuck out before turning the machine on 6.Do not push the handle too strongly when operate the drilling machine 7.Use cooling liquid 8.Turn the speed down when drilling hole will approximately touch the work piece 9. Do not leave the machine in running position 10.Turn off the machine if it is not used Check safety guard of machine

6. GRINDING MACHINES Hand grinding machine : processing to grind work piece using hands Grinding Machine ( Pedestal Type) Caution: Do not push work piece too strong to grinding stone, it caused seriously accident.

7. GRINDING MACHINE SAFETY 1.Use proper uniform 2.Check coverage machine and 3.Use goggles 4.Tighten work piece 5.Check both of drilling stone 6.Stand in one side during turning the machine on 7.Hold the work piece 8.Cooling down the machine periodically. 9.Do not push work piece onto the drilling stone 10.Do not leave the drilling machine while running on 11.Turn off the machine after operated it

8. GENERAL SAFETY 1.Choose the tools based on the works 2.Do not push the tool by hanging the cable only 3.Check power tool before running on 4.Check Power cable in excellent condition 5.Do not let the tool stop running 6.Avoid using electric power tools at wet place 7.Keep working area clean and free barrier. 8.Turn the switch off after operated it 9.Check covered cable or pipe inside the wall 10.Keep the way free from cable

9. POWER SOURCES Bor Portable (Double Insulated) Power source for portable power tools is electricity110/220 volt. Power tools modern has covered by doubled insulated and usually does not need grounded cable

10. PORTABLE ANGLE GRINDER Angle grinder Angle grinder is structured to uncovered steel material using disc abrasive plate or drilling stone. Construction of drilling stone 1.Tighten the drilling stone for safety working 2.Drilling stone can operate into 10 000 revolution/minute (RPM 10.000). Function: 1. To grind steel in fabrication

11. CUTTING GRINDER Cutting grinder is portable grinding machine using special thin abrasive grinding stone. Cutting grinding machine and its place Self protection requirements: 1.Face safeguard 2.Ear plugs or ear muffs 3. Safety boots

12. ELECTRICAL PORTABLE NIBBLER Electrical Portable nibbler is constructed to cut and to shape steel bar Electrical Portable nibbler Caution: Overload is prohibited Function: 1. To cut multi shape material

13. ELECTRICAL PORTABLE JIG SAW Electrical portable jig saw Jig saw move s up and down in 2500 strokes/minutes Caution: Avoid using over whelm Jig saw is used to cut multifarious wood or steel material.

14. BATTERY SUPPLY Battery supply : is used as power supplies for portable power tool. It is called by battery packs. Portable drilling Machine, Power Pack, and Charger.

15. CORDLESS SCREW DRIVER Cordless screw driver Advantage : Is used to operate machine at no power area or wet and moisture area. Caution: Avoid using power tool overwhelming it caused broken out.

16. PNEUMATIC Advantages: 1.Having long term power 2.Air supply is filtered relatively clear, regularly and lubricating. Disadvantage: : Require a big capacity air compressor for supplying air. Function: Is used in contraction building, vehicle, and component fabrication assembling. Air Portable compressor

17. Supplying air to a power tool through regulator and lubricator Caution: Pneumatic tools is normally controlled by motor of air compressor AIR SUPPLY

18. PORTABLE PNEUMATIC DRILL Portable Pneumatic Drill -It is operated using air compressing. -This type is used to drill air plane, automotive, and bar steel fabrication.

19. PNEUMATIC KEY Impact able pneumatic key ( gun Type) Function: Is used in automotive fabrication for tightening and loosing screws. Pneumatic Key uses impact able devices that help to loose or tighten the screws

20. PNEUMATIC HAMMER Function: 1.To support swing or hit with the average 500 times/minutes or more 2.To break material for examples : to break stone, and mixture. Pneumatic hammer This device is constructed to save time and operator power more than using hand

21. PNEUMATIC DISC SANDER Function: To sander and to clean wood and steel material Pneumatic disc sander Self protector 1.Face shield 2.Ear plugs 3.Safety boot

22. SAFETY WITH PNEUMATIC TOOLS Ear muffsEar plugs Goggles Safety glasses Respirator Machine Guards: Must be assembled to machine to protect the operator or worker.

23. MAINTANAINCE OF Portable Power Tools Check the tool Labeled the broken part

24. 1. Do not operate in overloading capacity 2. Clean and check the tools regularly 3. Check ventilation hole from barrier 4. Change or fix the casing. 5. Do not use power tool using broken cable power supply. 6. Label the broken part 7. Lubricate the power tool HANDLING AND MAINTANANCE Portable Power Tools

25. HOLDING WORK 1.Do not handle the work piece using one hand 2.Do not operate power tool using one hand 3.Power tool must hand tightly to avoid accident. 4.Ask for help if necessary. Use chuck to hold the work piece

26. Use vice to hold work piece to avoid accident. HOLDING WORK DO NOT DO THIS!

27. Exercises: 1.Mention kinds of power tools ! 2.Mention two advantages using cordless power tool! 3.What does consider to choose power tool? 4.Mention and explain the advantages of pneumatic key? 5.Mention two fabrications that use pneumatic tool !

28. There are some kinds of Hand and Power Tool that used in factory: 1. Drill machine 2. Grinding machine 3. Portable drilling machine (double insulated) 4. Portable angle grinder 5. Cutting off grinder 6. Electrical Portable nibbler 7. Electrical Jig Saw 8. Cordless screw driver 9. Air Compressor (Pneumatic) SUMMARY 10. Portable pneumatic drill 11. Pneumatic Key 12. Pneumatic Hammer 13. Pneumatic Disc Sander
