Millwright Level 1
1. On a pedestal grinder, the gap between the grinding wheel and work rest
should not exceed:: 1/8 inch
2. The kind of abrasive material used in grinding wheels for general purpose
applications is:: aluminum oxide
3. A blotter is used on a grinding wheel to:: protect the flanges from the
abrasizegrit, display information about the wheel and compensate for the uneven
surfaces on the wheel
4. Flanges should at least be:: 1/3 the diameter of the wheel
5. The best wheel to use for cleaning scale and dirt off a workpiece is the:: wire
wheel
6. What is a natural abrasive?: made of natural material rather than
synthetic
7. Under properties of abrasives, to what does the term hardness refer?:
abilityof a material to scratch or penetrate another material
8. The is the part of the wheel that holds the grains together: bond
9. Markings for the wheel identification can be found on the :
Blotter
10. What is the recommended speed to run a grinding wheel?: Never run it
faster that the max RPM of the grinding wheel
11. How should you start a grinder?: Stand off to the side and wait a full minute
,12. Is 46 or 60 the coarser grit?: 46
13. What are the 2 most commonly used abrasive materials?: Aluminum oxide
and silicone carbide
14. For what purpose is the diamond dresser used?: When a very fine finish is
required
15. What is the purpose of ring test?: to check for cracks
16. If a grinding wheel makes a ringing sound what does that mean?: wheel is
not cracked
17. What is the purpose of truing a grinding wheel?: Restores the shape of the
wheel and makes the outer surface of the wheel concentric with its bore
18. An out of balance wheel:: vibrates
19. Belt grinders are useful for:: quickly deburring and chamfering a workpiece
20. What is the purpose of a GFCI?: Senses drop in current and switches power
off
21. The kind of abrasive material use in grinding wheels for general purpose
application is:: aluminum oxide
22. Is it safe to carry a portable grinder by the power cord?: False
23. Is it safe to use standard sockets with electric impact wrenches: False
24. The larger the power drill, the slower the RPMs and the higher the torque-
: True
, 25. Can you use conventional drill bits with a hammer drill? Why or why
not?: Yes of the hammer drill has a switch to turn off hammer action
26. Most cordless drills have torque control: True
27. Prolonged use of power or air tools can cause carpal tunnel sydrome: True
28. Is it safe to run an impact wrench with a universal joint and socket at-
tached: No because it may throw off attachments
29. What conditions would you use a GFCI: Wet conditions
30. What 3 things does a GFCI protect:: 1. Overload 2. Overcurrent 3. Ground fault
protection
31. A GFCI prevents all electrical shocks: False
32. Higher voltage on a battery means:: Greater power of tool
33. What type of power load must be used in the low velocity tool? Why?: Pow-
er load with a crimped end must be used cause high power load would get lodged
in the tool
34. 6 colours ranging from lowest strength to highest strength for power load
are:: 1. Grey 2. Brown 3. Green 4. Yellow 5. Red 6. Purple
35. Power loads should not be carried loosely in pockets or aprons. Why?: -
Could be set off causing serious injury or death
36. Fasteners used in explosive actuated tools are:: Manufactured from special
steel and tempered
37. A drive pin is a fastener used to:: Permanently attach one material to another
38. What is base material?: Material which the fastener shank is driven into
39. To determine the sustainability of a base material, use a fastener as a
centre punch struck by a single average hammer blow. If the fastener is
blunted ( meaning it can't fasten) the material is too:: Hard
