Machine Tool Practices, 11e (Kibbe)
Section B – Hand Tools
1) Two basic principles always taken into consideration by persons familiar with the proper use
of shop pressers are:
A) Personal safety and the care of the workpiece to prevent it from being damaged
B) Care not to overload the press by tying to press an oversized part and personal safety
C) Always use the largest press available for every job as the part being pressed might stick half
way through with a small press. Personal safety
D) Care should be taken not to press too fast, as this creates friction which produces heat
2) You can use the arbor press or shop press to:
A) Drill holes in metal parts
B) Install and remove mandrels, bushings, bearings and shafts
C) Make keyseats on shafts
D) All of the above
3) An arbor press designed with a rack and pinion is what type?
A) Hydraulic
B) Mechanical
C) Gear driven
D) Hydro-mechanical
34) To avoid failures from seizing when pressing a shaft or mandrel, you should:
A) Press them together dry
B) Apply a high– pressure lubricant to the bore and shaft
C) Use a good grade of lubricating oil on both parts and don’t stop after you start pressing
D) Used sulfurized cutting oil on both parts
45) A loose arbor press ram may cause:
A) A keyway broach to “hog” in or a bushing to twist out of alignment
B) A loss of pressure making it difficult to force a broach through the work
C) Keyway broach to twist and cause an excessively wide keyway and a mandrel to “hog” in half
way through the bore
D) None of the above
56) The amount of pressure you should apply to a bushing in an arbor press would be:
A) Just the amount needed to push it through the bore and then considerablye more force applied
to make sure it is seated
B) About 5 tons
C) Between 10 and 30 tons
D) Just the amount needed to push it through the bore and when slight additional pressure is felt,
stop pressing
67) A ball bearing that is on a shaft or in a housing should be removed:
A) By applying pressure only to the race that is supported securely
B) Only by pressing on the inner race when the outer race is in a housing or by pushing on the
outer race when the inner race is on a shaft
C) By pressing on and supporting any part of the bearing that is available
D) B and C above
78) A mandrel will slip into a bore on one of its ends. Why then does it press tightly in a bore?
A) It is made very slightly tapered so that it is somewhat larger at one end
B) It has been made rough by a knurling process in the center thus enlarging it slightly
C) The high– pressure lubricant applied to its surface causes the bore to tighten
D) It is made in a “barrel” shape so that it is slightly larger in the center that at the ends
89) What two important things should be done before pressing in a bushing?
A) Oil the bushing and start it in the bore with a hammer before you start pressing
