24
Q

What are the grades of cuts of a file
(All 6 from roughest to smoothest)

A

Rough with 10 to 15 teeth per inch.

Middle Cut with 15 to 20 teeth per inch.

Bastard with 20 to 30 teeth per inch.

Second Cut with 30 to 40 teeth per inch.

Smooth with 50 to 60 teeth per inch.

Dead Smooth with 80 to 120 teeth per inch

25
What are the common types of double Cut files
Flat Hand Warding Three square Half round
26
Difference between hand and flat file
Flat has taped end and has single cut on both edges Hand is flat (not tapered) and has 1 safe edge with no cuts
27
What is used to clean a file
File card (scratch card)
28
What are the 3 hacksaws
Hand (normal) Spring bow (junior) Pad saw (sawing in awkward positions)
29
What 2 metals are used for hacksaws
Low alloy steel High speed steel
30
What do the colours of the hacksaw blades mean?
BLUE - All Hard high speed steel blade. Best cutting blade, but tends to shatter if abused in any way.  ORANGE - Bi metallic high speed steel blade. Has cutting ability of a blue blade but virtually unbreakable in use.  RED - Flexible high speed steel blade. Softer than a blue blade so it tends to wear out quicker, but is more difficult to break.  SILVER - Low Alloy steel blade. Impractical to use on steels because it wears out so quickly, so is generally used on softer materials such as plastics etc
31
What are the 3 hacksaw sets
Raker (middle peice straight every 3rd) Alternate (angle) Wave
32
If material is the only consideration, what type of blade should you use for soft and hard materials
Soft - lower TPI to give adequate chip clearance which prevents clogging Hard - higher TPI to give sufficient cutting points in contact with work
33
What are the 3 main parts of a drill
Point(cutting edge) Body(between point and shank) Shank(portion that fits into chuck or socket
34
What is the lip angle, heel angle and lip clearance
Lip - 59⁰ x2 (or 118⁰) Heel - 12⁰-15⁰ Lip clearance (125⁰-135⁰)
35
Does the chisel edge of a drill cut the material?
No, it forces its way through, the cutting edges cut the material
36
What is used to remove a tapered Shank from a tapered socket?
Morse tapered drift to remove from spindle
37
Using a micrometer, where would you measure a NEW drill piece? And where would you measure an old drill piece?
New - as close as possible to the point Old - across body close to the end of the flutes
38
What are the 6 different types of reamers
Hand Machine Straight or parallel Tapered Adjustable Expandable
39
When using a reamer, how can chatter be reduced?
Odd number of flutes
40
What way should you turn a right handed reamer and what way should you turn a left handed reamer?
Both should be turned to the right (clockwise)
41
What is the difference between left and right handed reamers
Left - best suited for most work, helix resists feed of reamer for a better feel (more desirable) Right - feeds into work and advances quicker. Can cause cutting edges to take more of a cut than they can stand
42
What is the screw angle of most screws and what is the angle of the other one
60⁰ for most screws except Whitworth as they are 55⁰
43
. What is the order of threads used to make an internal thread
Taper tap to start the thread Intermediate tap to follow the holes that are not completed by the taper tap Bottoming tap (plug tap) to complete thread
44
What are the 3 types of dies?
Button die (split in one side) Two piece die (adjustable) Die nut (used for fixing threads, not cutting)
45
What does double installation mean?
The international symbol for double insulation is a square within a square. This symbol is shown above. An appliance labelled with this symbol has additional insulation between any exposed metal parts and the insulation of the current￾carrying parts, hence the term “double insulation”
46
What's the difference between milling machine and drill press
Milling machine has the drill stationary and the piece moves where as drill press the piece is stationary and drill moves down onto it
47
What is the maximum clearance between grinder and work rest
2mm
48
What is glazing?
When the wheel abrasive particles becomes dull from being used on too hard a surface with strong bonds
49
What is a prick punch angle and a centre punch angle
Prick (60⁰) Centre (90⁰)
50
What is a drift
Used with a hammer to localise a blow to an object without damaging the object
51
What is a starter (taper) punch and a pin punch?
A starter punch is used first to start/jar loose taper, parallel pins and rivets Pin punches is a Cylindrical punch used to drive previously loosened locating or locking pins, dowels and rivets put of their holes
52
What are the different types of headset of a screwdriver
Slotted Cross slot/ Phillips Pozidriv (Phillip with star) Tri wing Torx
53
What are the different types of pliers
Circlip pliers - used to remove circlips Combination pliers - standard engineer pliers Diagonal cutting (side cutters) - making flush cuts on smaller things, not for holding Long nose - reach far places Duck bill - bend ligh sheet metal Water pump/ slip jaw - powerful grip and can adjust several different sizes Safety wire - aviation,used for wires Self grip/ lock grip/ vice grip - locks
54
What is a spanner called with 2 open ends?
Double open end spanner
55
What is a spanner called with 1 side open and 1 side a ring
Ring open end spanner
56
What is a flair nut spanner
Similar to an open ended spanner but used with flair nuts. Ribbed inside
