Which grade of surface plate is used for toolroom work?
Grade A
Grade AA
Grade B
Grade C
What is the main disadvantage of cast iron surface plates compared to granite?
Limited shape and size
Higher cost
Easily rusts with moisture
Granite surface plates are preferred because they:
Are lighter than cast iron
Do not rust and absorb vibrations well
Are easier to machine
Have higher thermal expansion
What should be done before and after using a surface plate?
Apply oil coating
Clean with soap/water or alcohol
Spray paint
Sand the surface
Which type of cleaner is commonly used for granite surface plates?
Acid cleaner
Pink liquid cleaner
Diesel
Chlorine
What is the purpose of surface plate covers?
Prevent rusting
Prevent abrasive build-up
Make it look attractive
Make it heavier
Which of the following is NOT a common accessory for surface plate?
Vernier height gauge
Dial gauge
Lathe chuck
Gauge block
What is the function of an angle plate on a surface plate?
To polish the surface
To check roundness
To hold workpiece vertically
To measure depth
A V-block is primarily used to:
Hold square workpieces
Check roundness of cylindrical workpieces
Measure angles
Check flatness
Which of the following errors can occur if a height gauge is not calibrated?
Heat distortion
Inaccurate measurement
Tool breakage
Rusting
Which guideline is correct for using a vernier height gauge?
Move it roughly and fast
Lock the main scale when in use
Do not clean before use
Avoid calibration
What is the effect of burrs and dirt on a surface plate?
Improves flatness
Causes poor readings and wear
Increases durability
Reduces weight
16. Which property of granite makes it suitable for surface plates?
High hardness and wear resistance
Low thermal conductivity
High porosity
Magnetic properties
Why should unnecessary tools not be placed on the surface plate?
May cause scratches and errors
May improve accuracy
To save space
To reduce weight
Which of the following statements about surface plate accessories is correct?
They must be kept clean and free from burrs
They can be used without cleaning
Flatness is not important
Calibration is unnecessary
Which of the following absorbs heat slower but dissipates slower too?
Cast iron surface plates
Granite surface plates
Aluminium surface plates
Steel surface plates
What is the correct action when not using a surface plate?
Leave it uncovered
Cover it with a vinyl cover
Store heavy tools on it
Apply grease
