15 Oct Grinding Lesson

The main purpose of surface grinding is to produce:

• Circular surfaces

• Flat or irregular surfaces

• Threaded surfaces

• Conical surfaces

In surface grinding, the workpiece is passed under a:

• Stationary cutting tool

• Rotating abrasive wheel

• Stationary abrasive pad

• Milling cutter

Which of the following is not a typical work surface produced on a surface grinder?

• Step block

• Vee block

• Cylindrical shaft

• Guide block

A surface grinder is primarily used to achieve:

• Rough finishes

• Fine finishes and accurate dimensions

• Deep material removal

• Internal bores

What material is most commonly used for the grinding wheel?

• Diamond

• Abrasive materials

• High-speed steel

• Carbide

The purpose of coolant in grinding is to:

• Increase wheel wear

• Reduce heat and improve finish

• Harden the wheel

• Slow down spindle speed

Which block is typically ground to ensure 90° accuracy on all faces?

• Vee block

• Step block

• Rectangular block

• Guide block

The abrasive wheel in a surface grinder rotates:

• Linearly

• On a vertical or horizontal spindle

• Along the X-axis only

• Randomly

Grinding removes material through:

• Plastic deformation

• Cutting action of abrasive grains

• Melting

• Hammering action

Which of the following indicates a smooth and flat finish?

• Visible tool marks

• Smooth and flat finish

• Wavy patterns

• Burn marks
