GRINIDING MACHINE

What factor influences the grinding allowance in grinding machines?

• The material of the grinding wheel

• The type of coolant used

• The required accuracy, size of workpiece, and previous machining operations

• The speed of the grinding wheel

What type of wheel is commonly used on a typical horizontal spindle reciprocating-table grinder?

• Round-shaped wheel

• Straight-shaped wheel

• Conical-shaped wheel

• Cylindrical-shaped wheel

What is the function of the adjustable dogs (4) on a horizontal spindle reciprocating-table grinder?

• To set up the speed of the grinding wheel

• To adjust the depth of cut

• To reverse the table travel at the ends of the stroke

• To secure the workpiece on the table

What is the purpose of the T-slots on the table (2) of a horizontal spindle reciprocating-table grinder?

• For adjusting the speed of the table

• For clamping workpieces directly or clamping grinding fixtures or a magnetic chuck

• For mounting the grinding wheel
  

• For controlling the hydraulic flow

What is the main characteristic of Creep Feed Grinding (CFG)?

• The workpiece is fed quickly past the wheel

• A shallow depth of cut is used

• The wheel is not dressed continuously

• A large depth of cut (1–6 mm) is taken in a single pass

Which type of machine is primarily used for grinding external cylindrical surfaces, such as crankshaft bearings, spindles, and shafts?

• Surface grinding machine

• Cylindrical grinding machine

• Pedestal grinder

• Bench grinder

In traverse cylindrical grinding, how does the grinding wheel move?

• It only rotates about its axis

• It rotates and moves intermittently in a crosswise motion at the ends of the traverse stroke

• It only moves longitudinally

• It does not move, only the workpiece moves

What is one of the difficulties encountered in internal grinding due to the small size of the grinding wheel (GW) and spindle?

• The reduced rigidity of the small spindles makes it impossible to take heavy cuts

• The inability to rotate the wheel at high speeds

• Excessive coolant usage

• The workpiece cannot be fed through the machine

When is grinding typically performed in the manufacturing process?

• It is usually the first operation

• It is one of the final operations performed on manufactured products

• It is performed at random stages of manufacturing

• It is only performed during rough machining

What is abrasive machining primarily used for?

• Cutting metals only

• Finishing hard materials and hardened steels

• Only for cleaning surfaces

• Polishing plastics
