Grinding machines are used for smooth metal surface finish as well as quality accuracy of shape and dimensions. Machines are widely used in fabrication fields. Metal finishing ranges from 0.25 to 0.50 mm in most operations with high accuracy. 

How to Maintain the Machining Process Surface.

TYPES OF GRINDING MACHINES

The types of grinding machines are according to the smooth surface of all conceivable shapes and materials of all kinds they are two types.

  1. ROUGH GRINDERS
  2. PRECISION GRINDERS

Types of Stresses of a materials

ROUGH GRINDERS

Rough grinder machines are mainly used for chief work is the removal of stock without any reference to the accuracy of the results.

Rough grinder machines are four types they are.

  1. Abrasive belt grinders
  2. Floor stand and bench grinders
  3. Portable shaft grinders
  4. Flexible shaft grinders
  5. Swing frame grinders

Abrasive belt grinders

Abrasive belt grinders are widely used in industry as the technique of manufacturing the belts improves. These grinders are used for light polishing work. The grinding machines may be Dry belt, Wet belt and combination belt type.

Floor stands and bench grinders

Floor stand and bench grinders are simplest type of machines. A small size machine mounted on a bench is called bench grinders.

These grinding machines are used for snagging and off- half hand grinding of tools and miscellaneous parts.

 Portable shaft grinders

Portable shaft grinders are usual form of portable grinder resembles an electric hand drill with grinding wheel mounted on the spindle. Heavy tools of these kinds are used for roughing and snagging and small ones for burring and die work.

Types of Measuring Instruments used in Production

PRECISION GRINDERS

Precision grinders are those that finish parts to very accurate dimensions. According to the type of surface work done they are classified into 5 Types.

  1. Special grinding machines
  2. Surface grinding machines
  3. Cylindrical grinding machines
  4. Internal grinding machines
  5. Tool and Cutter grinding machines
