TYPES OF GRINDING MACHINES From the simplest grinding machine to the most complex, grinding machines can be classified as utility grinding machines, cylindrical grinding machines. and surface grinding machines. The average machinist will be concerned mostly with floormounted and benchmounted utility grinding machines, bufting machines. and ...
UNIT 6: Grinding machines: Types of abrasives, bonding process, classification, constructional features (cylindrical and surface grinding), Selection of grinding wheel. 6 Hrs Instructional Objectives: At the end of this lesson the students would be able to Understand basic principle of grinding. Recognize purpose and application of grinding.
Grinding flat or plane surfaces is known as surfaces grinding. Two general types of machines have been developed for this purpose; those of the planer type with a reciprocating table and those having a rotating worktable. Each machine has the possible variation of a horizontal or vertical positioned grinding wheel spindle. The
