Production Process Of Grinding

By: Phanawn Bailey & Alex Naegele

What is Grinding?

Main Types of Grinding

Visual aid and Questions?

  • Surface grinding
  • Belt grinding
  • Cylindrical grinding
  • Form grinding
  • Plunge grinding
  • It is an abrasive machining process

Abilities:

  • is an economical method for cutting hardened steel
  • Produces a smooth surface
  • Can easily shape brittle material

Belt Grinding

Surface Grinding

Form Grinding

Plunge Grinding

Cylindrical Grinding

Typically used to grind cylindrical surfaces and shoulders of work materials

  • external grinding
  • internal grinding

Surface grinding uses an abrasive wheel to remove material

  • multiple shoulders
  • multiple diameters
  • irregular shapes

Form grinding requires a specialized grinder that results in the shape finished product

Uses an abrasive belt to remove material

Material Properties

Grain Size

  • coarse grains remove material faster
  • fine grains give a finer finish
  • wearing away softer materials than itself
  • different materials have different abbrasives
