Cylindrical Grinding

What Types of Parts are Good Candidates for Cylindrical Grinding?

Cylindrical grinding was created over a century ago and enabled high precision parts to be fabricated with the use of friction and pin-point design.  Essentially, any part that requires boring or grinding can be made through cylindrical grinding.  Everything from car hubcaps to grip texture can be made.  The military uses cylindrical grinding in machining aircraft tools and instruments.  Baseball bats are also commonly made through cylindrical grinding; a simple wooden stub is rotated on an axis and reduced to a seamless form through computer guided grinders.

Designing Parts for Cylindrical Grinding

To meet the standards of true cylindrical grinding, 4 rules must be applied:

  1. The work (object) must be constantly rotating
  2. The grinding wheel must be constantly rotating
  3. The grinding wheel is fed towards and away from the work
  4. Either the work or the grinding wheel is traversed with the respect to the other

Sourcing Cylindrical Grinding

The use of a cylindrical grinder requires proper training and safety.  This means that you will not find one in your local wood or machine shop.  It is also a very expensive piece of equipment to maintain; parts, repair, and routine maintenance.  Most machines utilize computers, which also require a proper knowledge to operate.  Most tradesmen will either know someone or know themselves how to operate a cylindrical grinder properly. They will most likely also have a certification granted by a safety organization such as NIMS (National Institute for Metalworking Skills).  Many current models of grinders have interchangeable parts to create an all-in-one metalworking machine that can do several things at once.
