Nifty-Bar, Inc. specializes in double disc grinding applications. Our array of double disc grinders includes oscillating feed, rotary feed, and thru-feed equipment suitable for a wide variety of high precision applications.

Double Disc Technology

With double disc grinding technology, parts are passed one or more times between two counter-rotating grinding wheels. Double disc grinding removes material from both sides of the part at the same time providing surfaces that are flat and parallel in one operation. This technology can be used for economical production of one of a kind parts through millions of parts per year.

Speed and Economy

For rotary feed and thru-feed applications, parts can often be completely processed at high speed in a single pass through our equipment for quick turnaround and maximum economy

Our oscillating feed equipment can be used for large parts and for applications that require more material removal than is practical with rotary feed or thru-feed equipment.

Dimensional Control

Double disc ground parts can be precisely controlled for thickness while achieving superior surface finishes. Even difficult to grind materials such as inconel and
titanium can be ground flat and parallel through double disc grinding since parts
are processed by the flat surfaces of the wheels instead of by wheel edges. Double disc grinding can also be used to produce products with very thin cross sections
while minimizing part stress.

Diverse Applications

Double disc ground materials and components are used for many diverse applications including:

  • Blades and Knives
  • Component Part Blanks
  • Connecting Rods
  • Cutters and Dies
  • Extrusions
  • Gages
  • Gears and Gear Blanks
  • Laminations
  • Shims and Spacers
  • Stampings
  • Substrates
  • Valve Plates

Combined Capabilities

For products requiring heavy material removal to achieve the final dimensions, we can combine our Blanchard grinding and double disc grinding capabilities to provide the most economical approach for your project.
