The Efficient Solution for Exact Finishes

Honing is the ultra-precise machining process trusted by job shops and high-production manufacturers to create parts that perform at the highest levels of speed and efficiency. No boring or grinding process is capable of delivering such fine levels of roundness, straightness and surface detail. When integrated into your manufacturing process, honing is the difference between a part that works and a part that performs.

Honing is a three-in-one metalworking process that:

  • Removes excess metal stock
  • Reinforces straightness, roundess and size
  • Creates a crosshatch finish for optimal lubrication

Machines that Work Harder. Accessories that Last Longer.

Our reputation is built on quality and durability. You’ll find Sunnen machines from the 1940s that are still running strong to this day. Over the years, we’ve applied our expertise with emerging technologies to develop the industry’s largest catalog of bore finishing machines. We also offer all the tools, accessories and training necessary to sustain a high-performance honing operation.
