TOP HAT ROLL BURNISHING

TOP HAT ROLLER BURNISHING TOOL FOR CONTOURS & PROFILES

In applications where you need to generate a surface finish on a contoured profile, options are limited and the cost normally much higher. The Elliott top hat roll burnishing tool is perfect for these applications.

Monaghan and Elliott have been supplying OD carbide roll tools for decades, with many thousands of successful applications burnishing just a single diameter, or complex profiles with contours, tapers, blend radii and faces included. The tools can be used on a wide variety of materials and offer a versatile and low-cost solution for generating a quality surface finish.

OD PROFILE BURNISHING ADVANTAGES

LOW MICROINCH FINISH

  • Produces a 4 to 8 Ra surface finish in one pass.
  • Improves surface irregularities and tool marks.

PROCESS IMPROVEMENTS

  • Burnishing is a repeatable and consistent process
  • Fast cycle times – measured in seconds, not minutes!

VERSATILITY

  • Burnishing is effective for many different part configurations.
  • Suitable process for a variety of metals – all ductile metals can be burnished!

LOW COST

  • Eliminates secondary machines and set ups.
  • Eliminates secondary processes such as grinding, honing and polishing.
  • Elliott burnishing tools feature long lasting and replaceable wear parts, reducing total cost over the life of the tool.
  • Rolls can be reconditioned

WORK HARDENING

  • Burnishing increases the surface hardness through the cold working process and compressive forces.
  • Increases metal’s resistance to fatigue and failure at stress points.
  • Produces a dense and uniform surface.

PROVEN QUALITY

  • The burnishing process has been refined and improved  for over 100 years and has a proven record of success.
  • Monaghan Tooling Group and Elliott Tool Technologies continue this long tradition by providing the industry’s highest quality burnishing tools.

EASY-TO-USE

  • MTG and Elliott burnishing tools require limited training to operate.
  • Easy to maintain and repair.
  • Common repair parts are always stocked!
