Rollomatic offers a number of upgraded machine models for manufacturing dental rotary cutting tools. The various Rollomatic CNC grinding machines can be used for high-volume geometry grinding and blank preparation of a number of dental cutting tools, such as:

  • Surgical and laboratory dental burs
  • 1- or 2-piece construction, solid tungsten carbide, steel or stainless
  • Gates-Glidden
  • Rotary endodontic files
  • Lindemann cutters
  • Implant twist drills
  • Implant taps
  • Endmills for CAD/CAM dentistry.

"Dental tool grinding on the 5-axis GrindSmart Nano5 grinding machine offers exceptional flexibility in comparison to conventional single-purpose grinders," said a company spokesperson. "With its 5 fully interpolating CNC axes and a pick & place automatic tool loader, the machine can easily be adapted for any type of dental cutting instrument, both for short and long runs."

The spokesperson continued, "Compared to 5-axis machines, the model CNC246F is a prime example of a dedicated and highly productive 3-axis fluting machine suitable for flute and relief grinding of rotary files. The machine is equipped with two grinding stations and a pick & place automatic loader. High productivity can be achieved due to its compact design." The machine is equally suited for flute/relief grinding of drills, taps, reamers and other rotary cutting tools.

The GrindSmart model 530XW 5-axis tool grinding machine, with new capabilities relating to the production grinding of dental burs and rotary files, is equipped with a pick & place automatic loader and a wheel/nozzle changer. The compact and versatile design allows full and user-friendly interchangeability between different tool types as well as industrial tools such as inserts and round-shank tools. The machine is particularly suited for grinding carbide endmills.

"With a choice of 4 and 5 CNC axes, both ShapeSmart NP30 and NP50 precision pinch and peel grinding machines are based on the pinch grinding method, a technology invented by Rollomatic that ensures polished surface finishes and unmatched performances achieving micron precision," said the spokesperson. The machines are particularly suitable for cylindrical grinding or blank preparation of endmills, drills and burs. Quick-change attachments can also be ground with these machines.

The RPG is a hydraulically operated precision plunge grinding machine for cylindrical grinding operations and blank preparations. The machine is equipped with a V-type magazine loader and is therefore suitable for unattended high volume production grinding. The shank guidance and following steady rest allow precise grinding results with a TIR below 1 micron. This machine is recommended for blank preparation of dental burs.

The Rollomatic 5-axis CNC tool grinders are equipped with tool design software called VirtualGrindPro that runs the multi-axis GrindSmart series machines. In addition to the already extensive tool diversity, further tool geometries have been added both for dental tools as well as industrial cutting tools. This software offers enhanced speed, ease-of-use and flexibility. These machines can switch over from dental to industrial tools in an operator-friendly and timely fashion.

In addition to the software expansion, the 3D simulator has been updated with a faster and more accurate version that offers increased stability and instantaneous rendering of 3D images.
