Rollomatic’s grinding machines for dental burs, rotary instruments

Rollomatic, a leading machine tool manufacturer based in Le Landeron, Switzerland, maintains its global leadership position in the dental industry by highlighting a range of upgraded models for manufacturing dentals rotary cutting tools. The various Rollomatic CNC grinding machines can be used for high-volume geometry grinding and blank preparation of various 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 Nano5grinding machine offers exceptional flexibility in comparison to conventional single-purpose grinders. With its 5 fully interpolating CNC axes and a pick-and-place automatic tool loader, the machine can easily be adapted for any type of dental cutting instrument, both for short and long runs. Compared to 5-axis machines, the model CNC246F is a prime example of a dedicated and highly productive 3-axis fluting machines suitable for flute and relief grinding of rotary files. The machine is equipped with 2 grinding stations and a pick-and-place automatic loader.

Highest 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 and innovative capabilities relating to the production grinding of dental burs and rotary files is equipped with a pick-and-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 for the CAD/CAM dentistry.

With a choice of 4 and 5 CNC axes, both ShapeSmart NP30 and NP50precision pinch and peel grinding machines are based on the proven method of pinch grinding, a technology invented by Rollomatic, that ensures polished surface finishes and unmatched performances achieving micron precision. The machines are particularly suitable for cylindrical grinding or blank preparation of CAD/CAM 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 1micron. This machine is highly recommended for blank preparation of dental burs.

The Rollomatic 5-axis CNC tool grinders are equipped with tool design software called VirtualGrindPro which 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. Rollomatic’s strategy with this expansion is based on helping operators and programmers to facilitate an environment of efficiency and collaboration within the user’s organization. This powerful software offers the highest possible 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 3-dimensional simulator has been updated with a faster and more accurate version. The impressive stability and instantaneous rendering of 3D images will enable users to save valuable programming time and effort.
