Implanting success

High-performance grinding machine

The GrindSmartNano5 was specifically developed for dental tools; however, it is also suitable for series production of other applications, such as dental burs, standard cutters, and Lindemann milling tools, as well as endodontic files and reamers.

To cover such a wide range of tools, the GrindSmartNano5 comes with different tool guide systems to suit the application. One such system, which is designed especially for dental burs, clamps the tool directly behind the head in order to achieve maximum stability during the grinding operation. The second tool guide system is suitable for manufacturing standard drilling and milling tools whose tool head diameter is smaller than the shank. For tools with long cutting length, such as endodontic files and reamers, a steady rest is available to prevent the tool from bending during the grinding process.

Changing from one tool guide system to the other and reconfiguring the machine only takes a few minutes.

Rollomatic also has integrated an automatic robot loader into the system in order to equip it for series production. Batch sizes of up to 1,000 pieces can be machined without operator intervention. Designed for maximum efficiency, the machine features short axis movements and a high-speed loading system that loads and unloads the workpiece in just a few seconds, resulting in significantly shorter cycle times compared to other grinding machines.

Float away misalignments

The Preci-Flex Compensating Clutch system for Okuma CNC turning centers enables users to float away misalignment between turret drive motors and toolholders, leading to smoother operation, better surface finishes, and longer tool life. The clutch provides a floating coupling between turret drive motor tangs and toolholders that self-compensates for any misalignment, resulting in high-precision alignment that reduces vibration and tool chatter. Okuma machine owners get a connection that is twice the size of a standard spindle, which not only provides more surface area for a strong and precise connection, but also allows for greater torque transfer and eliminates any loss of power between motors and toolholders.

The clutch also eliminates wear to turret drive motor connections by filling the gaps at the top and bottom of drive motor tangs when engaged with the toolholder, providing a complete fit all the way around the drivetrain of the motor. This eliminates backlash while delivering much quieter operation when compared to similar systems cutting the same workpiece materials at the same speeds and feeds.
