OUR MACHINERY

Power honing with SynchroFine – more refinement needed?

What makes SynchroFine unique is the compact design of all units. All units are mounted on a natural granite bed for optimal thermal and vibration-damping characteristics.

The digital and directly driven tool and workpiece spindles guarantee backlash-free drive and load reversal, as there is no need for mechanical transmission elements, such as toothed belts, gears, etc.

The machine is designed as a self-loading unit (pick-up principle) and is basically equipped with integrated handling units. The components can be fed individually. From simple manual loading through automation solutions with conveyor belts to robot cells with integrated camera functions from our sister company rbc robotics, we can use a wide range of automations according to your preferences and needs.

For even more efficiency, we can equip the system with two workpiece spindles in order to reduce non-productive times to a minimum.

The digital recording of operating parameters is also standard with the SynchroFine. It can be further expanded through various modules in order to analyze process data and thus continuously optimize processes

Workpieces and machines

Models

SychroFine One spindle model

The “pick-up” design of the machine enables the simplest of automation concepts. The workpiece spindle takes on the loading and unloading function of both the workpieces and the dressing tools.

SynchroFine Two-spindle model

Even the single spindle SynchroFine achieves extremely short cycle times. With PRÄWEMA’s decades of experience in the production of machines with two or more spindles, the SynchroFine type is also used for the two-spindle PräwemaHoning®. This reduces non-productive time down to three seconds.

Innately precise SynchroFine

What makes SynchroFine unique is the compact design of all units and the innate precision.

Synchronization in precision SynchroForm

Synchronous processes are more efficient and also reduce capital expenditures for the machine fleet.

Highly efficient soft and hard machining SynchroForm-V

The vertical series of our machinery offers a platform on which main and secondary processes can be individually combined, which means that the entire gear cutting process can take place in the soft or hard state.
