Do you want your rotary axis to:
- Run at much faster speeds?
- Position more accurately?
- Repeat tolerances for a much longer period?
- Not wear out?
- Be relatively undamaged if you have a major crash?
If you answered YES to any of the above, then let us introduce you to the Detron Barrelcam
Simply the fastest way to rotate your component accurately and around 4 to 5 times faster than a conventional rotary table.
The table will run up to 5 times faster as it does not have a conventional set of drive gears which limits a rotary table’s indexing speed. The Barrelcam runs freely on bearings and is limited only by the speed of the motor.
Running any conventional geared table at its maximum speed will cause heat, gear expansion and inevitable wear, whatever material it is made from. Barrelcam technology of rolling surfaces avoids those issues completely
This innovative barrel cam design uses dual lead high load technology driving a minimum of 20 high precision roller bearings. If you have a crash, you may break teeth on a conventional table gear or wormshaft, making it a very expensive repair, with your machine out of action, our device will simply roll out of the way in any major collision with crash avoidance technology.
The barrel cam is ideally suited to fast component positioning to repeating angles with no wear and no backlash
If you have components that you make in repeating quantity a geared table will wear locally at these repeating positions over time, reducing positional accuracy at those points. Barrelcam uses a bearing drive system, there are no wear and no repeatability issues as the shaft and rollers never all end up in the same place twice.
Localised wear on a gear set cannot be adjusted out, so requires careful management of fixture positions, the Barrelcam fixture can remain on the unit where you first position it.
Geared tables have low efficiency which means that the power from the motor is greatly reduced through the gear chain by the time it gets to the component (usual torque efficiency of a geared table is around 28% of the input torque), this means turning torque for contouring is small compared to the Barrelcam system which has a much higher drive efficiency rating (around 80%).
In every respect Barrelcam is the future of rotary table design and is only available from DETRON.
