PULCOM AB-10
Grinding Wheel Auto Balancer
- Easy operations
- Shortest balancing time
- Built-in DSP
Grinding wheel auto-balancer advantages
Reduce more than half of normal Grinding Wheel Exchange time.
(Comparison: Fully Trained Staff: 43 mins Vs Auto-balancer: 18 mins)
Special skill is not required to achieve ideal dynamic balance condition, safely and automatically.
Improved grinding process quality by preventing vibration.
Grinding wheel exchanging time and Remaining Unbalance
Maintaning and Improving the Process Quality
PULCOM AB-10 observes vibration of grinding table, and if the vibration level becomes more than the threshold setting value, signal will be sent to NC to notify the operator that correction of balancing is needed. This system prevents production of defects caused by unbalanced grinding wheel.
High Precision Balancing
PULCOM AB-10 adopts high performance DSP (Digital Signal Processor), and the algorism is optimized by using Accretech’s (Tokyo Seimitsu’s) 3D coordinate measuring machine technology and roundness measuring machine technology. By moving weight, vibration change occurs and balance correction position can be calculated from this slight vibration change. Therefore, perfect balancing can be achieved in a short time.
Flange type balance head system
Non-contact type balance head system
Installation example
This is the most applicable head type, e.g. for cylindrical, surface, and centerless grinders.These can be installed into either grinder wheel side or pully side (when there are no interfering objects or other kinds of impediments.) Also, these are suitable for grinders with bload line-up covering balancing volumes from 400 to 7500 gcm.
Cylindrical grinder (pully side installation)
Installation
Centerless grinder (pully side installation)
Angular grinder (Grinding wheel side mounting)
Brush type balance head system
Installation example
Balance head cable for this head type is detachable. Only one controller is required to use multiple number of balance heads. (To avoid wearing of brushes, detach balance head cable and cap the connector when balancing is finished.)
This system is suitable especially for cylindrical/surface grinder in middle/large manufacturing line.
