Product details




To ensure accurate cutting of the grinding wheel, smooth surface and correct geometric shape of the components, it is necessary to prevent vibration during the grinding process.

Vibration occurs during the grinding process, mainly due to the imbalance of the grinding wheel. The common reason is the unevenness of the grinding wheel itself, that is, the wheel package
Containing a large number of unevenly distributed particles, resulting in an internal imbalance in the grinding wheel. The installation of the grinding wheel is eccentric, the width of the grinding wheel is inconsistent, and the shaft is unbalanced,

Factors such as the suction of coolant into the grinding wheel may also exacerbate the imbalance of the grinding wheel. Taking into account all these factors, even the carefully established initial

The initial equilibrium will not be maintained for a long time. In addition, due to wear and dressing, the rotational dynamics of the grinding wheel are constantly changing.

Due to these reasons, people have long recognized that the dynamic balance of grinding wheels is an important link in the production process.
SBSThe balance system is designed specifically to assist grinder operators in achieving dynamic balance, taking into account the following objectives:
Easy to operate
Easy to install
high-precision



The SBS internal, "spindle internal" or "spindle type" automatic balancer is designed to be installed in the hole inside the grinder spindle. Integrated into the spindle, it can achieve mechanical optimization and save space.

The balance head consists of two electric motors, a gearbox, and calibration weights. Spindle holes ranging from 28mm to 175mm can be used.

Contact and non-contact transmissions with front-end and back-end configurations are options, providing operating speeds of 300-30000 rpm.


The system is a controller using SBS SB-5500 modular controller, which is used for grinding gap touch detection and collision prevention. The sound emission monitoring can be integrated into the flat head to achieve good grinding process control.

Installing SBS internal automatic balancer can eliminate process changes caused by grinding wheels and provide:

*Reduce trembling and wear and tear
*Improve the geometric shape of parts; Roundness, runout, and wear*
* Improve surface smoothness*
*delay
Long wheel and dressing table lifespan*
*Extend spindle life*
*Higher cutting speed and productivity*
*Save time*

The SBS Internal, 'In-Spindle' or 'Spindle Type' automatic balancer is designed to be mounted into a bore within the grinding machine spindle. Integrating into the spindle provides mechanical optimisation and space saving.

The Balance Head contains two electric motors, gearboxes & correction weights. Spindle bores ranging from 28mm - 175mm can be utilised. Contact & non-contact transmission in front & rear side configurations are options, providing operating speeds from 300 - 30,000rpm.

The system is controller using the SBS SB-5500 modular controller, and acoustic emission monitoring for grinding gap touch detection and crash prevention can be integrated into the balance head for optimum grinding process control.

Installing an SBS Internal automatic balancer removes variation in the process caused by the grinding wheel, and can provide:

*Reduction in chatter & grinding burn
*Improved part geometry; roundness, run-out & lobing
*Improved surface finish
*Increase in wheel & dresser life
*Extended spindle life
*Higher cutting speeds & productivity
*Time saving
