Built in fully automatic dynamic balancing system
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. Given all these factors, even if carefully adjusted
Balance cannot 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
The existence of reasons has long been recognized that the dynamic balance of grinding wheels is an important link in the production process.


When the purchase cost of a fully automated system is not guaranteedThe SB-1000 control unit can also be configured to assist in manual balancing operations.
When the system is in manual balancing mode, it does not need to be turned onSBS automatic balancer.
But using a methodRPM sensor is used to detect the rotational speed (RPM) and phase of the spindle during rotation. RPM signals that are not synchronized in time with the physical position on the spindle assembly (from the motor or other sources),
Cannot fully achieve balance. An RPM sensor with a fixed trigger point must be used to determine the phase of the spindle.


The balance weight of the grinding wheel needs to be measured by the operator according to the required quantityManually remove or shift to achieve balance effect.
SB-1000 assists the operator by analyzing the current balance status of the spindle and instructing them on how to position the counterweight to achieve balance.

When to perform automatic balancing
When the grinding wheel comes into contact with the workpiece or dresser, it will cause greater vibration in the grinding machine. This is a normal phenomenon, and these levels may exceed the tolerance water
Flat, but this vibration is not related to the balance of the grinding wheel. The vibration level can be checked manually or through a hard wired interface to determine if it needs to be readjusted
Heng. This can only be done when grinding or finishing operations are not carried out(such as between processed components), can be carried out. The automatic balancing cycle should also only be performed at the same time in the process.
Otherwise, the automatic balancing cycle during grinding or finishing processes will result in even worse balancing conditions.


Select balance mode (automatic or manual)
The SB-1000 can operate in two different modes, namely automatic balancing mode and manual balancing mode.
Automatic balance mode usageSBS balancer is used to perform fully automatic balancing operations.
Manual balance mode usageRPM sensor without using SBS balancer.


SBS balance heads are all electric mechanical units, and each balance head is equipped with two motors with special gears
These units are used to locate two independent balancing blocks to adjust the imbalance.
Regardless of whether the balance head is in a stationary or rotating state, the weight of the balance weights in both balance heads can be adjusted
The adjustment of the balance block is achieved through power and data input.
In this mode, the control unit operates as a balance analyzer, guiding users on how to manually adjust the counterweight on the spindle grinding wheel to achieve balance. Press downPress and hold the Setup button for 1 second to display the balance mode selection screen.

The purpose of the anti-collision system is to avoid prolonged start-up of the machine tool, control the collision between the grinding wheel/workpiece, and control the dressing process.
Processing safety is very important in fully automated production processes.

Only controlled and optimized production processes can make products more economical and competitive.
An effective process control and analysis system must be able to adapt to the different requirements of different equipment and programs.
The key to rationalization possibilities! The key to economic principles lies in
It is always possible to find a perfect and economical solution-from an easy system for spark-in
control(GAP control) to complete system incl. Visualization for process analysis and in order to
optimize the processes.

From simple collision prevention control to a complete, complex system that includes process analysis and graphical display, one can find a solution
A plan for optimizing the economic processing program.
Safety has priority! Safety is always the top priority!
Therefore all actual unit for the control of grinding processes are fully equipped with GAP/Crash/Dress
systems (Crash control)

Therefore, all units related to grinding need to be equipped with GAP/Crash/Press systems
