QBM-301-HMI online grinding wheel balancing instrument

Precision grinding machine online balance inch color HMI human-machine interface resistance touch screen prolongs the life of the grinding wheel and spindle angle indication balance is simpler, and after sand repair or replacement, it can be directly balanced online grinding quality monitoring alarm grinder collision real-time protection reduces grinding wheel installation time.

Product Features

Precision grinding machine online balancing

7-inch color HMI human-machine interface

Resistive touch screen

Extend the lifespan of grinding wheels and spindles

Angle indication balance is simpler

Balance directly after sand repair or replacement

Online grinding quality monitoring alarm

Instant protection for grinding machine collision

Reduce the installation time of grinding wheels

Unbalanced angle display - The built-in DSP processor automatically measures and converts the angles of the three balance blocks, and can quickly complete the balance correction work according to the angle guidance

Relative imbalance phase angle indication - balance residual correction will automatically indicate the relative angle and move the balance block slightly to improve the balance effect

High sensitivity industrial grade acceleration gauge - Industrial grade unbalance sensor enables the balancer to more accurately measure the unbalance of the grinding wheel, and balance correction has better reliability

Balance accuracy can reach 0.01um - with a built-in modern DSP processor, the balance can reach 0.01um (p-p)

Grinding machine collision protection - immediate shutdown protection at the moment of collision to ensure that the grinding wheel/workpiece/spindle will not cause serious damage

DI/DO digital PLC interface - a communication channel can be established between PLC and QBM301 through the digital DIO interface

Touch screen, intuitive operation - resistive touch panel, can also be operated with gloves

Graphic interface/quick function keys - commonly used quick function keys for more convenient operation/measurement

IP65 Waterproof (Oil) Design - Industrial Grade Waterproof (Oil) Design, Suitable for Indoor and Outdoor Use

Shortcut Menu - Simple and Clear Menu Structure, Quickly Find Functions

Unbalance Adjustment Angle - Adjust the position of the unbalance block according to the displayed value on the screen, which can easily complete the balancing work

Grinding Quality Monitoring Trend Chart - Grinding quality can be monitored by vibration sensors

Excessive vibration alarm - ensuring the quality of the ground workpiece by setting the upper and lower limits of vibration

Simultaneous display of three vibration units - unbalanced vibration displacement display, total vibration displacement display, total acceleration display

The importance of dynamic balance correction on the grinding wheel line

Significantly improve the surface roughness, flatness, parallelism, roundness, cylindricity, straightness, and dimensional tolerances of the ground workpiece

It can reduce quality abnormalities such as burns, cracks, and processing deterioration of grinding wheels and extend the service life of workpieces

Reduce low-frequency working noise during processing and extend the lifespan of grinding wheels and dressing devices

Improve grinding accuracy, stability, and batch consistency (CPK value)

Ensure the service life of the grinder spindle and bearings, extend the maintenance interval of the grinder, and reduce the maintenance cost of the grinder and grinding wheel
