Practical Solutions For Polishing Wheel Wear Compensation in Stone Polishing Machine

In Stone polishing machine operations, quickly and accurately compensating for polishing wheel wear on products of different materials and shapes is a core challenge for operators. Currently, the most commonly used methods for compensating polishing wheel wear in Stone polishing machines include:

1. Manual Handwheel Compensation Method

Operators manually rotate the handwheel to adjust the vertical displacement of the polishing wheel, changing its contact pressure with the product. Advantages include simple structure, low cost, and convenient maintenance, suitable for small to medium batch production and low-precision requirements. Disadvantages include reliance on operator experience, susceptibility to compensation deviations, and difficulty in ensuring batch polishing consistency.

2. Stepper Motor Compensation Method

Automatic compensation time intervals are preset according to the polishing wheel wear pattern. After receiving periodic electrical signals, the stepper motor rotates at a preset number of revolutions to compensate for wear. This method does not require experienced personnel, reducing labor costs and skill barriers, and is suitable for standardized batch production. However, the compensation accuracy is affected by the time interval and is difficult to adapt to conditions with large fluctuations in power consumption rates.

3. Servo Motor Compensation Method

Using a constant operating current of the polishing wheel as the control benchmark, when wear of the polishing wheel leads to reduced pressure and current, the control system triggers servo motor compensation. Compensation automatically stops once the current and pressure return to preset values. This method offers high precision, fast response, and adaptability to wear variations, making it suitable for high-precision and complex machining scenarios.

4. Hydraulic Motor Compensation Method

Maintaining constant contact pressure between the polishing wheel and the product, this method relies on the strong and stable driving force of the hydraulic system. It is suitable for conditions requiring high cutting forces (such as polishing high-hardness materials and products with thick oxide layers), providing stable compensation during high-intensity operations and reducing polishing defects caused by pressure fluctuations.
