Calibrating and Grinding Machine

The QGM Thickness Calibration and Grinding Machine is a precision finishing solution designed for high-quality concrete products. Integrating back-surface thickness calibration, multi-stage front-surface grinding, and optional polishing, the system is suitable for further processing concrete curbstones, paving stones, concrete slabs, and other precast concrete products.
Rating: 5.0
(Rating Count: 1)

The thickness calibration unit features a dual-head design that combines cutting and finishing in a single pass. The cutting head removes excess material to achieve consistent product thickness, while the finishing head smooths the back surface, reducing rough pressing marks and waviness. Large-diameter grinding discs help minimize wave-like surface defects and maintain high flatness across the entire working width.

After back-surface calibration, products can be rotated 180° by an automatic turning device before entering the front-surface grinding process. Multiple processing stations progressively grind the product from rough grinding to fine grinding, achieving the required final thickness and surface finish. An optional polishing module is available for applications requiring superior surface quality.

With flexible processing configurations and integrated functions such as automatic turning, contact pressure control, human-machine interface (HMI), and recipe management, the system provides an efficient and adaptable finishing solution for concrete product manufacturers.

Key Advantages

1. Dual-Head Calibration in One Pass

Combines cutting and finishing heads to calibrate product thickness and smooth the back surface in a single pass, reducing pressing marks and surface irregularities.

2. Large-Diameter Grinding Discs

Minimizes wave-like surface defects and ensures high surface flatness across the entire working width.

3. Automatic Turning for Continuous Processing

An automatic turning device rotates products 180°, connecting back-surface calibration with front-surface grinding for improved processing efficiency.

4. Multi-Stage Grinding for Flexible Finishing

Supports rough grinding, fine grinding, and optional polishing to achieve different thicknesses and surface finishes according to product requirements.

5. Flexible Control and Operation

Equipped with contact pressure controllers and an independent HMI, the system supports product recipe storage and retrieval, as well as both dry and wet processing modes.
