Addressing Production Bottlenecks Automatic Polishing Machine in Multi-Spec

Ledrobit Machinery Co., Ltd. remains focused on the practical production pain points of stone processing enterprises, striving to solve efficiency losses in multi-variety, small-batch production through digital means.

In traditional stone polishing workshops, processing stones of different thicknesses or specifications often means frequent downtime for manual adjustments. If stone slabs with thickness variations ranging from a few millimeters to several centimeters are placed on a traditional polisher simultaneously, the lack of mechanical rigidity or height-adaptive functions often leads to under-polishing of thin slabs, over-grinding of thick ones, or even machine jams and tool damage. This "thickness conflict" forces factories to categorize and process stones in strict batches, greatly limiting production line throughput and delivery flexibility.

To overcome the bottleneck of mixed processing, Ledrobit developed a CNC vision polishing system with thickness adaptation capabilities. Its core principle consists of two parts: first, the vision scanning system automatically detects the distribution and contours of all workpieces on the table before processing begins; second, the CNC system adjusts the Z-axis height and pressure of the polishing head in real-time based on the detected data. Through high-sensitivity floating control technology, the head automatically adjusts its downward pressure according to the actual thickness of each stone, ensuring that both 20mm thin slabs and thick monuments of several hundred millimeters receive perfectly consistent surface gloss within the same processing cycle.

High operational stability relies on hard-core technical parameters. Below is the core technical specification table for this equipment:

In terms of mechanical design, the Dual Y-Axis drive system is key to ensuring mixed processing accuracy. When handling heavy workpieces offset to one side of the table, the synchronized dual-side drive effectively eliminates torsional stress on the gantry, ensuring the polishing trajectory does not suffer from physical deviation within the 3200x1500mm range. Additionally, the 14kw total power configuration paired with a 7.5kw frequency-controlled main motor provides the system with powerful dynamic response capabilities, allowing it to quickly adjust head speed and pressure during the transition between different thicknesses, thereby ensuring production continuity and equipment reliability.

For factories looking to enhance processing flexibility, we recommend leveraging the equipment's 600mm maximum processing height advantage to mix workpieces of different thicknesses, such as standard tiles and heavy curbstones. Since the vision system supports automatic recognition and skip-grinding functions, operators only need to perform one material layout, and the equipment will automatically recognize and complete the varied processing tasks. This not only reduces forklift transfers but also significantly lowers waiting times caused by batch processing, making it the best technical solution for frequent switching of small-to-medium batch orders.

By introducing vision compensation and an enhanced dual-axis drive, we have successfully elevated stone polishing from single-spec production to a new level of intelligent mixed production. This is not just a technological leap but a liberation of productivity. Ledrobit Machinery Co., Ltd. will continue to provide innovative solutions to help you achieve higher efficiency and value delivery in a changing global market.
