Intelligent Technological Transformation Case of Old Glass Drilling Machines

Many glass processing factories' old semi-automatic drilling machines rely on manual marking and positioning, with large positioning errors and a bulging edge rate exceeding 12%, and the single machine daily production capacity is less than 3,000 holes, with high consumable costs. A processing factory in deep processing carried out equipment transformation, adding a visual automatic positioning system, a variable frequency air pressure control system, replacing wear-resistant sintered diamond drill heads, and installing a circulating purified water cooling device. After the transformation, the equipment automatically captures the hole position, with positioning accuracy of ±0.03mm, eliminating the manual marking process; by fine-tuning the feed speed with frequency conversion, the glass bulging edge rate was reduced to within 3%, and the single machine daily production capacity was increased to 5,200 holes, with the drill head consumables cost decreasing by 42%. For high-end orders, additional laser auxiliary machines were installed to cover both regular large holes and precise micro-holes, expanding the automotive glass processing business, and the transformation investment was fully recovered within 8 months.
