1. Introduction
With the rapid development of global construction, automobile, home appliance and emerging energy industries, the demand for flat glass products continues to grow, and the requirements for cutting accuracy, shape complexity, production efficiency and processing safety are increasingly stringent. Traditional manual glass cutting and semi-automatic cutting equipment have been difficult to meet the needs of large-scale, high-precision and diversified production due to low efficiency, large error, high labor intensity and high breakage rate. As an advanced special equipment for glass processing, the CNC glass cutting table (tilting type) combines computer numerical control technology, precision mechanical transmission technology and pneumatic auxiliary technology, which not only realizes the automatic and precise cutting of glass sheets of different sizes and thicknesses, but also completes the safe conversion between vertical and horizontal positions of glass through the tilting mechanism, which greatly reduces the risk of glass damage and personnel injury in the handling process.
The emergence of tilting CNC glass cutting tables has promoted the transformation of the glass cutting process from "manual handling + horizontal cutting" to "automatic loading + CNC cutting + tilting blanking", which is a major technological innovation in the glass deep-processing industry. Compared with non-tilting fixed cutting tables, it has obvious advantages in space utilization, operation convenience, product yield and production continuity, and has become an indispensable key equipment in modern glass processing production lines.
2. Basic Definition and Classification of CNC Glass Cutting Table (Tilting Type)
2.1 Basic Definition
CNC glass cutting table (tilting type) is a special numerical control processing equipment that takes flat glass as the processing object, adopts computer programming to control the cutting path and cutting parameters, and is equipped with a mechanical tilting mechanism that can realize the angle adjustment of the workbench. It can stably switch the glass sheet between the vertical loading state, the horizontal cutting state and the tilting unloading state, and complete the whole process of automatic feeding, precise positioning, CNC cutting, auxiliary breaking and safe discharging under the coordination of pneumatic, electrical and mechanical systems.
2.2 Main Classification
According to different classification criteria, tilting CNC glass cutting tables can be divided into multiple categories:
- According to the control accuracy, it can be divided into standard precision type (cutting accuracy ±0.25mm/m) and high precision type (cutting accuracy ≤±0.15mm/m), which are suitable for conventional glass processing and high-end precision glass processing respectively.
- According to the tilting drive mode, it can be divided into mechanical chain drive type and electric servo drive type. The mechanical chain drive type has the advantages of simple structure and low maintenance cost, and the tilting time can be controlled within 20 seconds; the electric servo drive type has higher motion accuracy and stability, and is suitable for high-end production lines with strict requirements for position control.
- According to the processing scale, it can be divided into small and medium-sized type (processing glass size ≤2440mm×1830mm) and large-scale type (processing glass size ≥3660mm×2440mm), which meet the production needs of small and medium-sized glass workshops and large-scale glass processing bases respectively.
- According to the functional integration, it can be divided into single cutting function type and multi-functional integrated type (integrating automatic loading, air flotation conveying, edge deletion, automatic labeling and other functions), which is suitable for single process processing and full-automatic production line matching.
3. Structural Composition of CNC Glass Cutting Table (Tilting Type)
The tilting CNC glass cutting table is a complex system integrating machinery, electricity, pneumatics and numerical control, and its core structure mainly includes the following parts:
3.1 Frame and Workbench System
The frame is the load-bearing foundation of the whole equipment, usually made of high-strength steel plate welded and tempered, with high rigidity and stability, which can effectively avoid vibration and deformation during the cutting process and ensure cutting accuracy. The workbench is the carrier of glass placement and cutting operation, and the surface is covered with high-density anti-static and wear-resistant felt, which can protect the glass surface from scratches and reduce the friction between the glass and the workbench. Most tilting cutting tables are equipped with an air flotation system on the workbench surface, which generates a uniform air cushion through high-pressure fans, so that the glass sheet is in a suspended state, facilitating the movement and positioning of the glass and reducing the breakage rate caused by friction.
3.2 Tilting Mechanism
The tilting mechanism is the core component that distinguishes the tilting cutting table from the ordinary cutting table, mainly composed of drive motor, transmission chain (or servo screw), support shaft, limit device and balance cylinder. It can drive the workbench to rotate stably within the angle range of 0° (horizontal) to 85°-90° (vertical) under the control of the numerical control system. The balanced tilting design ensures that the glass sheet does not shift or fall during the angle conversion process, and realizes the smooth transition from vertical loading to horizontal cutting and then to tilting unloading. Compared with the traditional hydraulic tilting system, the current mainstream mechanical and electric tilting mechanisms have the advantages of zero maintenance, fast response and stable operation, and are more in line with the needs of industrial continuous production.
3.3 CNC Cutting System
The CNC cutting system is the "brain" of the equipment, including industrial control computer, motion control card, servo motor, linear guide rail, cutting head and other components. The cutting head is equipped with a precision cutting wheel (diamond or carbide material), which can realize 360° arbitrary rotation to adapt to the cutting of straight lines, arcs, irregular graphics and other complex shapes. The numerical control system can import CAD drawing files, automatically optimize the layout, control the cutting speed, cutting pressure and knife lifting height in real time, and ensure that the cutting trace is accurate and the cutting edge is smooth. At the same time, the automatic lubrication system is matched with the cutting head to reduce the wear of the cutting wheel and prolong the service life.
3.4 Pneumatic Auxiliary System
The pneumatic system mainly provides power for glass adsorption, clamping and air flotation, including air compressor, air storage tank, solenoid valve, air nozzle and suction cup. The vacuum suction cup can firmly adsorb the glass sheet during the tilting process to prevent sliding; the pneumatic clamping device can fix the glass position during cutting to ensure positioning accuracy; the air flotation nozzle forms a uniform air cushion on the workbench surface, which realizes the labor-saving movement of large-size glass sheets.
3.5 Safety Protection System
To ensure the safety of equipment operation and personnel, the tilting CNC glass cutting table is equipped with a complete safety protection system, including emergency stop button, safety grating, overload protection, limit switch and fault alarm device. The safety grating can detect the entry of foreign objects in the working area and stop the equipment immediately; the limit switch controls the maximum tilting angle of the workbench to prevent overtravel damage; the fault alarm system can prompt the abnormal parameters such as motor overload, air pressure shortage and program error in real time, which is convenient for timely troubleshooting.
4. Working Principle of CNC Glass Cutting Table (Tilting Type)
The operation process of the tilting CNC glass cutting table follows the logic of "automatic loading → precision positioning → CNC cutting → tilting blanking", and the specific working principle is as follows:
4.1 Vertical Loading Stage
The numerical control system controls the tilting mechanism to lift the workbench to a nearly vertical state (about 85°). The operator or the automatic loading machine places the raw glass sheet on the vertical workbench, and the vacuum suction cup and pneumatic clamping device act simultaneously to fix the glass sheet stably without shaking. This loading method is close to the conventional glass storage and handling posture, which reduces the difficulty of glass handling and avoids the edge breakage caused by horizontal handling of large-size glass.
4.2 Horizontal Cutting Stage
After the glass is fixed, the tilting mechanism drives the workbench to slowly and stably turn to the horizontal state, and the air flotation system starts at the same time to generate an air cushion to support the glass. The operator inputs or imports the cutting graphics through the numerical control system, and the system automatically optimizes the layout to improve the glass utilization rate. Then the servo motor drives the cutting head to move along the set path along the linear guide rail, and the cutting wheel presses the glass surface with appropriate pressure to complete the scribing operation. For low-E glass, coated glass and other special varieties, the equipment can also be equipped with an edge deletion function to remove the coating layer at the cutting edge to ensure the cutting effect.
4.3 Tilting Unloading Stage
After the cutting and scribing are completed, the auxiliary breaking device acts to separate the cut glass along the scribing line. Then the tilting mechanism lifts the workbench to the vertical or inclined state again, the air flotation system and suction cup are released, and the operator can easily take out the cut glass finished products. The whole process avoids the repeated horizontal handling of glass, greatly reduces the labor intensity of workers and the breakage rate of glass, and improves the production efficiency.
5. Core Technical Characteristics and Advantages

The tilting CNC glass cutting table adopts high-precision linear guide rail and servo drive system, and the cutting accuracy can reach ±0.15mm-±0.25mm/m, which meets the processing requirements of high-precision glass products such as automotive and architectural curved glass. The cutting head with automatic pressure adjustment function can adapt to glass sheets with thickness ranging from 2mm to 25mm, ensuring that the cutting edge is smooth and free of cracks, and the subsequent grinding and polishing workload is reduced. The automatic layout function of the numerical control system can maximize the utilization rate of glass raw materials, reduce the production cost of enterprises.
5.2 High Production Efficiency and Short Processing Cycle
The integrated design of tilting loading and unloading eliminates the time-consuming process of manual glass turning and handling, and the tilting conversion time of the workbench is less than 20 seconds, which greatly shortens the auxiliary operation time. The CNC automatic cutting mode replaces manual scribing, and the cutting speed is fast and continuous, which can realize 24-hour uninterrupted operation. Compared with traditional equipment, the production efficiency can be increased by more than 50%, and it is suitable for large-batch and continuous glass processing production.
