Rotary bearing CNC drilling machineIt is a specialized CNC machine tool for high-precision drilling, tapping, and milling of large slewing bearings (also known as rotary bearings), widely used in the manufacturing of high-end equipment such as wind power, engineering machinery, port machinery, metallurgical equipment, radar turntables, and heavy robots. As the core transmission component connecting rotating and fixed parts, the slewing bearing has dozens to hundreds of high-precision mounting holes distributed on its end face or inner and outer rings. The requirements for hole position accuracy, pitch diameter consistency, and surface quality are extremely strict, and traditional processing methods are difficult to meet the requirements of high efficiency and high precision.
This drilling machine adopts a high rigidity gantry or vertical structure, equipped with a high torque servo spindle and an automatic tool changing system, which can achieve multiple processes such as drilling, reaming, countersunking, tapping, and even light milling in one clamping. The core feature is the integration of high-precision CNC rotary worktable (usually dual drive or torque motor direct drive), with a division accuracy of up to ± 5 ", combined with fully closed-loop grating feedback, ensuring that the position error of each bolt hole on the large diameter (usually 2-6 meters) circumference is controlled within 0.02 mm. The machine tool is also equipped with laser alignment, automatic alignment, and workpiece recognition system, which can adapt to the rapid replacement of different specifications of rotary bearings.
Rotary bearing CNC drilling machineIntroduction to the main features:
1、 High precision
Precise control of numerical control technology: By using a numerical control system to accurately position and control the movement of the drill bit, high-precision drilling operations can be achieved. This precise control is not only reflected in the aperture size, but also in the position and shape of the holes, greatly improving product quality.
High positioning accuracy and repeatability accuracy: The machine tool is supported and guided by a rolling guide rail pair, and driven by a precision screw pair. It has high positioning accuracy and repeatability accuracy, ensuring the stability and consistency of the machining process.
2、 High efficiency
Automated motion control: CNC drilling machines achieve automation of the machining process by programming the movement of the spindle and worktable. This automation control not only reduces the time and workload of human operation, but also improves processing speed and efficiency.
Multi functional machining capability: It can not only perform drilling machining, but also complete various processes such as reaming, overall milling, tapping, etc. This multifunctionality enables one device to complete multiple processing tasks, further improving production efficiency.
3、 Multifunctionality
Adapt to different materials and shapes: This equipment can achieve hole processing of different shapes and sizes, suitable for drilling needs of various materials. Whether it is hard metal, soft metal, alloy, plastic, fiber and other materials, efficient processing can be achieved by adjusting processing parameters and process routes.
Multiple processing technology integration: In addition to drilling, it can also integrate various processing technologies such as reaming, tapping, scraping flat surfaces, and trimming end faces. This integration enables the equipment to have higher flexibility and efficiency when processing complex parts.
4、 Flexibility
Quick adjustment of machining parameters: Due to the use of CNC technology, machining parameters and process routes can be quickly adjusted as needed. This flexibility enables the equipment to adapt to the processing needs of different products, improving production adaptability and market competitiveness.
Adapt to different production scales: Whether it is small-scale production or large-scale production, production needs can be met by adjusting processing parameters and process routes. This adaptability enables the equipment to function efficiently at various production scales.
5、 Automation
Linkage with other devices: It can be linked with other automation equipment to achieve automated operations on the production line. This automated operation not only improves production efficiency, but also reduces labor costs and safety risks.
Intelligent monitoring and fault diagnosis: Some advanced rotary bearing CNC drilling machines are also equipped with intelligent monitoring and fault diagnosis systems. These systems are able to monitor the operational status and processing quality of equipment in real-time, promptly identify and address potential issues, and ensure the stable operation and processing quality of the equipment.
6、 Structural advantages
Stable support structure: Generally, integral castings are used as the bed material, which is precision machined after secondary tempering and vibration aging treatment. This structure gives the bed body excellent dynamic and static rigidity, without deformation, and provides stable support for the machining process.
Reasonable layout of workbench: The workbench adopts a cast structure, with precision machined T-shaped grooves on the plane for clamping workpieces. At the same time, the evenly distributed design of the cutting edge also facilitates the cleaning work of the iron cutting. These designs have improved the processing efficiency and usability of the equipment.
