CNC Internal Thread Grinding Machine Processing

CNC internal thread grinding machines can not only meet high-precision requirements, but also achieve efficient production processes. High-precision CNC internal thread grinding machines manufactured specifically for the measuring tool industry are mainly used to grind cylindrical and conical internal thread ring gauges.

Main uses of internal thread grinding machines

1. Applicable workpiece types-- internal thread grinding machine

CNC internal thread grinding machines are mainly used to process various types of internal thread parts, including but not limited to:

- Automotive industry: complex internal thread structures on engine blocks, transmission housings and other components.

- Aerospace: high-strength, high-precision internal threads in aircraft landing gear and hydraulic system components.

- Wind power generation: key connection parts inside large rotating equipment such as generator rotors and stators.

- Other fields: products in industries such as medical devices and precision instruments that have extremely high requirements for dimensional accuracy and surface finish.

The common feature of these application fields is the need for high processing accuracy and stability, and CNC internal thread grinding machines meet this demand.

2. Configurable measurement configuration

To ensure the quality of processing, CNC internal thread grinding machines are usually equipped with a series of precision measurement tools and technologies, such as:

- Online measurement system: Sensors integrated in the machine tool can monitor various parameters in the processing process, such as position, speed, temperature, etc. in real time, and provide timely feedback to the control system for adjustment.

- Offline measuring instrument: For some special or complex workpieces, specially designed gear measuring instruments or other special detection equipment can also be used for detailed geometric shape analysis.

- Automatic tool setting device: used to quickly and accurately set the initial position of the tool, reduce human errors, and improve work efficiency.

In addition, we also provide customized measurement solutions, and select the most suitable configuration combination according to the specific needs of customers to achieve the best processing effect.

3. Sample processing service--internal thread grinding machine

Considering that different customers may have different process requirements and technical difficulties, we have specially launched a sample processing service. This service allows potential customers to send sample materials to be processed, and our professional team will complete the preliminary processing according to the established standards, and confirm whether the final result meets expectations through strict inspection procedures. This not only helps to establish a trusting relationship, but also provides a reliable basis for subsequent batch orders.

Technical advantages of internal thread grinding machine

1. Wide processing range

- Maximum chuck rotation diameter of 600mm: This means that this model can handle cylindrical workpieces with larger diameters and is suitable for internal thread processing tasks of various specifications.

- Maximum workpiece length of 400mm: It provides sufficient installation space for internal thread processing of long shaft parts and expands the scope of application.

2. High precision and high efficiency

- Siemens high-end CNC system realizes four-axis three-linkage: It adopts internationally leading CNC technology to ensure the synchronization and coordination between the motion axes, thereby ensuring stability and precision during the processing process. At the same time, it supports complex path planning and adapts to changing processing needs.

- The headstock spindle adopts a high-precision rolling bearing structure: This design reduces friction resistance, improves rotation accuracy, and extends service life. More importantly, it lays a solid foundation for ultra-precision processing.

- Adopt diamond disc wheel dresser: It is fixed on the back side of the headstock and is used to regularly dress the grinding wheel surface to maintain its sharpness and ensure that every cut can achieve the ideal cutting effect. In addition, the choice of diamond material also reflects the pursuit of durability and consistency.

3. Flexibility and ease of use

- Friendly human-machine interface: The operation panel is simple and clear, easy to use, and even novices can quickly master basic operating skills.

- Simple and flexible programming: Supports multiple programming languages and formats, which is convenient for users to write suitable processing programs according to actual conditions.

- Convenient maintenance: The modular design makes daily maintenance simpler and more efficient, reduces downtime, and improves equipment utilization.

The difference between internal thread grinding machines and external thread grinders

Although both internal thread grinding machines and external thread grinders are machine tools for processing threads, there are significant differences between the two:

- Different processing objects: internal thread grinding machines focus on the formation of internal threads, while external thread grinders process external threads.

- Different working principles: internal thread grinding machines usually use the grinding wheel to make a spiral motion along the inner wall of the workpiece to generate threads; in contrast, external thread grinders rely more on the rotation of the workpiece and the radial feed of the grinding wheel to complete the processing.

- Different precision requirements: Since internal threads are often located in a closed space, higher requirements are placed on their dimensional accuracy and surface quality. External threads, on the other hand, can be directly observed, so a certain tolerance range is allowed in some cases.

- Differences in auxiliary devices: For example, more coolant nozzles may be installed on internal thread grinding machines to ensure adequate lubrication and cooling of the processing area; while on external thread grinders, more attention is paid to the optimized design of the chip removal system to remove chips in a timely manner.

Success story: Satisfactory experience of Turkish customers

Recently, a customer from Turkey sent us a sample, hoping to provide trial grinding services for it. After detailed communication and understanding of customer needs, we selected a suitable internal thread grinding machine and processed it strictly in accordance with the drawings and technical specifications provided by the customer. After completion, the sample was fully tested using a gear measuring instrument. The results showed that the processing accuracy far exceeded the customer's expectations, and the ground threads were very ideal, fully meeting or even exceeding the customer's quality requirements.

This successful cooperation not only enhanced the trust between the two parties, but also laid a good foundation for future long-term cooperation. The customer spoke highly of the sample processing service we provided, believing that this is a very valuable process because it not only verifies our technical strength, but also saves customers a lot of time and cost.

Whether facing demanding processing challenges or diverse market demands, we are always committed to providing customers with high-quality products and services. In the future, we will continue to uphold the spirit of innovation, constantly explore new technologies and new methods, and strive to drive the industry forward.
