Working Principle:
Sino Zhonglun Tech Group Co., Ltd. is an outer ring raceway grinding machine exporter. The outer ring raceway grinding machine operates on the principle of abrasive cutting, where a grinding wheel, composed of abrasive grains held together by a bond, removes material from the workpiece. The process involves the following steps:
1. Grinding Wheel Engagement:
The machine uses a grinding wheel that rotates at high speed to engage with the outer ring of the bearing. The abrasive particles on the wheel's surface cut into the metal, removing material and shaping the raceway.
2. Cylindrical Grinding Process:
The workpiece, which is the outer ring of the bearing, is held securely between centers or in a chuck. It rotates while the grinding wheel, which can be either cylindrical or conical, moves along the length of the workpiece to grind the raceway to the desired dimensions.
3. Precision Control Systems:
Modern outer ring raceway grinding machines are equipped with advanced control systems that allow for precise control of the grinding process. These systems ensure that the wheel's position, speed, and feed rate are accurately controlled to achieve the required precision.
Technical Features:
The technical features of an outer ring raceway grinding machine that contribute to its high-precision capabilities include:
1. High Rigidity and Compact Design:
The machine's compact design and strong rigidity ensure stability during the grinding process, which is essential for maintaining precision. The robust construction minimizes vibrations and deflections that could affect the accuracy of the grind.
2. Advanced Control Systems:
Siemens 828D NC, ball screw, and optical deletion control systems are used to achieve a resolution of 0.1μm. These systems are adjustable, allowing operators to fine-tune the grinding process for different materials and specifications.
3. Diamond Disc Rotary Dressing:
The grinding wheel is dressed using a diamond disc, which ensures a perfect groove curvature and shape. This rotary dressing method is crucial for maintaining the accuracy and consistency of the grinding process.
4. Optimized Software:
The machine's software is optimized for stability and reliability, resulting in a low failure rate. This software controls the machine's movements, ensuring that the grinding process is smooth and consistent.
5. Self-Diagnostic System:
A self-diagnostic system helps operators identify and solve problems by providing text alarms and prompts. This feature is invaluable for maintaining the machine's performance and for preventive maintenance.
6. User Access Control:
Users can set passwords to protect the machine's parameters, ensuring process discipline and preventing unauthorized changes that could affect the grinding process.
