Product Description
Advanced CNC control system can accurately control the feed, speed and position of the grinding wheel to achieve micron-level control of parameters such as work piece bore diameter, roundness, co-axiality, etc., to meet the manufacturing needs of high-precision parts. Applicable to all kinds of steel, cast iron, non-ferrous metal materials made of shafts, bushings, discs and other parts of the inner hole precision grinding, including but not limited to cylindrical holes, tapered holes, blind holes, step holes, etc., are widely used in automotive parts, bearing industry, hydraulic components, aerospace parts and other fields.
Equipped with auto-programming and auto-compensation functions, the machine can flexibly adapt to the grinding tasks of various complex bore contours and automatically complete the grinding cycle according to the pre-set procedures, which significantly improves the production efficiency. Meanwhile, it is also equipped with an online inspection system to monitor the dimensional changes during the grinding process in real time to ensure the processing quality.
The design of the fully enclosed shield not only guarantees the safety and cleanliness of the working environment, but also effectively reduces the impact of vibration, dust and other factors on the grinding accuracy, enabling the machine tool to maintain long-term stable and reliable operation under the harsh working environment. Modular configuration and Customisation are carried out according to different process requirements of users, such as cooling system, automatic loading and unloading device, automatic measuring system, etc., to meet diversified production requirements.
