Intelligent processing technology
Depah Precision introduces advanced intelligent processing system to realize intelligent control of the processing process through real-time collection and analysis of processing data. When the screw rotor is processed, the system can automatically adjust the key parameters such as the spindle speed and feed rate according to the preset process parameters and the real-time monitoring of the processing state to ensure that the processing process is always in the best state. In the process of grinding the tooth surface, the system can dynamically adjust the feed speed of the grinding wheel according to the real-time grinding of the tooth surface to ensure the machining accuracy and surface quality of the tooth surface.
High precision grinding process
Optimization of Grinding Parameters Based on Know - How
After years of technical accumulation and practical exploration, Depa Precision has mastered a set of unique grinding parameter optimization methods. When grinding the screw rotor, according to the material characteristics of the rotor, the requirements of the type line and the machining accuracy standard, the particle size, hardness, binder and other parameters of the grinding wheel are accurately selected, and the grinding speed, feed rate and grinding depth are reasonably adjusted. Parameters, so as to achieve efficient and high-precision grinding. For the alloy material rotor with high hardness, the grinding wheel with appropriate particle size and hardness is selected, and the grinding depth and appropriate feed are adopted, which can not only ensure the grinding efficiency, but also ensure the machining accuracy.
Advanced grinding wheel dressing technology
The dressing accuracy of the grinding wheel directly affects the machining accuracy of the screw rotor. Depa Precision adopts advanced grinding wheel dressing technology, such as online electrolytic dressing (ELID) technology, which can dress the grinding wheel in real time during the grinding process to ensure that the grinding wheel always maintains good grinding performance and precise profile. Through ELID technology, the dressing accuracy of the grinding wheel can be controlled at the micron level, which effectively improves the machining accuracy and surface quality of the screw rotor tooth surface.
Fine preparation before processing
Strict screening of raw materials and fixtures
Before processing, the raw materials are strictly inspected and screened to ensure that their material characteristics meet the processing requirements. Establish long-term cooperation with high-quality suppliers to ensure the quality of raw materials from the source. At the same time, the fixture is fully inspected and debugged to ensure that its accuracy and stability meet the processing requirements. When machining high-precision screw rotors, high-precision ground centers and chucks are used to ensure the positioning accuracy of the rotor during processing.
Customized design of processing technology scheme
According to the specific requirements of the screw rotor, combined with the characteristics of the equipment and processing experience, a personalized processing process plan is formulated.
