The outer ring edge grinder, especially the cylindrical roller bearing outer ring edge grinder, is a key equipment in the bearing manufacturing process. The following is a detailed introduction to it:
I. Definition and Application
The outer ring edge grinder is mainly used to machine the outer ring edge of cylindrical roller bearings. Through high-precision grinding technology, it ensures that the outer ring edge of the bearing meets the design requirements. This device has a wide range of applications in the bearing manufacturing industry and is an important tool for improving the quality and performance of bearings
2. Main features
High precision: The outer ring edge grinding machine adopts advanced digital control system (such as Mitsubishi's full digital control system in Japan), which can achieve high-precision positioning and ensure the accuracy of grinding processing.
Superior surface quality: Through precise grinding technology, the surface roughness of the outer ring edge can be significantly reduced, surface defects can be minimized, and the running stability and service life of the bearing can be improved High degree of automation: Modern outer ring edge grinding machines are usually equipped with automatic loading and unloading systems, single arm robotic arms, and other automation devices, which can achieve continuous and efficient production operations Strong adaptability: able to adapt to the grinding processing requirements of the outer ring edge of cylindrical roller bearings with different specifications and materials Strong stability: Adopting precision transmission devices such as servo motors and ball screws to ensure the stability of the grinding processIII. Application Case
Taking the overall outer ring grinding process of a four row cylindrical roller bearing for a rolling mill as an example, the bearing has four rows of raceways, sealing grooves on both sides, and 5 blocking edges. Among its 10 end faces, 8 are rolling element blocking edges and 2 are sealing ring blocking edges. The overall accuracy of the bearing is P5.
. This type of bearing has multiple raceways and retaining surfaces, requiring high precision and making grinding difficult. However, by adopting improved processing techniques such as double row support, floating support, and fixed support, the processing difficulties have been successfully solved, the support rigidity has been improved, and the support instability caused by factors such as grinding wheel feed on the workpiece has been reduced. As a result, the accuracy indicators such as the perpendicularity of the raceway to the end face, the circular runout between raceways, and the diameter variation of the raceway have been significantly improvedIV. Market Situation
With the development of manufacturing industry and continuous technological innovation, the demand for outer ring edge grinding machines continues to increase.
. Currently, there are multiple manufacturers in the market offering different types of outer ring edge grinding machines, with prices varying depending on factors such as brand, model, and configuration. Some well-known manufacturers provide high-quality and high-precision outer ring edge grinding machines, which have been widely recognized by usersFifth, Selection Suggestions
When choosing an outer ring edge grinding machine, it is recommended to consider the following factors:
Processing Requirements: Choose the appropriate machine model and configuration according to your own processing needs.
Brand reputation: Choose well-known brands and reputable manufacturers to ensure the quality and after-sales service of machine tools Price factor: Considering the price factor while ensuring quality, choose machine tools with higher cost-effectivenessTechnical support: Understand whether the manufacturer provides technical support and training services so that any problems encountered during use can be resolved in a timely manner.
In summary, the outer ring edge grinder plays an important role in the bearing manufacturing industry. When choosing, factors such as processing needs, brand reputation, price, and technical support should be fully considered to ensure the selection of suitable machine tools
