Characteristics and advantages
High precision:
The V4 series guide rail uses a precise V-shaped raceway design to ensure extremely high positioning accuracy and repeated positioning accuracy. This design helps to reduce the error and improve the machining accuracy and measurement accuracy of the equipment.
High rigidity:
The cross-arranged cylindrical roller design enables the guide system to withstand loads from all directions with excellent rigidity and stability. This design helps to reduce vibration and deformation and improve the operational stability and reliability of the equipment.
Low friction resistance:
The rolling friction resistance is small, the stability is good, the starting friction is small, the following performance is good. This helps to reduce energy consumption, improve the operating efficiency of the equipment, and reduce wear and heat generation.
High speed:
Due to the low friction resistance and reasonable design, the V4 series guide can support high-speed movement and meet the needs of high-speed equipment.
Long life:
The structure design is reasonable, the installation is convenient, and the mechanical energy consumption is small. These features help extend the service life of the rail system and reduce maintenance costs.
Multiple specifications available:
The V4 series guides are available in a variety of specifications and sizes to meet the needs of different equipment and application scenarios. Users can choose the right specifications and sizes according to the actual needs to achieve the best performance and economic benefits.
Technical parameters (Example)
- Dimension parameter
Guide rail model: The V4 series contains multiple models, such as V4-80, V4-100, V4-120, V4-160, etc., and different models of guide rail are different in size.
Specific dimensional parameters such as combination height, monorail width, monorail height, mounting hole, countersink hole width, countersink hole height, hole distance, and top wire length also vary with different models. For example, the JBV4 model may have specific parameters such as combination height, monorail width and height (specific values are subject to the manufacturer's information).
- Precision parameter
Positioning accuracy: V4 series high precision cross rails are known for high precision, which can ensure the accuracy of equipment operation. The specific positioning accuracy value should refer to the official information provided by the manufacturer.
Repeated positioning accuracy: The V4 series guides are able to maintain high accuracy consistency during multiple positioning processes, which is particularly important for applications requiring frequent positioning and repeated machining.
- Carrying capacity
V4 series guides can withstand large axial loads, depending on the model, material and structural design of the guide.
Some models may also have some radial load capacity, but this parameter may vary from model to model.
- Athletic performance
Maximum speed: The V4 series guide rail supports a higher maximum operating speed, which can meet the needs of high-speed motion control. The specific value depends on the type of guide rail and the application environment.
Acceleration (if provided) : Some manufacturers may provide technical parameters on the acceleration of the rail to evaluate the performance of the rail during rapid start and stop.
- Material and hardness
Guide material: V4 series guides are usually made of high-hardness materials, such as high-carbon chromium bearing steel (GCr15), to ensure the wear resistance and service life of the guide.
Hardness: The hardness value of the guide material is high, such as HRC58-62, which helps to improve the bearing capacity and wear resistance of the guide rail.
- Lubrication and maintenance
Lubrication method: V4 series guides may adopt different lubrication methods such as grease lubrication, oil lubrication or self-lubrication to reduce friction resistance and wear. The specific type of lubrication depends on the manufacturer's design and customer needs.
Maintenance requirements: Manufacturers usually provide detailed maintenance manuals and guidelines, including lubrication cycles, cleaning methods, and recommendations for replacement parts.
Application field
The V4 series of high precision cross rails are widely used in many fields, including but not limited to:
Precision machine tools: such as worktables, sliding plates, measuring machines, CNC machine tools, etc., to ensure the accurate operation and processing accuracy of the equipment.
Automation equipment: such as automation equipment, OA machines and their peripheral machines, measuring equipment, printing plate opening machine, etc., to achieve high precision and high speed motion control.
Optical tester and optical bench: In these devices, the cross rail ensures that the optical tester reaches the exact position and improves the accuracy of the test data.
Medical equipment: such as CT examination bed, X-ray machine, etc., medical equipment requiring high precision and stability is also often used cross-rail.
Summary
V4 series of high precision cross guide rails play an important role in many fields with its high precision, high rigidity, low friction resistance and long life. With the continuous development of technology and the expansion of application fields, the V4 series guide rail is expected to play a greater role in the future.
