Achieving a flawless seal is the ultimate goal in valve performance. The JWM Model Planetary Lapping Machine is a state-of-the-art solution engineered to deliver exceptional surface finish and sealing conformity on valve discs, wedges, and seats. Leveraging a patented design with planetary motion, this machine provides a non-repetitive, uniform grinding pattern that is impossible to achieve with manual methods. The JWM Model is the ideal equipment for valve manufacturers and service workshops aiming to enhance product quality, increase production throughput, and reduce operational labor costs.
Key Features
- Advanced Planetary Motion: The core of the JWM Model is its unique grinding mechanism where workpieces both revolve around a central axis and rotate on their own. This dual motion ensures a random, cross-hatched lapping pattern, resulting in a perfectly flat, non-directional surface finish.
- Exceptional Surface Finish: The machine consistently produces a highly polished sealing surface with a roughness of $Ra \le 0.8 \mu m$, creating a mirror-like finish that significantly reduces the potential for leaks.
- High Sealing Conformity: The precision of the planetary action guarantees a sealing contact area (吻合度) of $\ge 80\%$, ensuring a tight and reliable seal under pressure.
- High-Efficiency Operation: Designed for ease of use and low labor intensity. A single operator can manage multiple JWM machines simultaneously, drastically increasing production efficiency and reducing costs.
- Variable Frequency Control: The integrated variable frequency drive allows for precise control over the lapping speed, enabling operators to optimize the process for different workpiece materials and grinding compounds.
- Secure Workpiece Fixturing: The lapping plate is equipped with robust positioning rings to securely hold multiple valve discs or gate valve wedges, ensuring stability and consistency throughout the grinding cycle.
