When high volumes and extreme precision are required, double-sided fine grinding with the Planet V4 and V7 is the ideal solution.

The Planet V series machines are designed for maximum precision and efficiency in series production. Innovative features such as the patented tilting navigation for fast grinding gap setup, integrated tool change assistance, and an intelligent dressing system ensure user-friendly and process-safe operation.

Thanks to an extremely rigid machine base, the highest throughput and tightest tolerances can be achieved reliably in just one pass – ideal for watch parts and other precision mechanical components made of steel, sintered metal, non-ferrous metals, plastics, ceramics, or glass.

For maximum productivity, the Planet V4 and V7 can be seamlessly integrated into automated production lines. Automated loading, as well as upstream and downstream processes like cleaning, brushing, or measuring, can be customized and smoothly incorporated.

Typical Components

• Precision parts such as piston rings, spacers, barquettes, etc.
• Stamped and forged parts
• Flat-parallel components made of steel, carbon, brass, etc.

Advantages

• Maximum productivity with simultaneous processing of both sides
• Highest material removal rates at shortest cycle times
• Rugged technology for continuous operation in mass production
