Our automatic valve seat grinder is designed for restoring valve seats for Piezo Bosch, Piezo Denso, 418, 369, and various diesel injector nozzles.
Unlike systems that rely on diamond paste, this machine uses high-quality grinding stones, making the restoration process faster, cleaner, and more precise.

The grinder operates fully automatically. The user simply selects the amount of material to remove (e.g., 10 μm), sets the grinding stone RPM, and starts the cycle with a single button. The machine grinds until the exact preset value is reached, ensuring optimal accuracy and repeatability.

Available Functions:

1. Valve Grinding

2. Valve Lapping

3. Nozzle Lapping

This advanced device is ideal for workshops that service diesel injectors and require a reliable, efficient, and high-precision solution for restoring valve seats and nozzles.
