Thanks to the technical solutions adopted, the RV 516 valve grinding machine is one of the most precise and fastest machines on the market today.
The centerless system, by turning the valve on its stem, guarantees perfect concentricity between the valve head and the stem itself (within 0.01 mm), and allows a range of use in valves with stems from 4 to 16 mm without the need to replace collet or mandrels.
The valve is driven by three motorized rollers. Its upper part is inclined to automatically drag the valve towards an adjustable limit switch. This offers the advantage of having all the valves of the same length and avoiding a manual approach of the valve to the grinding wheel.
In addition, the control lever has a dual function of bringing the valve closer to the grinding wheel during grinding and lifting the upper drive roll to allow replacement of the machined valve without shutting down the engine.
The machine is completed with a grinding device for grinding wheels with:
- Micrometric regulation
- Efficient cooling system with removable pump
- Sedimentation tank.
