RV516 – Engine Valve Grinding Machine
The RV516 valve grinding machine is an advanced and precise engine valve grinder, ideal for engine rebuilding specialists.
The RV516 valve refacer is an engine valve grinding machine that, thanks to its advanced technical solutions, is one of the most precise and effective solutions currently available on the market for engine repair professionals.
The main feature of this machine is its centerless system, which allows the valve to rotate on its stem.
This technology ensures perfect concentricity between the valve head and the stem itself, with outstanding accuracy to within 0.01 mm.
This level of precision is essential to ensure maximum efficiency in grinding operations.
In addition, the centerless system makes it possible to work on valves with stem diameters ranging from Ø 4÷16 mm, eliminating the need to change valve clamps or mandrels each time.
The valve is dragged by three motorized rollers, with the top roller tilted to automatically drag the valve toward the adjustable limit switch.
This unique feature ensures that all valves are machined to the same length, eliminating any operator error in bringing the valve close to the grinding wheel.
This inevitably leads to consistent, high-quality results at all stages of the process.
The RV516 valve grinder is a state-of-the-art engine valve reconditioning machine whose precision, versatility and centerless design make it an ideal choice for shops of all sizes, offering high levels of efficiency and productivity.
