MU1913 – PEG 8 USED VALVE SEATS GRINDING MACHINE
The used valve seats grinding machine PEG 8 is in acceptable condition.
DESCRIPTION
The PEG 8 used machine is an orbital grinder specifically designed for machining engine valve seats, with a working range of Ø 16 mm to Ø 48 mm. This compact and portable tool is critical for ensuring compression sealing in internal combustion engines, thereby improving overall engine performance.
The PEG 8 employs advanced orbital technology with a planetary system that integrates three distinct but synchronized movements on a single axis. In operation, the grinding wheel rotates on its own axis while simultaneously rotating along the orbit of the valve seat and oscillating relative to the seat plane. This configuration allows the wheel to move in a circular and inclined fashion, ensuring uniform and precise machining of the valve seats, which is essential for the proper functioning of the engine.
A special feature of the PEG 8 used grinder is its operating unit, designed to minimize errors due to part misalignment. The eccentric shaft, which passes through the main spindle, has a fixed eccentricity that ensures precise advancement along the perimeter of the valve seat. Its inclination provides the angular convergence necessary for quality grinding.
The grinding wheel rotates on itself while simultaneously orbiting the valve guide axis, creating a perfectly concentric circular orbit that optimizes grinding precision. These advanced technical features make the PEG 8 an ideal choice for those who need a reliable and precise machine for engine maintenance and repair. It offers the ability to improve engine efficiency through accurate valve seat machining.
