DESCRIPTION
The operation of the PEG 175 is based on the principle of planetary rotation of the abrasive wheel, while maintaining the correct alignment of the system thanks to the combination of three grinding movements:
- Rotational movement
- Orbital movement
- Pendulum movement
The PEG 175 is a valve seat grinding machine built with the utmost technical rigour in all its components.
Each component of the PEG 175 is manufactured according to the highest quality standards, ensuring maximum precision in the coupling of the moving parts.
Parts such as the grinding wheel spindle, the eccentric shaft and the pilot pin undergo precision grinding operations that guarantee an excellent finish.
The rotating parts are carefully balanced and preloaded in order to prevent axial and radial play that may occur during bearing rotation.
Inside the upper part of the PEG 175 are worm gears, while on the outside there is a micrometric feed handwheel.
The component assembly stage concludes with a thorough inspection and rigorous final testing to ensure compliance with the precision, concentricity and symmetry requirements for which the PEG 175 valve seat grinding machine was designed.
The PEG 175 valve seat grinding machine is available in Standard and Variomatic versions, which differ in the composition of the accessory set supplied with the machine and in the variable-speed drive for the grinding wheel spindle, which is included in the Variomatic version.
Both versions are supplied with a complete set of accessories, including self-centring pilots, grinding wheels of various diameters and a grinding wheel dressing tool.
This allows a wide range of engines to be machined, thus meeting the needs of every operator.
