PEG FM1 Portable Manual Valve Seat Cutting Machine
PEG FM1 is a portable manual boring machine for cutting engine valve seats.
DESCRIPTION
The PEG FM1 is a portable manual engine valve seat milling machine manufactured by PEG, a brand recognized for the quality of its products. This machine, designed and manufactured in Italy, is an excellent solution for engine valve seat machining due to its precision, versatility, and ease of use.
General Description
The PEG FM1 is a compact manual boring machine designed to work on valve seats with diameters between Ø 16 and 65 mm and valve seat rings between Ø 28 and 70 mm. The machine can be upgraded with an external motorized unit that allows the speed to vary between 30 and 100 RPM.
Design and Functionality
The PEG FM1 consists of a boring body with variable inclination and an electromagnetic clamping base that ensures secure attachment to the flat surface of the cylinder head engine. The machining system uses 3-angle shaped inserts, allowing it to:
- Restore the edges of the valve seat
- Remove the valve seat
- Enlarge the valve seat ring housing
The centering of the spindle on the centering pilot and the fixing of the machine are simplified by the electromagnetic support. Machining is performed manually with a hand crank, but can be automated with an optional variable speed electric motor drive.
Precision and Reliability
The PEG FM1 is built with high-quality materials to ensure high precision in valve seat reconditioning operations. Micrometric adjustments allow extremely accurate results, while the machine’s robustness and reliability are confirmed by numerous satisfied customers and the ready availability of replacement accessories.
Versatility and Practicality
The PEG FM1 is extremely versatile thanks to the wide range of accessories and customizations available. Standard steel or carbide centering pilots can be used for smaller sizes. The included portable case makes it easy to transport the machine, making it ideal for use in boatyards, shipyards, or any situation where it is not possible to remove the engine from the vehicle.
