Valve Seat and Guide Milling Machine FSG-1500

The valve seat and guide milling machine is used to precisely machine valve seats and guides in engine cylinder heads. It corrects defects like wear, scratches or warping of these parts, ensuring perfect valve sealing. The FSG-1500 works with seats from 0.7 to 2.4 inches (Ø18 to 60mm), servicing car, motorcycle and commercial vehicle engines. It's essential equipment for machine shops that provide complete cylinder head services.

The FSG-1500 has capacity to mill seats from 0.7 to 2.4 inches (Ø18 to 60mm), with variable speed 0 to 350rpm. The tool spindle has 7.9 inches (200mm) stroke and ISO 30 taper, ±15° inclination. Table supports cylinder heads up to 59 inches (1500mm) without fixture (47 inches/1200mm with fixture). 1hp motor, 220V three-phase. Machine dimensions: 6.2 x 2.6 x 7.2 ft (1.9 x 0.8 x 2.2m), approximately 2,094 lb (950kg) weight.

The FSG-1500 works with practically all types of engine cylinder heads, from passenger cars to commercial vehicles. The limiter is seat diameter (0.7 to 2.4 inches/Ø18 to 60mm) and table size (up to 59 inches/1500mm). Accepts heads from gasoline, alcohol, diesel and flex engines. The ISO 30 taper ensures compatibility with standard market cutting tools. Ideal for machine shops servicing from motorcycles to light trucks.

The manual milling machine like the FSG-1500 requires the operator to control all movements and adjustments, providing more flexibility for varied work. The automatic executes pre-programmed cycles, being faster in serial production. The manual is cheaper, takes less space and allows corrections during the process. For machine shops doing diverse services on varied cylinder heads, the manual offers better cost-benefit and versatility.

The cylinder head is fixed on the milling machine table and precisely aligned. The cutting tool is mounted in the ISO 30 taper of the tool spindle. The operator positions the tool over the defective seat, adjusts depth and speed (0-350rpm on the FSG-1500). The cutting movement removes damaged material, creating smooth surface and correct angle. The pneumatic system (87 PSI/6 bar) facilitates precise spindle movement.

Basic maintenance includes regular lubrication of guides and spindles, cleaning after use and checking compressed air pressure (87 PSI/6 bar). Cutting tools need periodic sharpening to maintain precision. The 1hp electric motor requires standard preventive maintenance. Important to keep the table free of chips and protect guides from impacts. With adequate maintenance, the FSG-1500 offers years of reliable operation.
