7" Finishing Valve Grinding Wheel SVS, SVSIID

Kwik-Way 7” Finishing Valve Grinding Wheel - Precision for Mirror-Like Valve Finishes

This 7-inch (178mm) Finishing Valve Grinding Wheel is a specialized abrasive engineered by Kwik-Way to achieve an exceptionally smooth, mirror-like finish on valve faces. Compatible with Kwik-Way SVS and SVSII Deluxe valve refacers, this wheel operates at 3450 RPM and leverages Kwik-Way’s proven abrasive formulation, optimized to work in conjunction with Kwik-Way grinding oil and the machine’s precision chuck for superior results. Proper dressing to a “glassy smooth” surface (always with coolant) and taking very light, slow cuts are crucial for optimal finish. The use of Keyser Mirror Finish valve grinding aid (000-2111-66) is also recommended for enhanced surface quality, chatter elimination, and extended stone life.

Kwik-Way 7” Finishing Valve Grinding Wheel - Engineered for Elite Valve Surface Quality

The 7-inch Finishing Valve Grinding Wheel is a precision abrasive component meticulously designed by Kwik-Way to deliver the ultimate in surface quality for valve faces. This wheel is essential for engine rebuilders aiming to achieve an exceptionally smooth, high-quality, and often mirror-like finish on valves, crucial for optimal engine performance.

Purpose and Application: Achieving a Superior Finish:

• This is a dedicated Finishing Wheel, specifically intended to refine the valve face surface. It is part of Kwik-Way’s comprehensive range of grinding wheels, where selecting the correct abrasive formulation is vital to ensure a smooth and accurate finish based on the valve material being ground.

• When aiming for a highly polished surface, specific dressing techniques are recommended: making slower traverses into the diamond point when dressing the wheel, followed by a sweep back with no additional feed.

Compatibility and Operational Specifications:

• With a standard 7-inch (178mm) diameter, this grinding wheel is perfectly compatible with Kwik-Way SVS and SVSII Deluxe valve refacer models.

• On these machines, the valve grinding wheel operates efficiently at a fixed speed of 3450 RPM, designed for consistent and reliable finishing performance.

Performance, Quality, and System Synergy:

• Kwik-Way grinding stones, including this finishing wheel, utilize the same reliable abrasive formulation that Kwik-Way has historically employed. This ensures consistent quality and performance.

• Achieving the best possible finish is a synergistic process, dependent on the harmonious combination of these specially formulated stones, genuine Kwik-Way grinding oil, and the precision engineering of Kwik-Way’s exclusive chuck design. Using other, non-Kwik-Way products may negatively affect the quality of the finish and potentially reduce the lifespan of the stone.

• The variable speed chuck and precise spindle speed capabilities of the SVSII Deluxe refacer further contribute to meeting the diverse grinding requirements of various valve materials and diameters, consistently ensuring a superior finish.

• For an exceptional surface quality, and to effectively eliminate chatter and wheel loading, the use of Keyser Mirror Finish valve grinding aid (000-2111-66) is highly recommended. This aid is specifically formulated for materials like titanium, stainless, and stellite valves, and helps to significantly increase stone life.

Usage and Maintenance for Optimal Finish:

• Wheel Dressing: A new or re-installed wheel must be dressed prior to its first use. The crucial process of dressing the grinding wheel face restores its condition to a smooth, true, and flat surface, which is essential for producing the best possible finish on the valve face. For the ultimate valve face finish, the grinding wheel should be dressed to a “glassy smooth” surface.

• Coolant Use: It is imperative to always use coolant when dressing the grinding wheel to prevent heat buildup, maintain the wheel’s integrity, and ensure clean material removal.

• Grinding Technique: Good grinding practice involves taking very light cuts and slowly passing the wheel back and forth across the valve face multiple times. This methodical approach ensures a controlled and fine material removal for a superior finish.

• Wheel Performance Adjustments: If the wheel acts too soft (e.g., not holding size or requiring excessive dressing), its perceived hardness can be increased by decreasing the work speed, traverse speed, or infeed. Dressing at a slower traverse speed can also help to condition the wheel for a harder action.

• Cleanliness: Valves should always be thoroughly cleaned and degreased before grinding to prevent the grinding wheel from “loading up” with residue. The grinding oil should also be meticulously kept free of contaminants for optimal performance, as it is specifically formulated to work in harmony with Kwik-Way grinding stones.

This 7-inch Finishing Valve Grinding Wheel is an essential investment for any workshop seeking to achieve the highest standards of valve face quality and precision using Kwik-Way SVS and SVSII refacers, especially when combined with Keyser Mirror Finish valve grinding aid.
