Solid Cast Iron Construction
Poured in the USA and machined in Cedar Rapids, Iowa, the 2 solid cast iron blocks that make up the Kwik-Way SVS II Deluxe valve grinder machine give strength and stability to the whole structure.
The weight of a solid cast iron base absorbs vibrations, dampens harmonics, eliminates chatter, and maintains accuracy for a very long service life.
Exclusive Six-ball Chuck Design
Every Kwik-Way valve refacer chuck features two sets of 3 balls each that grip the valve stem on that part which travels in the valve guide. This patented design ensures perfect concentricity between the stem and the valve head and provides precision and reliability.
The compound compensating, self-centering, six-ball chuck automatically aligns the valve, refacing it concentric with the original centerline of the valve system. This type of 2-point stem support is referred to as a “Centerless” grinding system.
The valve is kept firmly in place by pneumatic action, controlled either by a lock/release button or a convenient pedal. Pneumatic operated change-over also eliminates the need to switch off the motors when changing valves, reducing machining time and increasing life of motors.
The 6-ball chuck supports variable valve rotation speed, which allows the operator to adjust surface speed and ensure the best surface finish for a wide range of valve head diameters. The standard chuck supports valve stems between ø 4 and 14mm, and an optional chuck is available for larger diameters ranging from ø 11 to 21mm. Other valve grinding machines can require up to 9 separate collets to achieve the same range.
The chuck itself is mounted on the head, which can then be inclined up to 62°.
Valve Grinder Wheels
The Kwik-Way SVS II Deluxe centerless valve refacer is equipped standard with a 7” (178mm) vitrified grinding wheel, additional 3” (76mm) wheel, along with grinding oil and a diamond dresser. The retractable main wheel diamond dresser is set to the exact position of the wheel face to dress or re-sharpen the wheel as needed.
Kwik-Way’s separate, belt-driven spindle isolates any motor vibration or harmonics to provide a smooth “chatter free” finish and a wide variety of special wheels for grinding difficult metals, such as titanium or Inconel, are also available.
The Kwik-Way SVS II Deluxe grinder is equipped with a 1 gallon (3.8L) tank for the coolant.
