The Kwik-Way CenterLine Chuck is what makes the SVS II Valve Refacer a cut above all the rest. Other Valve Refacers use Chucks, referred to as "center less". These use rollers to grip the valve stem while the Kwik-way Chuck uses two sets of independent balls that grip the stem at two very distinct points. The advantage being, if you have a center less chuck and you're trying to grind an in-service valve, if there is any out-of-round on the valve stem, that out-of-round is transferred from the rollers on the center less chuck to the valve face. So your face run out will be no better than your stem run-out.
With the Kwik-way Chuck, since it uses two sets of balls that capture the valve in the wear area of the stem, will automatically re-centerline the valve. What that means is when we grind the valve, the face will come out true to the center line of the stem that actually rides in the valve guide.
In other words, if there is some wear on the stem surface the Kwik-Way Chuck is going to compensate for that wear in such a way that the resulting ground valve face is perfectly centered when the valve is back in the engine.
Some valve manufacturers design their valves with a tapered stem. Because of the unique way The Kwik-Way Chuck grabs the valve stem, taper has no influence on the precision of the positioning of the valve in the chuck. Other Valve Refacer Chucks may cause the valve to tilt in the chuck. Without a way to compensate for valve stem taper, you cannot reface the valve with the same amount of accuracy as with a Kwik-Way machine.
The Kwik-Way Chuck is air activated. You simply push a button that will release the two sets of balls and allow you to insert the valve. You will have a range of 4mm to 14.3mm with the standard or high perfermance valve chuck.
Another type if chuck used on other machines is a collet chuck. To give you the range of 4mm to 14.3mm you would need at least 5 or as many as 9 different collets to cover that range. As you now know, with the SVS II, there is no change over required for various stem diameters. And as you change collets there can be problems with repeatability because you can put the collet in the receiver with dirt or grit between the receiver and the collet. In that case, you will get inaccuracy. Also, if you have a tapered valve, the collet will not compress to the same tension at both points so again with a collet chuck and a tapered valve you get inaccuracy.
The same is true with an out-of-round valve. Because the collet wants to compress uniformly around the circumference of the stem. The bottom line is that the other chucks grab the valve stem using a greater amount of the valve surface, which can be a problem if there are any irregularities in that valve.
The SVS II D comes standard with tip grinding and rocker grinding capability. It can also chamfer tips. There are no optional accessories necessary to perform these functions. Unlike with other machines where you will find that you have to purchase additional accessories in order to do these other jobs or to get the same amount of valve stem diameter range as the Kwik-Way SVS II Deluxe Valve Refacer.
You can transition from valve refacing to tip grinding or rocker arm grinding operations for shaft mounted types of rockers in less than minutes. And it's all standard with the machine.
Kwik-Way Valve Grinding Wheels are very reasonably priced. Our wheels are formulated and manufactured by one of the largest manufacturers of grinding wheels in the world and they are designed specifically for our machines. Kwik-Way offers various types of wheels. We have general purpose, finishing, titanium, and hard alloy, so no matter what type of material comes into your shop you are going to be able to handle it.
To change and redress a wheel on the SVS II Deluxe machine only takes about 2 minutes. We find that our general purpose wheel is sufficient for most operations, but of course, if you get a high performance valve or titanium alloy valve, you will need to change to a different grinding wheel.
We also offer a Valve Cabinet designed specifically for the SVS II D machine. The footprint of the cabinet allows for a good ergonomic workstation. With excellent storage below in the cabinet. We find that some people already have areas in their shop that they have a station designed for and as long as the bench is adequate to support the weight of the machine it will work fine.
The SVS II Deluxe Valve Refacer is sold all over the world. Kwik-Way is by far the largest provider of valve equipment in the entire world. We have various voltages available and also various chuck capacities.
The SVS II Deluxe Valve Refacer comes with a unique warranty we call the 5-2-1 warranty. The base of the unit is warranted for 5 years, all other parts for 2 years and the first year everything is warranted, parts, labor and electrics. We also have a exclusive 3 year limited warranty on the Chuck. We warrant it against loss of accuracy.
Most all Funny and Top Fuel Race Teams are using a Kwik-Way Valve Machine. If you look at their trailers you will find they have Kwik-Way valve grinders on them. The only equipment they trust for regrinding high performance engine valves is a Kwik-Way machine. And while many companies will give their equipment to these types of organizations in exchange for the promotional value, Kwik-Way does not. So if a high performance shop is using a Kwik-Way machine it is by their choice and they paid to have that machine.
Frustrating the Competition for 85 Years
Many have tried; Some have come close
But None have duplicated the Accuracy of the
Kwik-Way Six-Ball Centerlining Chuck
Based on fundamental design principles that existed in 1920 and still exist today,
The Most Accurate Valve Grinding System Ever Conceived: .0002 or less *
* with High Performance Chuck
The Kwik-Way Principle: CENTERLINE
The Kwik-Way "Centerlining System" is the only way to correct and align valve faces to that portion of the valve stem operating in the guide. Unless a valve is scientifically aligned, the valve face will be ground eccentric to its true center. A new valve is true and mechanically accurate in all its proportions. The valve face and stem are concentric with the same centerline.
Warping occurs only in that part of the valve that is subject to extreme heat - the portion above the guide and in the valve head. To correct a warped valve so it will function properly when replaced in the engine, the valve face must be restored to concentricity with the portion of the stem that operates in the guide. The Kwik-Way "Centerlining System" assures this alignment and accuracy.
EXCLUSIVE SIX-BALL CHUCK DESIGN
Six-ball alignment for perfect grinding: Every Kwik-Way chuck features two sets of balls - 3 balls to a set - which grip the valve stem on that part which travels in the valve guide.
This exclusive six-ball, compound compensating, self-centering chuck automatically aligns the valve, refacing it concentric with the original centerline of the valve system
Every Kwik-Way SVS II is equipped with this air-activated, self-aligning six-ball chuck that is accurate to within .0002” with the High Performance Chuck (.0005" with standard chuck)
Six-Ball Chuck: Air-Activated • Self-Aligning • No other system is as accurate and precise
The main advantage that others have failed to duplicate is Kwik-Way’s exclusive six-ball centerlining chuck. The two sets of balls (three in each set), automatically find the existing valve stem centerline. This chuck handles any valve stem from 4mm to 14.3mm. Other machines can require as many as nine separate collets to achieve the same range.
Collet and "so-called centerless grinders" transfer wear from the valve stem directly to the valve face during grinding. Historically, these designs are only capable of achieving their advertised accuracy on NEW valves. The Kwik-Way Six-Ball, Centerlining Chuck design triangulates (or centers in) the wear area of the valve stem in order to grind the face concentric to the actual stem centerline. Because the two sets of centering balls act independently, taper on the valve stem will not affect accuracy (even on new valves). This feature is available EXCLUSIVELY with the SIX-BALL CENTERLINING CHUCK - a standard feature on all KWIK-WAY SVS II DELUXE Valve Refacers.
The Kwik-Way design features dovetail ways which remain adjustable for long-term accuracy. The valve position swivel plate is indexed in 1º increments to ensure accuracy of grinding angles from 13º to 62º.
