Selection of the right contact wheel is fully as important as the choice of abrasive belt. Grinding and Polishing

supplies a full line of standard Quick Change contact wheels to match - exactly - your grinding and finishing

requirements.  Use the information on this page to select the right wheel for most applications.  

Call on our grinding experts for specific information or help with special applications.

Selecting The Right Contact Wheel For The Job

Some things to consider:

* Harder wheels are used for faster cutting and produce a coarser finish

 

* Smaller wheel diameters are used for faster cutting and coarser finish

 

* Serrated wheels permit faster cut and result in a longer belt life (serrations allow the belt to cool)

 

* Higher speeds produce better finishes

 

* For a given material hard wheels remove more stock than soft wheels

TYPE "SAR"

Serrated Aluminum Wheel with Rubber fill. Roughing wheel only for aggressive grinding applications. This wheel is directional and

can only be run in one direction.

TYPE "PAR"

Plain Aluminum Wheel with Rubber fill. This has been found to be best for producing very close tolerances. It should be noted that the lathe must be in excellent condition.  Otherwise, use Type "PDDR".

TYPE "SDDR" 

Serrated Dual Density Rubber.

This wheel will produce tolerances nearly equal to type "PAR" but a better finish is achieved.  This wheel is directional and can only be run in one direction.

TYPE "PDDR"

Plain Dual Density Rubber.

This wheel is used where a good finish is needed with moderate stock removal and close tolerance.  This is the most commonly used wheel.

TYPE "PR" Plain Rubber.

A smooth face wheel, 70 to 90

durometer (specify) for applications

requiring the use of diamond or

structured abrasive belts. This wheel

can also be serrated (Type "SR") for

general purpose grinding.

TYPE "PA"

Plain Aluminum Face.

For grinding soft rubber rolls. .

Dressing The Contact Wheel -

IT IS IMPORTANT that all roll grinding contact wheels be "dressed" to the roll before grinding.  This assures squareness of the contact

wheel to the roll. Each time the grinder is removed, it is best to re-dress the wheel.

 

TO DRESS:

Place the grinder on the lathe and look for the best area of the roll.  Be sure the grinder is as square as possible. Clean the roll so pressure sensitive abrasive can be placed on the roll. This should go at least 3/4 way around the roll and be 50 to 80 grit. Start the grinder and move the contact wheel in until it makes contact with the abrasive. Move the grinder back-and-forth completely across the abrasive both ways. This must be repeated until the entire surface of the contact wheel has been dressed. Don't plunge cut.

 

WEAR EYE PROTECTION - KEEP HANDS CLEAR WHEN USING GRINDING EQUIPMENT

 

Recovering Used Wheels

Type "SAR" and "PAR" wheels have aluminum lands which, when worn down, can't be replaced.  They can be made into Type "SDDR", "PDDR", and "PR" wheels at some savings. The "SDDR", "PDDR", and "PR" type wheels can be recovered at considerable savings. It is strongly recommended that a spare contact wheel be ordered with the grinder.  Delivery on replacement wheels may require 6 to 8 weeks
