ASA is your source for truing and redressing wheels up to 20in diameter with 1 week turn around! Are you having problems with wheel run-out, form not within specification or want to change the wheel form?
What exactly is the difference between “Truing” and “Dressing” a wheel?
To produce the highest-quality work, wheels must be trued after being mounted on a spindle. After mounting, there will always be some eccentricity. This will affect the final workpiece in several ways. Some benefits of this process are:
- Establishes concentricity
- Introduces form or shape into a wheel
Next comes dressing; this process always comes second. While superabrasive wheels are mostly self-sharpening, the material used can occasionally cause the wheel to dull. Dressing sharpens by removing this material and helps to expose the fresh edges of the wheel.
- Operation that produces crystal exposure or chip clearance.
- Return wheel to original dimensions
Truing and Dressing requires a two-step technique:
- Truing (Profiling)
- Wheel concentric to the spindle axis
- Shape wheel profile to geometry
- Fracture dull abrasives
- Dressing (Sharpening)
- Expose abrasive above bond
- Provide chip clearance
The typical materials used in dressing technique are Aluminum Oxide or Silicon Carbide Dressing Sticks.
