ABOUT Diamond ROTARY Dressers
Diamond rotary dressers play two critical roles in maintaining grinding performance over time: dressing the wheel to expose fresh abrasive grains and truing the wheel to restore and maintain its intended shape. Together, these functions support:
Accurate profile geometry
Consistent surface finish
Reduced thermal load on the workpiece
PLUNGE DRESSING with profile rollers
Plunge dressing is used when maximum form control and speed are required. The dresser moves vertically, plunging the shape into the grinding wheel.
Precise profile control for intricate workpieces
Tight tolerances on form and profile
Accurate, controlled material removal
Short dressing times and long dressing intervals
This type of diamond rotary dresser may be reverse plated or sintered.
Traverse Dressing with dressing discs
Traverse dressing offers the most flexibility as the dressing disc is programmed to move laterally across the grinding wheel to form its shape.
Uniform wheel conditioning for improved finish
Extended service life with repairable options
Flexibility for complex contours and wheel forms
Economical self-sharpening impregnated discs
This type of diamond rotary dresser is typically sintered and often reinforced with CVD.

CDT experts are always available to help you with technical product support and offer guidelines for using the dressing tools we produce. However, here are some basic tips for your convenience:
Setup and Safety:
• Ensure the grinding machine is turned off before installation.
• Mount the rotary diamond dressing wheel securely on the grinder's spindle.
• Always wear appropriate personal protective equipment (PPE) and maintain a safe distance from the rotating wheel during operation.
Positioning and Alignment:
• Position the dressing wheel in proximity to the grinding wheel to be dressed.
• Ensure that the dressing wheel is properly aligned with the grinding wheel's surface.
• Adjust the angle and position as needed to achieve the desired profile on the grinding wheel.
Dressing Process:
• Turn on the grinding machine and allow it to reach its operational speed.
• Gently bring the rotary diamond dressing wheel into contact with the grinding wheel's surface.
• Maintain a consistent and steady feed rate to avoid uneven dressing.
• Observe the dressing process to ensure the desired shape and sharpness are achieved.
• Avoid applying excessive pressure, as this can cause premature wear of the dressing wheel.

CDT holds ISO Certification and provides warranty coverage for all products. However, here are some tips to maintain the longevity of your investment:
• Use a coolant or lubricant to prevent excessive heat buildup during dressing.
• After dressing, disengage the dressing wheel, turn off the grinding machine, and clean any residual debris or dust from the dressing process to extend the life of your equipment.
• Store the rotary diamond dressing wheel in a safe and dry place when not in use to prevent damage or contamination.
