SDDD Resin Bond Diamond & CBN Truing Stick

The SDDD Resin Bond Diamond & CBN Truing Stick is designed to accurately true and condition diamond and CBN grinding wheels without damaging their cutting surfaces. Made with a controlled abrasive matrix, this truing stick helps restore wheel geometry, remove glazing, and maintain optimal wheel sharpness.

Engineered for resin bond super abrasive wheels, the SDDD truing stick ensures consistent contact and surface renewal, enhancing grinding precision and extending wheel life. Ideal for use on resin bond diamond, vitrified, and CBN wheels, it provides a clean, efficient, and non-destructive truing process for tool rooms and production grinding operations.

Braemar stocks 0.375″, 0.437″, & 0.625″ SDDD Dressers for immediate delivery.

Applications:

• Truing resin bond diamond wheels (1A1, 11V9, 6A2, etc.)

• Conditioning CBN wheels for hardened steels and carbide grinding

• Ideal for use in precision tool grinding and finishing operations

INSTRUCTIONS

Step 1: Place tool in holder. Expose not more than 1/2″ of S.D.D.D tool (on radius dresser more is allowed).

Step 2: Turn off work light to better observe active sparking interface. Turn off coolant.

Step 3: Set up feed (tool travel) to move at a moderate to fast speed.  An active sparking interface is the desired effect. Excessive tool wear will be the result of a slow feed setting.

Step 4: Set up down feed using the chart below. Correct down feed is determined by the hardness and grit size of the wheel. It is important to note at this point that more is better when it comes to calculating the down feed of the wheel to be trued.   DO NOT “Baby” the tool! Cautious down feeding of the wheel to be trued will simply wear away the S.D.D.D tool with no positive effect on the diamond or CBN wheel.

Step 5: Allow S.D.D.D Dresser to make several passes (2-3) at this position. (Truing in one direction will only leave a crown on the wheel.)

Step 6: Reduce the down feed of the wheel with each set of 3 passes across the wheel, for example by going from 0.001 – to 0.0005- and then to 0.0002 until the wheel is trued. A wheel trued in this manner will exhibit excellent cutting action on work pieces and leave a correct surface finish (in accordance with the grit size of diamond or CBN wheel).

The SDDD Resin Bond Diamond & CBN Truing Stick will help the following conditions

1. Roundness & Concentricity – During manufacturing or after use, a wheel may develop runout (wobble or eccentricity). Truing brings the wheel back to perfect round so it grinds smoothly and evenly.
2. Exposes Fresh Diamond – In resin bonds, diamond grains can dull or get pulled out unevenly. Truing removes the top loaded/dull layer and exposes sharp, fresh diamond for efficient cutting.
3. Corrects Wheel Face Geometry – If you need a flat face, a specific form, or precise dimensions (like for tool grinding), truing makes sure the wheel surface matches the required shape.
4. Prevents Vibration & Poor Finish – An untrue wheel causes chatter, heat, and poor surface finish. Truing improves surface quality and consistency.
5. Increases Wheel Life – By maintaining the correct form and sharpness, truing prevents localized wear and extends the useful life of the wheel.
