How to dress Grinding Wheels? Before you start dressing a grinder wheel, make sure you check your grinding wheel dressing tool and grinding wheel for cracks by visual inspection and performing the ring test.

Taken all necessary precaution measures and got geared up, you’re ready to begin. The procedure is more or less completely the same for all discussed bench grinder dresser types: diamond dressers, dressing sticks, and star dressers. Truing and dressing are performed by holding it against the rotating grinding wheel surface and moving it back and forth across the wheel face.

Turn on the grinder and allow the wheel to reach full RPM. Start by positioning the dresser off-center to one end of the wheel. If you’re using a star dresser, you’ll place its legs behind the rest, apply the head of the dresser containing discs or cutters with force on the surface of the grinding wheel and you’ll run the tool back and forth. In case you are using a wide-face diamond dresser, you’ll apply its whole face with light pressure against the whole surface of the wheel and move it back and forth just a bit. The dressing stick is also placed against the wheel face and moved back and forth. As for the single point diamond dressers, they are placed in a holder, point set at 10 to 15-degree angle pointing toward the direction of wheel rotation (make sure you turn the tool frequently 20-40 degrees to maintain a sharp point).

The whole process of dressing is not labor-intensive and will take about five minutes. Wheels should be trued & dressed just enough to establish egocentricity or to expose new sharp abrasive grains to the work-piece. The process is over after you get a nice flat surface of the wheel that looks brand new.

VALUE OF DRESSING WHEELS;

Using the appropriate diamond dressers or other diamond products on these abrasive wheels performs three important functions:

1. trues or re-balances the wheel to a concentric shape;
2. dislodges buildup of abrasive particles and bits of metal, exposing new abrasive surfaces of the wheel for more accurate grinding; 
3. cleans the wheel, renewing its edge and revealing sharper abrasive and fresh grains.

STEPS TO DRESS A GRINDING WHEEL

Here are the steps to take to effectively and properly dress a grinding wheel.

• Step 1: Determine the proper dressing tool for the wheel. Make sure the grit of the dressing tool is finer by one or two sizes than the abrasive surface of the grinding wheel. Also, make sure you choose the appropriate shape of the dressing tool to coincide with your grinding wheel.
• Step 2： Turn your grinding machine's coolant pump off (if it has one).
• Step 3：Turn on your grinding machine and allow it to operate until it reaches its full RPM; you might choose to turn off your spindle motor, or keep it running, based on your personal preference or experience. Excessive need for truing might dictate keeping the motor on, rather than turning it on and off.
• Step 4： Using light to medium pressure, apply the dressing tool to your wheel's abrasive section; continue applying pressure just until the wheel stops rotating.
• Step 5：Repeat Step 4 until the dressing tool until the grinding wheel feels as if it is pulling the dressing tool away from you.
• Step 6：Repeat Steps 4 and 5 as many times as necessary (four to five times, typically), depending on your grinding wheel's surface condition.
