HOW TO CHOOSE THE RIGHT POLISHING SPEED

To obtain a perfect polish, beyond the choice of the compound and the buffing mop, 3 criteria are essential:

• The rotation speed of the disc
• The pressure exerted on the part
• As well as the polishing time

Regardless of the material to be polished, it is important to prevent heating on the surface of the part so as not to modify its surface state (waviness, orange peel).

If your polishing products, compounds and buffing mops, work correctly, the operator will not have to force the part, polishing will be done without deformation of the part, efficiently and quickly. 

CALCULATE THE ROTATION SPEED OF A BUFFING MOP

Depending on your part, your equipment and your expectations, a MERARD polishing expert will be able to advise you on the most suitable linear polishing speed.

You will then have to deduce the rotation speed of your grinder in rpm.

To help you :
1.     Refer to the graph below
2.     Identify the diameter of your buffing mop (in mm)
3.     Select the linear velocity (in m/s) that you want to achieve
4.     Calculate the speed of rotation (in rpm)

• When the buffing mop is new, its diameter is large => the rotation speed will be smaller.
• When the buffing mop will wear out, its diameter will decrease => the rotation speed will have to be increased to keep the same linear speed.

EXAMPLES OF SPEEDS DEPENDING ON MATERIALS 

• Precious metals    15 m/s
• Plastic Lacquer      20 m/s
• Steel                        25 m/s
• Copper brass         30 m/s
• Aluminium             40 m/s
