Electroplated diamond roller forming dressing method is characterized by short dressing time, complex shapes can be trimmed, good accuracy of shapes can be maintained, and convenient dressing operation. Its application effect has been gradually recognized by people, and it has been more and more widely used in production. However, the following points should be noted in the design, manufacture and use of electroplated diamond roller:
(1) The granularity of the diamond should be one size larger than that of the dressed grinding wheel, and the size of the diamond particle should be close to the same and the shape of the diamond particle should be approximately spherical. The commonly used particle size is 36#~100#.
(2) The linear velocity at the contact point of the roller and the grinding wheel is usually in the same direction, and the ratio (gd value) of the linear velocity of the roller to the linear velocity of the grinding wheel should be +0.3~+0.7, and should not exceed +1: the cutting amount of the roller during dressing is the cutting amount of the grinding wheel per revolution
0.5~1um is appropriate, and the total amount of grinding wheel dressing should be
0.02 ~ 0.04 mm; Light repair time as compressed as possible.
(3) The manufacturing error of electroplated diamond roller should be about 1/2 of the tolerance of the dry workpiece, and the fit clearance between the hole of the roller and the mounting bearing is 2~4um..
(4) Natural or artificial diamond can be used. The artificial diamond must be of high strength grade, such as diamond SCD for grinding steel or high strength diamond SMD. (5) During roller manufacturing, external plating and sintering can be used for roller with general precision, while internal plating can be used for high-precision and complex roller with grinding and dressing.
(6) When dressing the grinding wheel of electroplated diamond roller, it is necessary to follow the action procedure of fast forward (do not touch the grinding wheel)→ slow forward (feed at the required cutting speed)→ light repair → exit. No wrong steps are allowed, otherwise the life of the roller is difficult to be guaranteed.
