As the finishing and forming method of diamond roller not only has a short finishing time, but also can trim out various modalities, keep good surface precision, and is convenient for finishing operation, whose using effect has gradually been recognized by people. It has been more and more widely used in production. But in the design, manufacture and use of diamond roller, we should pay attention to the following points:

A, The particle size of diamond should be thicker than that of the processed grinding wheel, and we should also select diamond particle that is close to others with the shape of approximate spherical particle. The commonly used particle sizes are 36 # ~ 100 #.

B, It is better to adopt the linear velocity direction of the contact point of diamond roller and grinding wheel, and the ratio (qd) + 0. 3~ + 0. 7 of the linear velocity of diamond roller and grinding wheel, which shall not exceed + 1; When fnishing, the cutting quantity of diamond roller is advised to be  0. 5~1 μm, and the total amount of grinding wheel should be 0. 02 ~ 0. 4 mm.

C, The manufacturing error of diamond roller should be less than about half of the tolerance of workpieces, and the fitting clearance of roller hole and installed roller bearings should be 2~4 μm.

D, We can use natural diamond or synthetic diamond that must have high strength, such as special diamond for grinding steel SCD or diamond SMD with high strength.

E, When manufacturing diamond roller, the roller with general precision, can adopt the external plating method and the sintering method. High precision and complicated rollers should be produced by means of the internal plating.

F, When diamond roller trims grinding wheel, it must abide by the fast forward (can't touch grinding wheel), slow forward and other procedures. It can not be wrong, otherwise the life of diamond roller is difficult to guarantee.
