Description

High-precision diamond dresser also named diamond roller are high-efficiency, long-life, and low-cost grinding wheel dressing tools used for mass forming and grinding of special machine tools and gear grinders.

The working principle of the diamond roller is:

By installing on the dressing device of the grinder, the diamond dresser is used to dress the ordinary ceramic grinding wheel or CBN grinding wheel. After the grinding wheel is formed, the parts are ground, so that the contour, precision and size of the diamond roller are copied to the grinding wheel through the grinding wheel. The surface of the machined part. Its characteristics are that the machine tool is easy to operate, does not require high technical requirements for the operators, the processed products have good accuracy and consistency, and the quality is stable. It can significantly improve production efficiency and product quality, reduce manufacturing costs, and easily realize grinding processing automation. Compared with the traditional single-point diamond pen dressing, the production efficiency is greatly improved, and the surface quality and precision of the processed parts are higher, which is especially suitable for high-precision and mass production.

According to different manufacturing process methods, diamond dresser can be divided into:

HNT sintered diamond dresser: It can be subdivided into two types, hand-planted sintered roller and randomly distributed sintered roller, with strong durability;

HNT electroplated diamond roller: high precision, can produce small and complex shape roller;

CVD diamond dresser: new material, good dressing effect on CBN grinding wheel.

(1) The particle size of diamond should be one size coarser than that of the grinding wheel to be dressed, and the diamond particle size should be close to the same, and the particle shape should be approximately spherical. The commonly used particle size is 36 # ～100 #.

(2) Generally, the direction of the linear velocity at the contact point of the roller and the grinding wheel is in the same direction, and the ratio of the linear velocity of the roller to the linear velocity of the grinding wheel (qd value) is taken as +0.3～+0.7, which is better, and should not exceed +1; when dressing The cutting amount of the roller should be 0.5～1 μm per revolution of the grinding wheel, and the total amount of the grinding wheel should be 0.02～0.04 mm each time; the light repair time should be as small as possible.

(3) The manufacturing error of the diamond roller should be less than 1/2 of the workpiece tolerance, and the clearance between the roller hole and the mounting bearing should be 2 to 4 μm.

(4) Natural or synthetic diamonds can be used, and synthetic diamonds must be high-strength diamonds, such as diamond SCD for grinding steel or high-strength diamond SMD.

(5) When manufacturing rollers, rollers with general precision can be manufactured by external plating and sintering methods, and rollers with high precision and complex profiles should be manufactured by internal plating, and they can be ground and trimmed.

(6) When the diamond dresser is dressing the grinding wheel, it must follow the action program of fast forward (cannot touch the grinding wheel) → slow forward (feed at the required cutting speed) → light repair → exit, and no step is allowed, otherwise the life of the roller cannot be guaranteed.
