 Data of diamond roller

Classification of high precision diamond rollers:

(1) Sintering method: it is divided into two kinds: hand planted sintering roller and randomly distributed sintering roller, with strong durability;

(2) Electroplating method; High precision manufacturing of small and complex shape roller;

(3) CVD roller: new material, good dressing effect for CBN wheel.

At present, sintering method is the main method in China, which has longer service life and more stable performance than electroplating method. On the contrary, electroplating method is widely used in foreign countries. The following figure shows the manufacturing method and characteristics of sintered diamond roller and electroplated diamond roller.

2. Manufacturing technology of high precision diamond roller

The manufacturing process of the sintering process is the first mock exam according to the drawing, followed by artificial implantation, and the large diamond is embedded in the mold according to a certain density and orderly. After sintering, the sintering furnace is sintered by powder metallurgy technology, then the mold is removed, the diamond face is used as the benchmark, the hole and the end face datum are machined, and then the grinding wheel is repaired on the grinder. At this time, the diamond roller is a blank, and there is a dimensional accuracy deviation. The deviation value should be measured by the instrument of the testing center, and the appropriate trimming allowance should be calculated. Finally, on the special trimming machine tool, after repeated grinding and testing for many times, until it meets the requirements of the finished product drawing.

The manufacturing process of electroplating method is as follows: according to the technical requirements of the cross section of the parts, a mold is made, artificial diamond is electroplated, the binder (low melting point alloy) is bonded with the steel core, the matrix of the grinding tool is removed by gold cutting (datum conversion), the diamond is evenly exposed, the grinding wheel is trimmed on the grinder, a workpiece is replica, and all the technical requirements of the workpiece surface are measured in the testing center, Qualified is the finished product.

3. Summary of failure causes and treatment methods of high precision diamond roller during dressing

High precision diamond roller often appears in the process of dressing, such as loud noise, chatter marks, grinding burn, rough surface, local protrusion and so on. The following table introduces the causes and solutions of the above five conditions.
