about

The invention relates to the production of abrasive tools, including those of superhard materials (STM), used for grinding and finishing parts, the quality of which surfaces are raised are high requirements, and the mohset is used for impregnating abrasive tools in bearing and tooling. Industries, as well as in engineering, related to the machining of parts from difficult-to-work alloyed materials by cryptography, honing or superfinishing.

A composition is known for impregnating abrasive tools with lubricants of a mixture of molybdenum disulfide with ferrous oxide, copper and one ij.

However, the known composition does not exclude the appearance of burns on the treated surface, especially when grinding parts from hard-to-machine steel.

The closest to the invention to the technical essence and the achieved result is the composition for

impregnation of abrasive tools, including phenol-formaldehyde-room components and epoxy resin Dianova 12.

The known composition does not provide a sufficiently low temperature in the zone of contact between the tool and the part and does not exclude the occurrence of application on the treated surface.

The aim of the invention is to reduce the temperature in the zone of contact between the tool and the part and to improve the quality of the surface being processed.

This goal is achieved by the fact that the composition for impregnating abrasive 5 tools, including the phenol-formaldehyde component and epoxy diane resin, contains phenol-formaldehyde as a phenol-formaldehyde component and contains pulverbakelite and, additionally, molybdenum diselenide at the following ratio of components, wt.%: Pulverbequelite 80-87 Eq. - 3-5 Molybdenum diselenide 10-15

5 Polymer binder compositions are given in table. one.

resin ..3 Polymer binder is used as solutions in alcohol or aceto with a density of 0.9-0.95 g / cm at 20 °. Example 1. A solution of a polymer binder composition 1 in acetone with a density of 0.9 g / cm at 20 ° C and used for impregnating grinding wheels. Example 2. A solution of a polymeric binder composition 2 in acetone with a density of 0.95 g / cm at 20 ° C is prepared and used for impregnating grinding wheels. Example 3. A solution of a polymeric binder composition 3 in ethanol with a density of 0.93 is prepared. For the impregnation of wheels, a special installation with an ultrasonic generator UZU-0.1 is used for impregnation of grinding wheels.

12 84, 80 Impregnation modes: shutter speed in bstgpe (holding time depends on the size of the wheels and the degree of impregnation); heat treatment for 2 hours at 50-60 ° and 2 hours at 120-140 °. After heat treatment, the circles are cooled in air. Impregnated wheels are tested when grinding the inner cylindrical surface of the inner rings of the bearing 1000095Y stainless 1IXI8IM. Equipment - internal grinding machine from Bumard company. Grinding modes: wheel speed 18.8 m / s, product speed 16 m / min, transverse feed 0.0020, 004 mm / two-stroke, number of double strokes per minute 60, cycle time 20 s .
