METHOD OF DIAMOND HONING OF HOLES OF PARTS OF FRICTION WITH HIGH COMPOSITE MATERIAL BASED ON NICKEL USING ULTRASOUND

摘要

Method of diamond honing of holes of parts of friction with high composite material based on nickel using ultrasound, in which the workpiece is fixed on honing machines with vertical-axis hole parts processing, and a working tool in the form hona-mandrel with fixed therein fine-grained diamond bars arranged coaxially of processed holes so that the diamond bars with a given force pressed against the surface processing, and Khonuu-mandrel provide rotational motion of normalized speed around its axis and smooth movement of a given velocity along the axis of the surface treatment and at the same time provide a longitudinal reverse ultrasonic vibrations from appropriate frequency and amplitude. Thus, the process of applying for your diamond grain size 1,0-5,0 mm bars made of synthetic diamond (AS) in conjunction organic V1-02 (ASM1 / 5V1-02 100%) and 100% diamond concentration, and the hon -opravku moved in the opening parts processing (depending on the composition of alloying elements in composite alloy) with speed 30,0-50,0 m / min., while providing smooth movement along the longitudinal axis hona processing at a speed of 5-10 m / min . and performing ultrasonic oscillation frequency 45-65 kHz, creating a specific pressure bars abrasive surface treatment in the range of 0.1-1.0 MPa.
