PROCESS EQUIPMENT UPDATE
of defi ned viscosity. This grinding medium is caused to fl ow through or over the area of the component to be deburred in alternating directions at a defi ned pressure level by means of hydraulically powered pistons. Deburring, cleaning, rounding and hardening of the
surface in a single step is made possible by the so-called pinfl ow process. The workpieces to be processed are clamped in a part-specifi c fi xture that is laid out as a container, is fi lled with a processing medium (small steel balls) and is located in the machine’s process chamber. Vibrators then cause the fi xture to oscillate horizontally, thus resulting in relative motion between the workpiece and the deburring medium. The resultant kinetic energy of the steel balls is transferred to the workpiece to process its external and internal surfaces, and the deburring eff ect is also apparent in diffi cult to access places. ■
