Abstract

1357056 Abrading HONDA GIKEN KOGYO KK and HONDA KOKI KK 7 Nov 1972 [8 Nov 1971] 51374/72 Heading B3D A method of removing sharp edges of a machined bore or bores and burrs appendant thereto from a workpiece comprises forcing a mass of grinding medium, composed of oil and abrasive grits admixed thereinto and tending to deposit under gravity, through the machined bore alternately in one direction and then the other using aligned piston and cylinder assemblies above and below the workpiece in a manner such that during the pass in said one direction the upper portion of the mass consisting substantially of only the viscous oil passes through the bore ahead of the lower portion including an increasing proportion of abrasive grit, and such that during the pass in the said other direction, the lower portion passes through the bore ahead of the upper portion. A number of workpieces W may be mounted in respective workholders 6 located on a turntable 7 indexable about a shaft b to bring the workpieces successively between upper and lower piston-cylinder assemblies 1, 12. The upper assembly is secured to the machine frame a and has a pair of pistons 2, 2<SP>1</SP> interconnected by a rod slidable through a partition dividing the assembly into upper and lower chambers. The lower assembly can be raised and lowered by an actuator 13 and has a pair of pistons 9, 12 interconnected by a rod which passes through a partition and extends beyond the lower end of the assembly, the rod having an enlargement for actuating limit switches LS1, LS2, LS3. The adjacent ends of the assemblies have walls formed with aligned bores 25, 26. The medium 19 of viscous oil and abrasive particles is initially above the piston 19 of the lower assembly which, at the start of the operation, is raised by the actuator 13 to clamp the turntable against the bottom of the upper assembly. The pistons of both the lower and upper assemblies are then raised so that the upper portion of the medium 19 consisting mostly of the viscous oil passes through the bore 26, bore in the workpiece and bore 25 and then the lower portion of the medium passes through the bores. When the direction of movement of the pistons is reversed, first the lower and then the upper portion of the medium passes back through the bores into the lower assembly. The pistons 9, 12 continue downwardly after stopping of the upper pistons to draw a washing oil D from a tank 17, through the bore in the workpiece and the bore 26. The washing oil is prevented from mixing with the grinding medium 19 by a float plate 8. The actuator 13 then lowers the assembly 20 and at the same time pistons 9 and 12 are raised sufficiently for the washing oil above plate 8 to be expelled through bore 26 into a pan 18 for return to a sump 21 which has a pump 22 for supplying oil to the tank to a level controlled by a float switch 16.
