10. A method for processing group holes of a thin-wall cylinder is characterized in that: the thin-walled cylinder group hole processing device as claimed in any one of claims 1 to 9 is used for processing the group holes of the thin-walled cylinder (8), and comprises the following steps:
s1: sleeving a thin-wall cylinder (8) to be processed on the central rod (42), connecting two three-jaw end covers (46) to the central rod (42) in a threaded manner, sleeving the two three-jaw end covers (46) at two ends of the thin-wall cylinder (8) and expanding tightly, clamping and fixing the central rod (42) by using a three-jaw chuck (43) and a tip assembly, pouring spark oil into the processing pool (41) and submerging the spark oil in the thin-wall cylinder (8);
s2: moving the thin-wall cylinder (8) to be right below a tool electrode (52) by controlling the X-axis motion mechanism (1) and the Y-axis motion mechanism (2);
s3: starting the first motor (45) and the second motor (55), wherein the first motor (45) drives the thin-wall cylinder (8) to rotate, the second motor (55) drives the tool electrode (52) to rotate, and the tool electrode (52) and the thin-wall cylinder (8) have opposite rotating directions and the same rotating speed;
s4: the Z-axis movement mechanism (3) drives the electrode movement mechanism (5) to move close to the thin-wall cylinder (8) along the Z-axis direction until the plurality of discharging protrusions (53) start to discharge and machine group holes to be machined of the thin-wall cylinder (8);
s5: when the tool electrode (52) and the thin-wall cylinder (8) rotate for one circle, the Z-axis movement mechanism (3) feeds downwards for a set distance until the thin-wall cylinder (8) is processed with group holes;
s6: the Z-axis movement mechanism (3) drives the electrode movement mechanism (5) to move away from the thin-wall cylinder (8) along the Z-axis direction, and then the thin-wall cylinder (8) is taken down from the workpiece clamping mechanism (4).
