When the drill tool D, which is arranged at one end of T (right side in the drawing) and has finished drilling work, is moved to the chip removal standby position O2, the clip tool is opened to form a drill tool receiving system. Immediately after the drill tool enters the sandwiching position O3 in the clip tool, immediately after the base D of the drill tool D is reached.
Lightly sandwiching a, and then following low speed reverse rotation CT of spindle S and Z-axis upward movement (+ Z)
Eliminate. The bifurcated clip 10 includes a table T
A base 11 is attached to a sandwiching position O3 at one end (right side in the drawing) of the column, and an air or electromagnetic actuator A is built in the column upper portion 12, and the bifurcated sandwiching pieces 13 and 14 for pivotally supporting the actuator are provided. Open and close with A.

The drill tool D is a chuck C of the spindle S.
Define Z1: tool length measurement dimension from the part mounted on S to the cutting edge, and Z2: actual tool length. The definitions for the chip removal standby position O2 and the sandwiching position O3 from the origin position O1 of each axis are as follows. Z-KP: Dimension from the Z-axis origin spindle end surface to the chip removal plate. X-KWP: Dimension from the origin of the X-axis to the chip removal standby point. Y-KWP: Dimension from the Y-axis origin to the chip removal standby point. X-KP: Dimension from the X-axis origin to the chip removal point. Y-KP: Dimension from the Y-axis origin to the chip removal point.

Next, the operation state will be described with reference to the flow charts of FIGS. At the start (A), the X, Y, Z coordinate current value storage memory is canceled, and at the time of M48 command (A), the X, Y, Z coordinate current value is stored. Then Z
Axis origin return (c) is performed, and the S code currently commanded is saved (d). At this time, the spindle stop (e) is confirmed and the X and Y axis origin return (f) is performed. If the spindle is rotating, the forward / reverse rotation is confirmed and stored (ki), and the spindle stop command (M0
5) is transmitted to perform origin return (X) for the X and Y axes.

Then, the main spindle performs "X-axis chip removal standby point movement and Y-axis chip removal standby point movement" (X), and further "Z
Axial movement {(Z-KP)-(Z1-Z2)} "(). Waiting for this, "Chip removal plate open command (M4
3) ”(sa) is transmitted. At the same time, "Check the opening of the chip removing plate" (S), and "Move X-axis chip removal point and Y-axis chip removal point and reverse spindle" (S),
In addition, it sends a "chip removal plate closing command (M44)" (C). At the same time, "dwell 1 second" (so) is performed, "Z axis moves the actual tool length + 5 mm" (ta), then "spindle stop command (M05)" (h) and "S code return command". "(T)" is issued to "remember which one of the forward and reverse rotations of the spindle is in memory" (TE).

If the spindle is stopped, "Z-axis origin movement" (NA) and "X, Y-axis origin movement" (D) are carried out, "return each axis to its original position and finish" (NU). To do. If the spindle is rotating, the "forward or reverse rotation command" (ne) and "memory cancel" (no) are executed, and then the "Z-axis origin movement" is performed.
(Na) and "X, Y axis origin movement" (d) are performed, and "return each axis to the original position and end" (nu).
