METHOD OF WORKPIECE BORING BY A 5-AXIS MACHINING DOUBLE-HOUSING MACHINE TOOL |
摘要 |
<p>A slip ring is accommodated in a ram 34. The slip ring includes a fixed portion 72 having a feed element connected to a power source and a movable portion 73 electrically connected to the feed element. The movable portion 73 includes a contact 75 for supplying electricity to a spindle unit 100 and an electric device of a spindle head 118. After determining the position of a saddle 32 in a Y-axis direction and the position of a table in an X-axis direction, the position of the spindle head 118 about a B-axis is determined. Then, the ram 34 is moved along the Z-axis direction with the spindle unit 100 revolved about the C-axis, and, with a non-rotational cutting tool 170 attached to the spindle unit 100, a hole is bored in a workpiece W on the table.</p> |
