摘要

The machine has a worktable (18) movable along the Y axis, and two rows of four machining heads (33) fitted to a common carriage (44) movable along the X axis. The circuit boards (9) are arranged in packs (24), each having two locating pins (28, 29) for aligning and locking the pack (24) to a respective rectangular fixture (38) fitted to the worktable (18) with the short side (39) parallel to the Y axis. Each pair of heads (33) is provided with a pair of tool-change devices (72) and a common tool store (54), which is defined by one or two boxes (57) removably insertable inside respective supports (56) fitted to the carriage (44); three pairs of tool-change devices (72) are housed inside gaps (42) between adjacent pairs of fixtures (38); and a further two pairs of tool-change devices (72) are located adjacent to the end fixtures (38).
